Match each landmark of the brain with its description or location. -Groove that separates the occipital and parietal lobes

If the ventral nerve root of a spinal nerve were destroyed, a person would lose _____ related to that pathway.

The geniculate bodies are important nuclei in the hypothalamus.

For voluntary skeletal muscle activity, impulses originate in the cerebrum but coordination of the activity is a function of the cerebellum.

Poliomyelitis results in flaccid paralysis via destruction of posterior horn neurons.

The secondary motor area activates groups of muscles rather than individual muscles.

Describe the four types of brain waves characterized by frequency and amplitude of the waves.

The pyramids are formed in the:

The tentorium cerebelli is a sickle-shaped extension of the dura that separates the two hemispheres of the cerebellum.

Jeffery contracted bulbar poliomyelitis, and it has affected the medulla oblongata. The doctors warned the family that his condition is grave and death may be imminent. What function of the medulla oblongata has warranted such a dire prognosis?

The adult brain weighs about 3 pounds.

Secondary sensory neurons conduct impulses from the spinal cord or brainstem to the:

Under normal brain functioning, activation of the reticular activating system (RAS) produces consciousness.

A lesion or tumor in the hypothalamus may cause overeating and result in substantial weight gain.

Both the inferior colliculi and superior colliculi are found in the midbrain.

Based on the system of naming tracts in the spinal cord, the spinocerebellar tract would be an ascending tract.

All spinal nerves are mixed nerves.

The dorsal nerve root carries motor impulses from the spinal cord to the skeletal muscles.

If the dorsal root ganglia of the spinal nerve were destroyed, a person would lose _____ related to that pathway.
