鹌鹑胸大肌的肌纤维在肌纤维的中部三分之一处有一个神经肌肉接头。孤立纤维的长度在8.8和33.2 mm之间变化,平均值和中位数分别为16和15.6 mm。从其中的纤维被隔离的束的长度在30和51毫米之间变化。肌纤维在两端逐渐变细。的神经肌肉接头,组织化学反应后显示的完整的肌肉乙酰胆碱酯酶活性,被安排在离散的带,分开的间隔为0.94和6.70毫米之间,平均值为3.14毫米。鹌鹑胸肌,因此,由不连续的,锥形的肌纤维,安排在一个重叠的系列。因此,它是一种张力在肌纤维之间横向传递的肌肉。
The twitch fibers of the quail pectoralis muscle were found to have one neuromuscular junction each, located in the middle third of the fiber. The length of isolated fibers varied between 8.8 and 33.2 mm, with mean and median values of 16 and 15.6 mm, respectively. The lengths of the fascicles from which the fibers were isolated varied between 30 and 51 mm. The muscle fibers taper at both ends. The neuromuscular junctions, revealed after histochemically reacting the intact muscle for acetyl cholinesterase activity, were arranged in discrete bands, separated by intervals of between 0.94 and 6.70 mm, with a mean value of 3.14 mm. The quail pectoralis muscle is thus composed of discontinuous, tapered muscle fibers, arranged in an overlapping series. It is therefore a muscle in which tension is transmitted laterally between muscle fibers.
