Nervous System and Sensory Biology Quiz Review

Vocabulary flashcards covering key concepts from quiz questions on the nervous system, neural signaling, and sensory receptors.

Cerebellum

The part of the brain responsible for coordination of movement.

Reflex action

A neural, automatic stimulus-response.

Action potential arrival at synaptic terminal

The process at the end of presynaptic neurons where calcium ions enter the synaptic terminal and cause synaptic vesicles to release neurotransmitter into the synaptic cleft.

Reception

The first step in the neural signaling process.

Myelin

A substance that covers some neurons and speeds the conduction of nerve impulses.

Inner ear

The structure that contains mechanoreceptors that convert sound waves to nerve impulses.

Stimulus

Any detectable change in the internal or external environment.

Thermoreceptors

Receptors that respond to heat and cold.
