Study Notes
Musculoskeletal System Overview
- The musculoskeletal system encompasses the muscles and skeleton.
- It includes muscles, bones, joints, and related structures.
- Orthopedics is the medical branch focusing on preventing and correcting musculoskeletal deformities and diseases.
Major Bones of the Body
- Cranium: Skull
- Costa: Rib
- Sternum: Breastbone
- Spine: Backbone
- Vertebrae: Spinal bones (cervical, thoracic, lumbar, sacrum, coccyx).
- Clavicle: Collarbone
- Scapula: Shoulder blade
- Humerus: Upper arm bone
- Radius & Ulna: Forearm bones
- Carpals: Wrist bones
- Metacarpals: Hand bones
- Phalanges: Finger bones
- Ilium, Ischium, Pubis: Pelvic bones
- Femur: Thigh bone
- Patella: Knee cap
- Tibia & Fibula: Lower leg bones
- Tarsals: Ankle bones
- Calcaneus: Heel bone
- Metatarsals: Foot bones
- Phalanges: Toes
Specialized Tissues
- Cartilage: Dense connective tissue
- Chondral: Pertaining to cartilage
-
Muscles: Composed of cells (fibers)
- Cardiac: Heart muscle
- Smooth: Involuntary muscles (internal organs)
- Skeletal: Voluntary muscles (e.g., abductors, adductors)
- Fascia: Fibrous membrane supporting and separating muscles
- Tendon: Strong fibrous tissue attaching muscles to bones
Joints & Movements
- Articulation/Joint: Union point between two or more bones.
- Synovial Joints: Joints with cavities between articulating bones
- Synovium: Membrane surrounding cartilage in synovial joints
- Bursae: Fluid-filled sacs cushioning joints during movement
- Extension: Straightening a limb
- Flexion: Bending a limb
- Rotation: Bone movement around its axis
Musculoskeletal Disorders
- Fibromyalgia: Non-articular pain (torso, extremities, face)
- Myofibrosis: Tissue replacement with fibrous tissue
- Dislocation: Bone displacement from joint
- Fracture (fx): Bone breaking
- Sprain: Joint injury
- Myocele/fascial hernia: Muscle protruding through covering
- Tendonitis: Tendon inflammation
- Herniated Disc: Ruptured disc between vertebrae
- Para/plegia: Paralysis (lower body or both hands, legs)
- Quadriplegia/tetraplegia: Paralysis (all four limbs)
- Paresis: Motor weakness or partial paralysis
- Para/tetraparesis: Partial paralysis (lower limbs or all limbs)
- Cellulitis: Deep subcutaneous tissue inflammation
- Osteitis: Bone inflammation
- Osteochondritis: Inflammation of bones and cartilage
- Sarcomas: Cancers arising from connective tissue
- Chondrosarcoma: Malignant tumor of cartilage
- Fibrosarcoma: Malignant tumor of fibrous tissue
- Leukemia: Unextrolled/Unrestrained growth of certain blood cells' (leukocytes).
