What is the function of cerebrospinal fluid (CSF)?
It produces cerebral neurotransmitters.
It acts as a barrier to bacteria.
It acts as an insulator to maintain a constant spinal fluid temperature.
It cushions the brain and spinal cord.
The Correct Answer is D
Choice A rationale
Cerebrospinal fluid (CSF) does not produce cerebral neurotransmitters. Neurotransmitters are produced by neurons in the brain and nervous system.
Choice B rationale
CSF provides a protective barrier to some extent, but its primary function is not to act as a barrier to bacteria. The blood-brain barrier primarily serves this function.
Choice C rationale
CSF helps maintain a stable environment in the central nervous system but is not primarily an insulator for maintaining constant temperature. Its thermal properties are secondary.
Choice D rationale
The primary function of CSF is to cushion and protect the brain and spinal cord from mechanical injury. It also helps maintain the brain's buoyancy and provides a stable environment for the central nervous system.

Correct Answer is A
Explanation
Choice A rationale
The parietal lobe is responsible for processing sensory information and spatial awareness, including proprioception (the sense of body position in space). Damage to the parietal lobe can affect these functions.
Choice B rationale
The temporal lobe is involved in processing auditory information and memory, not spatial awareness. Damage to this lobe would affect hearing and memory rather than proprioception.
Choice C rationale
The frontal lobe is associated with executive functions, such as decision-making, problem-solving, and motor control, but not primarily with spatial awareness. Damage to this lobe impacts cognitive and motor functions.
Choice D rationale
The occipital lobe is primarily responsible for processing visual information. Damage to this lobe affects vision rather than spatial awareness or proprioception.
Correct Answer is C
Explanation
Choice A rationale
Deficient fluid volume is not the primary concern related to weight loss or ill-fitting dentures. While fluid intake should be monitored, it is less immediate than gastrointestinal issues from fiber deficiency.
Choice B rationale
Excessive intake of convenience foods might relate to weight loss but does not directly indicate a health risk. The primary risk is more focused on gastrointestinal function.
Choice C rationale
Constipation is a major risk due to limited fiber intake. Fiber is essential for bowel movement regularity, and its deficiency, coupled with ill-fitting dentures, increases the risk.
Choice D rationale
Infection is not directly related to the dietary concerns noted. While poor nutrition can weaken the immune system, it is not the most immediate health risk connected to the given symptoms. .
