The nervous system is the major controlling, regulatory and communicating system in the body. It is the center of all mental activity including thought, learning and memory.

Which answer choice BEST supports the idea that the nervous system is a type of communication system within the body?

• Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.

• Like other systems in the body, the nervous system is composed of organs, principally the brain, spinal cord, nerves and ganglia.

• These, in turn, consist of various tissues, including nerve, blood and connective tissue.

• Sensory input is converted into electrical signals called nerve impulses that are transmitted to the brain.

Multiple Choice

Millions of sensory receptors detect changes, called stimuli, which occur inside and outside the body. They monitor such things as temperature, light and sound from the external environment. Inside the body, the internal environment, receptors detect variations in pressure, pH, carbon dioxide concentration and the levels of various electrolytes. All of this gathered information is called sensory input.

Which word from the paragraph provides context clues to the meaning of the word "variations"?

• changes

• monitor

• external

• levels

Multiple Choice

What does the author use the word "integrated" to mean?

• antagonistic

• cohesive
