ZFIN Phenotype Statement: Mauthner neuron dendrite gjd2a expression decreased amount, abnormal

Phenotype:	Mauthner neuron dendrite gjd2a expression decreased amount, abnormal
Note:	This phenotype statement describes a gene expression or antibody labeling pattern. Anatomy terms are combined with a gene or antibody and phenotype quality.

EXPRESSION ANATOMY:

Name:	Mauthner neuron
Synonyms:
Definition:	Is a hindbrain interneuron. Giant reticulospinal neurons possessing thick crossed axons and positioned dorsally in the hindbrain tegmentum at the level of entrance of the eighth cranial nerve. The Mauthner neuron is paired. The M-cell has two large invariant dendrites: The lateral dendrite terminates in the sensory neuropil of the acoustico-lateral area, and the ventral dendrite terminates in the neuropil of the motor tegmentum. Fine dendrites are present, and mostly arise from three regions; from the terminus of each major dendrite and from the ventral surface of the perikaryon.

Name:	dendrite
Synonyms:
Definition:	A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
