Question

Describe the similarities and differences between the structure and function of interneuronal synapses and neuromuscular junctions.

Accepted Answer

Similarities between the interneuronal synapses and neuromuscular junctions are that both are stimulated by the action potential on the presynaptic membrane. Both have postsynaptic receptors on their surface for the binding of neurotransmitters. Both are depolarised on the postsynaptic membrane and show response.

Differences Interneuronal synapses Neuromuscular junctions (NMJ)

Structure This is a junction between the two neurones, that is the axon of a neurone and the dendrite of the other impulse receiving neurone. This is a junction between the nerve fiber and a muscle cell.

Function These could be excitatory or inhibitory and lack T-tubules. These are excitatory only and have T-tubules to carry signals faster.
