Applied Anatomy and Physiology (pg 6-20) Flashcards
Cranium
Your head (skull)
Clavicle
Your collarbone (to the side of your neck)

Your shoulder blades (sits beside the rib cage)
Sternum
Breast bone (front and middle of rib cage)
Ribs
(Rib cage) protects your heart.
Spine
Backbone (runs along your whole back)
Humerus
(Upper arm) funny bone.
Ulna
(Forearm) bone closer to the inside of your body (thick)
Radius
(Forearm) bone further away from your body (thin)

(Wrist bone)

Functions of the skeletal system
Support- skeleton supports the body. Fe. A backbone enables us to stay upright
Movement - The skeleton has joints where tendons join muscle to bone, enables us to move
Protection- skeleton helps to protect delicate internal organs from injury
Blood production - blood cells produced in bone marrow, red cells transport oxygen and white protect the body.
Mineral storage- important minerals such as calcium and phosphorous, are stored in the body.
Long bones
Help translate the force generated by the skeletal muscle into mechanical leverage (movement), eg femur.
Flat bones
Help protect the body’s internal organs and with muscle attachment, eg.cranium and sternum.
Short bones
Help and provide support and stability with little movements (weight bearing) eg. Carpals and tarsals.
Irregular bones
Do not fall into any category but generally help with protection and support eg.vertebrae.
Ligaments
Connect bone to bone (keep joints stable)
Synovial fluid
Reduces friction at joints, allowing them to move freely
Tendons
Connect muscle to bone, allow movement.
Hinge joint
Provides movement in one plane for flexion and extension. Fe, flexion and extension at elbow when performing a pull up.
Pivot
Provides rotatory movement around a single axis for rotation. Fe, enables rotation of the neck when taking a breath whilst swimming.
Ball and socket
Provides 360° rotation and movement in all planes for flexion, extension, adduction abduction and rotation. Fe, enables rotation at the hip when hurdling.
Condyloid
Provides movement in two planes for flexion, extension, adduction and abduction. Fe. Enables extension and flexion at the wrist when dribbling (bouncing) a basketball.
Flexion
When angle at a joint decreases
