To understand how the human body works, we need to know that gravity has an effect on all living things on the Earth. It has taken hundreds of years of research to figure out how gravity affects these biological systems.
Both direct and indirect effects have been looked at by the people who did this. It all began with the development of mechanics, which was concerned with how physical bodies behave when they are subjected to forces or displacements, as well as how that behavior affects their surroundings. It then went on to the development of physics and mathematics.
To figure out how these mechanical interactions worked, and that led to the creation of a new field of study called biomechanics.
In biomechanics, we look at how biological systems move, how they move, how they move and how they move. We also look at how mechanical forces affect things like movement, size, shape, and structure. Mechanical forces can have an impact on biological systems at many different levels, from the molecular and cellular to the tissue, organ, and system levels. So, biomechanics is about everything from how cells work to how soft and hard tissues move and how the neuromusculoskeletal system grows and moves, too. How mechanical forces and deformation affect the shape, binding or reaction, function, and transport of biomolecules like DNA, RNA and proteins is called molecular biomechanics. It also looks at how mechanobiochemistry is linked to biomolecular motors and ion channel flows, and how these two things work together. Cellular biomechanics is the study of how cells sense and respond to mechanical forces or deformations. It focuses on how these forces affect cell growth, differentiation, movement, signal transduction, protein secretion and transport, and gene expression and regulation, among other things. Loads and deformations can change the characteristics of living tissues. Tissue biomechanics is mostly about how tissues grow and change in response to mechanical stimuli.
In human biomechanics, forces applied to the musculoskeletal system and the response of body tissue to these forces are studied. Depending on the forces involved in movement and posture, biomechanics can be seen from the perspective of exterior or internal biomechanics.
Body tissue reacts to external forces acting on the segment by creating forces that interact in order to accomplish the desired movement and posture.
The internal resistance of a material, often known as “stress,” increases when it is subjected to an external force or load. The total resistance created is divided by the external load.
The structure’s shape is somewhat altered or deformed as a result of the stress. A wavy pattern visible under a microscope in dense connective tissue is the crimp, or crimp characteristics of connective tissue.
elasticity’s characteristics
A high concentration of collagen fibers and a low number of cells and ground substance are characteristics of dense connective tissue. Dense connective tissue has viscoelastic qualities, for instance. When the stress is removed, an exceptionally dense connective tissue fibre can grow briefly before returning to its original size.
Compliance is what happens when dense connective tissue contracts.
The ability of a tissue to return to its normal length once a stress has been removed is referred to as elasticity.
When dense connective tissues are extended to their physiological limit, a connected collagen fiber’s crimp feature is lost. The stress-strain curve can help us determine a dense connective tissue’s physiologic limit, which is vital to remember while stretching it.
