Block on a ramp and corresponding free body diagram of the block. In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the ...
Additionally, they can help to improve quality of life, [28] sleeping habits, [25] immune system function, [29] and body composition. [30] The study of the physiological responses to physical exercise and their therapeutic applications is known as exercise physiology, which is an important area of research within kinesiology.
The role of family caregivers is becoming increasingly important; care in the familiar surroundings of home may delay the onset of some symptoms and postpone or eliminate the need for more professional and costly levels of care. However, home-based care may entail tremendous economic and emotional costs.
Body cathexis is defined as the degree of satisfaction or dissatisfaction one feels towards various parts and aspects of their own body. [1] This evaluative dimension of body image is dependent on a person's investment of mental and emotional energy in body size, parts, shape, processes, and functions, and is integral to one's sense of self-concept.

The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organs and then organ systems. The external human body consists of a head, hair, neck, torso (which includes the thorax and abdomen), genitals, arms, hands, legs, and feet.
Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life-sustaining) functions. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery.
Swinging arms in an opposing direction with respect to the lower limb reduces the angular momentum of the body, balancing the rotational motion produced during walking. Although such pendulum-like motion of arms is not essential for walking, recent studies point that arm swing improves the stability and energy efficiency in human locomotion .
Mechanobiology is an emerging field of science at the interface of biology, engineering, chemistry and physics. It focuses on how physical forces and changes in the mechanical properties of cells and tissues contribute to development, cell differentiation, physiology, and disease.
