Activity 1 – The Muscle Twitch and Latent 1) Define the terms skeletal muscle fiber‚ motor unit‚ skeletal muscle twitch‚ electrical stimulus‚ and latent period. Skeletal Muscle Fiber: Skeletal muscle cells that are composed of hundreds to thousands of individual cells that produce muscle tension. These fibers are what move our bodies and generate muscle tension/force that enables us to have manual dexterity. Motor unit: consists of one motor neuron and all of the skeletal muscle fibers that it

organization of tissues into organs. The structures and functions of organs determine their relationships within body systems of an organism. Homeostasis allows the body to perform its normal functions. Explain how the muscular/skeletal system (skeletal‚ smooth and cardiac muscles‚ bones‚ cartilage‚ ligaments‚ tendons) works with other systems to support the body and allow for movement. Recognize that bones produce blood cells. For this unit you will submit all assignments through your shared “Flipped Resources”

I will be describing and explaining the acute immediate effects of exercises on the skeletal and muscular system. There are four main responses to exercise Increased blood supply to the muscles‚ Increased muscle pliability‚ Increased range of movement at joints and Muscle fibre micro tears. Increased Blood supply to our muscles When we are exercising our heart rate increases. During exercise more blood is pumping out of the heart and around the body. When our heart beats faster more blood

ANATOMY AND PHYSIOLOGY The pelvis is a large semicircular bone complex that forms the base on which the torso and upper body are positioned. The pelvis‚ which is a rigid and inflexible portion of the skeleton‚ is built to provide a foundation of the movement of other parts of the anatomy‚ particularly the back and the legs. The pelvis also permits the weight of the entire upper body to be evenly distributed

A motor neuron‚ a nerve ending that is attached to a muscle fiber in Petzold’s huge bicep‚ sends a message to contract. This message goes to the neuromuscular junction‚ which is the connection between the actual nerve fiber and muscle fiber. As the message to contract reaches the terminals a neurotransmitter‚ a chemical messenger for the body‚ is released into the gap between the terminal end‚ and the sarcolemma and motor end plate called the synaptic cleft. The particular neurotransmitter is called

Unit 5: Anatomy and Physiology (P4) Explain the physiology of two named body systems in relation to energy metabolism in the body In this task I am going to discuss the three systems involved in energy metabolism in the body. The chemical equation for cellular respiration is: C6H12O6 + O2 = E + CO2 + H2O OR Glucose + Oxygen = Energy + Carbon Dioxide + Water In order to release energy we need glucose which is a simple carbohydrate that is produced after digestion of food and we also need oxygen
