  other minerals.

6
Bones

• Bone shapes include ________ bones, _________
  bones, flat bones, and ______________ bones.

Flat bone(rib)
Long bone(humerus)
Short bone(wrist)

Connective Tissue
Three Types of Connective Tissue
__________
__________
__________
8
Connective Tissue

• __________ can act as a cushion between
  _____________ or as a flexible structure for soft
  parts of the body, such as the tip of the nose.

Cartilage
A strong, flexible connective tissue
9
Connective Tissue

• All bones begin in the embryo as cartilage. Early
  in development, the cartilage hardens in a
  process called _______________________.

__________________
The process by which bone is formed, renewed, and
repaired
10
Connective Tissue

• _______________ attach to bones to create joints.

__________________
A band of fibrous, slightly elastic connective
tissue that attaches one bone to another
11
Connective Tissue

• Muscles and tendons work together to move parts
  of the body.

Tendon
A fibrous cord that attaches muscle to the bone
12
Connective Tissue

• Joints are points at which bones meet. Some
  joints are flexible and some do not move.
• The structure of a joint relates to the type of
  motion it can produce.

skin.
________________________________
________________________________
The broken bone does not break through the skin.
19
Fractures
Fractures are also classified by the pattern of
the break.
Hairline Fractures
Parts of the bone do not separate.
Transverse Fractures
The fracture is completely across the bone.
Comminuted Fractures

Injuries to Joints
Occurs when a bone slips out of place, tearing
the ligaments that attach the bone at the joint.
________________
Can result from a sharp blow to a joint or a
severe twisting of a joint.
Torn Cartilage
Painful inflammation of bursa, a fluid-filled sac
that helps reduce friction in joints.
Bursitis
Painful swellings of the bursae in the first
joints of big toes.
Bunions
Inflammation of a joint, resulting from an
injury, natural wear and tear, or autoimmune
disease.
