What is the central nervous system (CNS) made of?

• brain and spinal cord
• brain and cranial nerves
• spinal cord and spinal nerves
• cranial nerves and spinal nerves

What is the peripheral nervous system (PNS) made of?

• brain and spinal cord

• cranial nerves and spinal nerves

Somatic nervous system controls ___________, whereas the autonomic nervous system controls ___________.

• skeletal muscles; visceral organs

• brain and spinal cord; spinal and cranial nerves

• visceral organs; skeletal muscles

• spinal and cranial nerves; brain and spinal cord

The nervous system

• detects changes in the internal or external environment

• integrates information from several sources and uses it to determine an appropriate response.

• controls the movement of muscles.

• all of the above.

Spinal and cranial nerves make up the:

• CNS

• PNS

• ANS

Spinal nerves

• carry messages from the brain to the brain

• carry messages from the spinal cord to

• carry impulses to and from the spinal cord

Carry impulses to and from the brain

• spinal nerves

• cranial nerves

Carry information from the skin, skeletal muscles, and joints

• somatic sensory fibers

• visceral sensory

• motor nerve fibers

Fibers carry information from visceral organs

• visceral sensory

• somatic sensory

• motor
