The apocrine glands are found in places like the armpits, scrotum, anus, and labia majora. They have two parts: an outer duct and inner sweat-secreting cells. The fingernail root produces most of the volume of the nail and the nail bed. Key Terms.

Both types of glands occur near the hair follicle. Sweat glands are found in the superficial hypodermis near the border of the dermis. Sebaceous glands and sweat glands are the two types of Sebaceous glands are the small glands in the skin that secrete lubricating oily matter, sebum into hair follicles. The present trend is to correlate the normal and the abnormal variations of the physiology and chemistry of the sweat gland with its histochemistry and histo-logic structure. If a sebaceous gland becomes infected, moderate and severe forms of acne are the result.The glands lining the ear canal that produce earwax (cerumen) are called ceruminous glands. The total number of sweat glands is somewhere between 2 and 4 million and only about 5% are active at the same time, indicating the enormous potential for sweat production.
These cells degenerate to release the contents into the duct. The hair bulb has a growth zone called the matrix. Eccrine sweat glands are one of two types of sweat glands found only in mammals. The duct of the sweat gland is also a coiled structure.

They are branched, acinar (spherical) glands found in mammals. Although every human has sweat glands, only females have glands and ducts capable of producing milk. There are two types of sweat glands, each secreting slightly different products. The other, apocrine glands, develop around hair follicles [source: Britannica]. Sweat is a watery fluid that is The apocrine sweat glands and eccrine sweat glands are the two types of sweat glands in the skin. The basic structure of human sweat glands consists of a coiled secretory region deep in the skin and then a tube or duct that conveys the sweat to a pore at the skin surface. The eccrine sweat gland is a long-branched tubular structure with highly coiled secretory portion and a straight ductular portion. These are the true sweat glands in the sense of helping to regulate body temperature. Sometimes it’s also found in the hypodermis, the deepest layer of our skin.The secretory portion of a sweat gland is a twisted and coiled tube that has an opening at its very top. The sebum is a fatty acid substance, secreted into the follicular duct and then to the surface of the skin. Difference Between Sebaceous Glands and Sweat Glands The perionychium is the site of hangnails, ingrown nails, and an infection of the skin called paronychia.The hyponychium is the area between the nail plate and the fingertip. It opens to the skin as a sweat pore. Their varying combinations are what help to produce the different natural hair colors people have.Depending on the kind of hair and location, hair can have one of several purposes:

However, some sebaceous gland ducts open directly onto our skin surface such as at the corner of the mouth and the glans penis. Sweat glands are the small glands in the skin that secrete sweat. A sebaceous gland is shown in The rounded cells in the sebaceous gland are filled with lipid vacuoles. The free margin or distal edge is the anterior margin of the nail plate corresponding to the abrasive or cutting edge of the nail.The eponychium, or cuticle, is situated between the skin of the finger; the nail plate fuses these structures together and provides a waterproof barrier.The perioncyhium is the skin that overlies the nail plate on its sides; it is also known as the paronychial edge. This is why they are also called the oil glands. It is supplied with nutrients via blood by a structure called the hair papilla. This is because as the water in sweat evaporates, it takes body heat with it.The other kind of sweat glands are known as apocrine glands. The infundibulum is part of the pilosebaceous canal, the one responsible for discharging sebum and one that is composed of the infundibulum and the short duct of the sebaceous gland itself.
Regardless, the secretion of sebum out of the gland is helped along by the contraction of the arrector pili muscle.While the sebaceous glands are present just about all over the skin, they are notably absent on the palms of the hands and the soles of the feet. It extends from the edge of the germinal matrix, or lunula, to the hyponychium. They are modified sebaceous glands.Fingernails are made of keratin and they perform two major functions: protection and sensation.The fingernail is an important structure made of keratin. We do know they are activated during times of stress, pain, and sexual foreplay but for what reasons is yet to be made clear.Sebaceous glands are found in most of the skin (except the palms of the hands and the soles of the feet).Describe the location and function of sebaeous glandsSebaceous glands are the oil secreting glands of your body. The pink appearance of the nail comes from the blood vessels underneath the nail. The edge of the germinal matrix is seen as a white, crescent shaped structure called the lunula.The nail bed is a part of the nail matrix called the sterile matrix. Their function is to secrete a substance called sebum, a mixture of fatty substances, entire sebum-producing cells, and epithelial cell debris.
