Nervous System Worksheet

The basic building blocks of the nervous system are

• neurons

• medullas

• pons

• rods

The two main divisions of the central nervous system are the

• right and left hemispheres.

• brain and the spinal cord.

• somatic and autonomic nervous systems.

The part of the reticular activating system that helps regulate sleep and alertness is the

• medulla

• cerebellum

• pons

The outer layer of the brain is called the

• corpus callosum.

• cerebral cortex

• cerebellum

• forebrain

The corpus callosum is responsible for

• regulating body temperature.

• storing nutrients.

• moving information from one hemisphere of the brain to the other.

Damage to Broca's area and Wernicke's area of the brain can cause

• short-term memory loss.

• loss of hearing.

• difficulties in producing and understanding speech.

Electroencephalograms (EEG) have been used by researchers to

• measure stages of sleep and diagnose some disorders.

• identify specific areas of the brain that are associated with certain sensations.

• generate a three-dimensional image of the brain.

Signal-detection theory attempts to find out

• how psychological factors affect perception.

• the lowest sounds that people and animals can hear.

• which cues are the most effective for showing depth.

Rods in the retina allow us to detect

• colors

• black, white, and gray

• the depth, or distance, of objects

• objects nearby

Sounds are caused by

• the release of sensory neurons.

• electromagnetic energy.

• vibrations of the hair cells
