receptors
these are wire-like projections from the main cell body, which are often further branched and carry impulses to the cell body. theses are called dendrites.
Receptors or more precisely, sensory receptors.
sensory? im not sure
If a neuron receives a series of stimuli that have an excitatory effect but do not reach the threshold for action potential initiation, the neuron will not fire. This is because the individual stimuli do not generate a strong enough depolarization to reach the threshold. However, if enough subthreshold stimuli are received in a short period of time, they can summate and reach the threshold, generating an action potential.
