3. (1) Coagulation and inflammation stage. (2) Migratory and proliferative stage. (3) Remodeling stage.

4. Neutrophils are white blood cells of the polymorphonuclear (PMN) leukocyte subgroup that appear during the inflammation stage. Neutrophils are filled with granules of toxic chemicals (phagocytes) that enable them to bind to microorganisms, internalize them, and kill them.

5. Monocytes are white blood cells of the mononuclear leukocyte subgroup. The monocytes migrate into tissues and develop into macrophages, and provide immunological defenses against many infectious organisms.

6. The lower crossed syndrome has the following characteristics: the erector spinae and iliopsoas are adaptively shortened (tight), the abdominals and gluteus maximus are weak, there is an anterior pelvic tilt, an increased lumbar lordosis, and a slight flexion of the hip.

8. Postural muscles—Relatively strong muscles that are likely to be poorly recruited, lax in appearance, show an inability to perform inner range contractions over time, or provide a stable base for other muscles to work from.

Phasic muscles—These muscles tend to become relatively weak compared to the postural muscles and are more prone to atrophy and adaptive shortening and show preferential recruitment in synergistic activities. In addition, these muscles will tend to dominate ...
