Overall, the phonetic transcription for "Sebaceous glands" would be /sɪˈbeɪʃəs ɡlændz/.

Sebaceous glands are small, oil-producing glands found in the skin of mammals, including humans. These glands are responsible for the production and secretion of sebum, an oily substance that lubricates and waterproofs the skin and hair.
Sebaceous glands are typically connected to hair follicles, with their ducts opening directly onto the skin's surface. However, they can also exist as independent glands, especially in areas without hair follicles, such as the eyelids and genitalia. The number and distribution of sebaceous glands vary among individuals, but they are more concentrated on the face, scalp, chest, and back.
The main function of sebaceous glands is to keep the skin moisturized and prevent it from drying out. Sebum, the waxy and oily substance secreted by these glands, helps to create a protective barrier by trapping moisture and preventing excessive evaporation from the skin's surface. Sebum also helps to keep the skin soft and supple, acting as a natural moisturizer.
However, when sebaceous glands produce an excess amount of sebum, it can lead to oily skin and contribute to conditions like acne. On the other hand, underactive sebaceous glands can result in dry and flaky skin.
Overall, sebaceous glands play a crucial role in maintaining the health and integrity of the skin by regulating its moisture levels and providing natural protection against environmental factors.
The word "sebaceous" originates from the Latin word "sebum", which means "fat" or "grease". The term "sebaceous glands" refers to the small, oil-producing glands found in the skin. These glands are responsible for secreting sebum, an oily substance that helps lubricate and protect the skin and hair.
