Nervous System Review

Which layer of the meninges is closest to the brain?

• Arachnoid Mater

• Dura Mater

• Pia Mater

• Subarachnoid Space

What part of the neuron is covered in myelin and sends an impulse to the next neuron?

• Dendrite

• Soma

• Axon

• Synapse

What is the function of the brain stem?

• Controls basic life functions such as breathing, heartbeat, and blood pressure.

• Regulates emotional responses and memory processing.

• Coordinates voluntary muscle movements and balance.

• Processes sensory information and higher cognitive functions.

What is the difference between afferent and efferent neurons?

• Afferent neurons carry sensory information to the CNS; efferent neurons carry motor commands from the CNS.

• Afferent neurons carry motor commands from the CNS; efferent neurons carry sensory information to the CNS.

• Afferent neurons are responsible for reflex actions; efferent neurons are responsible for sensory perception.

• Afferent neurons transmit signals within the brain; efferent neurons transmit signals to the heart.

What is the role of neurotransmitters in the nervous system?

• They transmit signals across synapses between neurons.

• They protect neurons from damage.

• They store genetic information.

• They provide energy to the brain.

What is the function of the autonomic nervous system?

• Controls voluntary muscle movements such as walking and running.

• Regulates sensory perception and conscious thought processes.

• Controls involuntary bodily functions such as heart rate and digestion.

• Manages the body's response to external stimuli through reflex actions.

What is another name for the sensory division of the nervous system?

• Efferent

• Afferent

• Interneuron

• Motor

What part of the brain is responsible for 'muscle memory'?

• Cerebellum

• Hippocampus

• Frontal Lobe

• Amygdala

What is the role of the diencephalon in the nervous system?

• It acts as a relay center for sensory information and regulates autonomic functions.

• It is responsible for the production of hormones.

• It controls voluntary muscle movements.

• It is involved in the processing of visual information.

What is the primary function of the cerebrum?

• Regulating heart rate and blood pressure.

• Higher brain functions such as thought, action, and emotion.

• Controlling reflexes and involuntary actions.

• Processing sensory information from the body.
