Skeletal System Flashcards
(22 cards)
What is the shape/support function of the skeleton during performances?
Ligaments and tendons provides stability at joints and gives the body its upright shape. It can influence your potential to be an elite performer
What is the movement function of the skeleton during performance?
Freely moveable or synovial joints enable a wide range of movements
What is the protection function of the skeleton during performance?
Skeleton provides protection for vital organs e.g. skull protects brain
What is the blood cell production function of the skeleton during performance?
Red blood cells made in red marrow of bones. They are important during exams they carry oxygen to muscles and remove CO2. White blood cells protect body from infection and platelets for clots and stop bleeding
What is the mineral storage function of the skeleton during performance?
Bone acts as a storage for excess calcium, phosphorus and iron
What is a synovial joint?
They are freely moveable which means they are essential for sport and physical activity
What is the function of a synovial capsule?
Reduce friction between bones in your joints
What is the function of the synovial membrane?
Protect the joints they surround
What is the function of the synovial fluid?
Reduce friction between the articular cartilages of synovial joints during movement
What is the function of the Bursar?
Act as a cushion that absorbs pressure present in some joints
What is the function of the cartilage?
Helps prevent bones from rubbing together
What is the function of your ligaments?
Stabilise the joint. Attach one bone to another
What is the function of your tendons?
Tough bands of connective tissue, attach skeletal muscles to bones.
Long term effects of exercise and optimal training on the skeletal system (skeletal tissue)
They become stronger and denser as a result of an increase in calcium deposits and callogen fibres
Long term effects of exercise and optimal training on the skeletal system (cartilage)
They become thicker and stronger and provide increased protection and cushioning
Long term effects of exercise and optimal training on the skeletal system (tendons)
They become thicker and stronger and can withstand greater forces when muscles pull on them
Type of joint and movement of hip and shoulder
Ball and socket and circumduction, abduction/adduction
Type of joint and movement of wrist
Condyloid and flexion/extension, abduction/adduction
Type of joint and movement of thumb
Saddle and flexion/extension, abduction/adduction
Type of joint and movement of neck
Pivot and rotation
Type of joint and movement of knee/elbow
Hinge and flexion/extension
Type of joint and movement of ankle
Plane and gliding in all directions
