Cranial Nerves
This cranial nerve is responsible for the sense of smell.
What is the olfactory nerve (CN I)?
This system includes the cerebral hemispheres, brainstem, and spinal cord.
What is the Central nervous system?
This lobe contains the primary motor cortex and helps control voluntary movement.
What is The Frontal Lobe?
Which part of a neuron picks up signals from other neurons and expands the cell’s receptive surface?
What are dendrites?
Which nerve pathways send sensory info from your body up to your central nervous system?
What are afferent tracts?
This cranial nerve controls vision and transmits sensory information from the retina to the brain.
What is the optic nerve (CN II)?
This system includes the nerves located outside the brain and spinal cord.
What is the Peripheral nervous system?
This lobe contains the primary somatosensory cortex and processes touch, pain, and pressure.
What is the Parietal Lobe?
What's the long fiber that sends electrical messages from the cell body out to other neurons or muscles?
What is the axon?
Which pathways take commands from your central nervous system out to your muscles and glands?
What are efferent tracts?
This cranial nerve controls facial expressions, provides taste sensations to the anterior two-thirds of the tongue and stimulates tear and saliva production.
What is the facial nerve (CN VII)?
This type of matter is mainly formed by neuron cell bodies.
What is Gray matter?
This lobe contains the primary auditory cortex and is important for hearing and language comprehension.
What is the Temporal Lobe?
This coating around the axon helps nerve signals travel much faster by letting them jump along.
What is the myelin sheath?
This major nerve tract starts in the motor cortex and handles voluntary limb movements.
What is the corticospinal tract?
This cranial nerve is responsible for hearing and balance through sensory information from the inner ear.
This type of matter is mainly formed by myelinated axons
What is White Matter?
This lobe contains the primary visual cortex.
What do you call the tiny spaces between sections of myelin where action potentials leap and speed up neural signals?
What are the nodes of Ranvier?
Which pathway controls the muscles in your face, jaw, and tongue using cranial nerves?
What is the corticobulbar tract?
Damage to this cranial nerve can result in difficulty moving the tongue, affecting speech and swallowing abilities.
What is the hypoglossal nerve (CN XII)?
A bundle of axons inside the central nervous system is called this.
What is tract?
This area of the left frontal lobe is involved in planning and organizing movements for speech production.
What is Broca's area?
At the end of a neuron, which part releases neurotransmitters into the gap to talk to the next cell?
What is the axon terminal?
These are the pathways—like the ones involving the basal ganglia—that keep your posture steady, adjust muscle tone, and manage automatic movements.
What are the extrapyramidal pathways?
