Lesions outside the thecal sac are categorized as extradural lesions. Remember that everything that isn’t in the thecal sac is extradural, including discs, bones, nerves, and blood vessels.
Mnemonic: CAT 1. Coronary sinus (50%): Drains blood from left side of heart → Thebesian valve → Right Atrium 2. Anterior cardiac veins (20%): Drain blood from right side of heart → Right Atrium 3. Thebesian veins/Venae cordis minimi (30%): Drain deoxygenated blood from endocardium and myocardium → Respective chamber…
11-cis-retinal combines with opsin protein to form rhodopsin. Light stimulates conversion of rhodopsin bound 11-cis-retinal to all-trans-retinol (all-trans-retinol is transported from photoreceptor cells to retinal pigment epithelium), which subsequently dissociates from opsin (bleaching), leading to membrane depolarization and initiation of action potential in photoreceptors in the neural retina. Once in…
