Nervous System Test Review

Nervous System Functions

100

What is the correct order of the 3 main functions of the nervous system? 

sensory input--integration--motor output

200

What is it called when sensory receptors gather information and send it to the brain? 

sensory input

300

What occurs when muscles or glands respond to signals from the brain? 

motor output

400

The system responsible for integration and includes the brain and spinal cord

CNS

500

The division that delivers messages from sensory organs to the brain

afferent division

Neurons Stx and Class

100

Neurons are classified structurally by what? 

the number of projections extending from the soma

200

This is the most common structural neuron type in the human body

multipolar

300

this neuron type has one axon and one dendrite extending from the soma

bipolar 

400

this structural neuron type is common in the PNS and includes most sensory neurons

unipolar 

500

This structural type is extremely rare and found only in special sense organs? 

bipolar 

Functional Neurons

100

What is another name for sensory neurons? 

afferent neurons 

200

These neurons carry impulses away from the CNS to muscles and glands

efferent/motor neurons 

300

Another term for interneurons? **

association neurons 

400

These are the most numerous neurons in the body

interneurons 

500

This is the approximate number of neurons in the human body? 

100 billion 

Neuroglial Cells

100

The primary job of glial cells

supporting and filling spaces between neurons 

200

the term glial means what

glue

300

the largest type of glial cell

astrocytes 

400

the glial cell forms the myelin sheath in the CNS

oligodendrocyte

500

this glial cell forms myelin in the PNS

Schwann cells 

Divisions of the NS

100

This division includes the brain and spinal cord

CNS

200

This division includes all nerves extending from the brain and spinal cord? 

PNS

300

also known as the efferent division

motor division 

400

this division activates the body during stress

sympathetic division 

500

stimulates "rest and digest" 

parasympathetic 

Neuron Anatomy

100

the long projection that carries impulses away from the soma

axon

200

the structure also known as the cell body

soma

300

short branches that receive impulses

dendrites 

400

This lipid layer speeds up action potentials

myelin sheath

500

gaps in the myelin that allow impulses to jump 

nodes of ranvier 

Brain Anatomy

100

this structure allows muscle coordination and muscle memory

cerebellum

200

this connects left and right hemispheres

corpus callosum 

300

The largest and outermost part of the brain

cerebrum

400

This meets basic survival needs like breathing and heart rate maintenance

brain stem 

500

This structure is also knows as the interbrain

diencephalon

Brain Lobes and Stx

100

This lobe controls executive function and decision making 

frontal lobe

200

this lobe processes visual information

occipital 

300

this lobe processes smell and hearing 

temporal 

400

this area allows you to understand speech

Wernicke's area

500

this area allows you to produce speech

Broca's area 

Brain Structures

100

This controls heart rate and breathing

medulla oblongata

200

controls other hormone-releasing glands

pituitary gland 

300

maintains homeostasis and controls the pituitary gland

hypothalmus

400

sorts sensory data and sends it to the cerebrum

thalamus 

500

acts as a bridge between cerebellum and cortes

pons
