The Integumentary System The Skin Biology Diagrams The purpose of this comprehensive review is to: 1) review the physiology of sweat gland function and mechanisms determining the amount and composition of sweat excreted onto the skin surface; 2) provide an overview of the well-established thermoregulatory functions and adaptive responses of the sweat gland; and 3) discuss the state of evidence for potential non-thermoregulatory roles of sweat The sympathetic nerves distributed to sweat glands consist of large numbers of cholinergic terminals and a few adrenergic Young AJ, Muza SR, Pandolf KB, Latzka WA, Dennis RC, Valeri CR. Polycythemia and hydration: effects on thermoregulation and blood volume during exercise-heat stress. Am J Physiol. 1988;255:R456-463. doi: 10.1152
In humans, evaporative heat loss from eccrine sweat glands is critical for thermoregulation during exercise and/or exposure to hot environmental conditions, particularly when environmental temperature is greater than skin temperature. Since the time of the ancient Greeks, the significance of sweating has been recognized, whereas our understanding of the mechanisms and controllers of sweating Research into sweat glands, thermoregulation, and hydration has expanded our understanding of how sweating impacts overall well-being. Exploring these aspects reveals insights into the importance of staying hydrated and maintaining optimal skin function. Eccrine Sweat Glands.
Neural control and mechanisms of eccrine sweating during heat stress ... Biology Diagrams
Eccrine sweat glands are simple, coiled, tubular glands present throughout the body, most numerously on the soles of the feet. Thin skin covers most of the body and contains sweat glands, hair follicles, hair arrector muscles, and sebaceous glands. Given the role of sweat glands in thermoregulation, both eccrine and apocrine glands have
Despite the well-accepted thermoregulatory role of sweating, it is common perception that sweating has a variety of other critical homeostatic functions unrelated to thermoregulation. For instance, sweat glands are perceived to play an important excretory function, similar to that of the renal system, responsible for clearing excess Basic structure. In general, sweat glands tend to comprise a secretory unit which is located either in the deep dermis or in the subcutaneous tissue, and a duct which continues from the secretory unit towards the body surface, through which sweat or secretory product is passed.. The secretory units of sweat glands are surrounded by contractile myoepithelial cells which act to help secrete the A sweat gland is a specialized exocrine gland in the skin that produces and secretes sweat, primarily composed of water, salts, and waste products. Sweat glands are essential for regulating body temperature and excreting metabolic waste. There are two main types of sweat glands: eccrine glands, which are responsible for thermoregulation, and apocrine glands, which
Physiology of sweat gland function: The roles of sweating and sweat ... Biology Diagrams
Human thermoregulation depends significantly on sweat evaporation from the skin surfaces. This becomes clear when sweating is inhibited during periods of hard physical labour or being subjected to hot conditions[1]. Although sweating is widely believed to play a thermoregulatory role, it also serves several other minor homeostatic roles. For instance, it is believed that sweat glands
