Optic Nerve The optic nerve is located in the back of the eye and is also called second cranial nerve and cranial nerve II. the optic nerve is to transfer visual information from the retina to teh vision centres of the brain via electrical impulses. It is made up of ganglionic cells or nerve cells and consists of more than 1 million nerve fibres . Our blind spot is caused by the absence of specialised photosensitive/light-sensitive cells or photoreceptors; the part of the retina where the optic

Addition and Subtraction of Integers Addition of Positive Integers Consider the addition of 2 + 3. The plus sign‚ +‚ tells us to face the positive direction. So‚ to evaluate 2 + 3‚ start at 2‚ face the positive direction and move 3 units forwards. This suggests that: Positive integers can be added like natural numbers. Addition of Negative Integers Consider the addition of (–2) + (–3). The plus sign‚ +‚ tells us to face the positive direction. So‚ to evaluate

understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons. We used the sciatic Lithobates pipiens nerve in this experiment‚ the sciatic nerve is long nerve‚ it extends from the buttocks

For my science fair project‚ I figured out what solvent would work best to erase permanent marker. The solvents I tested were: lemon juice‚ vinegar‚ water‚ and rubbing alcohol. I tried each of these solvents on a permanent marker line on plastic‚ paper‚ fabric‚ and wood. In this research paper‚ I will be talking about what a permanent marker is‚ how they are made‚ why they work so well‚ what rubbing alcohol is and its common uses‚ what vinegar is and its common uses‚ what water is and why water is

Neurophysiology has been a subject of study since as early as 4‚000 B.C. In the early B.C. years‚ most studies were of different natural sedatives like alcohol and poppy plants. In 1700 B.C.‚ the Edwin Smith surgical papyrus was written. This papyrus was crucial in understanding how the ancient Egyptians understood the nervous system. This papyrus looked at different case studies about injuries to different parts of the body‚ most notably the head. Beginning around 460 B.C.‚ Hippocrates began

due to dust. Other impacts can have permanent consequences. Pollution effects are not confined to the environment. The potential for damage to historical monuments has already been realized. Some damage‚ such as from wind or rain‚ is unavoidable. However‚ pollution contributes additional risk factors that can increase the level of destruction. The effects may be minor‚ such as a blackening of the surface of monuments due to dust. Other impacts can have permanent consequences. Pollution effects are
