Sensory nerve endings in monkey hip joint capsule: a morphological investigation.
This study was undertaken to identify the sensory nerve endings in the monkey hip joint capsule. The capsules from six monkeys were stained in bulk by using a modified gold chloride method. Three morphologically distinct nerve endings: Type I, II and IV receptors resembling Ruffini end organs. Pacinian corpuscles and free nerve endings, respectively, were identified. The results showed that the hip joint capsules were densely innervated. Based on the present findings it is suggested that the monkey hip joint capsule is endowed with several types of afferent nerve endings, thus providing the anatomical basis for discriminating afferent outflow to the central nervous system.
