Axial and Appendicular Skeletal System

Identify the function of the Axial skeletal structure.

• Locomotion

• Movement

• Protection

• Stature

We are composed of one skeleton that can be divided into two major regions, the axial and appendicular skeleton. Identify the structures that make up the axial skeleton,

• talus, calcaneus, navicular, cuboid, and cuneiform

• limbs and girdles

• skull, vertebrae, ribs and sternum

• hands, arms and shoulder girdle

Identify the bones NOT identified as Appendicular bones

• 26 bones in the vertebral column (24 vertebrae, the sacrum, and the coccyx)

• Left and right clavicle (2) and scapula (2).

• Arms and forearms (6 bones) - Left and right humerus (2) (arm), ulna (2) and radius (2) (forearm).

• Pectoral girdles (4 bones)

Identify a function of the axial skeleton

• allows for movement of the wrist and hand

• protects nerves and blood vessels at the elbos

• supports the trunk of the body

• allows for movement of the foot and ankle

Correctly complete this statement: The axial skeleton...

• consists of 126 bones.

• forms the vertical axis of the body.

• includes all bones of the body an trunk.

• includes only the bones of the lower limbs,

Identify the bone of the brain case.

• parietal bone.

• zygomatic bone.

• maxillary bone.

• lacrimal bone

Identify bones in human hand

• carpal, metacarpal, phalanges

• humerus, radial, ulna

• metatarsal, tarsals, phalanges

• femur, patella, tibia, fibula

Identify any of the 126 Appendicular Bones

• Humerus, Radius, Ulna, Carpals, Metacarpals, Phalanges,

• cranial, sternum, thorax, ossicles

• metacarpals, phalanges, sacrum, coccyx

• hyoid, humerus, sacrum, sternum

Identify the function(s) of the axial skeleton

• to provide support and protection for the brain, the spinal cord, and the organs in the ventral body cavity

• to support core of limbs

• to provides a surface for the attachment of muscles that move the head, neck, and trunk

• to performs respiratory movements

The appendicular skeleton consists of the limbs and girdles. Identify the girdles that are matched correctly to attached limbs.

• pelvic girdle is the attachment point for our thigh bone

• pectoral girdle is formed by the clavicle and scapula

• pectoral girdle serves as the attachment point for humerus and consists of ilium, icshium, and pubis

• pelvic girdle is the attachment point for femur
