The nail acts as a counterforce to the fingertip, providing even more sensory input when an object is touched. Dermis. The nail plate is the actual fingernail, composed of translucent keratin. These are connected to the hair follicles over the skin. In other words, sweating causes the loss of body heat and thus cools us down on a hot day or when performing strenuous exercise. There are more than 2.5 million sweat glands in the body, and there are two different types: apocrine and eccrine.2 Apocrine sweat glands are found in the more odorous part… Pituitary gland.

Earwax: Sweat and Cerumen Glands: Part 3 Glands of the Skin of the Ear Canal Figure 1. Neither function is all that relevant or useful in humans, although some warmth is provided by scalp hair. By combining galvanic skin conductance (GSC), stratum corneum hydration (HYD) and regional surface sweat rate (RSR) measurements at the arm, thigh, back and chest, we closely monitored the passage of sweat from gland to skin surface. Each sweat gland is made up of two portions: The secretory portion is found in the dermis, the middle layer of the skin. Sweat glands are found throughout the skin but are more numerous in areas such as the soles of the feet, palms of the hand, armpits and groin. Then, the long section of the gland that extends from the coiled portion, often referred to as a duct, allows the sweat to move from the base toward the surface of the skin. Correct!

It is the junction between the free edge of the nail and the skin of the fingertip, also providing a waterproof barrier. The outer (cartilaginous) one-third portion of the ear canal (shown in red) is the location for the production of cerumen (earwax). The root is part of the hair enclosed by the hair follicle, which is itself a tube-like involution of the skin. They are typically larger than eccrine glands and their ducts tend to open into hair follicles instead of hairless areas of skin. Eccrine Glands: The Eccrine Glands are distributed all over the body but are found mostly in the palm of the hands, soles of the feet, and the forehead. Sebaceous Gland: Schematic view of a hair follicle with sebaceous gland. Meaning, it ensures our hair doesn’t become too dry and brittle. The secretions of apocrine sweat glands contain more fat and protein than do the secretions of eccrine sweat glands. Hair follicle: Cross section of a hair follicle. Sweat glands are tubes in which sweat is produced and then transported to the surface of the skin. Just like the eccrine, apocrine glands are coiled tubes that are in the dermis. The perioncyhium is the skin that overlies the nail plate on its sides; it is also known as the paronychial edge.

Hair growth occurs from the hair follicle. There are 3 main types of glands found on human skin: • Eccrine glands - secrete sweat through pores found in the palms of hands, soles of feet, and forehead • Sebaceous glands - secrete oily sebum and are found on the chest, back, scalp, face, and forehead • Apocrine glands - secrete sweat … What are the three main functions of integumentary system?

This layer is composed of scale-like cells that seem to overlap in a shingle-like manner. The hair bulb has a growth zone called the matrix. The nail bed contains the blood vessels, nerves, and melanocytes, or melanin-producing cells. The root of the fingernail is also known as the germinal matrix. The structure of the hair follicle includes the papilla, matrix, root, and bulb. It does so by preventing the excess evaporation of water from the skin. The nail bed is a part of the nail matrix called the sterile matrix. The oil they produce lubricates skin and hair and can also contribute to skin problems like pimples. The fingernail generally serves two purposes: it acts as a protective plate and enhances sensation of the fingertip. These names are derived from the latin word ‘sudor’ which means ‘sweat’. https://en.wikipedia.org/wiki/Eccrine_sweat_gland, http://en.wikibooks.org/wiki/Human_Physiology/Integumentary_System, http://en.wikipedia.org/wiki/Sebaceous_glands, http://en.wikipedia.org/wiki/Nail_(anatomy), http://en.wikipedia.org/wiki/Hair_follicle, http://en.wikipedia.org/wiki/hair%20fiber.

The sebaceous glands are located in the dermis, the middle layer of the skin, and they develop from the epithelial cells of the hair follicle itself (the external root sheath of the hair follicle). Eccrine sweat glands secrete a salty solution (sweat), which reaches the skin pores via an eccrine duct. The sweat produced may be acted upon by bacteria, causing a noticeable odor. Their function is to secrete a substance called sebum, a mixture of fatty substances, entire sebum-producing cells, and epithelial cell debris. The epidermis of the skin has a number of appendages which maintains the integrity of the skin and help it carry out its various functions. It extends from the edge of the germinal matrix, or lunula, to the hyponychium. The hair follicles, sweat and sebaceous glands are epidermal structures which are pushed into the dermis where it is rooted. The eccrine sweat glands are located throughout the body and produce a thin fluid of water and electrolytes (eccrine sweat).
