Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

The Physiology of Fitness Assignment 1 Helpsheet Step 1 You need to introduce your assignment‚ here I would define two key terms for the entire of this assignment these are chronic and acute. Example Answer There are many changes to the body during exercise; these can be classified as acute and chronic. Acute meaning they are short term and happen almost instantly with the onset of exercise. The other chronic is long term and allows the body to adapt its capabilities so therefore it

“Osteoarthritis” The Musculo-skeletal system FACT SHEET The term "joint" refers to the physical point of connection between two bones. There are numerous joint types throughout the body‚ these being ball and socket joints‚ hinge joints‚ condyloid joints‚ pivot joints‚ gliding joints‚ and saddle joints. A normal joint meets the point of two bones to permit movement. Cartilage is made up of protein that covers the end of bones and aids in protecting the bones and operates as a shock absorber and

The Human Skeletal System Introduction The human skeletal system is comprised of both fused and individual bones; supported and supplemented by ligaments‚ tendons‚ muscles and cartilage. The skeletons purpose is to protect and support the delicate internal organs and provide a framework that allows the body to stand upright and move. It also produces blood cells and stores minerals that our body needs to function effectively. The skeletal system is a very important part of the human body. Without

valuable when additionally talking about weakness. A basic thought to recollect is that muscle compression is because of a particle called ATP (adenosine triphosphate). ATP must be available for muscles to contract. There are three frameworks of energy that create ATP: Phosphocreatine system‚ the glycolytic system‚ or the oxidative system. On the off chance that exhausted‚ it must be renewed if additional muscle withdrawal is to proceed. Since we are talking about ATP Pathways‚ I needed to additionally

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

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

What is exercise physiology? Exercise physiology is the science that describes‚ explains and uses the body’s response to exercise and adaption to exercise to maximise human physical potential. Exercise physiology is very important in touch because the amount of physical activity our body can tolerate‚ the better we will play for the longest amount of time. ATP/CP system is used by the body to produce ATP quickly in the absence of oxygen. High intensity activities lasting for less than 10 seconds
