What is neurotransmitters?

An example of a neurotransmitter.

In the neurilemma, the synaptic vesicles release neurotransmitters into the synaptic ciert by …………………… .

Two neurons, A and B, synapse onto a third neuron, C.If neurotransmitter from A opens ligand-gated channels permeable to Na^+ and K^+ and neurotransmitter from B opens ligand-gated Cl^- channels, which of the following statements is true ?

During synaptic transmission of nerve impulse, neurotransmitter (P) is released from synaptic vesicies by the action of ions (Q). Choose the correct P and Q.

Following is given a randomly arranged list of events that occur at neuromuscluar junction to trigger mucle contraction. (i) Receptor sites on sarcolemma Nerve impulse (iii) Release of Ca^(+2) from sarcoplasmic reticulum (iv) The neurotransmitter acetylcholine is released (v) Sarcomere shorten (vi) Synaptic cleft (vii) Spread of impulses over sarcolemmna on T-tubules Which of the following gives the correct sequence of these steps?
