Hıfzısıhha Enstitüsü Serum Çiftliği 'nden temin edilen 7 adet 3 aylık, 11 adet
ergin toplam 18 adet (10 erkek, 8 dişi) kobayda diaphragrna makro-anatomik ve
subgros olarak incelendi. Diaphragrna'nın kassel bölümünün pars lumbalis'ini
oluşturan crus dextrum'un 1. -4., crus sinistrum lateraleve merliale'nin 1.-2. bel
omudanndan orijinaldığı saptandı. Pars costalis'in 6. -12 . costa'lann medial
yüzünden, pars stemalis'in de cartilago xiphoidea ile processus xiphoideus'un
birleşme yerinin iç yüzünden aynidığı gözlendi. Alan bakımından kassel kısımdan
daha geniş bir yüzeyi kaplayan centrum tendineuro 'um "V" harfi şeklinde olduğu
ve sağ tarafta foramen venae cavae tarafından delindiği görüldü. C rus dextrum,
crus sinistrum lateraleve mediale ile son sırt ve ilk iki bel omuruİıun ventral'i .
· tarafından oluşturulan hiatus aorticus'tan, aorta, vena azygos dextra ve ductus
thoracicus 'un, c rus dextrum ve c rus sinirstrum 'un şekillendirdiği hiatus
esophageus'tan da esophagus 'la birlikte truncus vagalis dorsalis ve truncus
vagalis ventralis'in geçtiği saptandı. Venae cavae caudalis'in ise centrum
tendineuro üzerindeki forarn en venae cavae 'dan geçtiği görüldü. Ergin kabaylarda cupula diaphragrnatis' in daha belirgin olduğu saptandı.

Macro Anatomy Of Diaphram In Guinea Pig (Cavia Porcellus)

Öz

Diaphragrn has been examined macroanatomically ·and subgrossly in the
eighteen guinea pigs (n: 10 male, 8 female) obtained from the Hıfzıssıha Institute
Serum Farm. The guinea pigs were 3 month- old (n:7) and adult (n: ll). It
was detected that the right crus of lumbar portion of diaphragrn's peripheral
muscle arose from first four lumbar vertebrae and the left crus divided laterally
and medially which originated from fırst and second lumbar vertebrae. The
costal part ofthe peripheral muscle took origin from inner surface ofthe 6 . -12 .
ribs, and stemal part from the dorsal surface between the xiphoid cartilage and
xiphoid process of stemum. The central tendon shaped "V" was larger than
muscular periphery. The ca va! foramen located the right of median plane and on the central tendon. It was permiting to the transmission of caudal vena ca va.
The aortic hiatus was present among the left lateral and medial crura and right
crura, and last thoracic, first two lumbar vertebrae. The aorta, thoracic duct
and azygos vein ~ere passing through the aortic hiatus. The esopiıageal hiatus
was seen between right and left crura, and there were esophagus and dorsalventral
vagal trunks in this hiatus. The cupula diaphragmatis was clear in the
adult guinea pigs.Key words: Macro anatomy, Diaphragm, gulinea pig.
