Skeletal bone, names and locations

The different bones of the skeleton

Knowing the various bones and their specific locations within the body allows you to identify specific landmarks for the various muscle attachments. The skeleton can be split between the axial skeleton highlighted in blue, and the appendicular skeleton which is not highlighted. The axial skeleton is the main frame or axis of the skeleton structure with the appendicular skeleton consisting of the appendages which attach to the axial skeleton, the appendicular skeleton is duplicated on both the right and left sides of the skeleton.

Here we have a list of all of the skeletal bones in the human body with the specific amount of bones (in brackets) for each skeletal section.

The axial skeleton is the main frame or axis of the skeleton structure and includes the cranium or skull (22), the spine, which is comprised of the cervical (7), thoracic (12), lumbar (5), sacral (5) and coccygeal (4) vertebra. The thorax which includes 12 pairs of ribs (24) or costals and the sternum (1) or breastbone.

The appendicular skeleton consists of the appendages which attach to the axial skeleton, the appendicular skeleton is duplicated on both right and left sides of the skeleton and includes the shoulder girdle which comprises of both the clavicle (2) and scapula (2) and locates the upper limbs.

The upper limbs comprise the humerus (2) of the upper arm, the radius (2) and ulna (2) of the lower arm, and the hands which comprises of the carpals (16) in the wrist, metacarpals (10) in the palm and thumb and the phalanges (28) of the fingers and ends of the thumbs.

We then have the pelvic girdle which comprises of the ilium (2) at the top, ischium (2) or sitting bones at the bottom & pubis (2) at the front of the pelvis, these bones are all fused together and joined to the sacral spine.

The pelvic girdle locates the lower limbs which includes the femur (2) and patella (2) of the upper leg, and the tibia (2) and fibula (2) of the lower leg. There appendicular skeleton is completed with the tarsals (14) forming each ankle, metatarsals (10) forming each foot and phalanges (28) forming the toes.
