Answer to Question 1

Traumatic brain injury (TBI) is a major cause of death in individuals under 24 years old. Deaths related to transportation (e.g., automobiles, motorcycles, and bicycles) surpass all other causes of TBI (e.g., falls, assaults, sports, and firearms). Deaths due to automobile accidents have been reduced by almost 50 because drivers and passengers are now using seatbelts and lapbelts. However, driving when drinking alcohol decreases the use of seatbelts and thus increases deaths due to accidents. TBI caused by motorcycle accidents has been reduced between 20 and 50 by requiring riders to use helmets and up to 85 for bicycle riders.

Answer to Question 2

The two divisions of the nervous system are the anatomical division and the functional divisions.

The anatomical division is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system includes the cerebrum, cerebellum, brainstem, spinal cord, thalamus, subthalamus, and basal ganglia. The peripheral nervous system includes the spinal nerves, cranial nerves, and sensors.

The functional divisions of the nervous system are composed of the autonomic nervous system (ANS) and the somatic nervous system. The autonomic nervous system (involuntary component) includes the sympathetic nervous system and the parasympathetic nervous system. The somatic nervous system is the voluntary component of the nervous system.
