This acetylcholinesterase inhibitor is used chronically for myasthenia gravis and can cause excessive salivation and muscle twitching.
What is Pyridostigmine?
The trapezoid body is where the decussation of this specific cranial nerve fiber occurs.
What is the vestibulocochlear (auditory) fiber?
In Wilson's disease, this specific transporter enzyme is mutated, preventing copper from being incorporated into apoceruloplasmin.
What is ATP7B?
This diagnostic finding, characterized by a patched mosaic pattern and a "saw-toothed" appearance of the duodenal folds , is typical of this autoimmune malabsorption syndrome.
What is Celiac Disease (Gluten Enteropathy)?
This patient presentation includes a "droopy right eyelid," slurred speech, and an anterior mediastinal mass displacing the superior vena cava.
What is Myasthenia Gravis (associated with a Thymoma)?
This ACE inhibitor lowers blood pressure by blocking conversion of angiotensin I to angiotensin II and may cause orthostatic hypotension in the dental chair.
What is Lisinopril/Quinapril?
These three sensations are received and transmitted through the medial lemniscus pathway.
What are proprioception, vibration, and discriminatory touch?
This is the primary anatomical difference in where autoantibodies attack the neuromuscular junction in Myasthenia Gravis versus Lambert-Eaton syndrome.
What is postsynaptic targeting (MG) versus presynaptic targeting (LEMS)?
This gastrointestinal hormone is secreted by the I cells of the duodenum and jejunum specifically in response to monoglycerides and fatty acids.
What is CCK (Cholecystokinin)?
In the case of Nick Watters, he presented with a sudden onset of dizziness, uncontrollable hiccups, and a tendency to fall to his left—classic signs of a syndrome caused by an acute infarct in the left dorsolateral medulla.
What is Wallenberg Syndrome?
This platinum-based chemotherapeutic agent crosslinks DNA, causes bone marrow suppression, and increases petechiae risk.
What is Cisplatin?
The reticulospinal tract has two sections—the pontine and the medullary—which respectively focus on these two opposing motor actions.
What are extension (pontine) and flexion (medullary)?
This specific term describes the breakdown of the blood-brain barrier that allows fluid to leak into the extracellular space around a Glioblastoma.
What is vasogenic edema?
In the absorption of carbohydrates, this specific transporter is responsible for the uptake of fructose across the apical membrane of enterocytes.
What is GLUT5?
A lesion in the Angular Gyrus of the dominant hemisphere results in this specific syndrome, characterized by the clinical tetrad of agraphia, acalculia, finger agnosia, and left-right disorientation.
What is Gerstmann Syndrome?
This drug used for Wilson’s disease chelates copper, requires zinc supplementation, and may cause anemia and thrombocytopenia, increasing bleeding risk during extractions.
What is Trientine?
This cerebellar nucleus is where the vermis synapses to augment the movement of the axial part of the body.
What is the fastigial nucleus?
This condition involves a fluid-filled cavity within the spinal cord that specifically destroys the Anterior White Commissure, leading to a bilateral, "cape-like" loss of pain and temperature while sparing fine touch and proprioception.
What is Syringomyelia?
Zollinger-Ellison syndrome specifically leads to steatorrhea (fat in the stool) through this exact mechanism affecting enzymatic digestion.
What is low luminal pH inactivating pancreatic lipase?
This is a common malignant brain tumor in children; it typically arises in the cerebellum, features Homer Wright rosettes, and can lead to hydrocephalus by compressing the fourth ventricle.
What is Medulloblastoma?
This meglitinide stimulates pancreatic insulin release and carries a risk of hypoglycemia during long dental procedures.
What is Repaglinide?
Choreiform movements are the result of lesions in this part of the brain.
What is the corpus striatum?
A biopsy of a Grade 4 astrocytoma (glioblastoma multiforme) is characterized by pleomorphic cells, mitotic figures, and this specific histological feature describing areas of tissue death surrounded by tumor cells.
What is necrosis with pseudopalisading (or pseudopalisading vascular proliferation)?
After digestion, long-chain fatty acids and monoglycerides form into triglycerides and combine with proteins inside the Golgi apparatus to form these, which are then extruded into the lacteals.
What are chylomicrons?
This specific type of spinal cord lesion at T4 caused George Skehan's Brown-Séquard syndrome symptoms, characterized pathologically by whorls and psammoma bodies.
What is a Meningioma?
