Light and Electron Microscopic Immunocytochemical Demonstration of Intraepidermal CGRP-Containing Nerves in Human Skin. The distribution of nerves immunoreactive to calcitonin gene-related peptide (CGRP) was studied in human skin with special reference to the intraepidermal nerve fibres. It was shown by light and electron microscopy that a small proportion of the CGRP immunoreactive nerves entered the epidermis. The majority of the nerves ended as free nerve terminals subepidermally. Intraepidermal nerve endings were mainly seen in skin areas, which have a dense sensory innervation, such as fingertips and foreskin. The role of the peptidergic nerves in human skin is discussed.

Small fiber peripheral neuropathy is a type of peripheral neuropathy that results from damage to the small unmyelinated and myelinated peripheral nerve fibers. These fibers, categorized as C fibers and small Aδ fibers, are present throughout human skin, peripheral nerves, and organs. Small fiber nerves receive somatic afferent signals (somatic afferents) and regulate components of the autonomic nervous system (autonomic efferents). It is estimated that 15–20 million people in the United States have some form of peripheral neuropathy.

In human anatomy, the penis (; pl.: penises or penes; from the Latin pēnis, initially 'tail') is an external sex organ (intromittent organ) through which males ejaculate and urinate. Together with the testes and surrounding structures, the penis functions as part of the male reproductive system. The main parts of the penis are the root, body, the epithelium, including the shaft skin, and the foreskin covering the glans. The body of the penis is made up of three columns of tissue: two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side. The urethra passes through the prostate gland, where it is joined by the ejaculatory ducts, and then passes through t…
