2. Skeletal System
Bone types
Bone structure
Bone function
Bone growth and metabolism affected
by calcium and phosphorous,
calcitonin, vitamin D, parathyroid,
growth hormone, glucocorticoids,
estrogens and androgens, thyroxine,
and insulin.
3. Bones
Human skeleton has 206 bones
Provide structure and support for soft
tissue
Protect vital organs
6. Bones
Compact bone
◦ Smooth and dense
◦ Forms shaft of long bones and outside
layer of other bones
Spongy bone
◦ Contains spaces
◦ Spongy sections contain bone marrow
7. Bone Marrow
Red bone marrow
◦ Found in flat bones of sternum, ribs, and
ileum
◦ Produces blood cells and hemoglobin
Yellow bone marrow
◦ Found in shaft of long bones
◦ Contains fat and connective tissue
10. Synovial Joints
Found at all limb articulations
Surface covered with cartilage
Joint cavity covered with tough fibrous
capsule
Cavity lined with synovial membrane
and filled with synovial fluid
11. Ligaments
Bands of connective tissue that
connect bone to bone
Either limit or enhance movement
Provide joint stability
Enhance joint strength
12. Tendons
Fibrous connective tissue bands that
connect bone to muscles
Enable bones to move when muscles
contract
13. Muscles
Skeletal (voluntary)
◦ Allows voluntary movement
Smooth (involuntary)
◦ Muscle movement controlled by internal
mechanism
◦ e.g., muscles in bladder wall and GI
system
Cardiac (involuntary)
◦ Found in heart
14. Skeletal Muscle

Made up of thick bundles of parallel
fibers
Each muscle fiber made up of smaller
structure myofibrils
Myofibrils are strands of repeating
units called sarcomeres
15. Skeletal Muscle
Skeletal muscle contracts with the
release of acetylcholine
The more fibers that contract, the
stronger the muscle contraction
16. Changes in Older Adult
Musculoskeletal changes can be due
to:
◦ Aging process
◦ Decreased activity
◦ Lifestyle factors
17. Changes in Older Adult
Loss of bone mass in older women
Joint and disk cartilage dehydrates
causing loss of flexibility contributes to
degenerative joint disease
(osteoarthritis); joints stiffen, lose
range of motion
18. Changes in Older Adult
Cause stooped posture, changing
center of gravity
Elderly at greater risk for falls
Endocrine changes cause skeletal
muscle atrophy

108. Phantom Limb Pain
Phantom limb pain is a frequent
complication of amputation.
Client complains of pain at the site
of the removed body part, most
often shortly after surgery.
Pain is intense burning feeling,
crushing sensation or cramping.
Some clients feel that the removed
body part is in a distorted position.
109. Management of Phantom Pain
Phantom limb pain must be
distinguished from stump pain
because they are managed
differently.
Recognize that this pain is real and
interferes with the amputee’s
activities of daily living.
(Continued)
110. Management of Phantom Pain
(Continued)
Some studies have shown that
opioids are not as effective for
phantom limb pain as they are for
residual limb pain.

osteoporosis
Major treatment: vitamin D from
exposure to sun and certain foods
129. Paget’s Disease of the Bone
Metabolic disorder of bone remodeling,
or turnover; increased resorption (the
process by which osteoclasts break down bone and
release the minerals, resulting in a transfer of calcium
from bone fluid to the blood) of loss results in
bone deposits that are weak, enlarged,
and disorganized
Nonsurgical management: calcitonin,
selected bisphosphonates, mithramycin
