Botulism & Anti-cholinergic vs Cholinergic Toxicity, Clostridium Botulinum/USMLE Step 1/Microbiology
Botulinum toxin blocks the presynaptic exocytosis of ACh vesicles, causing impaired muscarinic and nicotinic neurotransmission. It characteristically presents as a symmetric descending paralysis that manifests with cranial nerve abnormalities, often following consumption of home-canned foods.

Tetanus & Clostridium tetani, Pathophysiology, Trismus, Risus Sardonicus, Microbiology, USMLE Step 1
มุมมอง 5419 ชั่วโมงที่ผ่านมา
Tetanus is caused by infection with toxigenic strains of the anaerobic bacterium Clostridium tetani. Transmission typically occurs when spores are inoculated into the skin via a puncture wound. The bacteria germinate, replicate locally, and elaborate tetano-spasmin; (tetanus toxoid). The toxin spreads in a retrograde fashion through the lower motor neurons to the spinal cord, where it blocks in...
Anti-seizure Medication for Status Epilepticus, Anticonvulsant/Antiepileptic - Pharmacology, USMLE
มุมมอง 179วันที่ผ่านมา
Antiseizure medications inhibit neural activity (decrease neural excitation, increase neural inhibition); and increase the seizure threshold by interacting with specific receptors and ion channels. Mechanisms of common anti-seizure medications 1. Benzodiazepines and Phenobarbital increase gamma-aminobutyric acid (GABA) action 2. Levetiracetam Inhibits vesicle fusion by binding Synaptic vesicle ...

Normal Pressure Hydrocephalus Pathophysiology & Micturition Reflex, USMLE STEP 1, UWorld Case Study
มุมมอง 4314 วันที่ผ่านมา
Normal pressure hydrocephalus occurs due to decreased cerebrospinal fluid absorption, resulting in ventriculo-megaly with normal intracranial pressure. This causes stretching of the descending cortical fibers (corona radiata) from the frontal lobe and contributes to the classic triad of symptoms (that is, dementia, gait abnormalities, urinary incontinence). Loss of cortical inhibition of the sa...

มุมมอง 7614 วันที่ผ่านมา
Tabes dorsalis, a late form of neurosyphilis, causes progressive degeneration of the dorsal columns and dorsal roots of the spinal cord. Manifestations include loss of proprioception and vibratory sensation, severe lancinating pains, and sensory ataxia (eg, wide-based gait, positive Romberg sign). Many patients also have Argyll Robertson pupils. Tabes dorsalis is characterized by a slow degener...
Kinesin vs Dynein - USMLE STEP 1, UWorld Question, Nervous System, Neurology
มุมมอง 6514 วันที่ผ่านมา
Kinesin is a microtubule-associated, ATP-powered motor protein that facilitates the anterograde transport of neurotransmitter-containing secretory vesicles down axons to synaptic terminals. In contrast, dyneins are motor proteins that move toward the minus end of a microtubule in retrograde transport.

Neisseria Meningitidis & Meningitis - USMLE STEP 1, UWorld Question, Nervous System, MBBS
มุมมอง 7121 วันที่ผ่านมา
Neisseria meningitidis is transmitted primarily by aerosolized droplets and subsequently colonizes the nasopharyngeal epithelium. Penetration of the epithelium can lead to bloodstream infection. Spread to the meninges occurs via transcellular penetration of the cerebral capillary endothelium or entry at the choroid plexus.

Bell's Palsy - Central vs Peripheral Facial Nerve Lesions, USMLE STEP 1, UWorld Nervous System, MBBS
มุมมอง 9421 วันที่ผ่านมา
The most common cause of acute unilateral upper and lower facial weakness is Bell palsy, an acute peripheral neuropathy of CN VII. Common findings include an inability to raise the eyebrow or close the eye, drooping of the mouth corner (with the mouth drawn to the unaffected side), and disappearance of the nasolabial fold. For most patients, partial or complete recovery occurs within 3-4 months...
Myasthenia Gravis - USMLE STEP 1, USMLE UWorld Question, MBBS
มุมมอง 60หลายเดือนก่อน
Myasthenia gravis is caused by circulating antibodies directed against acetylcholine receptors of the neuromuscular junction. Autoantibody binding leads to receptor degradation, producing fluctuating weakness that worsens throughout the day and most commonly affects the extraocular muscles (for example, ptosis, diplopia). Most patients have thymic abnormalities (for example, thymoma). CC BY-SA ...
