The division of the nervous system that carries signals from nerve endings to the central nervous system is the:
sensory (afferent) division.
motor (efferent) division.
sympathetic division.
parasympathetic division.
The part of the nervous system that carries signals from the skin, bones, joints, and muscles to the central nervous system is the:
autonomic motor.
somatic motor.
visceral sensory.
somatic sensory.
The central nervous system includes the:
somatic motor system.

When you touch something hot, the type of neurons that send impulses allowing you to withdraw your hand are:
afferent neurons.
efferent neurons.
interneurons.
neuroglia.
The purpose of the sympathetic nervous system is:
to relay information from the somato-sensory system to the thalamus in the brain.
to relay sensations from the skin and the extremities to the brain.
to calm the body and promote a 'rest and digest' state which is essential for energy conservation and maintaining basic bodily functions.
to prepare the body for a 'fight or flight' response in stressful situations by rapidly increasing heart rate, blood pressure, and alertness.
The purpose of the parasympathetic nervous system is:
to relay information from the somato-sensory system to the thalamus in the brain.
to relay sensations from the skin and the extremities to the brain.
to calm the body and promote a 'rest and digest' state which is essential for energy conservation and maintaining basic bodily functions.
to prepare the body for a 'fight or flight' response in stressful situations by rapidly increasing heart rate, blood pressure, and alertness.
When a neuron's cell membrane is polarized and contains an abundance of sodium on the inside and an abundance of potassium on the outside, the cell is:
in resting potential, waiting to react if a stimulus comes along.
in the process of depolarizing.
in the process of conducting an action potential down the axon.
unable to react to a new stimulus.
What is the purpose of myelin?
To facilitate the free movement of ions across the cell membrane.
To provide an insulating layer around nerves, which allows electrical impulses to transmit rapidly and efficiently.
To slow down the rapid electrical impulses arriving at the brain so that those signals can be processed and moved to the correct parts of the brain.
To increase the sensitivity of temperature and pressure receptors in the skin.
What are the parts of the Central Nervous System?
The brain and spinal cord.
All sensory and motor neurons.
The sympathetic and parasympathetic nervous systems.

White matter appears white because of
its lack of myelin.
its abundance of myelin.
a preponderance of neuron cell bodies.
the presence of the meninges.
Descending (efferent) spinal tracts carry
sensory signals up the spinal cord to the brain.
sensory signals down the spinal cord to the body.
motor impulses up the spinal cord to the brain.
motor impulses down the spinal cord to skeletal muscles.
A patient is admitted to the hospital with paralysis on the right side of the body. Magnetic resonance imaging reveals that he has suffered a stroke on the left side of his brain. What is the most likely explanation for the location of his symptoms?
A stroke on the left side of the brain would affect corticospinal tracts responsible for movement.
A stroke on the left side of the brain would affect motor signals being sent to the right side of the body.
A stroke on the left side of the brain would affect the area responsible for movement.
There is no logical explanation because a stroke on the left side of the brain would affect movement on the left side of the body.
