Exam 4 review

Front

What is the role of the thalamic nuclei in sensory processing?

Back

The thalamic nuclei are responsible for sorting and editing sensory impulses before they reach the cerebral cortex.

Front

Which cranial nerve is NOT involved with the eye?

Back

The trigeminal nerve is not involved with the eye; it primarily provides sensation to the face.

Front

What occurs at an electrical synapse?

Back

Ions flow directly from one neuron to the next, allowing for rapid communication between neurons.

Front

What is the function of the visceral sensory area of the cerebral cortex?

Back

It is involved in the conscious perception of visceral sensations, such as a full bladder or upset stomach.

Front

What are nociceptors sensitive to?

Back

Nociceptors are sensitive to pain.

Front

Define sensory impulse sorting.

Back

Sensory impulse sorting is the process by which the brain organizes and prioritizes sensory information for further processing.

Front

What is the function of the prefrontal cortex?

Back

The prefrontal cortex is involved in complex cognitive behavior, decision making, and moderating social behavior.

Front

What is the role of neurotransmitters in synaptic transmission?

Back

Neurotransmitters are chemicals that transmit signals across a synapse from one neuron to another.

Front

Explain the difference between electrical and chemical synapses.

Back

Electrical synapses allow direct ion flow between neurons, while chemical synapses involve neurotransmitter release.

Front

What is the significance of the postcentral cortex?

Back

The postcentral cortex is the primary somatosensory area, responsible for processing tactile information.
