epithelium |
what germ layers are glands derived from |
|
merocrine |
gland cell product released by exocytosis found in sweat glands usually secretes protein |
|
apocrine |
Cytoplasm is lost with gland cell product found in stinky sweat glands |
|
Holocrine |
Cell ruptures and the gland cell product is released with the rest of the cell contents found in sebaceous glands |

|
parenchyma |
the epithelial derived, functional part of the gland comprising the duct and secretory unit |
|
Stroma |
capsule of the gland |
