NEUR 1202 Lecture Notes - Lecture 4: Pineal Gland, Neuropeptide Y, Cell Group
Document Summary
The all have unique chemical structure which is what classifies them into different groups. Amino acids: glutamate (glu), y-aminobutyric acid (gaba) Chemicals released by one cell group that travels through the blood stream to act on target cells and effect it. Endocrine glands: made up of endocrine cells; these are the cells that release the hormones into the body. There are different types of endocrine glands: hypothalamus, pineal gland, pituitary gland (master gland), thyroid, adrenal glands, adrenal cortex, adrenal medulla, pancreas, gut, gonads. Even if you remove an important gland but put it back in a different spot it still secretes hormones like normal. Neural signaling: involves chemical released and diffusion across the synaptic cleft. Hormonal signaling: involves hormones being released into the bloodstream from the endocrine cells to act on target cells. When peptide or monoamine hormones bind to a receptor on the membrane the receptor changes shape.
