摘要: Barker (1974) gives a comprehensive review of the anatomy muscle receptors mammalian and nonmammalian vertebrates. In vertebrates, all skeletal, smooth heart muscles are innervated by free nerve endings. They supplied nonmyelinated axons (0.2–1 μm in diameter; classified into group C vertebrate or IV mammals), some thin myelinated (2–6 μum Aδ vertebrates general III II mammals). The endings consist numerous parallel varicose threads either on surface extrafusal fiber tendon, lying connective tissue joint capsule as well spindle sensory ending frogs (cf. 1974). number length terminal branches varies widely between species even individual preparations.
