Musculoskeletal & Types of Bone Cell - Lecture Notes

MUSCULOSKELETAL MUSCLES For movement Leverything moving → muscle Cardiac Pump blood ↳ myocardium 2.Smooth: visceral (Internal) + Involuntary La blood vessels, uterus, gut, bronchus 9. Skeletal: attached to Bones = voluntary Tendon muscle Bone (if Ab Muscle x move) Ligament bone bone (if Ab Dislocation) Pull" shorten=activity elongate: Resting ✓ Nerve Impulse = ↑ Movement permanent damage 4 Brain ما SC (Reflexes) } if Damage: Paralysis (-plegia) • IF Damage to muscle can regen. Blood Supply→Arteries = 102 4102=Tactivity 102=Jactivity Tactivity=102 Anaerobic Metabolism Heat Application Pyruvic Acid Lactic Acid Cramps vasodilate Fascia Muscle Membrane Muscle ↑ Pressure = ↓ circulation flers Muscle F Blood SKELETAL = 206 in adult 1. Long: movement + support → Femur, Tibia, Fibula, Humerus, Radius, Ulna, Phalanges Yellow Bone Marrow (Fats) Lo synthesis of vit. ADEK (fat-soluble → Liver) 2. Short: movement + support → Carpal, Tarsal ↳ Bone Marrow 3. Irregular: protection → Face, vertebra L unique 4. Flat: protection → Skull, Sternum, Ribs, Iliac Crest Red Bone Marrow = Hematopoiesis (Blood Cell Formation) L↳ RBC, WBC, platelets • Bone Marrow Aspiration: check for Ab in Blood Iliac Crest Thin Figure: Payat if specified Posterior Iliac Crest: aspirate Overweight: Ang Mataba Anterior Iliac Crest: aspirate TYPES OF BONE CELL 1. Osteoblasts: Bone Formation L↳ Matrix: Soft Milky Substances +Hardening Materials: Calcium + Phosphorus = Matured Bone ✓Ossified Ca: Bone is elastic ✓Calcified Ca: ✓ Fracture Estrogen (40-45-↓↓) ↓ Osteoblast *↓↓= ↓ Osteoblast Menopause ↑↑ Vit. D: ↑ Absorption of Ca in GI Liver (Fats): if ↑ fat in diet → get in yellow bone marrow
