50
Q

serve to transmit and broadcast inofrmation

A

neurons or nerve cells

51
Q

communicate information through nerve impulses form the brain to the rest of the body or viceversa

A

neurons or nerve cells

52
Q

perform functions of support nutirtion and defense of nervous tissue

A

glial cells and neuroglia

53
Q

23 main glial cells or neuroglia

A

astrocytes cells, oligodendrocytes and schwann cells

54
Q

branched parts of the neuron that receive information nerve impulses and transport it to the cell body

A

dentrites

55
Q

is the central part of the neuron, nucleus of the cell

A

soma, cell obdy or perikaryon

56
Q

is the ranch that starts form the cell body and communicates the info to another neuron. different extension

A

axon

57
Q

white, fatty substance, 90 times per second

A

myelin sheath

58
Q

is the small brown in the axon

A

schwann cell

59
Q

the last part of the neuron

A

nerve ending

60
Q

the 4 types of neurons

A

sensory neurons, motor neurons, interneurons and relay

61
Q

receive a stimulus by the 5 senses passing the organs, brain and to the spianl cord

A

sensory neurons

62
Q

emit signals form the cns to make a movemnt

A

motor neurons

63
Q

transmit the info between sensory and motor

A

interneurons

64
Q

large neurons that transmit a info by the cns to another without the pns

A

relay

65
Q

when two neurons repeated infinitely, in the terminal axon

A

synapse

66
Q

the small space between it and next neuron

A

sypnatic

67
Q

a particle is released in the synapse from the axon of the neuron that emits the information

A

neurotransmitters

68
Q

their axons are thicker and the nerve impulse propagates faster thanks to saltatory conduction

A

myelinated neurons

69
Q

they grow myelin and the conduction is slowly

A

unmyelinated neurons

70
Q

2 types of neurons

A

myelinated and unmyelinated

71
Q

the nerve impulse is transmitted along a neuron through a process of:

A

depolarization, sodium potassium pump

72
Q

who the nerve impulse propagates faster in axons?

A

with myelin

73
Q

what is myelin

A

is an electrical insulators, it does not follow charges to pass throgth it

74
Q

In myelinated neurons, the process of saving energy occurs only in?

A

ranvier´s nodes

75
Q

chemical created by the body that transmit signals

A

neurotransmitter

76
Q

neurotransmitter synthesized form tryptophan, happines homrmones and group of indolamines

A

serotonin

77
Q

neurotransmitter invovled in addictive behaviurs and in the cause of pleasant sensations, muscular movements, cognitive process, learning decision

A

dopamine

78

A

glutamate

81
Q

inhibitory messenger stop action of excitatory neurotransmitters contributes control, anxiety, and does not cross the body’s blood-brain barrier, so ti must be synthesized in the brain

A
