What's the difference between acinus and gland?

Acinus


Definition:

  • (n.) One of the small grains or drupelets which make up some kinds of fruit, as the blackberry, raspberry, etc.
  • (n.) A grapestone.
  • (n.) One of the granular masses which constitute a racemose or compound gland, as the pancreas; also, one of the saccular recesses in the lobules of a racemose gland.

Example Sentences:

  • (20) During their voyage, they traverse the three acinus zones, and since in each they produce different enzymes, each zone represents a differentiation state of the advancing cell.

Gland


Definition:

  • (n.) An organ for secreting something to be used in, or eliminated from, the body; as, the sebaceous glands of the skin; the salivary glands of the mouth.
  • (n.) An organ or part which resembles a secreting, or true, gland, as the ductless, lymphatic, pineal, and pituitary glands, the functions of which are very imperfectly known.
  • (n.) A special organ of plants, usually minute and globular, which often secretes some kind of resinous, gummy, or aromatic product.
  • (n.) Any very small prominence.
  • (n.) The movable part of a stuffing box by which the packing is compressed; -- sometimes called a follower. See Illust. of Stuffing box, under Stuffing.
  • (n.) The crosspiece of a bayonet clutch.

Example Sentences:
