Question 1

What does the nervous system consist of?

Answer 1

The nervous system consists of the brain, spinal cord, and a complex network of neurons.

Question 2

What is the nervous system responsible for?

Answer 2

• This system is responsible for sending, receiving, and interpreting information from all parts of the body.

Question 3

What two parts can the nervous system be divided into?

Answer 3

• the central nervous system and the peripheral nervous system

Question 4

What are the two main organs of the CNS?

Answer 4

• brain and spinal cord.

Question 4

What is the function of the striatrium?

Answer 4

• Important role in controlling movements and in motivation

Question 5

What is the function of the hippocampus?

Answer 5

Short-term memories are passed into long-term memory via the hippocampus

Question 6

What is the function of the ventricles?

Answer 6

• Produce cerebrospinal fluid to cushion brain and provide nutrients

Question 7

What is the function of the amygdala?

Answer 7

Question 10

What is the function of the cerebellum?

• Stores memory/ learning of practical skills

Question 11

What is the function of the corpus callosum?

Answer 11

• The bridge between the two hemispheres of the brain and transmits messages between the two halves

Question 12

What is the function of the limbic system?

Answer 12

• Concerned with emotions and memories, includes the hypothalamus, hippocampus and amygdala

Question 13

What does the spinal cord do?

Answer 13

The spinal cord receives information from the skin, joints and muscles of the body. It also carries the nerves that control all movements.

Question 14

What does the brain do?

Answer 14

The brain is the most complicated part of your nervous system; it receives information directly from the ears, eyes, nose and mouth, as well as from the rest of the body via the spinal cord.

Question 15

What are neurons?

Answer 15

• Neurons (nerve cells in the brain) receive and transmit messages in the brain (from cell to cell) in response to the information received from the rest of the body.

Question 16

What are synpases?

Answer 16

• Information travels along neurons as electrical signals – nerve impulses. These signals are passed to the next neuron in the chain at special sites known as synapses.
