Musculoskeletal System Review
1. List the four types of bones.
Long bone – has a long, thin shape. ...
Short bone – has a squat, cubed shape. ...
Flat bone – has a flattened, broad surface. ...
Irregular bone – has a shape that does not conform to the above
three types.
2. List the six functions of the skeletal system.
The human skeleton serves six major functions: support, movement,
protection, production of blood cells, storage of ions, and endocrine
3. List six things that affect bone growth.
Calcium Levels
Physical activity
Tobacco and alcohol use
Race and family history
Hormone levels
4. What is the role of Vitamin D and Calcium in bone growth?
Calcium and vitamin D work together to protect your bones—calcium
helps build and maintain bones, while vitamin D helps your body
effectively absorb calcium.
5. Define “osteoblasts” and “osteoclasts”.
Osteoblasts are specialized mesenchymal cells that synthesize bone
matrix and coordinate the mineralization of the skeleton.
Osteoclast, large multinucleated cell responsible for the dissolution
and absorption of bone. ... Osteoclasts are formed by the fusion of
many cells derived from circulating monocytes in the blood.
6. List the three types of joints.
synarthroses (immovable)
amphiarthroses (slightly movable)
diarthroses (freely movable)
7. List the three types of muscle tissue.
Skeletal muscle – the specialised tissue that is attached to bones
and allows movement. ...
Smooth muscle – located in various internal structures including
the digestive tract, uterus and blood vessels such as arteries. ...
Cardiac muscle – the muscle specific to the heart.
8. What is the primary function of skeletal muscle?
Skeletal muscles enable humans to move and perform daily activities.
They play an essential role in respiratory mechanics and help in
maintaining posture and balance. They also protect the vital organs in
the body.
9. Define tendon and ligament.
Tendons - are the connective tissues that transmit the mechanical
force of muscle contraction to the bones; the tendon is firmly
connected to muscle fibres at one end and to components of the bone
at its other end
Ligaments - a short band of tough, flexible fibrous connective tissue
which connects two bones or cartilages or holds together a joint.
10. What is a goniometer?
an instrument for the precise measurement of angles, especially one
used to measure the angles between the faces of crystals.
11. Define lordosis, kyphosis, and scoliosis.
Lordosis is an exaggerated inward curve of the spine that typically
affects the lower back, a condition called lumbar lordosis.
12. What is a bone scan used for? What diseases can it detect?
A bone scan is a specialized radiology procedure used to examine the
various bones of the skeleton. It is done to identify areas of physical
and chemical changes in bone. A bone scan may also be used to
follow the progress of treatment of certain conditions. Pagets disease
13. Define Osteoporosis.
A condition in which bones become weak and brittle.
14. What are some risk factors for osteoporosis?

Asian descent.
Family history. ...
Body frame size.
15. How can one prevent osteoporosis?
1. have a healthy and varied diet with plenty of fresh fruit,
vegetables and whole grains.

4. avoid smoking.
5. limit alcohol consumption.
6. limit caffeine.
7. do regular weight-bearing and strength-training activities
16. Define osteomalacia.
Osteomalacia refers to a marked softening of your bones, most often
caused by severe vitamin D deficiency. The softened bones of
children and young adults with osteomalacia can lead to bowing
during growth, especially in weight-bearing bones of the legs.
Osteomalacia in older adults can lead to fractures
17. Define Pagets Disease.
Paget's (PAJ-its) disease of bone interferes with your body's normal
recycling process, in which new bone tissue gradually replaces old
bone tissue. Over time, bones can become fragile and misshapen.
The pelvis, skull, spine and legs are most commonly affected.
18. Define osteomyelits.
Osteomyelitis is inflammation or swelling that occurs in the bone. It
can result from an infection somewhere else in the body that has
spread to the bone, or it can start in the bone — often as a result of an
injury. Osteomyelitis is more common in younger children (five and
under) but can happen at any age
19. Define osteochondroma.
Osteochondroma is an overgrowth of cartilage and bone that happens
at the end of the bone near the growth plate. Most often, it affects the
long bones in the leg, the pelvis, or the shoulder blade.
Osteochondroma is the most common noncancerous bone growth. It
most often occurs between ages 10 and 30.
20. Define osteosarcoma.
Osteochondroma is an overgrowth of cartilage and bone that happens
at the end of the bone near the growth plate. Most often, it affects the
long bones in the leg, the pelvis, or the shoulder blade.
Osteochondroma is the most common noncancerous bone growth. It
most often occurs between ages 10 and 30.
21. Define Carpal Tunnel Syndrome and its management.
Carpal tunnel syndrome, also called median nerve compression, is
a condition that causes numbness, tingling, or weakness in your hand.
It happens because of pressure on your median nerve, which runs the
length of your arm, goes through a passage in your wrist called the
carpal tunnel, and ends in your hand.
22. What is Phalen’s maneuver?
What is the Phalen's Maneuver? The clinical term “Phalen's
Maneuver” refers to a provocative test used in the diagnosis of carpal
tunnel syndrome. We also know this as a wrist-flexion test 1. Carpal
tunnel syndrome (CTS) refers to a condition that puts pressure on a
nerve in your wrist
23. Define Hallux Valgus.
Hallux valgus is the most common foot deformity. It is a progressive
foot deformity in which the first metatarsophalangeal (MTP) joint is
affected and is often accompanied by significant functional disability
and foot pain and reduced quality of life.
24. Define osteogenesis imperfecta.
Osteogenesis imperfecta (OI) is an inherited (genetic) bone disorder
that is present at birth. It is also known as brittle bone disease. A child
born with OI may have soft bones that break (fracture) easily, bones
that are not formed normally, and other problems. Signs and
symptoms may range from mild to severe.
25. Define Muscular Dystrophy and treatments for this disease.
Muscular dystrophy is a group of diseases that cause progressive
weakness and loss of muscle mass. In muscular dystrophy, abnormal
genes (mutations) interfere with the production of proteins needed to
form healthy muscle. There are many kinds of muscular dystrophy.
Treatment consists of steroids
Medications, therapy, breathing aids, or surgery may help maintain
function, but life span is often shortened.
26. List the two types of fractures.
Open and Closed fractures
27. Define open and closed fractures.
Open fracture (compound fracture): The bone pokes through the skin
and can be seen. Or a deep wound exposes the bone through the
skin. Closed fracture (simple fracture). The bone is broken, but the
skin is intact.
A closed fracture is a broken bone that does not penetrate the skin.
This is an important distinction because when a broken bone
penetrates the skin (an open fracture) there is a need for urgent
treatment, and an operation is often required to clean the area of the
28. List the eight most common types of fractures.
Stable Fracture
Transverse Fracture
Comminuted Fracture
Oblique Fracture
Compound Fracture
Hairline Fracture
Avulsion Fracture
Greenstick Fracture

Blood vessel damage
Pulmonary embolism
Fat embolism
Compartment syndrome
Joint problems
Uneven limbs
30. What is the treatment for a fat embolism?
There is no specific treatment for a fat embolism. That is why
prevention can reduce the length of hospital stays and lower the risk
of complications and death. Some preventative strategies include :
blood oxygen monitoring to help detect a fat embolism early, before
symptoms become severe.
31. List the assessments of adequate blood flow to an injured
The five main assessments that must be completed when assessing
distal circulation are capillary refill, color, temperature, pulses and
32. List the emergency care for a fracture.
1. Stop any bleeding. Apply pressure to the wound with a sterile
bandage, a clean cloth or a clean piece of clothing.
2. Immobilize the injured area. Don't try to realign the bone or push
a bone that's sticking out back in. ...
3. Apply ice packs to limit swelling and help relieve pain. ...
4. Treat for shock.
33. List non-surgical management of fractures.
Non-operative (closed) therapy comprises of casting and traction (skin
and skeletal traction). Closed reduction is done for any fracture that is
displaced, shortened, or angulated. Splints and casts made up of
fiberglass or plaster of Paris material are used to immobilize the limb.
34. List the surgical management of fractures.
Open reduction, and internal fixation- this involves a surgery to
repair the fracture-frequently, metal rods, screws or plates are
used to repair the bone, and remain in place, under the skin,
after the surgery.
35. Define amputation.
An amputation is the surgical removal of part of the body, such as an
arm or leg. This topic may be helpful if you, a friend, or a member of
your family, recently had or are planning to have an amputation.

heart problems such as heart attack.
deep vein thrombosis (DVT)
slow wound healing and wound infection.
stump and "phantom limb" pain.

down over the crutches. There should be a two inch space between
your armpit and the top of the crutch with your hands hanging relaxed.
The hand grips should be at the level of your wrist when holding the
hand grips

Red meat, lamb, and pork.
Organ meats, such as liver, kidneys, and glandular meats like
the thymus or pancreas (you may hear them called sweetbreads)
Seafood, especially shellfish like shrimp, lobster, mussels,
anchovies, and sardines.
40. Differentiate between RA and OA.
The main difference between osteoarthritis and rheumatoid arthritis
is the cause behind the joint symptoms. Osteoarthritis is caused by
mechanical wear and tear on joints. Rheumatoid arthritis is an
autoimmune disease in which the body's own immune system attacks
the body's joints. It may begin any time in life
