Hypothalamus acts with pituitary glad to release other hormones. Parathyroid gland works to regulate calcium levels with bones and kidneys. Pth part of regulatory control as well as calcitonin. Shuttling fuel to high priority organs in times of need. Many play a roll in reserving calcium and for excretion (also regulate blood glucose at the level of kidney) and leptin that regulates adipose tissue in body. Exchange of ions and molecules b/w adjacent cells, of the same type, across gap junctions. Chemical signals (paracrine factors) transferring info from cell to cell within single tissue. Release hormones into bloodstream to travel to target cell or organ. Alters metabolic activities of tissues and organs simultaneously. Neurons release neurotransmitters through synapses directly to a target cell with appropriate receptors to form action potentials.
