Sebaceous glands are important
components of the skin.
The skin is also known as the "integument", or "integumentary system".
Sebaceous glands are glands, i.e. groups of cells specialized for synthesizing and secreting specific fluids, that synthesize an oily substance called sebum - which is then released to the surface of the skin. These are exocrine glands (rather than endocrine glands) because they discharge sebum via ducts – as opposed to directly into the bloodstream.
To view the location of sebaceous glands relative to the other key components of the skin see the diagram of the structure of the skin. This may be of particular interest to students of courses in massage, reflexology, beauty therapies, and other health science or clinical courses.
