Question

The chemical causing the transmission of the nerve impulse across synpase/end plate is

• A. Choline esterase
• B. Acetylcholine
• C. Choline
• D. Adrenaline

Answer 1

The correct option is B Acetylcholine

The neurotransmitters are the chemicals responsible for the transmission of the nerve impulse from a neuron either to the post-synaptic neuron, muscle or to a gland. The synapse is formed between two neurons. The end plate is a junction of the motor neuron and muscle. The acetylcholine is a neurotransmitter that allows the transmission of the nerve impulse.

A. Choline esterase is an enzyme which breaks the transmission by hydrolizing the acetylcholine.

B. Acetylcholine is a neurotransmitter.

C. Choline is an ingredient of the neurotransmitter.

D. Adrenaline is a hormone.

Hence, the correct answer is 'Acetylcholine'
