The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord. The central nervous system is so named because it integrates information it receives from, and coordinates and influences the activity of all parts of the body. Arguably, many consider the retina and the optic nerve as well as the olfactory nerves and olfactory epithelium as parts of the CNS, synapsing directly on brain tissue without intermediate ganglia. This classification is the only central nervous tissue in direct contact with the environment, which opens up for therapeutic treatments. The CNS is contained within the dorsal body cavity, with the brain housed in the cranial cavity and the spinal cord in the spinal canal. In vertebrates, the brain is protected by the skull, while the spinal cord is protected by the vertebrae. A hollow organ is a visceral organ that forms a hollow tube or pouch, such as the stomach or intestine, or that includes a cavity, like the heart or urinary bladder. For instance, the nervous and endocrine system both operate via a shared organ, the hypothalamus. For this reason, the two systems are combined and studied as the neuroendocrine system.
The same is
true for the musculoskeletal system because of the relationship between the
muscular and skeletal systems. Cardiovascular system: pumping and channeling
blood to and from the body and lungs with heart, blood and blood vessels.
Digestive system: digestion and processing food with salivary glands,
esophagus, stomach, liver, gallbladder, pancreas, intestines, colon, rectum and
anus. Endocrine system: communication within the body using hormones made by
endocrine glands such as the hypothalamus, pituitary gland, pineal body or
pineal gland, thyroid, parathyroid and adrenals, i.e., adrenal glands.
Excretory system: kidneys, ureters, bladder and urethra involved in fluid
balance, electrolyte balance and excretion of urine.
Immune System:
structures involved in the transfer of lymph between tissues and the blood
stream, the lymph and the nodes and vessels that transport it including the
Immune system: defending against disease-causing agents with leukocytes,
tonsils, adenoids, thymus and spleen. Integumentary system: skin, hair and
nails. Muscular system: movement with muscles. Nervous system: collecting,
transferring and processing information with brain, spinal cord and nerves.
Reproductive system: the sex organs, such as ovaries, fallopian tubes, uterus,
vagina, mammary glands, testes, vas deferens, seminal vesicles, prostate and
penis. Respiratory system: the organs used for breathing, the pharynx, larynx,
trachea, bronchi, lungs and diaphragm. Skeletal system: structural support and
protection with bones, cartilage, ligaments and tendons.
The Vital
Organs can be temporarily or permanently damaged by impact from being struck by
hands elbows and knees and feet. The
Brain can cause a person to be Dazed and Blackout/Pass out from Punch of the
hand connecting on the temple or from under the chin. The eyes can disable a
person’s vision of a poke to the eye from the finger. A “Ringing” in the ear
sound is heard from a hands being quickly slammed on to both ears in a clapping
motion. The throat can be closed from a choke of the hand or forearms which
creates a tightening of the air way and oxygen becomes less to their lungs. The
sternum/breastbone can cause sealing of breath in the lungs once impacted from
a punch of the hand, being struck by a knee or taking a kick from the foot. As
well as the abdomen. The liver can cause a person to lose Focus or even
consciousness by the same hit of the punch, knee or foot. Lose of bladder control
from impact is possible.
