'No system of your body works independently, gets injured without affecting another or has the ability to heal by itself'
Fascial System
Is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches to, stabilizes, encloses, and separates muscles and other internal organs. Fascia is classified by layer, as superficial or deep fascia and visceral or parietal fascia, or by its function and anatomical location.
Like ligaments, aponeuroses, and tendons, fascia is made up of fibrous connective tissues containing closely packed bundles of collagen fibres oriented in a wavy pattern parallel to the direction of pull. Fascia is consequently flexible and able to resist great unidirectional tension forces until the wavy pattern of fibres has been straightened out by the pulling force. These collagen fibres are produced by fibroblasts located within the fascia.
Fasciae are similar to ligaments and tendons as they have collagen as their major component. They differ in their location and function: ligaments join one bone to another bone, tendons join muscle to bone, and fasciae surround muscles and other structures
Muscular System
This system includes the skeletal muscles that move the skeleton, the face, and other structures giving form to the body. The cardiac muscle pumps blood through the heart: smooth muscle moves the contents of the viscera, vessels and glands and also moves the hair and skin.
Nervous System
This system consists of impulse - generating / conducting tissue organised into a central nervous system (brain and spinal cord) and a peripheral nervous system (nerves). The peripheral nervous system includes the visceral (autonomic) nervous system, which is involved in involuntary 'fight or flight' and vegetative functions.
Consists of the four chambered heart; arteries conducting blood to the tissues; capillaries through which nutrients, gases and molecular material pass to and from the tissues; and veins returning blood from the tissues to the heart
Lymphatic System
Is a system of vessels assisting the veins in recovering the body's tissue fluids and returning them to the heart. The lymph nodes filter lymph throughout the body
Digestive Systems
Covers the alimentary canal and gland. It performs the breakdown, digestion, and assimilation of food as well as excretion of the residua. Glands include the liver, pancreas and the biliary system (gallbladder and related ducts)
Endocrine System
A series of glands that secrete chemical agents (hormones) into the tissue fluids and blood, affecting the function of multiple areas of the body - very much including the brain. Hormones help maintain balanced metabolic functions in many parts of the body.
Integumentary System
Consists of the skin, which is provided with many glands, sensory receptors, vessels, immune cells, antibodies and layers of cells and keratin that resist environmental factors harmful to the body.
Reproductive System
Male = secretes male sex hormones, forms and maintains germ cells (sperm) and transports germ cells to the female genital tract
Female = secretes sex hormones, produces and transports germ cells (ova), receives and transports male germ cells to the fertilisation site, maintains the developing embryo / fetus, and sustains the fetus till birth,.
Respiratory System
Consists of the upper (nose through larynx) and lower respiratory tract (trachea through the air spaces of the lungs). Most of the tract is airway; only the air spaces (alveoli) and very small bronchioles exchange gases between alveoli and the lung capillaries.
Skeletal System
Covers the bones and the ligaments that secure the bones at the joints.
There are 206 bones in the human body.
Endocannabinoid System
A chemical communication system with the goal of maintaining homeostasis. Homeostasis keeps the internal environment stable, regardless of how the external environment fluctuates.
Limbic System
A term for the set of brain structures including the hippocampus, amygdala, anterior thalamic nuclei and a limbic cortex that support a variety of functions including emotion, behaviour and long term memory
