The word 'eccrine glands' refers to sweat glands in the human body that secrete fluids to regulate body temperature. It is pronounced /ˈɛkraɪn ɡlændz/ in IPA phonetic transcription. The 'e' in 'eccrine' is pronounced short, as in 'bed', and the 'ccr' is pronounced as 'kr'. The 'i' is pronounced as a short 'i', as in 'pit'. 'Glands' is pronounced with a soft 'g', and the 'a' is pronounced as in 'cat'. Overall, the spelling of this word can be quite confusing to those unfamiliar with its phonetic pronunciation.
Eccrine glands are small tubular structures found in the dermis, or the middle layer of the skin, which play a vital role in the human body's thermoregulation process. These glands are present all over the body, with the highest concentration in the palms of the hands, soles of the feet, and forehead, and they are specifically responsible for the production and excretion of sweat, a transparent, odorless, and watery substance.
Composed of coiled secretory cells, eccrine glands are innervated by the sympathetic nervous system and are activated by various stimuli, such as an increase in body temperature, physical activity, or emotional stress. Once stimulated, these glands secrete sweat onto the surface of the skin through tiny ducts. Sweat is primarily composed of water, electrolytes, and waste products, and it functions as a coolant for the body, helping to regulate body temperature through the process of perspiration and evaporation.
Notably, eccrine glands are distinct from apocrine sweat glands, which are larger and are found primarily in the armpits and genital regions. Unlike apocrine glands, which produce sweat that is thicker, with a stronger odor due to the presence of bacteria, eccrine glands produce sweat that is primarily water-based and does not have a distinct smell.
Overall, eccrine glands are crucial in maintaining the body's internal temperature by allowing for efficient cooling through the production of sweat, ensuring the body functions optimally and avoids potential overheating or hyperthermia.
The term "eccrine glands" is derived from the Latin word "eccrinus" and the Greek word "ekkrinein".
The Latin word "eccrinus" means "separate" or "distinct", while the Greek word "ekkrinein" means "to secrete". Together, these words represent the primary function of eccrine glands, which is to secrete sweat.
The concept of eccrine glands dates back to ancient Greece, where human anatomy and physiology were extensively studied. The term was later adopted into modern medical terminology to classify the specific type of sweat glands found in the human body.
