Neurones

Question 1

Neurones

Answer 1

• Nerve cells
• Specialised cells adapted for rapidly carrying electrochemical changes = Nerve impulses
• From one part of the body to another

Question 2

Three types of neurone

Answer 2

1. Sensory
2. Intermediate
3. Motor

Question 3

Sensory neurone

Answer 3

Function
- Transmit nerve impulses from a receptor to an intermediated or motor neurone

Cell adaption

• One very long dendron
• Carrie impulse towards cell body
• One axon that carries it away from the cell body

Question 4

Intermediate neurone

Answer 4

Function
- Transmit impulses between neurones

Adaption
- Numerous short processes

Question 5

Motor neurone

Answer 5

Function
- Transmit never impulses from an intermediate to effector
= Muscle or gland

Cell adaption

• Long axon
• Many short dendrites
