Ground substance is an amorphous gel-like substance in the extracellular space of animals that contains all components of the extracellular matrix (ECM) except for fibrous materials such as collagen and elastin. [1] Ground substance is active in the development, movement, and proliferation of tissues, as well as their metabolism.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Between the molecules that make up the ground substance there are minimal surfaces of potential energy. The charging and discharging of the materials of the ground substance cause 'biofield oscillations' (photon fields). The interference of these fields creates short lived (from 10–9 to up to 10–5 seconds) tunnels through the ground substance.
Connective tissue is found in between other tissues everywhere in the body, including the nervous system. The three meninges, membranes that envelop the brain and spinal cord, are composed of connective tissue. Most types of connective tissue consists of three main components: elastic and collagen fibers, ground substance, and cells. [2]
In vivo, hyaluronic acid forms randomly kinked coils that entangle to form a hyaluronan network, slowing diffusion and forming a diffusion barrier that regulates transport of substances between cells. For example, hyaluronan helps partition plasma proteins between vascular and extravascular spaces, which affects solubility of macromolecules in ...
Total body water in healthy adults is about 50–60% (range 45 to 75%) of total body weight; [1] women and the obese typically have a lower percentage than lean men. [2] Extracellular fluid makes up about one-third of body fluid, the remaining two-thirds is intracellular fluid within cells. [3]
Osteoid makes up about fifty percent of bone volume and forty percent of bone weight. It is composed of fibers and ground substance. The predominant type of fiber is type I collagen and comprises ninety percent of the osteoid. The ground substance is mostly made up of chondroitin sulfate and osteocalcin.
a ground substance made of other organic compounds; The collagen and hydroxyapatite are held together by a strong protein-mineral bond that provides bone with its strength and its ability to remain long after the soft tissue of a body has been degraded. [4] The process that degrades bone is referred to as diagenesis.
