The soma of sensory neurons are contained in the dorsal root ganglia just a short distance outside the spinal cord, and are pseudo-unipolar neurons, which do not have dendrites, but rather one projection (hence uni-polar) from the soma which bifurcates into two AXONS, one of which is long and goes to the receptor, and the other shorter one returns via the dorsal root into the spinal cord. The fact that the longer one from the receptor is an axon is what allows the strength of the signal to be maintained from the receptor than a dendrite would allow.

Does anyone know if calcium still enters the preganglionic neuron via voltage gated channels in order to release ACh to the ganglion? And is the action potential started again in the postganglionic neuron because Na diffused in after ACh binded causing the cell to depolarize?

how adrenaline is secreted? either direct from ganglion or ACH convert into adrenaline

@ambalikasarkar1709 9 жыл бұрын

Thank you very much! I have a question here, since you seem to be proficient in neuroscience: how is the sympathetic nervous system triggered by visual cues? does the signal come directly from the visual cortex to the pre-ganglionic neuron via the spine? or does it have to pass through the amygdala and other regions in the hind brain region? I am asking this because I presume that an animal wont have much time to react in situation of a visible danger, hence can the amygdala etc be by-passed?

@free2saywhatever 8 жыл бұрын

Actually visual input is pretty quick. Less than a few microseconds. Most of the time it will be a cranial/brainstem reflex if an animal is in danger. At the same time some neurons would go down and activate motor neurons in the ventral horn of the spinal cord which will release acetylcholine/norepinephrine to trigger fight or flight response. It would be somatic nervous system activity at point, not so much autonomic.

A very nice vid! However, you create some confusion at the very beginning (1:00) - when you draw a sensory neuron. This purple neuron seems to have it's body (indicated by the star) in the CNS, while it should normally be closer to periphery. Also it's projection conducting nerve impulse from a receptor to the body looks like the only long axon, while it should be one of many dendrites. In other words, this neuron has wrong direction.

@dannichols6261 5 жыл бұрын

@Yevgen Kiosya, I think you're mistaken, in that the soma of sensory neurons are contained in the dorsal root ganglia just a short distance outside the spinal cord, and are pseudo-unipolar neurons, which do not have dendrites, but rather one projection (hence uni-polar) from the soma which bifurcates into two AXONS, one of which is long and goes to the receptor, and the other shorter one returns via the dorsal root into the spinal cord.
