Specialized support cells forming the myelin sheath in the peripheral nervous system.
What are the Schwann cells?
200
-70 mV
(Hoit et al., 2022)
What is resting membrane potential?
200
This cranial nerve controls three of the four extrinsic tongue muscles and intrinsic tongue muscles.
What is Cranial Nerve XII, the Hypoglossal nerve?
200
This lobe contains the primary motor cortex, which is associated with voluntary movements.
What is the Frontal Lobe?
300
The PNS comprises 12 pairs of these nerves and 31 pairs of these nerves.
(Murray, 2014)
What are cranial nerves and spinal nerves?
300
An event that occurs when the inside of the neuron rapidly becomes positive due to sodium ion influx.
What is action potential/depolarization?
300
The membrane potential continues to rise, reaching a peak value between +30mV and +40mV.
(Hoit et al., 2022)
What is overshoot peak?
300
This nerve has two branches; one is responsible for hearing, and the other is responsible for balance and spatial orientation.
What is the Vestibulocochlear nerve, Cranial Nerve VIII?
300
This lobe contains the primary somatosensory cortex, which is associated with touch, pain, and heat.
What is the Parietal Lobe?
400
This group of structures in the brain helps regulate motor movements and muscle tone, which are associated with Parkinson’s disease.
What is the basal ganglia, and what disease is it associated with?
400
Small gap between neurons where the neurotransmitters are released.
What is a synaptic cleft?
400
Maintained through the regulation of ion movement across the cell membrane.
What is similarities between resting and action potential?
400
The recurrent laryngeal nerve, which is a branch of CN X: Vagus, innervates all the intrinsic muscles of the larynx, except.
What is the cricothyroid?
400
_______ affects language skills to various degrees, while _______ affects motor speech production.

What is Aphasia and Apraxia?
500
These three structures make up the brainstem, which controls basic bodily functions such as breathing and heart rate.
(Cleveland Clinic, 2024)
What are the midbrain, pons, and medulla oblongata?
500
The name of a process by which neurotransmitters are reabsorbed into a presynaptic neuron after a synaptic transmission.
What is a reuptake?
500
Essential for nerve impulse transmission.
What is resting and action potential?
