Question 11

The peripheral nervous system is divided into two parts. Describe the differences between these two parts.

Question 12

Describe the functions of the nervous system.

Question 13

Bony coverings protect both the brain and the spinal cord. List the three membranes (meninges) that provide additional protection.

Question 14

The largest part of the brain is the cerebrum and it is covered with a thin outer layer of gray matter called the cortex. What are the three specialized areas of the cortex and their major areas of function?

Question 15

Each hemisphere of the cerebrum is divided into lobes that contain areas related to specific functions. Discuss the different lobes and their specific functions.

Question 16

Several parts of the cerebrum are involved in the language function. Describe the responsibilities of the Wernicke's and Broca's areas.

Bony coverings called vertebrae surround the spinal cord and protect it. Discuss the components of the vertebral column.

Question 18

Nerves control both voluntary and involuntary functions in the body. Describe the two types of nerves that control these functions.

Question 19

The autonomic nervous system is divided into two subsystems: sympathetic nervous system and parasympathetic nervous system. Describe the differences between these two systems.

Question 20

The brain requires both oxygen and nourishment in the form of glucose in order to function and to survive. Discuss how glucose is transported to the brain.
