It is thinnest over the eyelids, penis, scrotum, and the ventral and medial body surfaces. The interfiber spaces contain small quantities of fat, hair follicles, nerves, oil glands and ducts of sweat glands. THIS region, among other factors, leads to differences in skin thicknesses over the body. The SQ layer contains Pacinian corpuscles. Before going further into the skin and its derivatives, let's examine 6 different receptor organs found in the skin.
Pacinian corpuscles are pressure receptors.
They are naked nerve endings in deeper tissue. They are found in the SQ under skin and mucous membranes, around joints, in mammary glands and in the external genitalia of both sexes. Nociceptors are pain receptors. They are naked nerve endings in all tissues in the body. They may respond to any type of stimulation.
