Anatomy:in Depth Summary With Details

Anatomy: In-Depth Summary1. Musculoskeletal SystemBones: Axial (skull, vertebrae, ribs) & Appendicular (limbs, girdles). Joints: Synovial (freely movable), Fibrous, Cartilaginous. Muscles: Origin, Insertion, Action, Innervation. Mnemonic (Carpal bones): Some Lovers Try Positions That They Cant Handle Scaphoid, Lunate, Triquetrum, Pisiform, T rapezium, Trapezoid, Capitate, Hamate. Diagrams: Skeleton overview , major muscle groups with action arrows. Clinical correlation: Fracture sites (Colles, femoral neck), common tendon injuries.2. Nervous SystemCNS: Brain (cerebrum, cerebellum, brainstem), Spinal cord. PNS: Cranial & Spinal nerves. Functional divisions: Sensory (afferent), Motor (efferent). Cranial nerves: I-XII; Mnemonic: Oh, Oh, Oh, To Touch And Feel V ery Good V elvet, AH! Autonomic NS: Sympathetic (fight/flight), Parasympathetic (rest/digest). Diagram: Brain lobes + functions, spinal cord segments + reflex arcs. Clinical correlation: Stroke syndromes (MCA infarct), peripheral neuropathies.3. Cardiovascular SystemHeart: Chambers, valves, conduction system (SA AV Bundle of His Purkinje). Mnemonic for heart sounds: S1 = AV closure, S2 = Semilunar closure. Blood vessels: Arteries (carry oxygenated blood except pulmonary), V eins (deoxygenated except pulmonary). Major arteries: Aorta Coronary , Carotid, Subclavian. Diagram: Heart cross-section, circulation loop. Clinical correlation: Myocardial infarction (LAD), hypertension effects on vessels.4. Respiratory SystemUpper: Nose, pharynx, larynx. Lower: T rachea, bronchi, bronchioles, alveoli. Mechanics: Ventilation = Boyle s law,
