The Central Nervous System is composed of
brain and spinal nerves
brain and spinal cord
cranial nerves and spinal nerves
sensory organs and spinal cord
Motor neurons of the somatic nervous system carry messages from the CNS
to skeletal muscle
to smooth muscle
to the brain
to glands that release hormones
Response of the parasympathetic nervous system
Stress and Distress
Fight or Flight
voluntary
Rest and Digest
Responses of the autonomic nervous system are
involuntary targeting smooth muscle and glands
voluntary targeting skeletal muscle
The structure that surrounds axons of neurons that increases the speed of an impulse is called
the myelin sheath
the neuroglial cells
the dendrite
the axon terminal
The space between a neuron and another neuron or an effector organ is called
Node of Ranvier
neural space
a longitudinal fissure
a synapse
What is released from an axon terminal?
myelin
neurotransmitters
hormones
electrical impulses
The fibers that receive messages and move them to the cell body of a neuron are
dendrites
axons
Schwan cells
Nodes of Ranvier
A neuron at rest is
stimulated
depolarized
polarized
When an axon is stimulated
sodium ions rush in making it depolarized
potassium ions rush in making it depolarized
sodium ion rush in making it polarized
potassium ions rush out making it repolarized
A nerve impulse that travels along a neuron is known as
fight or flight response
a stimulus
an action potential
sodium-potassium pump
When a neuron restores its resting potential, it is known as
polarization
depolarization
repolarization
After an action potential has traveled down an axon, the ion balance of sodium and potassium ions is restored by
a sodium-potassium pump
depolarization
repolarization
Reorder the following steps of a nerve impulse.
Neuron is polarized and at rest.
A stimulus changes the permeability of the neuron and depolarization occurs.
The action potential travels like a wave towards the axon terminal.
Repolarization of the neuron occurs.
Ionic balance is restored by the sodium-potassium pump.
A rapid, predictable response from the spinal cord to a stimulus is called
an action potential
a reflex
a synapse
a parasympathetic response
A bundle of nerve fibers is called a _____. It is surrounded by the _____.
fascicle; perineurium
fascicle; epineurium
neuron; endoneurium
nerve; endoneurium
Maintaining homeostasis is a major job of the
cerebral spinal fluid
cerebellum
cerebral cortex
hypothalamus
Which of the following does not protect the brain?
vertebrae
skull
cerebospinal fluid
meninges
What does the vagus nerve do?
regulates heart rate
regulates breathing
stimulates digestion
All of these are jobs of the vagus nerve
Capillaries in the brain are not permeable to many substances. This is known as
a brain synapse
the blood brain barrier
an all or nothing response
meningitis
The sympathetic nervous system is operating when a person is
resting
under stress
sad
happy and content
An autoimmune disease in which the body attacks the myelin sheaths around neurons is called
menegitis
Multiple sclerosis
Alzheimer's disease
Parkinson's disease
When brain cells die because of lack of oxygen, it is called
a stroke
paralysis
a concussion
The inflammation of protective connective tissue of the brain and spinal cord is called
brain trauma
a concussion
Multiple sclerosis
menengitis
