Which label points to the sensory neurone?

Below are two statements about how neurones work :

1 - Neurotransmitters carry a nerve impulse along a neurone.

2 - An electrical charge carries a nerve impulse across a synapse.

Which of these statements is/are true ?

Which part of the neurone carries a

nervous impulse towards the cell body?

Which part of neurone

speeds up the nervous impulse?

Which part of the neurone

releases neurotransmitter?

Which part of the neurone

initiates the nervous impulse?

Which type of neurone carries a nervous

impulse from the CNS to an effector?

What is the correct order of events that occur at a synapse ?

P – Neurotransmitter diffuses across the synapse

Q – A nervous impulse arrives at the synaptic knob

R – Neurotransmitter binds to receptors in the cell membrane

S – Vesicles release neurotransmitter into the synapse
