The posterior Root Ganglion (Dorsal root ganglion) houses the cell bodies of sensory neurons.
Dorsal root ganglion is a cluster of neurons located in the dorsal root of a spinal nerve,which mainly contain Cell bodies of Sensory Neurons that carry Dorsal Column sensations like
1.Fine touch
2.Position Sense
3.Twon Point Discrimination
4.Vibration Sense
5.Stereognosis etc

11) A tumor is found compressing the dorsal root ganglion of the 3rd thoracic region. Which deficiency would you expect the patient to have? (1 point) A) Movement of the arm B) Pressure sensations on the shoulder C) Movement of the leg D) Movement of the head or neck E) Itching sensations in the foot 12) Damage to the L3 nerve root would cause all of the following symptoms EXCEPT (1 point) A) Adduction of the thigh...

The spinal cord has a segmental organization, and as a result: A. Each posterior (dorsal) spinal root innervates muscles found in the arms and legs, and this is referred to as a myotome. B. Each posterior (dorsal) spinal root carries sensory information from a specific area of skin, referred to as a dermatome. C. Efferent (motor) neurons in the posterior (dorsal) horn innervate muscles and organs from a single spinal cord segment. D. All sensory information from the periphery enters...

(1) Explain why neural crest cells migrating in the path2 migrate into the anterior but not posterior somite. Use terms: ephrin, Eph. (Ept) (2) In the intact condition of mouse, the Notch signaling keeps the neural precursors in an immature c proliferation state to expand the number of neuronal cells in later. Explain what will happen if the constitutive active form of Notch (continuously active Notch) is...
