Explanation / Answer

what happens when neurotransimtters bind the the afferent neruon?

The sensory neurons detect odorants and would be possessing small proteins or odorants receptors which are present in the membrane. Part of the neurons that are exposed to environment would be enlarged frequently by cilia as well as microvili. When the neurotransmitter binds to the sensory neurons, there would be opening of the gated channels. There are receptors at the ending which result in generation of action potentials In response to the stimulus. These action potentials get transmitted through the axon length in the direction of the spinal cord.
