ORIGIN AND ANTIMERIC DISTRIBUTION OF THE FEMORAL NERVES IN NEWBORNS GOATS OF THE SAANEN BREED

The femoral nerves were studied in newborn goats of Saanen breed (22 males and 11 females) that were collected after natural death and fixed with 10% formaldehyde solution. In males the femoral nerve arose from the ventral spinal branches of L4 and L5 in eight animals (36%); in six animals (27%) it arose from the ventral spinal branches of L5 and L6; in five animals (23%) it arose from the ventral spinal branches of L5; in two animals (9%) it arose from the ventral spinal branches of L4, L5 and L6 and in one animal (5%) it arose from the ventral spinal branches of L5 and L6 and the ventral spinal branches of S1. In females the femoral nerve arose from the ventral spinal branches of L4 and L5 in seven animals (64%); in three animals (27%) it arose from the ventral spinal branches of L5 and L6 and in one animal (9%) it arose from the ventral spinal branches of L4, L5 and L6. In all animals, the femoral nerves were distributed in different branches to the major and minor psoas, femoris quadriceps, sartorius and pectinius muscles.

本研究对经10%甲醛溶液固定的自然死亡新生萨能山羊（Saanen breed）的股神经展开解剖学研究，共纳入33只实验动物，其中雄性22只、雌性11只。雄性个体中，8只（36%）股神经起自L4与L5的腹侧脊支；6只（27%）起自L5与L6的腹侧脊支；5只（23%）起自L5的腹侧脊支；2只（9%）起自L4、L5与L6的腹侧脊支；另有1只（5%）的股神经起自L5、L6以及S1的腹侧脊支。雌性个体中，7只（64%）股神经起自L4与L5的腹侧脊支；3只（27%）起自L5与L6的腹侧脊支；1只（9%）的股神经起自L4、L5与L6的腹侧脊支。所有受试动物的股神经均发出多支分支，分布于腰大肌、腰小肌、股四头肌、缝匠肌与耻骨肌。
