* '''dermomyotome''' - Early embryonic dorsolateral half of the somite that will later divide to form both the dermatome and myotome. The dermatome will contribute the dermis and hypodermis of the skin. The myotome will contribute the skeletal muscle of muscoloskeletal system. Development sequence: [[M#mesoderm|mesoderm]] to paraxial mesoderm to somite to "dermomyotome" then dermatome and myotome. (More?

* '''dermatome''' - The early embryonic dorsal portion of the somite that will contribute the dermis and hypodermis of the skin. Note in the adult, this term is used to the skin sensory region innervated by a single spinal (nerve) segment.

* '''eccrine gland''' (Greek, ''ekkrinein'' = "secrete"; merocrine glands) sweat glands unique to some primates and used in humans for thermoregulation. Adult body has 2 to 4 million sweat glands with concentrations (700/cm) on the palms of the hand, soles of the feet and forehead. | * '''eccrine gland''' (Greek, ''ekkrinein'' = "secrete"; merocrine glands) sweat glands unique to some primates and used in humans for thermoregulation.

* <span id="Term-epidermis">'''epidermis'''</span> - Histological term describing the external cellular epithelial layer of the integumentary (skin) covering the entire body. This surface layer of keratinocytes is [[E#ectoderm|ectoderm]] in origin, while the underlying connective tissue layers of [[D#dermis|dermis]] and [[H#hypodermis|hypodermis]] are [[M#mesoderm|mesoderm]] in origin.
