Exam 20: Central Nervous System

The outermost protective covering of the brain is the dura mater.

The term used to describe all of the connections within the human cortex to the rest of the brain is connectomes.

What part of the brain can produce a hormone?

The fourth ventricle in the brain is an expansion of the central canal of the spinal cord.

Explain how the cerebrum and cerebellum are similar to a negative-feedback mechanism in terms of controlling the movement of skeletal muscles.

As you move from the spinal cord up the central nervous system, the:

Most of the motor tracts of the central nervous system do not decussate.

Cerebrospinal fluid circulates in the subarachnoid space of the meninges.

The foramen magnum is the structure that divides the:

The diencephalon consists of the thalamus and the hypothalamus.

Explain the location and function of primary, secondary, and tertiary sensory neurons. Which of these neurons can decussate?

The layer of the meninges that serves as the inner periosteum of the cranial bone is the:

The part of the brain that can directly influence or inhibit the release of hormones from the pituitary is the:

Axons from the gray horns of the spinal cord terminate in:

Repetition of nerve impulses on the same neuron circuitry produces memory.

A lesion in the cerebral cortex might result in:

The two "colorful" structures in the brain, the red nucleus and the substantia nigra, are located in the midbrain.

Kathryn suffered a cerebrovascular accident. It was determined that the left side of her cerebrum was damaged. On which side of her body will she most likely notice paralysis? Explain why.

The structure in the brain called the olive is found in the midbrain of the brainstem.

The deeper, wider groove on the spinal cord can be used to identify the ventral side of the spinal cord.
