Skeletal system Flashcards
Axial Skeleton
There are 80 bones in axial skeleton including the skull, spine and rib cage
Appendicular Skeleton
There are 126 bones in the appendicular skeleton including appendages of the arms, legs, scapulae, clavicles and pelvis
Hyoid
Neck bone
Sternum
Chest bone
Vertebrae
Spine
Sacrum
Base of spine
Coccyx
Pelvis bone
Clavicle
Shoulder bone
Scapula
Shoulder blade, a flat, triangular-shaped bone located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.
Humerus
Upper arm bone
Radius
Lower arm bone (inner/proximal/thumb) Rotates around ulna
