Reflexes are important for:

Learning complex behaviors
Conscious thought processes
Maintaining homeostasis and protecting the body
Voluntary movement control

The latency of a reflex refers to:

Its strength
The time delay between stimulus and response
Its predictability
Its ability to be conditioned

The withdrawal reflex (e.g., from a hot object) is an example of a:

Monosynaptic reflex
Stretch reflex
Polysynaptic reflex
Cranial reflex

Which part of the central nervous system typically serves as the integration center for simple spinal reflexes?

Cerebrum
Cerebellum
Brainstem
Spinal cord

Most reflexes in the human body are:

Monosynaptic
Polysynaptic
Conditioned
Voluntary

The knee-jerk reflex is an example of a:

Polysynaptic reflex
Conditioned reflex
Monosynaptic reflex
Voluntary action

A reflex arc that involves one or more interneurons between the sensory and motor neurons is:

Monosynaptic
Polysynaptic
Autonomic
Somatic

A reflex arc that involves only two neurons (one sensory, one motor) and one synapse is called:

Polysynaptic
Monosynaptic
Afferent
Efferent

What is the cell or organ that responds to the motor neuron’s command in a reflex arc?

Receptor
Sensory neuron
Effector
Integration center

In a reflex arc, where does the processing and decision-making (even simple) occur?

Receptor
Motor neuron
Integration center (CNS)
Effector

Which neuron transmits the command from the CNS to the effector?

Sensory neuron
Interneuron

Sensory neuron
Receptor

What is the neural pathway that mediates a reflex action?

Nerve tract
Reflex arc
Neural network
Synaptic chain

Which neurotransmitter is involved in mood, sleep, appetite, and can be targeted by antidepressant drugs?

Dopamine
Norepinephrine
Serotonin
Acetylcholine

What is a rapid, involuntary, predictable motor response to a stimulus?

Conscious decision
Voluntary action
Reflex
Learned behavior

The main inhibitory neurotransmitter in the brain is:

Glutamate
Acetylcholine
Serotonin
GABA

Which neurotransmitter is commonly associated with muscle contraction?

Dopamine
Serotonin
Acetylcholine
GABA

An inhibitory postsynaptic potential (IPSP) causes the postsynaptic membrane to:

Depolarize
Repolarization
Hyperpolarize
Generate an action potential
