Functions, types and location of muscles

View mindmap
  • Skeleton joints, muscles and tendons
    • Location of bones and joints
      • Ball and socket in hip and shoulders
      • Hinge joint in knees, elbows, ankles and wrists
    • Range of movement
      • Ball an dsocket can move 360 degrees
      • Hinge can move roughly 170 degrees vertically and cant bend horizontally
    • Ligaments, tendons and synovial fluid
      • Tendons attach muscles to the bones
      • Synovial fluids lubricate the joints for friction free movement
      • Ligaments hold the bones together and prevent dislocation
    • Functions, types and location of muscels
      • Hamstring - Back and top of the leg. Pulls to bend knee up and relaxes to let knee fall down
      • Gastrocnemius - Is below the hamstring on the back of the leg. It contracts to point the toes at the ankle and relaxes to let ankle point up
      • Quadriceps - At the top front of leg. Contract to pull the knee forward and relax to let knee get pulled back by the hamstring
      • Abdominals - Centre of torso on the front. Contract to pull the legs up to the body and relax to let the gluteus maximus pull the legs away
      • Biceps - Top of the arm on the front. Tenses to bend elbow up and relaxes to let triceps pull elbow straight
      • Pectorals - Top of torso at the front. Tenses to pull arms into the center line and relaxes to let latissimus dorsi pull arms away from the center line
      • Triceps - Top of the arm on the back. Tenses to pull the elbow straight and relaxes to let the biceps pull the elbow up
      • Latissimus Dorsi - Top of the torso on the back. Tenses to pull arms away from center line and relaxes to let pectorals pull them back in
      • Gluteus maximus - Lower waist on the back. Tenses to pull legs straight and relaxes to let the abdominals pull legs up
