Neural Communication and the Nervous System Quiz

Neuron is the fundamental unit responsible for transmitting nerve impulses.

Dendrites are the branches of a neuron that receive signals from other neurons.

Axons transmit nerve impulses away from the cell body.

Terminal buttons release neurotransmitters into the synapse, facilitating communication between neurons.

Myelin acts as an insulating layer around axons, facilitating faster transmission of nerve impulses.

The medulla oblongata controls involuntary functions like breathing and heart rate.

CSF cushions the brain and spinal cord, providing protection against mechanical injuries.

The parasympathetic nervous system controls bodily functions like digestion and relaxation during rest.

Dopamine is linked to pleasure, reward, and motivation.

The hypothalamus controls various bodily functions, including temperature regulation and metabolism.

Acetylcholine is involved in muscle movement, memory, and cognitive function.

Neurotransmitters relay signals between neurons across synapses.

The blood-brain barrier prevents harmful substances from entering the brain tissue.

The prefrontal cortex is involved in executive functions such as decision-making, planning, and emotional regulation.

The reticular formation plays a crucial role in regulating arousal, consciousness, and sleep-wake cycles.

The frontal lobe is responsible for executive functions such as decision-making, planning, and emotional regulation.
