Question 1

What is the Central Nervous System (CNS)?

Answer 1

Brain and Spinal cord only.

Question 2

What is the Nervous System?

Answer 2

Brain, Spinal cord, and Nerve.

Question 3

What are the 4 parts of the Brain?

Answer 3

Cerebrum
Cerebellum
Medulla
Spinal Cord

Question 4

What is the Cerebrum?

Answer 4

Memory, Thought, Imagination, Intelligence, and Reasoning.

Question 5

What is the Cerebellum?

Answer 5

Balance and Muscle Co-ordination?

Question 6

Answer 6

Breathing Rate and Heart Rate.

Question 7

What are the 3 types of Nerves?

Answer 7

Sensory
Inter
Motor

Question 8

What is the Sensory Nerve (Neurone)?

Answer 8

Electrical impulses from sensory organs to the CNS.
Impulses travel in 1 direction towards CNS.

Question 9

What is the Inter Neurone?

Answer 9

Only found within the CNS (Brain and Spinal Cord).
It connects the sensory and motor neurons.

Question 10

What is the Motor Neurone?

Answer 10

Electrical impulses from CNS to the muscle/gland.
Fast response=Muscle.
Slower response=Gland.

Question 11

What are Nerve Impulses?

Answer 11

The information that triggers a nerve impulse = stimulus.
Muscle contract = effectors brings about a response.

Question 12
