Structure-How We’re Put Together


Axial (skull, spine, ribs,
sternum, breastbone)
Appendicular (shoulders,
arms, legs, hands, hips,
feet)
What’s Inside Our Bones?




Spongy Bone
Marrow Cavity
Compact Bone
Cartilage
Different Types of Bones




Long
Short
Flat
Irregular
Cartilage



A type of connective tissue
Lines joints to cushion the bone and allow the
joint to move easily without pain
Helps form flexible portions of the nose and
ear


What kind of joint is
your knee?

Ligaments and Tendons


Ligaments connect bone to bone
Tendons connect muscle to bone
Eating Your Way to Strong Bones

Diet


Milk is rich in calcium and
high-quality protein.
Nearly all U.S. milk has
vitamins D and A added
and it has magnesium
and zinc.

Problems of the Skeletal System

Fractures



Hairline
Transverse
Comminuted
Osteoporosis

What?


A disease causing the
bones to become very
porous
This makes bones prone
to fractures and slow to
heal

Who?


Most common in women
following menopause
More common in females
Osteoporosis
Scoliosis

What?


An abnormal lateral
curvature of the spine
Who?


Scoliosis can affect
anyone
Why?



Birth defect
Nerve or muscle
problems
deterioration of the bony
material (discs) that
separate the vertebrae
Joint Injuries





Dislocation
Torn cartilage
Bunion
Bursitis
Arthritis
Repetitive Motion Injury

What?

