普通刺猬的解剖学研究(一) 被皮

Studies on Anatomy for the Hedgehog(Erinaceus europaeus) Integument Ⅰ

对状28只（雌16，雄12）成年普通刺猬（Erinaceuseuropaeus）的被皮进行了解剖学研究，结果表明，普通刺猬被皮有丰厚的皮下脂肪和发达的皮下肌，雄性被皮占体重的38．02％．雌性占44.29％；雄性皮下脂肪占体重的6.88％,雌性占12．04％，雌性皮肤重和皮下脂肪重均显著高于雄性（P＜0.05或0.01）．皮肌和刺重无性别差异。除面部、四肢和腹部外，全身披有粗而硬的针刺．针刺长（16．36±1．30mm．直径（0．95±0．15）mm．重（3．55±0．43）mg。每只普通刺猬有针刺（5434±475）根。针刺按颜色分有五种类型，不同个体身上这五种针刺的分布比例不等。普通刺猬有乳腺5对．前后足各5指（趾）．指（趾）端具爪。普通刺猬皮肤的特殊结构，具有重要的生理保护意义。关征词##4刺猬;;解剖学;;

The integument samples from the 28 adult hedgehogs (Erinaceus europaeus ) (♀16, ♂12 ) wercstudied by the method of anatonly. There are rich and thick subcutaneous fat and developed integurmentalmuscle in the hedgehog in teguments. The weight of the integument of the hedgehog is about 38. 02 % times of the body weight for male and 44. 29% for female respectively. The weight of the subcutaneous fat is6. 88%times of the body weight for male and 12.04 % for femalc respectively. There are distict difference for the weight of the integument and subcutaneous fat between male and female (P<0.05 or0.01), there is no distinct difference for the weight of the integumental muscle and spiny halr between male and female. Apart from the face,the four limbs and the abdomen, therc are full of the thick and stiff spiny hairs in the skin of the hedgehog. The length of the spiny halr is (16. 36 ±1. 30)mm, the diameter (0. 95±0.15 )mm, the weight (3. 55±0. 43 )mg. There are (5434±475 ) spiny halrs in the skin of the hedgehog. According to the colour, the sping hairs are divided into flvc typs whch arc distributcd in different ration in every hedgehog. There are five pairs of mammary glands in the hedgehog. There are five toes in the hand and foot,there is a claw in theend of the each toe. The peculiar structure of the hedgehog integument is very useful for hedgehog's physiological protection.
