Cutaneous sensory nerve formations: An overview

Ratiometric calcium concentration estimation using LED excitation during mechanotransduction in single sensory neurons

“…Evidence for calcium involvement in vertebrate cutaneous mechanoreception is indirect, based on morphological labeling of calcium ions, calcium pumps and calcium binding proteins (Pawson et al, 2000;Vega, 1996). Calcium is thought to enter crayfish stretch receptor neurons through the mechanically activated ion channels and cause adaptation by acting on calcium-activated potassium channels (Erxleben, 1993).…”

Presence of sensory nerve corpuscles in the human corpus and cervix uteri during pregnancy and labor as revealed by immunohistochemistry

“…Sensory corpuscles are classified in different ways in the literature, and even within a certain classified type the appearance can vary [ 13 ]. Nevertheless, the corpuscles that were found to be distinctly encapsulated in the present study, with a distinct capsular p75 immunoreaction, closely resemble small Pacini-corpuscles [ 24 - 26 ]. On the other hand, the corpuscles that had an incomplete capsule, with an indistinct capsular p75 immunoreaction, to a certain extent resemble the Ruffini type of corpuscles [ 22 ], where the perineurium of the supplying nerve fascicle creates an incomplete perineurial capsule around the corpuscles [ 26 ].…”

Propioceptores articulares y musculares

“…A pesar de que clásicamente se describen diferentes morfotipos de receptores sensitivos articulares, algunos autores consideran que todos ellos son, en realidad, un continuum, dependiendo su morfología de la adaptación o las condiciones locales (ver para ref. 39,123). En este sentido se ha llegado a afirmar que los corpúsculos de Ruffini que se encuentran en las articulaciones son prácticamente idénticos a los órganos tendinosos (40,41,43).…”
