cranial nerves
This wandering cranial nerve provides parasympathetic input to the heart, lungs, and digestive tract, and also carries taste from the epiglottis.
What is the vagus nerve? (X)
The glial cell that produces the myelin sheath in the PNS
What is the Schwann cell?
This set of four major regions includes the cerebrum, cerebellum, diencephalon, and brainstem.
What are the principal regions of the brain?
This ion is primarily responsible for depolarizing the neuron at the start of an action potential.
What is sodium?
This ambitious rabbit becomes the first bunny police officer in the city of Zootopia, proving that even the smallest can make a big impact.
Who is Judy Hopps?
This first cranial nerve carries information about smell from the nose to the brain.
What is the olfactory nerve? (I)
These specialized glial cells in the central nervous system act as the brain’s primary immune defense, removing debris, damaged neurons, and pathogens.
What are microglia?
This major nerve of the upper limb travels through the carpal tunnel and is compressed in the most common entrapment neuropathy.
What is the median nerve?
The phenomenon in which an action potential “jumps” from one node of Ranvier to the next in a myelinated axon is called this.
What is saltatory conduction?
This Mariah Carey song, released in 1994, has repeatedly topped holiday charts worldwide and has become a perennial staple on radio and streaming platforms every December.
What is “All I Want for Christmas Is You”?
This cranial nerve controls most eye movements and also constricts the pupil.
What is the oculomotor nerve? (III)
These glial cells surround neuronal cell bodies in peripheral ganglia, regulating their microenvironment and helping control nutrient and waste exchange.
What are satellite cells?
Responsible for modulating and initiating movement, this dopamine-producing midbrain region degenerates in Parkinson’s disease.
What is the substantia nigra?
This basal ganglia pathway facilitates voluntary movement and is underactive in Parkinson’s disease.
What is the direct pathway?
In Season 3 of Stranger Things, this witty Hawkins resident proudly notes that her name contains all the letters needed to spell her home country.
Who is Erica?
A patient presents with tongue deviation toward the side of the lesion when protruding it. Damage to this cranial nerve is suspected.
What is the hypoglossal nerve (XII)?
Lining the ventricles of the brain and the central canal of the spinal cord, these ciliated glial cells help circulate cerebrospinal fluid and form part of the blood–CSF barrier.
What are ependymal cells?
Part of the tectum, this paired midbrain structure integrates visual information to coordinate reflexive head and eye movements toward stimuli.
What is the superior colliculus?
This rare genetic disorder, caused by a CAG trinucleotide repeat expansion in the HTT gene, leads to chorea, psychiatric symptoms, and neurodegeneration.
What is Huntington’s disease?
This K-pop group shares its name with a luminous optical effect seen in gemstones, but spells it with a “K” instead of a “C.”
What is KATSEYE
This mixed cranial nerve has three major branches—ophthalmic, maxillary, and mandibular—and provides facial sensation and chewing.
What is the trigeminal nerve? (V)
Essential for saltatory conduction, these glial cells form multilayered myelin sheaths in the CNS; their autoimmune destruction leads to conduction block, inflammatory plaques, and the hallmark sclerosis seen in MS.
What are oligodendrocytes?
These sympathetic nerves arise from spinal segments T1–T5 and accelerate heart rate and contractility.
What are the cardiac sympathetic nerves?
This famous Nobel-winning technique, developed in 1971, allows direct measurement of ionic currents at the level of single ion channels.
What is the patch-clamp technique?
This social-media personality and reality-TV figure finished second in Season 34 of Dancing with the Stars with Val Chmerkovskiy, narrowly losing the Mirrorball Trophy to Robert Irwin despite earning multiple perfect scores.
Who is Alix Earle?
