Skeletal System Flashcards
Fundtions of skeleton for sport
Storing minerals Blood cell protection Joints for movement Muscle attachment Protection to vital organs
Cartilage
A firm connective tissue
Ossification
The process of development from cartilage to bone
Somatotype
Body shape or type
Classification of bones (4)
Long bones, short bones, flat bones, irregular bones
Cervical vertebrae
7 parts to it
Thoracic vertebrae
Twelve parts
Lumbar vertebrae
Five parts to it
Sacral vertebrae
Five fused
Coccygeal vertebrae
Four fused
Long bones use?
Generate movement
e.g. phalanges
Short bone use?
Weight bearing
e.g. Carpals
Flat bones use?
Protect organs or offer a good surface for muscles to attach to
e.g. Scapular
Irregular bones?
Protection
e.g. maxilla
Joints
A place where two or more bones meet
4 types of joints are…
Pivot
Hinge
Ball and socket
Condyloid
Pivot joints function
Allow bones to rotate e.g. wrist elbow and neck
Hinge joints function
Allows backward and forward motion e.g. knee, elbow, ankle
Ball and socket function
Rotation e.g. hip and shoulder
Condyloid function
Movement such as flexion, extension, addiction, abduction
Flexion
Decreasing the angle at a joint e.g. shoulder, hip,elbow
Extension
Increasing the angle at a joint
Adduction
Moving towards the midline of the body
Abduction
Moving away from the midline of the body
Plantar flexion
Movement of the foot downward towards the sole
Dorsi flexion
Backward flexion of the foot
