Christopher Couchell Muscle Physiology Purpose: The Purpose of this exercise is to understand how muscle twitch‚ contract and react to different activities. Exercise 1: Muscle Twitch A. What is a muscle twitch? A muscle twitch is the fasciculation ‚ or "muscle twitch"‚ is a small‚ local‚ involuntary muscle contraction and relaxation visible under the skin. B. According to the graphs‚ which muscle has the fastest twitch? Why? The lateral rectus eye muscle has the fastest twitch. It

Moral Muscle can be defined as pushing ourselves to do more than the minimum in our moral life. Moral Muscle is not just having physical strength but metal strength. The phrase Moral Muscle is a metaphor in which shows a type of strength someone obtains mentally. Someone who exercises his or her moral muscles has an mindset to do the right thing. Someone is considered to have moral strength when they restrict themselves from doing bad things and in place of that commit good thing. Moral strength

many different types of bone fractures. Also‚ you can have them any where in your body. You can have them in your arm‚ leg‚ wrist‚ skull‚ and many other places. If you fracture a bone and it doesn’t break through the skin it is called a closed fracture. The opposite of a closed fracture is when the bone breaks through the skin; it is called an open fracture. When there are organs that are injured‚ such as the lung‚ it is called a complicated fracture. Sometimes‚ the bone splinters into pieces

“An Echo in the Bone” by Denis Scott On May 1974‚ the first performance of Dennis Scott’s An Echo in the Bone was staged by the Drama Society at the University of the West Indies Mona campus in Jamaica. The play deals with the destructive impact slavery has left on the history of Afro West Indians. Scotts aim‚ through this play‚ is to reclaim and recreate the past lost to our ancestors as well as the voice taken from them‚ that merely stands today as an echo in the bone. Though he aspires

to describe how the human body reacts to changes and keeps itself within certain parameters to ensure that it can function correctly. These reactions include a range of responses‚ from the release of hormones to regulate internal imbalances to sweating to lower body temperature. Homeostasis is the process used by the body to maintain a stable internal environment. Either negative feedback or positive feedback can be used in homeostasis. In negative feedback‚ the body changes an internal condition

Muscle fatigue is weakness or weariness resulting from exertion or prolonged stress and the failure to maintain an expected power output. (Amussen) The process by which your body produces energy is called glycolysis. During glycolysis‚ glycogen is broken to produce creatine phosphate‚ which releases energy. The energy released catalyzes a reaction to produce ATP. The ending product of glycolysis is lactic acid‚ which is created by breaking pyruvate acid down. Then lactic acid is broken down to produce

Humans breathe and speak daily without a thought of what really goes into this one aspect of communication. Even though breathing and speaking may seem like a mindless process‚ there are a number of muscles‚ ligaments and body parts that go into the mechanisms that make life what it is. In order to live and speak‚ we must be able to breathe. Respiration is the act of breathing. The act of drawing in a breath‚ or inspiration is the process of in-taking air. Air is taken in through the upper airways

from that occurs gives rise to voltage of waveforms. With the human body each cell at this present time is generating electrical impulses like a voltage generator‚ which is a basic source of all the bioelectric potentials. With these bioelectric potentials they produce ionic voltages produced by the coordination of electrochemical activity within numerous cells. When the cells are in line the charges tend to migrate through the body fluids towards the still unexcited cell area. As the charge migrates
