Öğe Akkaraman Koyunu ve Ankara Keçi?si?ni?n Plexus Lumbosacrali?s'i Üzeri?nde Karşılaştırmalı Makroanatomi?k ve Subgros Çalışmalar(Selçuk Üniversitesi, 1992 Ocak) Erden, HasanIn this study, the comparative macroanatomical and subgross studies on the lumbosacral plexus of the Akkaraman sheep and Angora goat were investigated. For this purpose, eight Akkaraman sheep and eight Angora goats, in different sex, were used. It was observed that there wasn't a significant difference in the cources and distributions of the nerves arising from the lumbosacral plexus in Akkaraman sheep and Angora goat. On the contrary, there was significant differences in the origination of the nerves arising from the lumbosacral plexus between two species and individual member of the species.Öğe Akkaraman Koyununda Lymphonodi Cervicales Superficiales ve Lymphonodi Popli?tei?'ni?n Afferent ve Efferent Damarları Üzeri?ne Makroskopi?k Araştırmalar(Selçuk Üniversitesi, 1992 Mart) Tıpırdamaz, Sadettin; Dursun, Necdet; Erden, Hasan; Gezici, Memduh; Nur, İ. HakkıIn this study, numbers and the courses of the afferent and efferent lymph vessels of the cervical superficial node and popliteal lymph node were investigated in Akkaraman sheep. As a material, eight Akkaraman sheep were used. Four or six afferent lymph vessels enter to the cervical superficial lymph node. The efferent lymph vessels leaving from this node, are three in number and these vessels joined together with each other, forming a single lymph vessel. Efferents on the left side terminate in the external jugular vein. On the right side, the efferents terminate in the right lymph duct. It was seen that 4 or 6 afferent lymph vessels entered to the popliteal node and one efferent leaved from this node. Efferent on the right and left side goes to the medial iliac lymph node.Öğe Akkaraman Koyununda Sinus Durae Matris ve Ekstrakrani?al I?li?şki?leri? Üzeri?nde Makroanatomik Araştırmalar(Selçuk Üniversitesi, 1993 Ocak) Erden, HasanThe dural sinuses of Akkaraman sheep and their connections with veins of the head and neck were studied by macroanatomic observations. Information obtained from gross dissection supports the idea suggesting the cavernous sinus plays a very significant role in the termoregulation of the brain, since it has been a critical anatomical position and connections with the extracranial veins.Öğe Akkaraman Koyununda Uters'un Lenfati?k Drenaji Üzeri?nde Makroanatomik Çalışmalar(Selçuk Üniversitesi, 1994) Tıpırdamaz, Sadettin; Dursun, Necdet; Daşçı, Zafer; Türkmenoğlu, İsmail; Erden, HasanIn this study, numbers and the courses of the lymph vessels providing the lymphatic drainage of the uterus were macroscopically investigated in Akkaraman sheep. In this purpose, as a material, eight Akkaraman sheep were used. The lymphatic vessels are closely as- sociated with ovarian arterial supply. There was no direct lymph flow from the uterus to the ovary. It was seen that the lymph vessels of providing the lymphatic drainage of the uterus drained into the medial iliac lymph nodes.Öğe Ankara Keçisinde Lymphonodi? Cervi?cales Superfi?ci?ales ve Lymphonodi? Poplitei'nin Afferent ve Efferment Lenf Damarları Üzeri?nde Makroanatomik Araştırmalar(Selçuk Üniversitesi, 1993) Tıpırdamaz, Sadettin; Dursun, Necdet; Erden, Hasan; Daşcı, ZaferIn this study, the numbers and the courses of the afferent and efferent lymph vessels of the cervical superficial and popliteal lymph node were macroscopically investigated in Angora goats. In this purpose, as a material, eigth Angora goats used. were Four or five afferent vessels, starting as blindended vessels at the level of medial phalanx, entered to the cervical superficial lymph node in Angora goats. One efferent lymph vessel, leaving from this lymph node, drained into jugular trunc on the left side and venosus angle on the right side. Six or seven afferent vessels, starting bilaterally dorsal common digital nerve III and IV at the proximal level of the corium limbi entered to the each popliteal node and two afferent lymph vessels leaving from the popliteal node drained into ischiatic lymph node.Öğe Bi?r Köpekte Arcus Aortae'nin Farklı Dallanma Olgusu(Selçuk Üniversitesi, 1989 Ocak) Tıpırdamaz, Sadettin; Gezici, Memduh; Erden, HasanIt was observed that the aortic arch distributed distinctly in only one case, in different sex of fourty adult dogs was used to study in the Department of Anatomy. In this case, the common carotid arteries, left and right, have arisen from the aortic arch as the first branch, and have formed a common trunk. The left and right subclavian arteries arise from the aortic arch, in a common trunk.Öğe Bronz Hi?ndi?ni?n (Meleagris Gallopavo) Kemi?kleşmi?ş Baldır Kas Tendoları Üzeri?nde Anatomi?k Araştırmalar(Selçuk Üniversitesi, 1992 Mart) Erden, HasanIn this study, the localizations of the ossified tendons of the shank muscles were macroanatomically investigated in Bronze turkey. For this purpose, ten adult turkey were used. In this study, four on the origo tendons and fourteen on the insertio tendons, totally eighteen ossified regions were determined in each shank. In addition, it has been also found that all tendons of the muscles located in tar- sometatarsal region were to be ossified.Öğe Deve Midesi Üzerinde Makroanatomik Araştırmalar(Selçuk Üniversitesi, 1998) Erden, Hasan; Öcal, M. Kamil; Güzel, Necdet; Kara, Erkut; Öğüt İlknurWork was undertaken ıo elucidale the macroanalomic details ol the stomaeh of the came!. Filteen adull heaUhy one-humped camels (Camelus dromedarius) were used. The abdominal organs were kepı in situ and their relations LO Ihe slomaeh were examined. The anatomi slructure ol the camel slomaeh was eompared in other ruminants, and the luncUonal slgnificance of the differences is discussed. It was observed that the stomaeh ol ıhe eamel is composed ollour compartments (rumen, reticulum, omasum and abornasum), as in all ruminanls. On the contrary, they diller greally In shape and struclure from the typical design encounlered in the ruminants. It has a capacity of approximately 80 Iilres. Iı extended from the dlaphragm to the pelvie inlet and occupled the major portion of the abdominal cavity. The rumen was divided into a relalively smail cranioventral and a large caudodorsal sacs. The cranleventral sac was composed ol so-called Water sac' or 'glandular sac' and non glandular area. Intemally the glandular sacs consist of smailer compartments divided by strong Iongitudinal bands and most of these compartments are again S\Jb-divided by transverse bands, thus glving them a honey comb appearance. The mucous membrane of the rumen was not studded with papillae. The reticulum is a pear shaped organ and unlike other ruminanl. The mucous membrane of the relicutum formed deep pouches which are separated from each other by muscular bands. Each pouch was again divided and sub-divided to form many layers. The mueous of the pouches are studded with very smail rounded papillae. It was determined that there is a metallic ring one of the eamel reticulum. The omasum was a long colon·shaped organs and very dillereni from the omasum of the other domestic ruminants. The mucous membrane was thrown into about 50-60 longltudinal folds which gives a leafy appearance to this organ. Intemally the abomasum was divided inıo fundie and pyloric parts.Öğe Evci?l Memeli? Hayvanlarda Kalp Kas Köprüleri? Üzeri?nde Makroskopi?k ve Mi?kroskopi?k Araştırmalar(Selçuk Üniversitesi, 1992 Mart) Dursun, Necdet; Tıpırdamaz, Sadettin; Erden, Hasan; Çelik, İlhami; Aştı, Reşat N.In this study, myocardial bridges in the hearts of various domestic animals were described and classified by means of macroscopical and microscopical observations. In the classification of the bridges, special attention was given to the location, width and thickness of the bridge. In microscopical observations in the bridges were classified by regarding the number of the comminant veins of the overbridged artery. As a material, 15 Akkaraman sheep, Angora goats and cattle, 8 dogs and Water buffalo hearts were used. In all hearts of the various domestic animals species investigated in this study, the myocardial bridges were observed macroscopically on the ramus interventricularis paraçonalis and subsinuosus, on the first grade ramus of a ramus interventricularis and on the second grade ramus of a ramus interventricularis.Öğe Köpekleri?n Plexus Brachi?ali?s'i? Üzeri?nde Makro-Anatomi?k Araştırmalar(Selçuk Üniversitesi, 1988 Ocak) Tıpırdamaz, Sadettin; Erden, HasanIn this study, the formation and distribution of the brachial plexus of the dog was investigated. For this purpose, ten dogs, in different ages and sex, were used. The brachial plexus of the dog is formed by the ventral branches of the sixth, seventh, eighth cervical and first, second thoracic nerves. The ventral branch of the second thoracic nerve is relatively small. The nerves arising from the brachial plexus of the dog: Suprascapular nerve is formed by the ventral branches sixth and seventh cervical nerves in dogs. Subscapular nerves usually number two in this study, it is determined that subscapular nerves, only one cases (10 %) are three in number, nine cases are two in number. When two subscapular nerves are present, one of them arises from the ventral branches of the sixth and seventh cervical nerves, the other originates from the ventral branch of the seventh cervical nerve. Musculocutaneus nerve arises from the ventral branches of the seventh cervical nerve, with a delicate branch contribution from the sixth cervical nerve. Axillary nerve takes its origin from the ventral branches of the seventh and eighth cervical nerves. Cranial pectoral nerves are two in number. One of them, at its origin it is associated with the musculocutaneus nerve. Caudal pectoral nerves are two in number. At its origin, they are associated with the lateral thoracic nerve, and arise from the ventral branches of the eighth cervical and first and second thoracic nerves. Lateral thoracic nerve takes its origin from the ventral branches of the cervical and first and second thoracic nerve. Thoracodorsal nerve is formed by the ventral branch of the eighth cervical nerve. Long thoracic nerve originates from the ventral branches of the seventh and eighth cervical nerves. Radial nerve is formed by the ventral branches of the eighth cervical and first and second thoracic nerves. It is the largest nerve of the brachial plexus. Median nerve takes its origin from the ventral branches of the eighth cervical and first and second thoracic nerves. At its origin it forms a single trunk with ulnar nerve. Ulnar nerve takes its origin from the ventral branches of the eighth cervical and first and second thoracic nerves.Öğe Köpekte beyin arterleri(1997) Erden, Hasan; Dursun, Nejdet; Türkmenoğlu, İsmailKöpek, beyin arterlerini konu edinen araştırmalarda sıkça kullanılmıştır. Bu çalışmada da 14 adet erişkin Kangal köpeğinin beyin arterleri, renklendirilmiş latex ile doldurulmak suretiyle incelenmiştir.

Materyal olarak her iki cinsiyette toplam 14 adet köpek kullanılmıştır. Boyun damarları a. carotis communis'ten renklendirilmiş latex enjekte edilmek suretiyle doldurulmuştur. Boyunun başlıca a. vertebralis, tr. costocervicalis, a. cervicalis superficialis ve a.carotis communis'ten ayrılan damarlar tarafından beslendiği, bununla birlikte a. laryngea cranialis'in a. thyroidea cranialis ile, a. occipitalis'in ise a. vertebralis ile yaptıkları anastomozlar aracılığı ile, a. au-ricularis caudalis'in de ramus sternocleidomastoideus isimli dalı ile boyunun vaskularizasyonuna katıldıkları saptanmıştır. Ayrıca üç köpekte a. brachiocephalica'dan orijin alan küçük bir dalın varlığı da tesbit edilmiştir.Öğe Köpekte Extrakrani?al Arterler(Selçuk Üniversitesi, 1997 Aralık) Türkmenoğlu, İsmail; Erden, Hasan; Dursun, NejdetIn this study was undertaken to determine the arterial vascularisation of the head of Turkish shepherd dog. As a material, fourteen adult dogs were used. The external carotid artery that the main source of the blood supply to the head of the dog has been determinated by means of coloured latex injected through the common carotid artery.Öğe Merkebi?n (Equus Asinus L.) Plexus Lumbosacrali?s Üzeri?nde Makroanatomik ve Subgros Çalışmalar(Selçuk Üniversitesi, 1993 Ocak) Erden, HasanIn this study, the lumbosacral plexus of the donkey was investigated macroanatomically and subgrossly. For this purpose, eight donkeys in different sexes were used. The results showed that one animal had four, five animals had five, two animals had six lumbar vertebrae. Therefore, the significant differences in both the formation of the lumbosacral plexus and the spinal nerves arising from the plexus were also determined On the contrary, there were no significant differences in the course and distribution patterns of the spinal nerves arising from the lumbosacral plexus among the donkeys studied and also between results of previous workers who have studied on the horse.Öğe Zeranol'un Merinos Kuzularının Erkek Genital Si?stemleri? Üzeri?ne Etki?leri?(Selçuk Üniversitesi, 1989 Ocak) Tıpırdamaz, Sadettin; Acet, Ahmet; Erden, Hasan; Kadak, RamazanIn this study, fourty-five merino lambs were used. These animals were divided into there groups. Twelve mg of Zeranol were implanted subcutaneously to ear of the first and second groups lambs. Fourty days later, the same dose of Zeranol was reimplanted to the second group lambs. The remaining 15 lambs were served as nonimplanted controls. Five lambs belonging to each group were slaughtered at 80, 120 and 160 days after implantation. Before slaughtering the lambs body weight were measured. Then testes, epididymides, vesicular glands and bulbourethral glands were weighted. The testes weights and their ratio to the body weights in the Zeranol implanted groups slaughtered at the 80 th days were significantly lower than the control group. No differences were found in testicular of lambs slaughtered at the 120 th and 160 th days. On the other hand, any significant differences were not observed in the bulbourethral glands, vesicular glands and epididymal weights between the three groups.
