Question

please correct my answers in bold if ,they are wrong

10. Where do somatosensory axons cross within the central nervous system?

Crosses at decussation of medial lemniscus

11. Where do nociceptive axons cross within the central nervous system?  

The spinal cord primarily in the anterior region and thus called the anterior spinal thalamic tract

12. What are the two tracts that carry ascending sensory information to the brain?

The dorsal column system (sometimes referred to as the dorsal column–medial lemniscus) and the spinothalamic tract

13. Which two thalamic nuclei receive sensory information from the body and face?

I dont know

Answer 1

10. Answer:- your answer is right.

Explanation:-

somatosensory system cross the midline at sensory decussation in the medulla, forming medial lemniscus which connects with thalamus.

11. Answer:- your answer is right.

Explanation:-

The nociceptive axons cross over (decussate) to the opposite side of spinal cord via tha anterior white commissure , that's why called anterior spinothalamic tract.

12. Answer:- your answer is right.

Explanation:-

The two ascending tracts that carries sensory information to the brain -

(A) dorsal column medial leminscus system

(B) spinothalamic tract

13. Answer:- sensory relay nuclei of thalamus that recieves signals from body and face -

(A) ventral posterior nucleus

(B) lateral and medial geniculate nucleus
