8/31 Injury Response Process Pt 1

A theory stating that the body has a common mechanism for adapting to stress.

general adaptation syndrome

What are the three stages of general adaptation syndrome?

alarm, resistance, and exhaustion

What condition is necessary for the body to develop physiological resistance to stress?

stress is applied with proper intensity and duration

What are the five soft tissue types?

epithelial, adipose, muscular, nervous, and connective

What are the primary functions of epithelial tissue?

secretion and absorption of substances

Does epithelial tissue contain blood vessels?

no, it is avascular

What is the regenerative capacity of epithelial tissue?

excellent potential

What is the stratum corneum?

the skin’s outermost layer composed of densely packed dead cells

What protein fills cells in the stratum coreum?

keratin

What are the two major junctions of the straum corneum?

prevent germs from entering the body and help retain body fluids

How does ultrasound interact with the stratum corneum?

it passes through relatively easily

Why does the stratum corneum resist electrical current?

dead, dry cells are poor conductors

Through what structures do medications pass during iontophoresis or phonophoresis?

hair follicles and sweat glands

What is the primary storage function of adipose tissue?

fat

Why is adipose tissue a good medium for ultrasound?

because it has a high water content

How does adipose tissue affect heat and cold treaments?

thick adipose tissue reduces the effectiveness of heat and cold packs

What thermal role does adipose tissue serve?

provides insulation against cold

What characterizes Type I (slow-twitch) fibers?

Slow to fatigue and common in postural muscles

What characterizes Type II (fast-twitch) fibers?

Produce high force in a short period of time.
