The Musculoskeletal System And Analysis Of Movement Flashcards
The shoulder
Humorous and scapula
Ball and socket joint
Elbow
Humerus radius and ulna
Hinge joint
Hip
Pelvis and femur
Ball and socket
Knee
Femur and tibia
Hinge
Ankle
Talus tibia and fibula
Hinge joint
What are the two types of isotonic muscular contraction
Concentric and eccentric
Concentric muscle contraction
The normal contraction
When a muscle shortens Under tension
For example the upwards phase of a squat
Eccentric
When a muscle lengthens under tension or performs negative work and act like a break
For example the downwards phase of a squat
Isometric muscular contraction
When a muscle is under tension but there’s no visible movement
Flexion
Decreasing the joint angle
Extension
Increasing the joint angle
Hyper extension
Increasing joint between bones beyond 180°
Abduction
Moving away from the midline of the body
Addiction
Movement towards the midline of the body
Horizontal adduction
Movement of the joint from abduction and flexion
Horizontal abduction
Movement of the joint from flexion to abduction
Sagittal plane/ transverse axis
Movements that take place in the sagittal plane and around the transverse axis are flexion and extension
Eg a swing in tennis
Frontal plane and sagittal axis
Movements that take place in the frontal plane and around the sagittal access abduction and abduction
For example a star jump
Transverse plane/longitudinal axis
Movements that take place in the transverse plane and around the longitudinal axis a horizontal abduction and adduction
For example the shoulder as the athlete throws the discus
