Parts and Functions of the Eyes Cornea : The cornea is the outer covering of the eye. This dome-shaped layer protects your eye from elements that could cause damage to the inner parts of the eye. There are several layers of the cornea‚ creating a tough layer that provides additional protection. These layers regenerate very quickly‚ helping the eye to eliminate damage more easily. The cornea also allows the eye to properly focus on light more effectively. Those who are having trouble focusing their

Compare and contrast xylem tissue and phloem tissue‚ including their respective structures and functions. The stems and roots of plants contain two separate transport systems; xylem vessels and phloem tubes‚ of which neither transport oxygen as it is transported to cells by diffusion. The network of xylem vessels transports water and mineral ions from the roots to all other parts of the plant whereas phloem tubes transport food made in the leaves to all other parts of the plant. In the stems

------------------------------------------------- Cell phones Imagine being able to talk to someone that is across the world with a push of a button. Seems a little far-fetched? Well‚ there is such a device that allows you to do that. It is called the cell phone. Cell phones are devices that enable people to talk to others no matter how far away they are from each other. They can be on opposite sides of the planet and they still will be able to talk to each other. Many people nowadays use cell phones very frequently for

dual-function gland‚ having features of both endocrine and exocrine glands. The part of the pancreas with endocrine function is made up of approximately a million[3] cell clusters called islets of Langerhans. Four main cell types exist in the islets. They are relatively difficult to distinguish using standard staining techniques‚ but they can be classified by their secretion: α cells secrete glucagon (increase glucose in blood)‚ β cells secrete insulin (decrease glucose in blood)‚ delta cells secrete

Cognitive Function and the Brain The brain has a major role in the area of cognition. Everything from emotion‚ problem solving‚ language‚ the way we process and categorize memories‚ and how we learn all stem from the functioning of the brain. This paper will discuss the role of the brain in cognitive functions and describe the impact that Phineas Gage’s accident had on revealing the brain’s role in cognitive function. Anatomy of the Brain Cognitive functions derive from the area of the brain

of cells and their ultra structure The cell is the basic unit of life. Each cell can be regarded as a metabolic compartment‚ a separate place where the chemical processes of that cell occur. Cells are often designed to perform a particular function. Depending on that function‚ each cell type has an internal structure that suits it for its job. This is known as the ultrastructure of the cell. There are different types of cells inside the human body. They are the epithelial cells‚ muscle cells‚ nerve

ROD CELLS Rod cells‚ or rods‚ are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor‚ cone cells. Rods are concentrated at the outer edges of the retina and are used in peripheral vision. On average‚ there are approximately 125 million rod cells in the human retina.[1] More sensitive than cone cells‚ rod cells are almost entirely responsible for night vision. STRUCTURE AND FUNCTION Rods are a little longer and leaner
