22
Q

cerebrum

A

largest portion of the brain

23
Q

A

tough body, the bundle of nerve fibers that connect the right and left hemispheres of the cerebrum

24
Q

cortex

A

outer shell, outer layer of nervous tissue in the brain

25
Q

dura mater

A

tough matter, thick fibrous outer membrane covering the brain

Q

efferent

A

to carry out or take away from a place

27
Q

ganglia

A

cell bodies in the peripheral nervous system that cluster together in groups

28
Q

geriatric

A

pertaining to old age or the aging process

29
Q

gyrus

A

convolution or raised area between grooves

30
Q

hypothalamus

A

part of the brain that links the endocrine system to the nervous system

31
Q

impulse

A

electrical signal that travels along an axon

32
Q

kyphosis

A

abnormal convex curvature of the spine

33
Q

myeling

A

fatty white substance that surrounds some axons and is produced by special cells in the central nervous system

34
Q

pia mater

A

delicate soft matter, thin innermost membrane covering the brain

35
Q

pituitary

A

master endocrine gland that affects nearly all hormonal activity in the body

36
Q

potential space

A

space or cavity that can exist between two adjacent body parts that are not tightly adjoined does not appear during normal functioning

37
Q

sulcus

A

groove

38
Q

synapse

A

junction across which a nerve impulse passes from an axon to another neuron, muscle cell or gland cell

39
Q

syrinx

A

pathological tube shaped lesion in the brain or spinall cord

40
Q

thalamus

A

part if the brain that relays sensory impulses to the cerebral cortex

41
Q

central nervous system

A

made up of the brain and spinal cord, lies in the dorsal cavity of the body

42
Q

perikaryon

A

cell body, contains nucleus

43
Q

dendrites

A

short branching fibers extend from the cell body, collect electric signals and setup an electrical impulse that will pass through thee neurons to the next neuron

44
Q

glial cells

A

supply nutrition and provide support for the neurons

45
Q

oligodendrocyte

A

secrete fatty substance surrounds axon in a sheath like insulator, allows electrical signal to travel more quickly

46
Q

astrocytes

A

help form a blood-brain barrier

47
Q

A

macrophages of the CNS, destroy pathogens and get rid of dead neurons

48
Q

diencephalon

A

thalamus, hypothalamus, pituitary gland

49
Q

brainstem

A

medulla oblongata, pons, midbrain
