Feeling Nervous?
Woah there sea horse! This structure within the limbic system is critical for learning and memory, and is the only consistently known site of neurogenesis in adulthood.
What is the hippocampus?
This structure, the muscle cell membrane, is composed of three layers: a plasma membrane, satellite cells, and a basement membrane.
What is the sarcolemma?
Damage to this region of the cerebrum would result in challenges processing visual information.
What is the occipital lobe?
Cerebral spinal fluid is formed by these in the lateral, third and fourth ventricles, a structure made of pia mater, a capillary bed, and ependymal cells.
What is choroid plexus?
This nuclei of the hypothalmus is associated with feeding reflex, and the feeling of satiety.
What are the mammilary bodies?
This type of glial cell mylenates neurons in the CNS.
What are oligodendricytes?
A fascicle, or bundle of muscle fibers, is wrapped in this connective tissue layer.
What is perimysium?
This structure of the diencephalon contains the pineal gland, which releases melatonin, which assists in regulating day/night cycles.
What is the epithalmus?
This artery directly supplies blood to the frontal and parietal lobes of the brain.
What is the anterior cerebral artery?
Oh no, I’m feeling attached! Thanks to this nuclei of the hypothalamus, which secretes oxytocin, a critical hormone in pair bonding and uterine contraction.
What are the paraventricular nuclei?
The roots of the spinal cord after L1 form this structure, so named due to its resemblance to a horse’s tail.
What is the cauda equine?
This structure acts as a channel for electrical excitement, transmitting the action potential from the sarcolemma to the sarcoplasmic reticulum.
What is a T Tubule?
One finds the pneumotaxic center and apneustic centers within this structure of the brain.
What is the pons?
In the venus drainage system, blood from the superior saggital sinus and the inferior saggital sinus (via the straight sinus) converge here.
What is the confluence of the sinuses?
These two nuclei make up the lentiform, or lens shaped, nuclei. They assist in motor learning, and adjusting muscle tone -- just name one, or both, for twice the points.
What is putamen (stages) and/or globus pallidus (muscle tone)?
Beware the low blow! This ascending pathway conveys information about deep pressure and crude touch.
What is the anterior spinothalamic tract?
This component of the thin filament covers actin to regulate cross-bridge cycling.
What is tropomyosin?
This structure of the cerebellum forms tracts of mylenated axons that allow for communication across the CNS.
What are the peduncles?
This type of fiber allows for communication between each hemisphere of the brain -- the corpus collusum being a central example.
What are commissural fibers?
This nucleus within the basal nuclei group does not initiate movement, but determines rhythm and pattern.
What is the caudate nuclei?
This descending pathway crosses low to send conscious motor control information to axial muscles.
What is the anterior corticospinal tract?
When a sarcomere contracts, this area disappears.
What is the H band/zone?
This region of the midbrain inhibits involuntary movements -- disorders in this region are often associated with Parkinson’s disease.
What is the substantia nigra?
This extention of the meningeal layer of the dura mater makes a space between the cerebrum and the cerebellum.
What is the tentorum cerebelli?
This nuclei of the thalamus processes auditory information before sending it on to the primary auditory center in the temporal lobe.
What is the medial geniculate nucleus?
