GLANDS Flashcards
What are glands composed of?
Epithelial cells
How are glands formed?
Form by the growth of epithelial cells into underlying connective tissue
What are exocrine glands?
Release secretions through ducts onto epithelial surfaces
What are endocrine glands?
Lack ducts and secrete hormones into the blood
What happens to secretory cells in the exocrine gland?
Secretory cells remain connected to surface by a duct
What happens to the connecting cells in the endocrine ducts?
Connecting cells disappear (duct is removed)
What happens to secretions in the endocrine ducts?
Secretions released into blood vessels
Where is merocrine found?
In sweat glands, move water and release heat
What is merocrine considered as?
Normal exocytosis
Where is apocrine found?
In mammary glands and sweat glands in axial/groin
What does apocrine have?
Same transcription and translation
What is apocrine considered as?
Apical surface pinched off
Where is holocrine found?
Salacious glands and thick oil secretion (sebum) - maintain moisture
What does holocrine do?
Creates daughter cells
What is holocrine considered as?
Entire cell released
