Sweat gland in skin

Sweat gland in skin. Light micrograph of a section through the dermis of the skin showing a sweat gland. The gland is composed of a secretory portion (upper left) and several excretory ducts (bottom left to top right). The dermis contains numerous sweat glands, which discharge a watery secretion onto the surface of the skin in order to lower the body temperature. Surrounding the secretory portion are myoepithelial cells (solid purple lines). These contract to expel sweat from the secretory portion into the ducts. Trichrome blue stain. Magnification unknown


Brain Featured 12 Jun 2002 Image


Brain. Computer artwork of a human brain in a male wire-frame head. The brain is the nerve centre controlling bodily function and thought. It interprets nerve signals received from the rest of the body and initiates the appropriate responses. Most of the visible surface consists of the folds of the cerebral cortex, the region responsible for intelligent thought, language, conscious movement and memory. The cerebral cortex partially covers two structures at the rear base of the brain. The cerebellum (left of ear) controls balance, posture and muscular co-ordination. The rod-like brainstem (right of cerebellum) controls vital subconscious functions, including breathing and blood pressure
