What are the three types of forces acting on connective tissue?

Compression, tension, and sheer.

What does compression force do to tissue?

It crushes or pushes tissue together.

How does tension force affect connective tissue?

It pulls the tissue apart or stretches it.

What is sheer force in the context of connective tissue?

A force movement against the parallel structures of connective tissue.

How do connective tissues respond to tension forces compared to sheer or compression forces?

Connective tissues are reasonably good at withstanding tension forces but not good at withstanding sheer or compression.

What injury is associated with compression force?

Contusion.

What injuries can result from sheer or excessive tension forces?

Capsular or ligament sprain.

What are some signs and symptoms of a fracture?

Pain at the site, deformity, immobility, edema (swelling), ecchymosis (bruising), grating or crepitus, numbness or tingling, and pale or cold skin due to impaired circulation.

What is myositis ossificans?

A condition in which calcium is produced within the muscle after a blow, potentially creating a hard immovable mass within the muscle.

What causes tendonitis?

Repeated stress to the tendon causes microtears of the tendon sheath, resulting in inflammation.
