Which part of a neuron conducts nerve impulses to another cell?

Correct Answer: A

Rationale: Synaptic ends (terminals) release neurotransmitters to signal another cell, concluding the axon’s impulse conduction. Axon conducts, dendrites receive, and cell body processes.

Correct Answer: D

Rationale: The straight sinus is formed by the union of the inferior sagittal sinus (along the falx cerebri) and the great cerebral vein (Galen), draining into the confluence of sinuses. The superior sagittal sinus contributes to other sinuses, and the transverse sinus is downstream.

Correct Answer: D

Rationale: Neuroglia (e.g., astrocytes, oligodendrocytes) support and nourish neurons. Dendrites and axons are neuron parts, and neurotransmitters are chemicals.

Correct Answer: B

Rationale: Depolarization is Na+ influx making the inside positive, initiating an action potential. Polarization is resting state, repolarization restores it, and hyperpolarization overshoots.

Correct Answer: D

Rationale: CSF is in brain ventricles, subarachnoid spaces, and the spinal cord’s central canal, circulating to cushion and support the CNS.
