A researcher is conducting an experiment testing whether a new pharmaceutical drug is able to effectively treat heartburn and has a physician assisting with the study involving volunteers who experience chronic heartburn. Which of the following descriptions most closely describes the control used in this study? Show answer choices The researcher has organized the patients into 4 groups, where patients either take 1 dose of the drug, 2 doses of the drug, 1 dose of the placebo, or 2 doses of the placebo. The physician asks patients to rate their heartburn discomfort on a scale from 1-10 every 5 minutes up to an hour. The physician and patients both do not know if they are receiving the actual drug or a placebo. The placebo pill contains just compressed sugar and no active drug. Patients are randomly selected and placed into the four categories.
Musculoskeletal System
The musculoskeletal system, also called the locomotor system, is an organ system that gives humans and animals the ability to move using their muscular and skeletal systems. It provides stability, form, support, and movement to the body. The skeleton is composed of bones (skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system is subdivided into two broad systems, such as the muscular system and the skeletal system.
Skeletal structure
The skeletal system is the core framework of the human body. The skeletal structure comprises bones and connective tissue, including cartilage, ligaments, and tendons. The skeletal structure of our body acts as a support structure. It maintains the body's shape and is responsible for its movement, blood cell formation, protection of organs, and mineral storage. The skeletal system is referred to as the musculoskeletal system.
