Skin nerve impulses initiated in mechanoreceptors are transmitted along type B fiber
These detect mechanical deformation e.g. touch or pressure within the skin; stretch receptors in muscles. * mechanoreceptor cells answer a change in the external stimulus (pressure, temperature, etc) by producing voltage pulses across neurons (i.e. generator potentials)
Mechanoreceptors are sensory neurons or peripheral afferents located within joint capsular tissues, ligaments, tendons, muscle, and skin. Four primary sorts of afferent mechanoreceptors are commonly present in noncontractile capsular and ligamentous structures in human joints: types I, II, III, and IV
First-order neurons receive impulses from skin and proprioceptors and send them to the medulla spinalis . They then synapse with second-order neurons. Second-order neurons sleep in the dorsal horn and send impulses to the thalamus and cerebellum
