Which of the following is a less disabling form of HIV dementia?

Correct Answer: A

Rationale: Minor Cognitive Motor Disorder (MCMD) is a less severe form of HIV-associated cognitive impairment. It is characterized by mild memory loss, reduced cognitive function, and slight motor difficulties. Unlike HIV dementia, which significantly impacts daily functioning, MCMD allows individuals to maintain a relatively normal level of independence and quality of life, although they may still experience some cognitive challenges.

Correct Answer: A

Rationale: The central nervous system (CNS) consists of the brain and spinal cord. It is responsible for processing and integrating sensory information and coordinating motor responses. The brain is the control center for thought, emotion, and behavior, while the spinal cord serves as a conduit for signals between the brain and the peripheral nervous system. The CNS plays a central role in maintaining homeostasis and responding to external and internal stimuli.

Correct Answer: B

Rationale: Sensory nerves contain only afferent fibers, which are the long dendrites of sensory neurons. These fibers transmit sensory information from the body to the central nervous system. Cranial nerves and mixed nerves contain both afferent and efferent fibers, while motor nerves contain only efferent fibers. Therefore, sensory nerves is the correct answer as they exclusively carry afferent signals.
