Anatomy and Physiology 1.1a Flashcards
Structure of Ligament?
Tough band of slightly elastic connective tissue
Function of Ligament?
Connects bone to bone and stabilises joints
Structure of Synovial Fluid?
Lubricating liquid contained within the joint cavity
Function of Synovial Fluid?
Reduces friction and nourishes articular cartilage
Structure of Cartilage?
Smooth tissue which covers the surface articulating bones
Function of Cartilage?
Absorbs shock and allows friction-free movement
Structure of Capsule?
A fibrous sac with inner synovial membrane
Function of Capsule?
Encloses and strengthens the joint secreting synovial fluid
Three Planes of Movement?
Saggital, Frontal and Transverse
Saggital Plane?
Divides the body into left and right
Frontal Plane?
Divides the body into anterior/posterior (back/front)
Transverse Plane?
Divides body into upper and lower
Movements in Saggital Plane?
Flexion
Extension
Dorsi Flexion
Plantar Flexion
Movements in Frontal Plane?
Abduction
Adduction
Movements in Transverse Plane?
Horizontal extension
Horizontal flexion
Rotation
Ball and Socket Joint?
Shoulder and Hip
Hinge Joint?
Elbow, Knee and Ankle
Condyloid Joint?
Wrist
Saggital Movement at Ball and Socket?
Flexion and Extension
Frontal Movement at Ball and Socket Joint?
Abduction and Adduction
