Q

blood-brain barrier

A

the separation of brain nervous tissue from capillaries with the brain tissue

21
Q

cerebellum

A

little brain, second largest portion of the brain

22
Q

cerebrum

A

largest portion of the brain

23
Q

corpus callosum

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
dura mater
tough matter, thick fibrous outer membrane covering the brain
26
efferent
to carry out or take away from a place
27
ganglia
cell bodies in the peripheral nervous system that cluster together in groups
28
geriatric
pertaining to old age or the aging process
29
gyrus
convolution or raised area between grooves
30
hypothalamus
part of the brain that links the endocrine system to the nervous system
31
impulse
electrical signal that travels along an axon
32
kyphosis
abnormal convex curvature of the spine
33
myeling
fatty white substance that surrounds some axons and is produced by special cells in the central nervous system
34
pia mater
delicate soft matter, thin innermost membrane covering the brain
35
pituitary
master endocrine gland that affects nearly all hormonal activity in the body
36
potential space
space or cavity that can exist between two adjacent body parts that are not tightly adjoined does not appear during normal functioning
37
sulcus
groove
38
synapse
junction across which a nerve impulse passes from an axon to another neuron, muscle cell or gland cell
39
syrinx
pathological tube shaped lesion in the brain or spinall cord
40
thalamus
part if the brain that relays sensory impulses to the cerebral cortex
41
central nervous system
made up of the brain and spinal cord, lies in the dorsal cavity of the body
42
perikaryon
cell body, contains nucleus
43
dendrites
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
glial cells
supply nutrition and provide support for the neurons
45
oligodendrocyte
secrete fatty substance surrounds axon in a sheath like insulator, allows electrical signal to travel more quickly
46
astrocytes
help form a blood-brain barrier
47
microglial cells
macrophages of the CNS, destroy pathogens and get rid of dead neurons
48
diencephalon
thalamus, hypothalamus, pituitary gland
49
brainstem
medulla oblongata, pons, midbrain
