Skeletal System and Bone Tissue

The skeletal system consists of:

5 functions of the Skeletal System

of bones in the skeleton

Axial skeleton consists of:

Appendicular skeleton consists of:

5 classifications of bone shape

Bones longer than they are wide (e.g. femur)

Bones about as long as they are wide (e.g. carpals)

Bones which are slightly curved and flattened (e.g. scapula)

Bones whose shapes don’t fit into other categories (e.g. vertebrae)

Bones surrounded by connective tissue; no bone-to-bone connection (e.g. patella)

• Long shaft of a long bone • Contains medullary cavity • Made up entirely of compact bone

• Broadened end of a long bone • Made of cancellous (spongy) bone covered by compact bone • Covered in hyaline cartilage to form the surface of joints

Red bone marrow is located in the proximal _________

• Space in the middle of a long bone • In adults is filled with yellow marrow (fat)

Covers the epiphyses of long bones to form the surface of joints

Produces all types of blood cells

• Site of bone elongation • Consists of hyaline cartilage

• Remnant of epiphyseal plate after skeletal maturity • Dividing line between the epiphysis and diaphysis

As long as this is present you still have the potential to grow taller

Occurs roughly around the ages of 18-21

Osteogenic

• Double-layered membrane on the outside of living bone • Supplied with nerves + blood vessels and lymph vessels

Consists of a fibrous outer layer made up of dense irregular connective tissue, and an osteogenic inner layer made up mainly of osteoblasts
