The following is true about the frontal lobe of the brain:

Correct Answer: B

Rationale: The frontal lobe controls behavior (B, prefrontal), not taste (A, temporal), has motor areas (C, partial), and memory loss (D) is more temporal/hippocampal. B is most accurate.

Correct Answer: A

Rationale: The anterior horn (A) contains somatic motor neurons controlling skeletal muscles. The posterior horn (B) processes sensory input, lateral horn (C) houses autonomic neurons, and alar plate (D) is an embryonic term region, not adult structure. A is correct.

Correct Answer: C

Rationale: Autonomic ganglia (C) contain neurons regulating homeostasis (e.g., heart rate, digestion) via the autonomic nervous system. Sensory (A) and dorsal root ganglia (B) handle sensation, and cranial nerve ganglia (D) vary. C is correct.

Correct Answer: D

Rationale: In the peripheral nervous system (PNS), a bundle of axons is called a nerve. A nucleus refers to a cluster of cell bodies in the CNS, a ganglion is a cluster of cell bodies in the PNS, and a tract is a bundle of axons in the CNS.

Correct Answer: C

Rationale: Chemoreceptors detect chemical stimuli, such as molecules (e.g., odors or tastes), in the environment or body. Thermoreceptors detect temperature, not light, sound, or vibration.
