1. How many muscles are in the body?
There is some variation, as with bones, but it is generally acknowledged that there are over 600.
2. Define muscle.
Muscle, more appropriately, myological tissue, is a dynamic network of multinucleic cells of actin, myosin, and troponin. Myological tissue is encased, grouped, and subdivided by fascia (epi, peri, and endo –mysium); fascia is a type of fibrose connective tissue. Additionally, skeletal and cardiac myological tissue have striations, which are composed of actin and troponin. The fascial sheath becomes a tendon at the origin and insertion loci.In the non-progressive myopathy, FSS, the fascial fibrose tissue ‘overtakes’ the ‘normal’ muscle, attenuating its movement.
3. Define tendon. [See #2]
4. Determine the difference between a sprain and a strain.
Sprains are a type of trauma resultant of non-anatomic stress on articulations and affect the structures in such locations, id est, ligaments, tendons, and bones. Strains are a type of trauma resultant of non-anatomic stress on myologic tissue and may present as a concomitant injury with sprains.
5. What does the acronym RICE stand for?
RICE is: rest, ice, compression, elevation.
6. How long should someone ice an injury?
Ice for 20 minutes and off. May do indefinitely, within first 24-72 hours after an injury.
7. What are the two joints that are most often sprained?
Tibiofemoral and talocrural joints are the most common sites of sprains. Great force in a non-anatomical way may occur, forcing these structures to hold a great amount of weight that is travelling at high speed. One of my profs (RLC) says, ‘Our body works well for “locomotion”, but it doesn’t work well for “motion” it wasn’t built for that.’
