Gland practice:
Identify the structural class of each gland described here:
1. Flask-shaped gland, unbranched ducts
2. Slender, straight gland, unbranched ducts
3. Combination of gland shapes
Most exocrine glands are apocrine, which means they release secretions by exocytosis.
Holocrine glands store secretions until the cells rupture. Ruptured cells are replaced through mitosis.
Sweat glands are an example of holocrine glands.
The mammary gland is the most likely example of an apocrine gland.
