Question

The nurse is assessing the touch, pain, and temperature sensation of a patient who is diagnosed with diabetic neuropathy. Arrange in ascending order the parts of the central nervous system through which pain sensation is carried.

A)Cerebrum
B)Thalamus
C)Spinal cord
D)Medulla, pons, midbrain

Answer 1

The ascending pathway for pain sensation in the central nervous system is arranged in the following order: Spinal cord, Medulla, pons, midbrain, Thalamus, Cerebrum.

Step-by-step explanation:

The ascending pathway for pain sensation in the central nervous system is arranged in the following order:

1. Spinal cord: Pain sensation starts at the sensory receptors, and nociceptive information is carried by axons in the spinal cord.
2. Medulla, pons, midbrain: Some nociceptive pathways project directly to the hypothalamus in the forebrain, modulating autonomic nervous system functions.
3. Thalamus: Most nociceptive axons project to the thalamus, where sensory signals undergo final processing before being relayed to the primary somatosensory cortex.
4. Cerebrum: The primary somatosensory cortex in the cerebrum perceives pain.
