Endocrine System
Cards in this deck (9)
- 1Mechanisms for cell communications- Gap Junction
- NeuroTransmitters
- Paracrine (local) hormones
- Hormones - 2Gap JunctionPores in cell membrane allow signaling chemicals to move from cell to cell
- 3Define HormoneHormones are chemical messengers that are secreted into bloodstream, stimulating response in other tissues and organs
- 4Organs of Endocrine System- hypothalamus
- pituitary gland
- thyroid
- parathyroids
- adrenal glands
- pineal body
- reproductive glands (which include the ovaries and testes)
- pancreas - 5Endocrine Glands- Ductless glands
- Release hormones into tissue fluids
- has dense capillary networks to distribute hormones
- intracellular effects
- alter target cell metabolism - 6Exocrine Glands- Carry secretion to body surface or other organ cavity
- Extracellular effects ( Food Digestion) - 7Nervous System- Electrical impulses and neurotransmitters, adapts quickly to continual stimulation
- reacts quickly (1 -10 msec), stops quickly
- Local, specific effects on target organs - 8Endocrine Systems- Hormones in blood, adapts slowly ( days to weeks)
- Reacts slowly (seconds-days), can continue after stimulus stops
- General, widespread effects on many organs - 9Hypothalamus communicates- Connected to the pituitary gland by a complex of blood vessels called the hypothalmo-hypophyseal portal
