Amphid neurons are one group of sensory neurons that Caenorhabditis elegans(C. elegans)have.

Amphid Neurons: are sensory neurons; specifically chemosensory neurons which C.elegans use to sense chemicals. As a result of what these tiny animals sense, they can either decide to move toward the chemical (as with chemical attractants), away from the chemical (as with chemical repellants), or not at all...


'C. elegans have 12 pairs of bilaterally symmetric amphid chemosensory neurons. Their cell bodies, with dendrites that extend to the tip of the animals nose, are located outside of the nerve ring. The nerve ring, or nerve bundle, is where the axons of amphid neurons reside and make synaptic connections with neighboring cells.

Molecular profile

  • Neurotransmitter: _In response to stimuli, C. elegan neurons propagate an action potential and release biogenic amines such as dopamine, tyramine, and octopamine as neurotransmitter. C. elegan amphid neurons express tyramine as their neurotransmitter. One of the functions of tyramine is to inhibit head oscillations. __________
