Walls of the Tympanic Cavity or Middle Ear This cavity is shaped like a narrow six-sided box that has convex medial and lateral walls. It has the shape of the biconcave lens in cross-section (like a red blood cell).   The Roof or Tegmental Wall This is formed by a thin plate of bone, called the tegmen tympani (L. tegmen, roof). It separates the tympanic cavity from the dura on the floor of middle cranial fossa. The tegmen tympani also …

Lamotrigine (Lamictal): newer; broad spectrum (for most seizure types) Mechanism: ↓ reactivation of Na channels (↑ refractory period, blocks high frequency cell firing) Side effects: dizziness, ataxia, fatigue, nausea, no significant drug interactions…

Periodontal Bone Grafts Bone grafting is a critical procedure in periodontal surgery, aimed at restoring lost bone and supporting the regeneration of periodontal tissues. 1. Bone Blend  Bone blend is a mixture of cortical or cancellous bone that is procured using a trephine or rongeurs, placed in an amalgam capsule, and triturated to achieve a slushy osseous mass. This technique allows for the creation of smaller particle sizes, which enhances resor…

Step 1.  Acyl-CoA Dehydrogenase catalyzes oxidation of the fatty acid moiety of acyl-CoA, to produce a double bond between carbon atoms 2 and 3. There are different Acyl-CoA Dehydrogenases for short (4-6 C), medium (6-10 C), long and very long (12-18 C) chain fatty acids. Very Long Chain Acyl-CoA Dehydrogenase is bound to the inner mitochondrial membrane. The others are soluble enzymes located in the mitochondrial matrix. FAD is the prosthetic group …
