holocrine gland

Sebaceous holocrine glands can be found in both lips.

Holocrine glands - the entire cell disintegrates to excrete its substance; for example, sebaceous glands of the skin and nose.

Holocrine glands - the entire cell disintegrates to secrete its substances (e.g., sebaceous glands)

Examples of holocrine glands include the sebaceous glands of the skin and the meibomian glands of the eyelid.

The sebaceous gland is an example of a holocrine gland because its product of secretion (sebum) is released with remnants of dead cells.

Exocrine glands are named apocrine glands, holocrine glands, or merocrine glands based on how their products are excreted.

In the glands, sebum is produced within specialized cells and is released as these cells burst; sebaceous glands are thus classified as holocrine glands.

It is a holocrine gland enclosed in a connective tissue capsule made up of glandular acini that deposit their oil secretion into a common collector tube ending in a variable number of pores (openings), most usually two.
