| THE NERVOUS SYSTEM AND FUNCTIONS
There are many things that can impair nerve function and as a result decrease your over all health. The spinal chord and spinal nerves connect your brain to the rest of your body. There are 12 Cranial Nerves and 31 Spinal Nerves (Some text say 26, counting the sacral as one solid piece)spinal cord nerve segments in a human spinal cord:
NERVES OF THE BODY
CRANIAL - 12 cranial nerves. (They exit from the base of the brain and brainstem)
CERVICAL - 8 cervical segments forming 8 pairs of cervical nerves (C1 spinal nerves exit spinal column between occiput and C1 vertebra; C2 nerves exit between posterior arch of C1 vertebra and lamina of C2 vertebra; C3-C8 spinal nerves through IVF above corresponding cervica vertebra, with the exception of C8 pair which exit via IVF between C7 and T1 vertebra)
THORACIC - 12 thoracic segments forming 12 pairs of thoracic nerves (exit spinal column through IVF below corresponding vertebra T1-T12)
LUMBAR - 5 lumbar segments forming 5 pairs of lumbar nerves (exit spinal column through IVF, below corresponding vertebra L1-L5)
SACRAL - 5 (or 1) sacral segments forming 5 pairs of sacral nerves (exit spinal column through IVF, below corresponding vertebra S1-S5)
COCCYX - 1 coccygeal segment forming 1 pair of coccygeal nerves (exit spinal column through the sacral hiatus)
COMMUNICATION GONE BAD
There is constant communication between the brain and the body and the body back up to your brain. Most nerve related issues come from an injury during the course of someone's life. The condition that forms from an injury is called an Subluxation (Pressure on the nervous system from the bones and soft tissue at the injured area). The problem comes in when the signals are blocked, which then causes the body to function poorly and create health issues. Below you will see how vast the nervous system is and how much the nervous system controls and regulates on a daily basis.
WHAT EACH SECTION CONTROLS
CRANIAL NERVES
- control and regulate: blood to the head, smell, visual acuity, scalp, brain, eyelids, eye movements, pupillary constriction, sensation to cornea, forehead, nose, mouth teeth, tongue, sensation of ear, facial skin, taste sensations, secretion of saliva and tears, hearing, swallowing, speaking, gag reflex, blood flow, secretion of digestive enzymes, moving food through the digestive system, involuntary action of heart, lungs and digestive tract, turning the head and shrugging shoulders.
CERVICAL SPINAL NERVES
- control and regulate: the top of the head, base of the skull, neck muscles, shoulders, elbows, arms, wrists, hands, fingers esophagus, heart, coronary arteries, lungs, chest, breast, diaphragm.
THORACIC SPINAL NERVES
- control and regulate: blood to the head, brain, eyes, ears, nose, sinuses, mouth, esophagus, heart, lungs, breast, gallbladder, liver, diaphragm, stomach, pancreas, spleen, kidneys, small intestines, uterus, apendix, buttocks, colon.
LUMBAR SPINAL NERVES
- control and regulate: uterus, large intestines, buttocks, groin, reproductive organs, colon, upper legs, knees, sciatic nerve.
SACRAL SPINAL NERVES
- control and regulate: buttocks, reproductive organs, bladder, prostate gland, sciatic nerve, lower legs, ankles, feet, rectum.
COCCYX SPINAL NERVES
- controls and regulates: rectum
