The Nervous System Essay

Sensory neurons are stimulated by sensory organs and receptors that transmit pulses to the spinal cord and brain. Emotions transmitted by sensory neurons include heat, colds, pain, taste, smell, sight, and hearing

Motor neurons transmit impulses from the central nervous system (brain and spinal cord) to muscles and glands to encourage exercise.

When it is possible to stimulate neurons by light or sound, the permeability of the cell membrane to sodium ions varies. Specific sodium gate or channel is open, Na ... shows more

Sound and light are evaluated so that stimulating recipients react in the most appropriate way and adapt to the environment. In order to be able to modify behavior empirically, the brain adjusts physical activity to ensure effective operation and information preservation.

The autonomic nervous system controls the automatic function of the body. These include controlling most of the glands. The heart and organs are controlled by the influence of involuntary muscle meat such as bronchus, gastric artery, intestine

The autonomic nervous system has two parts, the sympathetic nervous system and the parasympathetic nervous system.

Both have the opposite function. For example. The sympathetic nervous system stimulates the rise of the heart rate, and the parasympathetic nerve reduces the heart rate. The sympathetic nervous system mainly uses neurotransmitter adrenaline, and the parasympathetic nervous system acts via chemical acetylcholine.

5. Explain at least two neurological diseases / symptoms. How to use aromatherapy to help these diseases

Epilepsy is a disease that affects the central nervous system. Chaotic electrical activity squirting in the brain causes seizures, which may be partial or cause loss of consciousness. There are many reasons for epilepsy including birth injuries.

The nervous system is involved in neural coordination. The nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system occupies most of the nervous system including the brain and spinal cord and plays an important role in controlling behavior along with the peripheral nervous system (PNS). The nervous system communicates with several other body systems. Example: Even if we have not started eating yet, our brain will begin to convey our digestive organs, pancreas and stomach through the nerve expected to enter the food. Due to this stimulation, the pancreas stimulated by the neural signal shows a total secretion of about 20%. Skeletal muscle also requires neural input to initiate contraction

Cells including the central nervous system and the peripheral nervous system are classified as nerve (or nerve) tissue. In the central nervous system, nerve tissue forms the brain and spinal cord. In the peripheral nervous system, nerve tissue forms cranial nerves and spinal nerves including motor neurons. Epithelial tissue is formed by cells covering the surface of organs, such as the surface of the skin, the respiratory tract, the reproductive tract, and the lining of the digestive tract. Since the cells containing the epithelial layer are connected by semipermeable tight junctions, this tissue provides a barrier between the external environment and the organs it covers. In addition to this protective function, epithelial tissue can also be used exclusively for secretion, excretion and absorption. Epithelial tissue helps protect organs from microbes, injuries, fluid loss

A special part of the nervous system is the intestinal nervous system responsible for controlling digestive organs. A part of the autonomic nervous system overlaps with the intestinal nervous system. Since the intestinal nervous system is a nervous tissue of gastrointestinal organs, it is found only in the periphery. In 2003, with the findings on magnetic resonance imaging (MRI), the Nobel Prize for Physiology and Medicine was awarded to Paul C. Lauterbur and Sir Peter Mansfield. This is a tool that allows you to see the body structure (not just the nervous system) dependent on the magnetic field associated with a particular nucleus. The application of this technology in the nervous system is that adipose tissue and water show different shades between black and white. White matter is (fat derived from myelin), gray matter is not fat, so it can easily be distinguished in MRI images.
