seedenäärmete

Seedenäärmete, also known as sebaceous glands, are microscopic exocrine glands found in the skin of most mammals. They are typically attached to hair follicles and secrete an oily or waxy substance called sebum. This sebum is composed of lipids, proteins, and cellular debris. The primary function of seedenäärmete is to lubricate and waterproof the skin and hair, preventing them from becoming dry and brittle. Sebum also plays a role in thermoregulation and provides a barrier against certain pathogens.

The activity of seedenäärmete is influenced by hormones, particularly androgens. During puberty, increased androgen levels lead to a surge in sebum production, which can contribute to conditions like acne. Seedenäärmete are distributed throughout the body, but they are most concentrated in areas with a high density of hair follicles, such as the scalp, face, and chest. While generally beneficial, excessive sebum production can lead to oily skin and hair, and can clog pores, contributing to acne formation. Conversely, insufficient sebum production can result in dry, itchy skin.
