Chapter 2 Synapses And Reflexes

Question 1

What do synapses do.

Answer 1

Synapses connect neurones

Question 2

What is a synapse

Answer 2

The connection between 2 neurones . Where the nerve signal is transferred by neurotransmitters which diffuse across the gap ( synapse ) between the neurones
This then sets off a new electrical signal in the next neurone causing a chain reaction

Question 3

What are reflexes

Answer 3

Reflexes are automatic rapid responses to stimuli

Question 4

What is the process. Of a REFLEX ARC ( receptor to effector )

Answer 4

1 stimuli
2 stimulation of receptor
3. Impulses travel along sensory neurone
4. Impulses are passed along a relay neurone vis a synapse
5. Impulses travel along a motor neurone via synapse
6. When impulse reaches muscle it contracts
