摘要
一、序言上肢的主要神经(桡神经、正中神经和肌皮神经)的肌支测量,前人Linell^([1]),Feintein,Highet,Hughes和Ray^([4-6])诸氏都先后作过,最早的要算Linell(1921)氏,但他仅测量某一肌支自发出点至肌肉之间的垂直距离,因而不能确知肌支纤维的真实长度,因为大多数肌支并非沿上肢某一水平垂直至肌肉的。此外,Linell也曾未注意到某一肌肉的若干肌支(多肌支的)源出处之间的距离的意义,因为这些肌支中的第一支并不是至某一肌的最短的一支。
The length of the muscular branches of the nerves in the upper limb from a fixed point along the nerve and its branches in 40 cadavours was measured.The muscular branches of the median and the radial nerve were measured by Sunderland’s method,while for the muscular branches of the musculo-cutaneous nerve,we selected the middle point of the clavicle as a fixed point.The shortest and the longest distances and the numbers of muscular branches to the individual muscles supplied by the nerves were re-corded.The point of origin of the muscular branches of individual muscles in each muscle group followed a definite order,for instance,the shortest of the muscular branches of the median nerve was those to the pronator teres,then next by order were those to the flexor digitorum sublimis,the palmaris longus,the flexor pollicis longus and the pro-nator quadratus.The serial order of branches from the radial nerve was that to the long head of the triceps brachii,the medial head of the same muscle,the brachialis,the extensor carpi radialis longus,and the extensor carpi radialis brevis.Among the muscular branches of the musculo-cutaneous nerve,those to the coracobrachialis came out first,then followed by those to the biceps brachii and the brachialis.The number of the branches to the individual muscles in each muscle group seemed to be proportional to the size of the muscle and to the role played by that muscle in the specific movement.The pronator and supinator muscles,though small in size,received quite a number of branches.It is suggested that the more muscular branches a muscle receives,the greater the importance it has in moving a joint.
