Anatomy- Chapter 7: The Nervous System

When the nervous system processes and interprets sensory input and decides what should be done, this is known as:

• integration

• motor output

• stimuli

• sensory processing

What are the two structural subdivisions of the nervous system? (select both)

• central nervous system

• peripheral nervous system

• autonomic nervous system

• sympathetic nervous system

The _________ consists of the brain and the spinal cord.

• central nervous system

• peripheral nervous system

• autonomic nervous system

• sympathetic nervous system

Cranial nerves carry impulses to and from the ________.

• brain

• spinal cord

• vertebral column

• heart

Sensory fibers delivering impulses from the skin, skeletal muscles, and joints are called:

• somatic sensory fibers

• visceral sensory fibers

• autonomic sensory fibers

• parasympathetic sensory fibers

The _________ nervous system regulates events that are automatic, or involuntary.

• autonomic

• somatic

• central

• motor

Which of the following is NOT an example of a function of the autonomic nervous system?

• activity of smooth muscle

• activity of cardiac muscle

• conscious control of skeletal muscle

• all of the above are correct

Nerve glue:

• Neuroglia

• Neurons

• Myelin sheath

• Motor neurons

Star-shaped cells that make up nearly half of the neural tissue; they help protect the neurons from harmful substances that might be in the blood.

• Astrocytes

• Microglia

• Ependymal cells

• Oligodendrocytes

Neuroglia that wrap their flat extensions tightly around the nerve fibers, producing fatty insulating coverings called myelin sheaths.

• Oligodendrocytes

• Ependymal cells

• Astrocytes

• Microglia
