16
Q

dendrites

A

a short branched extension of a nerve cell

17
Q

axons

A

the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells

18
Q

axon hillock

A

specialized part of the cell body of a neuron that connects to the axon

19
Q

axon terminals

A

use electrochemical signals and neurotransmitter chemicals to transmit impulses from one neuron to the next, axon terminals are separated from neighboring neurons by a small gap called a synapse

20
Q

myelin

A

Myelin is a fatty white substance that surrounds the axon of some nerve cells

21
Q

nodes of Ranvier

A

The action potential travels from one location in the cell to another, but ion flow across the membrane occurs only at the nodes of Ranvier

22
Q

depolarization

A

loss of polarization

23
Q

action potential

A

occurs when the membrane potential of a specific axon location rapidly rises and falls

24
Q

repolarization

A

refers to the change in membrane potential that returns it to a negative value

25
Q

cerebrum

A

the principal and most anterior part of the brain in vertebrates

26
Q

parietal lobe

A

integrates sensory information among various modalities

27
Q

frontal lobe

A

part of the brain that controls important cognitive skills in humans

28
Q

occipital lobe

A

visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex

29
Q

temporal lobe

A

Processing sensory input. Auditory. Adjacent areas in the superior, posterior

30
Q

gray matter

A

darker tissue of the brain and spinal cord, consisting mainly of nerve cell bodies and branching dendrites.

31
Q

cerebral white matter

A

connect various gray matter areas of the brain to each other, and carry nerve impulses between neurons.

32
Q

cerebellum

A

the part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity
