Joint Movements and Connective Tissues

This page focuses on the various types of joint movements and the connective tissues that support the skeletal system.

Joint Movements

Different joint movements allow for a wide range of motion in sports and everyday activities:

  1. Flexion: Closing a joint e.g.,preparingtoshootinnetballe.g., preparing to shoot in netball
  2. Extension: Opening a joint e.g.,kickingafootballe.g., kicking a football
  3. Adduction: Moving towards an imaginary center line e.g.,swingingagolfclube.g., swinging a golf club
  4. Abduction: Moving away from an imaginary center line e.g.,preparingtothrowadiscuse.g., preparing to throw a discus
  5. Rotation: Clockwise or anticlockwise movement of a limb e.g.,shouldermovementinatennistopspinforehande.g., shoulder movement in a tennis topspin forehand
  6. Circumduction: Circular motion of a limb, hand, or foot e.g.,bowlingacricketballoverarme.g., bowling a cricket ball overarm
  7. Plantar flexion: Extension at the ankle e.g.,pointingtoesingymnasticse.g., pointing toes in gymnastics
  8. Dorsiflexion: Flexion at the ankle e.g.,liftingtoesingymnasticse.g., lifting toes in gymnastics

Definition: Circumduction - A circular movement combining flexion, extension, adduction, and abduction at a joint.

Types of Joints

The page mentions two types of synovial joints:

  1. Ball and socket joint
  2. Hinge joint

Connective Tissues

Connective tissues play crucial roles in supporting the skeletal system:

  1. Ligaments: Connect bone to bone, restricting joint movement and maintaining skeletal stability.
  2. Tendons: Attach muscles to bones or other muscles, allowing for bone movement during muscle contraction.
  3. Cartilage: Acts as a cushion between bones, preventing friction damage during joint movement and aiding joint stability.

Highlight: Connective tissues are essential for joint health and proper movement in athletics.

Synovial Joints and Muscular System

This page delves into the structure of synovial joints and provides an overview of the muscular system's role in movement.

Synovial Joints

A synovial joint allows for a wide range of movement and consists of several components:

  1. Synovial fluid: Lubricates the joint, reduces friction, supplies nutrients, and removes waste products.
  2. Synovial membrane: Contains and releases synovial fluid.
  3. Articular cartilage: Prevents bones from rubbing together and acts as a shock absorber.
  4. Joint capsule: Surrounds, protects, and stabilizes the joint.
  5. Ligaments: Join bone to bone.
  6. Bursae: Fluid-filled sacs that cushion between tendons and bones, reducing friction.

Vocabulary: Bursae - Small, fluid-filled sacs that act as cushions between bones, tendons, and muscles around joints.

Muscular System

The page outlines various muscles and their functions in relation to joint movements:

  1. Biceps: Flexion at the elbow e.g.,curlingweightse.g., curling weights
  2. Triceps: Extension at the elbow e.g.,jumpshotinbasketballe.g., jump shot in basketball
  3. Pectorals: Adduction and horizontal flexion at the shoulder e.g.,forehanddriveintennise.g., forehand drive in tennis
  4. Latissimus dorsi: Extension, adduction, or rotation at the shoulder e.g.,butterflystrokeinswimminge.g., butterfly stroke in swimming
  5. Deltoid: Flexion, extension, abduction, or circumduction at the shoulder e.g.,frontcrawlinswimminge.g., front crawl in swimming
  6. Rotator cuffs: Rotation and abduction at the shoulder
  7. Abdominals: Flexion at the waist e.g.,upwardphaseofasitupe.g., upward phase of a sit-up
  8. Hip flexors: Flexion of the leg at the hip e.g.,liftingthekneewhensprintinge.g., lifting the knee when sprinting
  9. Gluteals: Extension, rotation, and abduction of the leg at the hip e.g.,pushingthebodyforwardwhenrunninge.g., pushing the body forward when running
  10. Hamstrings: Flexion at the knee e.g.,bringingthefootbackbeforekickingafootballe.g., bringing the foot back before kicking a football

The Skeletal System: Functions and Types of Bones

The skeletal system plays a vital role in human anatomy and athletic performance. This page covers the main functions of the skeletal system and the different types of bones found in the human body.

Functions of the Skeletal System

The skeletal system serves several essential functions:

  1. Support and Shape: The skeleton provides a rigid frame for the body, supporting soft tissues and aiding in posture, which is crucial for sports like gymnastics.
  2. Protection: Bones protect vital organs, reducing the risk of serious injury during physical activities.

Example: The skull protects the brain, allowing athletes to head a football or take punches in boxing without severe damage.

  1. Movement: Bones work with muscles and tendons to enable movement at joints, which is essential for athletic performance.
  2. Blood Cell Production: Bone marrow produces blood components, including red blood cells that transport oxygen to muscles during exercise.

Highlight: Athletes with higher blood cell counts may perform better due to increased oxygen delivery to muscles.

  1. Mineral Storage: Bones store minerals like calcium and phosphorus, which contribute to bone strength and muscle function.

Types of Bones

The human body contains several types of bones, each with specific characteristics and functions:

  1. Long bones: Longer than they are wide, used for larger gross movements.
  2. Short bones: Approximately as wide as they are long, used for smaller, fine movements.
  3. Flat bones: Strong, flat plates that protect internal organs and provide surfaces for muscle attachment.
  4. Irregular bones: Bones that don't fit into other categories.
  5. Sesamoid bones: Embedded in tendons, such as the patella kneecapkneecap.

Vocabulary: Patella - The kneecap, a sesamoid bone embedded in the quadriceps tendon.

The page also includes a diagram labeling various bones in the human body, including the cranium, scapula, humerus, and femur.
