What neuronal structure is found in the dorsal root ganglion? Can you identify this structure/s on the figure on the right? 11. Fill in the blanks of the following sentences. An impulse arriving from a somatic sensory neuron would go through the horn. This part of the spinal matter which is where neurons connect with one another . From that point, another neuron would travel tract in the white matter of the spinal cord. on the axons there. tract matter and would exit the spinal cord through the root before merging with root and enter the spinal cord through the cord is made up of otherwise known as to the brainstem through a/an White matter gets its color from the presence of A motor impulse coming from the brain would be traveling in a/an through the horn which connects with the the remainder of the spinal nerve.Explanation / Answer
ANSWER:10.
The DORSAL ROOT GANGLION :Ganglion is a cyst like structure which consists of several SOMA or CELL BODIES of the neurones .As the name implies the dorsal root ganglion consists of cell bodies of the ascending neurones which carry the sensory information from the body to the brain.In the above given diagram , the rounded oval structure with granular (cell bodies of neuron) appearance is the ganglion.
ANSWER:11.
An impulse arriving from a somatic sensory neuron would go through the ASCENDING POSTERIOR root and enter the spinal cord through the DORSAL horn.This part of the spinal cord is made up of WHITE matter which is where neurons connect with one another otherwise known as INTERNEURON .From that point , another neuron would travel to the brainstem through a SPINOTHALAMIC tract in the white matter of the spinal cord.White matter gets its color from the presence of MYELINATION on the axons there.A motor impulse coming from the brain would be travelling in a PYRAMIDAL AND EXTRAPYRAMIDAL tract through the grey matter and would exit the spinal cord through the ANTERIOR or VENTRAL horn which connects with the VENTRAL root before merging with the remainder of the spinal nerve.
