the salivary glands of the tongue [2] the liver; the lacrimal glands; the mammary glands; the pancreas [3] the bulbourethral (Cowper's) glands; The thyroid follicles can also be considered of acinar formation but in this case the follicles, being part of an endocrine gland, act as a hormonal deposit rather than to facilitate secretion.
The glands have an acinar structure (like a many-lobed berry), in which multiple glands branch off a central duct. The glands deposit sebum on the hairs and bring it to the skin surface along the hair shaft. The structure, consisting of hair, hair follicles, arrector pili muscles, and sebaceous glands, is an epidermal invagination known as a ...

These are the simple tubular, simple branched tubular, simple coiled tubular, simple acinar, and simple branched acinar glands. This image shows some of the various possible glandular arrangements. These are the compound tubular, compound acinar, and compound tubulo-acinar glands. Every gland is formed by an ingrowth from an epithelial surface ...
Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. [1] The duct portion may be branched (called compound) or unbranched (called simple). The glandular portion may be tubular or acinar, or may be a mix of the two (called tubuloacinar). If the glandular portion branches, then ...
A further complication in the case of the alveolar glands may occur in the form of still smaller saccular diverticuli growing out from the main sacculi. The term "racemose gland" [2] is used to describe a "compound alveolar gland" or "compound acinar gland." [3] Branched alveolar glands are classified as follows:
In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull hairs straight), sebaceous glands (secrete sebum onto hair follicle, which oils the hair), sweat glands (can secrete sweat with strong odour or with a faint odour (merocrine or eccrine ...
