Human Nervous System and Physiology Quiz

Dendrites are the branch-like structures of a neuron that receive signals from other neurons and transmit them towards the cell body.

The autonomic nervous system controls involuntary functions, such as digestion and heartbeat, to maintain internal balance.

The medulla oblongata is responsible for regulating essential functions such as heartbeat and breathing.

Dopamine is a neurotransmitter that plays a key role in the brain's reward system and is associated with feelings of pleasure and reward.

The cerebellum is responsible for coordinating voluntary muscle movements and maintaining balance.

The sympathetic nervous system activates the body's fight-or-flight response, preparing it to face a perceived threat or danger.

Serotonin is a neurotransmitter that regulates various functions, including sleep, mood, and appetite.

The hypothalamus plays a key role in maintaining homeostasis, including the regulation of body temperature.

The frontal lobe is responsible for motor function, decision making, and other higher cognitive processes.

The temporal lobe is primarily involved in processing auditory information and is crucial for language comprehension.

Parkinson's disease is characterized by a deficiency of dopamine, a neurotransmitter involved in motor control.

Depolarization involves the influx of sodium ions into the neuron, causing a shift in membrane potential towards positivity.
