ANATOMY & PHYSIOLOGY of the EYE Even though the eye is small‚ only about 1 inch in diameter‚ it serves a very important function -- the sense of sight. Vision is by far the most used of the five senses and is one of the primary means that we use to gather information from our surroundings. More than 75% of the information we receive about the world around us consists of visual information. The eye is often compared to a camera. Each gathers light and then transforms that light into a "picture

2017 Motor Unit Recruitment and Muscle Fatigue Lab Introduction Human skeletal muscles are made up of hundreds of cylindrically-shaped cells called myofibers‚ and they are bound together by connective tissue. These muscles are stimulated to contract by somatic motor nerves‚ or motor neurons‚ that carry signals in the form of nerve impulses from the brain or spinal cord‚ to the skeletal muscles. Although a motor neuron can innervate several fibers‚ each muscle fiber can only be innervated by one

Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS

Chameleons Organism Physiology Brianna Kibler October 1‚ 2014 Principles of Biology BIO/101 Matthew Scholten Organism Physiology We know that an organism is anything that is living and can function by itself. This paper will help understand chameleons and how they have evolved to adapt to their surroundings. It will also discuss their physical features inside and out. Myths and facts will be revealed‚ as well as a few comparisons between sexes. Though there are many species of chameleons
