Bone Types

A force that, with enough energy, crushes tissue is a force

A condition that has a gradual onset with diffuse tenderness, inflammation and usually crepitus of a tendon is called:

A condition that is characterized by pain and discomfort during and immediately

after exercise?

The two types of muscle spasms are:

Calcium deposits in the muscle that result from repeated trauma is:

DOMS intensity peaks after 24-48 hours and then gradually decreases.

Ecchymosis is the bluish- purple discoloration of the skin usually after a

contusion.

Avulsion fractures are common when bone tissue is weaker than the tendon or ligament

attaching onto it.

A first-time dislocation should be treated as a possible fracture

Stress forces become concentrated where bones change shape and direction, leaving

them prone to fracture.

Humerus, ulna, tibia, radius

Skull, ribs, scapulae

Wrist and ankle

Vertebrae and jaw

Bonus

Most commonly injured type of

bone

2 force pairs act at opposite sidescausing a concave/ convex shape

Loads caused by twisting in oppositedirections

External loads applied towards oneanother from opposite directions

Equal but not directly opposite loads areapplied towards each other

Force that pulls or stretches tissue

All of the following are qualities of a synovial joint EXCEPT:

Does not moveLined with a synovial membrane Has a joint spaceHas a capsule or ligaments

All of the following are functions of bone EXCEPT:

Hematopoiesis (blood cells)Body supportOrgan protectionMineral production

A fracture that occurs on the side opposite to the point at which trauma was

initiated is a(n) fracture.

An incomplete break in the bone mostly seen in adolescents is a(n) ____________

fracture.

The greatest difficulty with grade 1 & 2 sprains is restoring stability due to

stretched tissue and inelastic scar tissue which forms

Dense white fibrous covering of a bone

Ends of the bone, provides area formuscle attachment

Hallow cylindrical part of a long bone, shaft

The property that allows tissue to return to normal after deformation is

When a load exceeds the ability of the tissue and tissue break down occurs it is

Make your wager

The point at which the tissue is deformed and will no longer have elasticity is
