The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.
There are many billions of nerve cells, also called neurons, in the nervous system. The brain alone has about 100 billion neurons in it. Each neuron has a cell body and various extensions. The shorter extensions (called dendrites) act like antennae: they receive signals from, for example, other neurons and pass them on to the cell body. The signals are then passed on via a long extension (the axon), which can be up to a meter long. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
A freezing probe or a medical laser can be used by your doctor to seal any tears or fractures in your retina if you have a small hole or tear in it. These procedures are typically available in an eye doctor's office.
It can be difficult to adjust at first to living with retinal detachment's symptoms. Treatment is accessible, but how quickly it occurs and how much harm has already been done can affect how successful it is. But after retinal detachment surgery, the majority of patients are able to live freely and see clearly.
what is Retina?
Retina is the term for the light-sensitive layers of nerve tissue at the part of the eye that capture images and transmit them to the brain as electric signals.
A layer of photoreceptor cells in the retina convert light into information. In essence, these are light-sensitive cells that can recognise characteristics like colour and light intensity. The information acquired by the photoreceptor cells is processed in the retina and transmitted to the brain via the optic nerve.

Answer:
Sodium electrolyte
Explanation:
Sodium is a very much essential electrolyte that is required by the human bodies. This directly influences the amount of water present in the human body, including the water that either retains in the blood or are eliminated through the urine. Within the body sodium reacts with water and it helps in maintaining the fluid quantity both inside the cells as well as on the outside of the cells. Consuming lesser amount of sodium helps in the retention of water in the body. Sodium electrolyte is helpful in growing proper body muscles and functioning of the nervous system.
Hence, the correct answer is sodium electrolyte.
Oral exam, vision and hearing screenings, sports physicals and testing for scoliosis are some of the preventive care taken for better health.
All anatomical terms have a <em>"reference"</em> point which is called the <em>"anatomical"</em> position. This is a <em>"body"</em> position where you<em> "stand"</em> up, head straight and <em>"arms" </em>by your <em>"side" </em>with the palm of your<em> "hands"</em> facing forward.
