Steps in impulse transmission

Answer 1

Brain send the message via nerve impulses involving neurons which use the neuro-transmitter Acetylcholine

Each nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.

Acetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle

action potential, which leads to muscle contraction

Answer 2

Impulses are transmitted along by what is referred to as an action potential. This action potential travels along the semipermeable membranes of nerve and muscle cells as it changes polarity from positive to negative via the transference of sodium and potassium ions.
