Ruffini corpuscles respond to sustained pressure [4] and show very little adaptation. [ 5 ] Ruffinian endings are located in the deep layers of the skin, and register mechanical deformation within joints, more specifically angle change, with a specificity of up to 2.75 degrees, as well as continuous pressure states.
Angelo Ruffini (Pretare of Arquata del Tronto; 1864–1929) was an Italian histologist and embryologist. He studied medicine at the University of Bologna , where beginning in 1894 he taught classes in histology .
Cutaneous receptors are at the ends of afferent neurons. works within the capsule. Ion channels are situated near these networks. In sensory transduction, the afferent nerves transmit through a series of synapses in the central nervous system, first in the spinal cord, the ventrobasal portion of the thalamus, and then on to the somatosensory cortex.
The Slowly Adapting type 2 (SA2) mechanoreceptors, with the Ruffini corpuscle end-organ (also known as the bulbous corpuscles), detect tension deep in the skin and fascia and respond to skin stretch, but have not been closely linked to either proprioceptive or mechanoreceptive roles in perception.
