  1. Muscular SystemTypesof Joint Movement SHMD 139 11/02/2013

  2. Planes of the Body • Frontal Plane =

  3. Pg 9-11 Joints & Movement • Neck • Pivot joint. • Movement • Rotation: Limb moves in a circular movement towards the middle of the body. • Flexion: Occurs when the angle of a joint decreases. • Extension: Occurs the angle of a joint increases. • Lateral flexion & extension.

  4. Shoulder • Ball & Socket joint. • Movement • Circumduction:limb moves in a circle. • Rotation. • Abduction: Movement away from the midline of the body. • Adduction: Movement towards the midline of the body. • Horizontal adduction & abduction. • Flexion. • Extension. • Hyperextension: exaggerated extension motion.

  5. Elbow • Hinge joint. • Movement • Flexion. • Extension.

  6. Wrist • Condyloid joint. • Movement • Flexion. • Extension. • Adduction. • Abduction. • Circumduction. • Pronation: when the hand moves from an upward facing position to a downward facing position. • Supination: when the hand moves from a downward facing position to an upward facing position.

  7. Hip • Ball & Socket joint. • Movement • Circumduction. • Rotation. • Flexion. • Extension. • Adduction. • Abduction.

  8. Knee • Hinge joint. • Movement • Flexion. • Extension.

  9. Ankle • Synovial hinge joint. • Movement (Specific to ankle joint) • Plantarflexion: Foot moves away from the shin bone, and your toes will be pointing downward. • Dorsiflexion: foot moves toward the shin bone as if you are pulling your toes up. • Occurs at gliding joint between tarsals: • Inversion: Soles of the feet are facing each other. • Eversion: Soles of the feet are facing away from each other.

  10. Anterior Muscles Trapezius Deltoid Pectoralis Major Biceps Serratus Anterior Rectus Abdominus Abdominal Obliques Rectus Femoris Sartorius Vastus Lateralis Vastus Medialis Gastrocnemius Tibialis Anterior Soleus

  11. Posterior Muscles Trapezius Rhomboids Deltoids Triceps Latissimus Dorsi External Oblique Gluteus Maximus Biceps Femoris Gluteus Medius Semitensinosus Semimembranosus Gastrocnemius Soleus Achilles Tendon

  12. Tendons & Ligaments • Tendons: • Connects muscle to bone. • Carry force of muscle contraction to the bone. • Ligaments: • Connects bone to bone. • Act to give stability to joints.

  13. Definitions • Cartilage: Tough, fibrous connective tissue without nerves or blood supply that provides protection and support to joints, tubes, ends of long bones, and facial structures (e.g., ears and nose).

  14. Definitions • Bursa:small sacs of fluid that are located between bone & other moving structures i.e. muscles, skin, tendons. Bursa allows smooth gliding between structures, without friction.
