4 special functions of nerve cells
|
1.recieve info
2.produce an appropriate output signal 3.send signal to terminal ending 4.transmit signal to other nerve cells, glands, muscles |
|
cell body
|
1.recieves and sends nerve impulses
2.contains nucleus 3.makes proteins 4.uses energy for maintenance and growth |
|
nucleus
|
contains all information needed to maintain the cell
|
|
dendrites
|
1.recieves signals
2.sends electrical signal to cell body 3.respond to specific stimuli (sound, pressure,temp) 4.dendrites of brain respond to neurotransmitters |
|
myelin sheath
|
1.whittish, fatty layer that insulates nerve fiber
2.speeds up nerve impulses |
|
axon
|
1.carrys impulses away
2.can make contact with up to 1000 other neurons 3.length = mm to 1 meter |
|
synaptic terminals
|
1.end of axon
2.containt neurotransmitter 3.communicate wiht gland, muscle, second nuron |
|
synapse
|
1.space between nerve cells
2.where communication happens 3.neurotransmitters are released 4.pre-synaptic vs. post |
|
neurotransmitters
|
1.chems released from synaptic terminals
2.bind to receptors and make electrical charge 3.influence mood, sex drive, appettite, movement 4.serotonin, epinepherine |
