1
Q

What is involved in the nervous system?

A

Cranial - eyes mouth ears
Central nerves - brain spinal cord
Autonomic - heart lung, sex organs
Peripheral - arms hands, legs

2
Q

What is the parasympathetic NS responsible for?

A

Parasympathetic - tries to calm you down, slows heart rates, breathing - tries to bring you back to homeostasis.

3
Q

What is the sympathetic NS responsible for?

A

Sympathetic - allows heart rate to increase, breathing rates, adrenaline. production on insulin. Reaction to the environment

4
Q

What does the motors neurones do?

A

Conducts impulses from CNS to effectors

5
Q

What does the Somatic neurones do?

A
  • Voluntary

- conduct impulses from the CNS to skeletal muscles

6
Q

What makes up a motor unit

A

Muscle fibres

Motorneurone

7
Q

What is a motor neurone composed of?

A

Dendrites - connect with other neurones

Axon - nerve fibre - pass the signals.

Myelin sheath - like an insulator for the axon to transmit the signal

Nerve endings - connect with muscle or gland

8
Q

What are the factors affecting global motor unit recruitment?

A
  • Force requirement
  • Muscle fatigue
  • Energy state of the muscle (ATP and oxygen availability)
  • Peripheral motor control stretch reflex
  • Muscle energetics and neuromuscular regulation
9
Q

What prevents your muscle from overextending?

A

Gorgi tendon

10
Q

What affects the muscle fibre conductance velocity?

A
  • Discharge rate
  • Fibre diameter
  • Ion concentration
  • pH
  • Temperature
  • Muscle fibre
11
Q

When is the muscle fibre conduction velocity high?

A

With the aid of sodium bicarbonate Signal being conducted at a muscle faster rate.

12
Q

The larger the diameter of muscle fibre the fast the MFCV. TRUE OR FALSE?

A

TRUE

13
Q

The larger the diameter of muscle fibre the fast the MFCV. TRUE OR FALSE?

A

TRUE

Thicker is faster
Distance is larger but there is a faster speed

14
Q

Why is the neurone signal faster in MS patients?

A

Less insulation - less resistant from the Myelin sheath
