Correct Answer: D

Question 2 of 4
The meninx in contact with the brain and spinal cord is the:

Question 3 of 4
Body temperature, sensory perception, and the onset of sleep are partially regulated by the neurotransmitter:
Correct Answer: B
Rationale: Serotonin influences body temperature (hypothalamus), sensory perception (modulation), and sleep (via raphe nuclei). Glycine is inhibitory, acetylcholine aids arousal, dopamine affects movement, and enkephalins reduce pain.
Question 4 of 4

Correct Answer: D
Rationale: All listed are involved: substance P transmits pain signals, thalamus relays them, enkephalins modulate pain, and posterior horns (spinal cord) receive sensory input. 'None of the above' is incorrect.
