【摘要】：目的觀察正常貓的眼外肌及其神經(jīng)支配的形態(tài)特點(diǎn),比較并分析與人的同名結(jié)構(gòu)在形態(tài)解剖上的異同。方法采用大體解剖學(xué)方法對8只幼貓和3具成年尸頭的眼外肌及神經(jīng)支配的起止點(diǎn)、走形、毗鄰行解剖學(xué)觀察,測量眼外肌的長度、肌腱的長度、肌止點(diǎn)的寬度和肌止點(diǎn)離角膜緣的距離。結(jié)果(1)貓的眼外肌除了具有眼球牽縮肌外,其余四條直肌(即上直肌、下直肌、內(nèi)直肌、外直肌)、兩條斜肌(上斜肌、下斜肌)和一條提上瞼肌跟人的同名結(jié)構(gòu)的起止點(diǎn),走形和毗鄰等特點(diǎn)相同。(2)貓和人的四條直肌中,肌肉長度和肌腱長度均是外直肌最長,內(nèi)直肌最短；肌止點(diǎn)寬的測量中,貓的內(nèi)直肌最寬,其次為外直肌,上直肌,下直肌最窄。人的內(nèi)直肌最寬,其次為上直肌、外直肌,下直肌最窄。(3)貓的眼眶內(nèi)的神經(jīng)分布、起止點(diǎn)、走行和毗鄰與人的眼眶內(nèi)同名結(jié)構(gòu)相似,但貓的額神經(jīng)沒有眶上神經(jīng)和滑車上神經(jīng)分支。結(jié)論貓的眼外肌及眶內(nèi)神經(jīng)的分布、起止點(diǎn)、走形和毗鄰跟人的同名結(jié)構(gòu)有較高的相似性,貓可以作為臨床上研究眼外肌及其神經(jīng)支配的實(shí)驗(yàn)動物。
[Abstract]:Objective to observe the morphologic characteristics of the extraocular muscle and its innervation in normal cats, and to compare and analyze the similarities and differences between the structures of the same name and those of the human. Methods the starting and ending points of extraocular muscle and nerve innervation of 8 kittens and 3 adult cadaveric heads were observed by general anatomy. The length of extraocular muscles and tendons were measured. The width of the muscle stop and the distance between the muscle stop and the limbus cornea. Results 1) in addition to the constrictor muscle, the other four rectus muscles (i.e. superior rectus, inferior rectus, internal rectus, external rectus), two oblique muscles (superior oblique, inferior oblique) and one levator palpebrae were the starting and ending points of the same name structure of the human being, the other four rectus muscles were superior rectus muscle, inferior rectus muscle, medial rectus muscle, external rectus muscle, superior oblique muscle and inferior oblique muscle. Of the four rectus muscles of cat and human, the length of muscle and tendon are the longest and the shortest of the external rectus and the inner rectus, and the width of the inner rectus of the cat is the widest, the second is the external rectus and the superior rectus. The inferior rectus muscle is the narrowest. The inner rectus muscle is the widest, followed by the superior rectus muscle, the outer rectus muscle and the inferior rectus muscle. But the cat's frontal nerve has no branch of the supraorbital nerve and the superior trochlear nerve. Conclusion there is a high similarity between the distribution of the extraocular muscle and the intraorbital nerve, the starting and ending points, the stride and the contiguous structure with the human. The cat can be used as a clinical experimental animal to study the extraocular muscle and its innervation.
