Question

question 42 (2 points) which tract decussates within 1 - 2 segments of entry? spinothalamic dorsal column corticospinal vestibulospinal question 43 (2 points) what type of motor signs are seen in myelopathy below l1? upper motor neuron signs lower motor neuron signs both umn and lmn equally only sensory signs

Explanation:

For question 42, the spinothalamic tract decussates within 1 - 2 segments of entry. It is responsible for transmitting pain, temperature, and crude touch sensations. For question 43, myelopathy below L1 typically shows lower motor neuron signs as the lower motor neurons are directly affected in this region.
