A sebaceous gland or oil gland[1] is a microscopic exocrine gland in the skin that opens into a hair follicle to secrete an oily or waxy matter, called sebum, which lubricates the hair and skin of mammals. [2] In humans, sebaceous glands occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of ...
The uropygial gland, informally known as the preen gland or the oil gland, is a bilobed sebaceous gland possessed by the majority of birds used to distribute the gland's oil through the plumage by means of preening. It is located dorsally at the base of the tail (between the fourth caudal vertebra and the pygostyle) and is greatly variable in ...
Meibomian gland. Meibomian glands (also called tarsal glands, palpebral glands, and tarsoconjunctival glands) are sebaceous glands along the rims of the eyelid inside the tarsal plate. They produce meibum, an oily substance that prevents evaporation of the eye's tear film. Meibum prevents tears from spilling onto the cheek, traps them between ...
Acne develops when sebaceous (oil) glands and hair follicles under the skin become clogged with oil, dead skin cells, and other debris. These blockages cause inflammation that can appear in a few ...
Areolar gland. The small bumps surrounding the nipple are areolar glands. Areolar glands, also known as glandulae areolares, Montgomery glands, and tubercula areolae, are 10-15 elevations found on the areola. They are usually arranged in a circle around the nipple, and can be particularly visible when the nipple is erect.
Meibomian gland dysfunction occurs when the glands on the edge of your eyelids (near your eyelashes) make insufficient or poor-quality oil. Tears containing less oil evaporate more quickly ...
However, all cicatricial alopecias involve inflammation directed at the upper part of the hair follicle where the stem cells and sebaceous gland (oil gland) are located. If the stem cells and sebaceous gland are destroyed, there is then no possibility for regeneration of the hair follicle, and permanent hair loss results.
Vaginal lubrication is a naturally produced fluid that lubricates the vagina. Vaginal lubrication production increases significantly during sexual arousal in anticipation of sexual intercourse. [1] Vaginal dryness is the condition in which this lubrication is insufficient, and sometimes artificial lubricants are used to augment it. Without ...
