A. Coordination System
Coordination System And Sense Tool consists of the nervous system and hormones. This coordination system has a function, which regulate the body’s work tools, sehinggan also known as the system of coordination.
1. Nervous System
a. Nerve cells, or neurons, has a composition on nerve cell bodies that are useful to process stimuli, in the bodies sarag cells are dendritic, cell nucleus and cell organelles seagai Nissl bodies and axons were thinking about usability to deliver implus. Based on its function, nerve cells have different 4, namely:
- Afferent sensory neurons or neurons.
- Motor neurons and efferent neurons
- Neuron connector.
- neuron adjustor
b. Glia or neuroglia cells, in the brain there are three kinds of crazy cells, namely:
The nervous system in humans are over:
1. Nerve center comprising the brain and spinal cord.
- Large brain or cerebrum include olfactory lobe or smell or center forward, the occipital lobe or vision center or rear, or center lobe temproalis hearing and taste, parietal lobe or sensory center, adjacent to the association cortex or the crown of the back, lobe paretalis or ubun- front crown, as the motor center, for conscious movement coordination, and the cerebral cortex or outer portion of the brain is great, as the center of consciousness, memory, intellect, will and attitude.
- The midbrain or mesencephalon, optic lobes are the center of the eye pupil reflexes and body balance settings.
- Cerebellum or cerebellum. To the center of balance, motor coordination, and refining movement.
- Medulla oblongata contained between the brain and the spinal cord, its function as a central regulator of heart rate, respiration, dilation and constriction of blood vessels, reflex swallowing, peristalsis Mutah, coughing, and sneezing.
- Spinal cord or spinal cord. Useful to continue the course of the impulse, the center of the foot and hand reflexes, urination and defecation.
B. Abnormalities In Coordination System
1. Parkinson’S Disease
Due to the damage caused to the collection of nerve cells in the lower part of the brain, causing large-herakan unnecessary movements on the parts of the body. For example, the muscles in the arm that sometimes contraction and rekajsasu so that the hand be quivering or tremor. Such damage can also cause sustained contraction of the muscles of the body parts, for example the facial muscles, which causes the face to become stiff so it looks like a mask. Parkinson’s disease attacks the brain stem not so vision, hearing, and intelligence of patients is not compromised.
This headache occurs due to loss of balance and the ability to detect motion and rotation. This balance is generated by the semicircular canal in the form of three semicircular canals located at the base of the cochlea in the inner ear. Each channel is walled semicircular hair cells surrounded by lymph fluid. When our heads tilted, hair cells will move in the opposite direction due to the movement of lymph fluid. This raises umpuls nerves that tell the brain about the body posture position.
When we rolled the body constantly klalu suddenly stopped, for a moment will continue to flow and the lymphatic hair cells continue to send impulses which implies movement. The contradiction between the attitude of the body with impulses or messages are reported to the brain will cause a headache for a while.
3. Nerve Deafness
Nerve deafness caused by damage to the cochlear and Organ of Corti or auditory nerve.
4. Carpal Tunnel Syndrome or CTS
Occurs due to obstructions or blockages in the conduction of nerve impulses in the palm of the hand. Patients usually experience a tingling sensation in the fingers.
