Sample Question 1
What is the major function of the nervous system?

Ther servous system is a very fast communication system that responds to out boilogical needs in the micro-to-millisecond range: 1. Gather information (sensation) 2. Analyse and interpret - (aware or unaware) 3. Respond (behave)

The nervous system is responsible for producing hormones

The nervous system primarily regulates body temperature

The nervous system functions to help with digestion

Sample Question 2
What are the different types of nerves?

Cranial (related to the brain)

Sensory (outside to the brain = afferent) Intergration (interneuron) Motor (brain to outside = efferent)

Autonomic (involuntary control)

Peripheral (around the body)

Sample Question 3
Describe the organisation of the nervous system in words.

The sensory division (sensory nerve fibres) conduct afferent impulses to the CNS through the peripheral nervous system (cranial and spinal nerves) which is the communication highways. At the central nervous system (brain and spinal cord) integration and control takes place and the message goes back through the peripheral nervous system to the motor division (motor nerve fibres) which is conducted through the efferent impulses to muscles and glands. This can be somatic (system voluntary) to the skeletal muscles or autonomic (system involuntary) to the smooth and cardiac muscles and glands. The autonomic system is split into two divisions; Sympathetic Division which mobilised body systems to deal with daily stress and the parasympathic division which conserves and replenishes energy.

The motor division conducts afferent impulses to the CNS through the peripheral nervous system.

The autonomic system is split into three divisions including the Sympathetic Division, Parasympathetic Division, and Neutral Division.

The sensory division is responsible for mobilizing body systems to deal with daily stress.
