Endocrine System Histology Flashcards
Endocrine glands
Glands of the endocrine system that secrete hormones directly into the blood rather than through a duct
Exocrine glands
Secrete substances into a lumen/duct or onto a surface
Peptide hormone
Insulin,Prolactin
Receptors at the cell surface
Steroid hormones
Estradiol Testosterone need carrier proteins for transport
Nuclear receptors
What type of gland
Endocrine
What type of gland
exocrine
Ductless gland
Uses blood vessels to transport information for signaling
