Question 2

What are the roles of the nervous system?

Answer 2

Input

Analysis

Output

Answer 4

2

Question 5

What is the left side of the brain used for?

Answer 5

Responsible for controlling the right side of the body (logic tasks)

Question 6

What is the right side of the brain used for?

Answer 6

Responsible for controlling the left side of the body (creativity tasks)

Question 7

What are the 3 main parts of the brain?

Answer 7

Cerebrum

Cerebellum

Brain stem

Question 8

What is the Cerebrum?

Answer 8

Largest part of the brain and is composed of the right and left hemisphere

Question 9

What is the Cerebellum?

Answer 9

Located under the cerebrum, controlling the actions of your muscles and storing memories

Question 10

What is the Brainstem?

Answer 10

Acts as a relay centre connecting the cerebrum and cerebellum to the spinal cord

Question 11

What is the Central nervous system and it’s function?

Answer 11

Consists of the brain and the spinal cord. Responsible for all conscious and unconscious decision making

Question 12

What is the Spinal cord responsible for?

Answer 12

Responsible for controlling reflex reactions and also provides the means for connecting the brain to the nerves that supply the rest of the body

Question 13

What is the Peripheral nervous system and it’s function?

Answer 13

The name used to describe all of the branches of nerves outside of the central nervous system

It transmits info to and from the CNS

Question 14

What is a Neuron?

Answer 14

Designed to transmit information rapidly in response to changes inside and outside of the body

Question 15

What is the structure of a Neuron?

Answer 15

Cell body

The Axon

Dendrites

Myelin sheath

Neurotransmitters

Question 16

What is the function of Neurotransmitters?

Answer 16

Maintain balance within the nervous system

Question 17

What is a Motor unit?

Answer 17

Muscles made up of bundles of muscle fibres arranged into groups

Consists of anywhere between 10 and 1000 muscle fibres

Question 18

What are the responses of the neuromuscular system to exercise? (ACUTE CHANGES)

Answer 18

Vasodilation of blood vessels

Increased temperature

Blood diverted away from non-essential organs to working muscles

Reduced nervous inhibition

Question 19

What are the responses of the neuromuscular system to exercise?
(CHRONIC CHANGES)

Answer 19

Exercise: 
frequency
duration
Volume
Intensity
Modality

Question 20

What are the long term adaptations to resistance training?

Answer 20

Increased cross-sectional size of muscles

Improved balance and coordination

Increased strength due to hypertrophy

Increased strength due to decreased nervous inhibition

Question 21

What are the long term adaptations to Aerobic exercise?

Answer 21

Increase in the size and number of energy-producing mitochondria

Increase in capillarisation surrounding muscle fibres at the alveoli

Increase in aerobic enzyme activity stored glycogen and triglycerides in the muscle fibres
