Microglia
Form scars and the supporting network in the brain
Oligodendrocytes
Remove cellular debris
Schwann cells
Form myelin sheaths around axons in the CNS
Ependymal cells

What are the functions of neurons?
Physical and chemical support to other cells
Communication within the nervous system
Communication from the brain to the body
Communication from the external world to the body and brain
What are the functions of the main parts of a neuron?
Axon
Sends signals out

Receive signals
Dendrites
Metabolic center
What are the components of the CNS?
Cerebrum
Basal Ganglia
Somatic Nervous System
Autonomic Nervous System
Diancephalon

Dorsal root ganglion are an example of what type of neuron?
Bipolar
Pseudounipolar
Multipolar
Unipolar
Multipolar neurons are
Sensory
Special senses
Motor
Match the mechanism to the correct neuroimaging technique.
FMRI
Measures small changes in blood flow during brain activity
DTI
Magnetic fields are utilized to show detailed images
PET
Radioactive substance is used as a tracker. More absorption shows more chemical activity.
MRI
Use of x-rays and computers to produce multiple images from a variety of angles
CT
Measures how water diffuses around bundles of axons
Label the parts of the neuron.
A
Node of Ranvier
D
Myelin
B
Axon terminal
E
Cell body/Soma
C
Axon hillock
F
Dendrite
Match the correct function with each part of a neuron.
Synapse
Metabolic center of the cell
Axon hillock
Bring impulses toward cell body
Node of Ranvier
Cone the connects soma and axon
Axon
Insulation that allows impulses to move more efficiently
Dendrite
Junction between nerves
Axon terminals
Takes impulses away from the cell body
Myelin
Allow quick generation of electrical impulses along the axon
Soma
Releases neurotransmitters that relay signals across the synapse
Select all that describe white matter of the brain.
Axons covered in myelin
Provides method for communciation
Contains cell bodies
Where processing occurs
Includes tracks and funiculus
What is responsible for balance, coordination of movements (including eye movements), motor learning, muscle memory, thinking, and emotions?
Brain Stem
PNS
Temporal lobe
Cerebellum
What is responsible for breathing, consciousness, BP, HR, and sleep?
Brain Stem
PNS
Temporal lobe
Cerebellum
Gyri and sulci exist to create greater surface area in the brain.
