  1. The Musculoskeletal system

  2. A) Bones • 1. Name of common bones (dividing our skeleton): • Head • Thorax • Spinal cord • Upper limbs • Lower limbs

  3. A) Bones • 2. Types: • Long bones • Found mostly in lower and upper limbs • Short bones • Found mostly in the wrists and ankles • Flat bones • E.g. skull, ribs, sternum, shoulder bone • Irregular bones • E.g. vertabrae

  4. A) Bones • 3. Function: • Support, insures posture • Protects internal organs • Ensures motion (working with muscles they act as levers) • Storage of necessary fat and minerals (calcium) • Production of red blood cells by the bone marrow (most often foun din long bones)

  5. A) Bones • Name of commonbones: • Vertabrea • Ribs • Femur • Tibia • Fibula • Radius • Ulna • Collarbone (clavicle) • Humerus • Carpals • Tarsals • Patella • Sternum

  6. B) Joints a) Definition: • place where two or more bones join b) Function: • Can allow for mobility (tendons attach bones to muscles) • Can link bones together (with ligaments)

  7. B) Joints c) Types of joints thatallowmobility (synovial joints): • Pivot Joint • allows for rotation (base of the skull) • Hinge joint • allows to bend in 1 direction(elbows and knees) • Gliding joint • allowsbones to slide on one another(vertabrea) • Ball and socket • allows for mostmobility(hip and shoulder) • Saddle Joint • allows 2 types of motion (thumbs) • Conyloid Joint • Fingers and toes

  8. B) Joints c) Types: • Pivot Joint • Hinge joint • Gliding joint • Ball and socket • Saddle Joint • Conyloid Joint

  9. d) Types of motions: • Flexion (decreasing the angle between two bones) • Extension (increasing the angle between two bones) • Abduction (limbs moving away from the body) • Adduction (limbs moving towards the body) • Rotation (turning around an axis)

  10. C) Muscles a) Whatisitreally? • Soft tissue made of cellsthatcontainprotein filaments thatcan change the cell’sshape b) Function: • Allows for motion • Producesheat

  11. C) Muscles c) Type of muscles: • Smooth: • Muscles surrounding internal organs • Are not voluntary • Striated muscles • Skeletal • Muscles anchored to the skeleton • Are voluntary • Cardiac • Muscles controlling the heart

  12. Team work d) Muscles working together: • Antagonistic muscles • Muscles can only pull cannot push back • Need another muscle to pull the limb back to its original position • Bicep/tricep
