Acids Bases and pH Scale. I. Acids *Acids are ionic compounds (a compound with a positive or negative charge) that break apart in water to form a hydrogen ion (H +). *The strength of an acid is based on the concentration of H + ions in the solution.The more H+ the stronger the acid.*The pH scale is a measure of the hydrogen ion concentration. It spans from 0 to 14 with the middle point (pH 7) being neutral (neither acidic or basic). Any pH number greater than 7 is considered a base and any pH number less than 7 is considered an acid. 0 is the strongest acid and 14 is the strongest base.
The pelvic muscles are positioned like a mini trampoline that slings across the area where you sit. They run from the pubic bone at the front, to the lower part of the tail bone at the back and from side to side between the sit bones. The pelvic floor muscles are positioned in layers in the floor of the pelvis. This position can make them vulnerable to strain and injury, especially in women.
The pedicle is a short, stem-like projection located on the backside of a vertebral body. A pedicle lies on either side of the vertebral body and connects to the facet joint, bridging the front and back sections of the vertebra. The rounded hollows above and below the pedicle are known as vertebral notches.
