Exam 11: The Nervous System: Integration and Control

A neuron at rest has a charge difference across its cell membrane, with the interior of the cell negative relative to the exterior. This difference in charge across the plasma membrane is referred to as ________ potential.

The functional barrier between blood and the brain is cerebrospinal fluid.

Determine whether each of the following descriptions is characteristic of the parasympathetic division or the sympathetic division of the autonomic nervous system. Answers may be used more than once. -its effect results in a calm, relaxed state

Oligodendrocytes are similar to Schwann cells in that they

The left and right cerebral hemispheres are interconnected by a nerve tract network called the ________.

When an action potential arrives at the axonal bulb, ________ channels open in the presynaptic membrane, which causes neurotransmitter to be released into the synaptic cleft.

The ________ controls many functions in the body, including regulating body temperature and hunger drive.

Short-term memory is associated with the ________, whereas long-term memory is associated with the ________.

The nervous system is capable of using some neurotransmitters for more than one function. For example, some neurotransmitters may be excitatory in one pathway yet inhibitory in another. Discuss what accounts for the same neurotransmitter having different functions in alternate pathways.

Amyotrophic lateral sclerosis (ALS) is a demyelinating disease that results from nerve damage beginning in the

On your way to class, you decide to cross a busy street but fail to notice a fast-moving car coming toward you. When you do see the car, your heart rate and breathing increase, and you feel a burst of energy that helps you quickly move to the sidewalk. Describe how your nervous system was able to process the sight of the car with the need to move your legs.

The figure above shows a sagittal section through the brain. Match each labeled part (A through F) of the brain with its function. -receives sensory information from other parts of the body and relays it to proper areas of the cerebrum
