When muscles of the body are exposed to electric shock‚ the muscles contract‚ the heart muscle goes into fibrillation electric shock can result in death AC is much more dangerous than DC An electrical shock is experienced when a person become part of an electric circuit. As a result‚ current enters at one point and leaves by another. The severity of the shock is determined by three main factors: The amount of current flowing through the body; The path of the current through the body. The great

The six fundamental movements of major body segments are: 1. Flexion: a decrease in the angle between two body segments. a. Example exercise – utilize the arm curl machine to perform preacher curls‚ flexion occurs at the elbow. 2. Extension: an increase in the angle between two body segments or the opposite of flexion. a. Example exercise – utilize the leg extension machine to perform quadriceps workout‚ extension occurs at knee. b. Hyperextension: extension of a limb or part beyond the normal

12/8/12 446-01 Mrs.Corrado Case Study – Packet 4 1. What is meant by a “complete‚ comminuted‚ intertrochanteric fracture of the right hip? a. A complete fracture is when the entire bone impacted is fractured. A comminuted fracture is when the bone breaks shatters into many pieces. Intertrochanteric refers to the top part of the femur. So‚ a complete‚ comminuted intertrochanteric fracture is the upper most part of the femur is completely shattered. A comminuted

in the body is extremely large. There are many different forms of fluid throughout the body‚ such as blood‚ urine‚ hormones‚ cerebral spinal fluid‚ water‚ albumin‚ and bile. The fluids that make up the body are required for homeostasis. There are many different functions of body fluids such as transporting nutrients‚ waste and gases‚ transforming food into energy and generate electrical activity to power body functions. Physiologic Fluid Compartments The major fluid compartments in the body are intracellular

(Hint: Getting Started) Specificity-what stretches and workouts need to be done to increase muscular fitness and flexibility. Progression-increase how long and how many times an exercise or workout is done. Overload- Stretching and workouts until body says no (muscular exhaustion) Reversibility- continuing to do stretches and workouts to not go back to where started Tedium-switching exercises and stretches daily to ensure everything is completed Frequently do stretches and workouts Intensity-
