Pterygopalatine fossa

Optional reading Moore, Clinically Oriented Anatomy, 9th ed., Pterygopalatine fossa section through The bottom line: Pterygopalatine fossa. The pterygopalatine fossa (PPF) is a small, bilateral bony space immediately behind the maxilla. Shaped like an inverted teardrop, it is about the size of a thumbnail. Bony borders Anterior: Posterior surface of maxilla. Posterior: Anterior surface of […]

Root of the neck

Optional reading Moore, Clinically Oriented Anatomy, 9th ed., Deep structures of neck section through Nerves in root of neck. The root of the neck (base of the neck, cervicothoracic region) is important because it is the region of continuity between the neck and thorax, and the neck and upper limbs. It can be somewhat confusing […]

Additional antiarrhythmics

So far, this module has covered high-yield antiarrhythmic medications by historical Singh Vaughan-Williams classification. There are other antiarrhythmics of note that will be covered now. Adenosine Adenosine binds to A1 adenosine receptors in the AV node (Gi‑coupled). Gi inhibits adenylyl cyclase → ↓ cAMP → reduced L‑type Ca²⁺ channel activity. This leads to: Slowed AV nodal conduction Increased […]
