Sweat Glands
The Sweat Glands
There are on average 2.6 million sweat glands to be found in the skin of a person. They are distributed over the whole body – apart from the nipples, lips and external genitals. The sweat gland is located in a layer of the skin called the dermis, nerve endings and hair follicles are also found in the same layer.
The sweat gland is a coiled tube, hollow and a rather long cell, the coiled part is where sweat is produced, the longer part connects the gland to the opening on the outer surface of the skin. Nerve cells connect to the sweat glands. There are two types of sweat glands to be found within the body.
• Eccrine – the most common type and is found all over the body, especially in the palms of the hands, the soles of the feet and the forehead
• Apocrine – mostly found at the armpits and the anal region of the genital area. They normally end in hair follicles rather than pores.
The two glands are different in size, and become active at a different age, the composition of the sweat they make is also different. Eccrine glands, compared to apocrine glands are smaller, are active from birth and the sweat they produce is free from proteins or fatty acids. Apocrine glands become active at puperty.
We sweat constantly, though we may not notice it at all times. It‘s the body‘s best way of getting rid of excess heat that is caused by metabolism and muscles. The volume of sweat being produced by the body depends mostly on our state of emotion and physical activity.
