Sensory Nerve Endings in the Deep Lateral Cubital Region: A Topographical and Ultrastructural Study in the Rat
The connective tissue apparatus, as revealed in the human lateral elbow region by means of an alternative method of dissection — in which capsular ligaments can not be described as separate entities — appears to play an important role in conveying tensile stresses (Van Mameren, 1983; Van Mameren and Drukker, 1984). In the homologous region of the rat the role of this apparatus as to the quality of centripetal information was questioned (Van der Wal et al., 1984). There is growing evidence in the literature that a complete description of the morphological substrate of proprioception in a joint region should not be restricted to the joint capsule receptors alone but has to include the sensory nerve endings in the entire periarticular connective tissue, the muscle tissue and even in the skin (Halata et al., 1985, for review see Abrahams, 1983). Since one of the main conclusions of our previous investigations (Van der Wal et al., 1984) was, that in the studied region, almost all muscle tissue functions in series with this connective tissue and thus the usual concept — that muscles function in a parallel relation to the capsular connective tissue — is not correct for this region, the question was raised how the organisation of the morphological substrate of proprioception is related to the found architecture. Therefore an integral, three dimensional description of the occurrence of mechanoreceptors in relation to the architecture of muscle and connective tissue is needed, presenting the functional topography of the substrate that functions as the source of centripetal information.
