Title: somatic motor reflexes Post by: sgarmstr on Jul 12, 2014 Where would you find the cell body of the sensory neuron that stimulates a response?
Title: Re: somatic motor reflexes Post by: skip5284 on Jul 12, 2014 The cell bodies of the sensory neurons leading to the spinal cord are located in clusters, the dorsal root ganglia, next to the spinal cord. Their axon extends in both directions: a peripheral axon to receptors at the periphery and a central axon passing into the spinal cord. The latter axon usually terminates at an interneuron.
The diagram is a simplified view of the relationship between sensory and motor neurons running to and from the spinal cord. (http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/S/SpinalCord.gif) |
