SKELETAL SYSTEM
Skeleton

Axial skeleton

- Forms the long axis of the body (vertical)
- Includes bones of the skull, vertebral column and rib cage
- Protect, support and carry other body parts

Appendicular skeleton

- Bones of upper and lower limbs and the girdles (shoulder, hip, leggs, arms and hands)




Structure of Bone

Compact/ cortical bone

- Surrouned by periosteum
- Contains pipe-like structures called osteons, they contain hollow centers for nerves
and blood cells

Spongy/ trabecular bone

- Looser structure: branching rods called trabeculae
- Contains bone marrow
- Consists of hematopoietic stem cells (“red marrow”) and adipocytes/ fat cells
(“yellow marrow”, usually in center)
o Red marrow ensures production of blood cells
o Yellow marrow ensures production of fat

,  yellow can turn into red when a person gets anemia and needs more red
blood cells




Long bones

- Epiphysis
Outer ends of the bone, often wider as diaphysis. Outside contains compact bone
and inside spongy bone, the top is covered with cartilage.

- Ephipysial line
Remnant of ephysial plate, called also metaphysis.

- Diaphysis
Long axis of the bone, consist of compact bone containing marrow cavity

- Membranes (periosteum, endosteum)
o Periosteum= double- layer membrane which
surrounds the outer bone. It contains nerve
fibers and blood vessels, receive nutrients to
marrow. And provides anchoring points for
tendons.
 Outer layer consist of irregular connetive
tissue.
 Inner layer consist mainly of primitive
stem cells, from which all bone cells arise

o Endosteum = covers the internal surfaces of the
bone, contains cells that can differentiate in
other bone cells
