- Long Bones
- Broader than long
- Cube-like shape
- Provide stability, support,
while allowing for some motion.
- Short Bones
- Thin flattened shape
- Points of attachment for muscles
- Protector of internal organs
- Flat Bones
- Complex shape
- Protect internal organs, movement
Irregular Bones

- allow effective muscle action
Sesamoid
central shaft
Diaphysis
two ends
Epiphysis
covers the ends of
epiphysis
- Articular cartilage
site of
growth in bone length
Epiphyseal plate
called when growth in bone
length of epiphyseal plate stops
Epiphyseal line
soft tissue in the medullary cavities of the bone
Marrow
made mostly of fat and contains stem cells that can become cartilage, fat or bone cells.
Yellow marrow
consists of blood forming cells and is the
only site of blood formation in adults
Red marrow
Mostly solid matrix and cells
- Forms the hard, dense
outer layer of bones
throughout the human body
- Provide strength and
protection to bones
Compact Bone
Consist of a lacy network of
bone with many small,
marrow- filled spaces.
- Provide greater strength
and rigidity
Cancellous bone
this protecting the
delicate organs in the body
Axial Skeleton

the upper and lower extremities,
which include the shoulder girdle
and pelvis.
Appendicular skeleton

the body

Pubis

Ischium

Acetabulum
formed when two bones meet to allow
movement.
Joints
a synovial joint built
between two bones that meet on flat
articular surface allowing sliding or gliding
motion
Gliding joint
type of joint that function
much like the hinge on a door,
allowing bones to move in one
direction back and forth with
limited motion along other
planes.
Hinge Joint
Enable bones to move
freely in all directions
Ball and socket joint
- the joint allows back
and forth motion as well
ups and down
movement.
Saddle Joint
are bands of tough elastic
tissue around joints.
Ligaments
connect muscle to bones.
A cord strong and flexible
tissue similar to rope.
Tendons
A strong, flexible
connective tissue that
protect joints and bones.
