Exam 7: The Nervous System

The collection of spinal nerves at the inferior end of the spinal cord is called the cauda equina.

The parasympathetic division is also called the craniosacral division since the preganglionic neurons originate in the brain and sacral region of the spinal cord.

Cell bodies of the sensory neurons of the spinal nerves are located in ________.

Match the following: -Thalamus, hypothalamus, and epithalamus

The delicate innermost membrane, or meningeal layer, that clings to the surface of the brain and spinal cord is known as the ________ mater.

Which of the following is NOT a major nerve of the brachial nerve plexus?

Match the following: -Functional nervous system division that carries information from the central nervous system toward effectors

An action potential is caused by an influx of these ions into the cell ________.

Neurons with several processes branching off the cell body, such as motor neurons and interneurons (association neurons), are structurally classified as ________.

Which cranial nerve descends into the thoracic and abdominal cavities to regulate heart rate and promote digestive activity?

The hypothalamus is the "emotional-visceral" center of the brain and, thus, is an important part of the ________.

Gaps between adjacent Schwann cells of a myelin sheath are known as nodes of Ranvier.

The only pair of cranial nerves to extend to the thoracic and abdominal cavities is the ________ nerves.

Cerebrospinal fluid circulates through all of the following EXCEPT ________.

Match the following: -Contains centers that control heart rate, blood pressure, breathing, swallowing, and vomiting

The primary somatic sensory cortex is located in the ________ lobe of the cerebrum.

Which of the following effects is characteristic of the parasympathetic nervous system?

The parasympathetic and sympathetic nervous systems are subdivisions of the autonomic nervous system.

Hemiplegia and aphasia characterize those patients who have experienced a ________.

Using Figure 7.1, identify the following: -The gaps between Schwann cells are indicated by ________.
