Core 2-The Body in Motion. The skeletal System. Skeletal System. An anatomical reference system called directional terms is used to identify the location of bones.
The skeletal System
Frontal (Coronal) Plane
2. Appendicular skeleton-consists of the bones of the upper and lower limbs and the bony girdles that support them on the body trunk.
1. Long Bones- are hollow, tubular in shape and have along shaft. The ends of long bones form the articulating or connecting surfaces at joints.
- these bones can withstand heavy stress and are important in weight bearing.
- examples: humerus, femur, radius, tibia, ulna and phalanges.
2. Short Bones- are shaped like a cube and almost equal in length and width.
- examples: bones in the wrist (carpals) and ankle bones (tarsals)
3. Flat Bones- generally thin with a layer of spongy bone in their centre.
- they are usually broad in shape and have a smooth surface allowing a large area for muscle attachment.
-examples: scapula, cranial bones, sternum and ribs
4. Irregular Bones- complex shapes, for example vertebrae
5. Sesamoid Bones- this type of bone is small and found in special tissue called tendons, where there can be more than usual pressure applied.
- examples: the patella
