Groups are given 5 minutes per station. The Muscular System: Muscle Metabolism 1. Eventually, oxygen is depleted, and aerobic respiration stops. Some joints of the human body are weak and require the support of the muscular system to achieve stability. Muscular System Anatomy and Physiology Lecture Powerpoint Purpose: This Powerpoint lecture dissects a single muscle into the individual fascicles and fibers that it is made of. There are also two types of muscles are in the body; voluntary and involuntary.
This type of muscle can be found in internal organs like your stomach or arteries. Several major metabolic pathways are involved, some of which require the presence of oxygen. In the muscle there are 2 flexible hinge like regions. This dissection guide helps students to locate and identify some of these important muscles. Second, the names, locations, and actions of the major surface muscles of the human body are reviewed.
When you muscle contracts they attach themselves and provide a contractile force. Smooth muscle is involuntary, this means that it is under control of the autonomic nervous system. Station 1: Muscular System, Skeletal Muscle, 3 Types of Muscle, Cardiac Muscle, Smooth Muscle Station 2: Anatomy of Muscle, How a Muscle Works, Muscle to Tendon to Bone, Opposite Contract Station 3: The Muscles. The Krebs cycle and oxidative phosphorylation 5. The ones which we can move are the voluntary muscles; the ones which move on their own, like the heart, are involuntary muscles. Skeletal muscles are very important for such joints. Students take notes using the last section of the , which is designated for notes.
The heads move and store potential energy in their new position. Through the metabolic process of glycogenolysis, glycogen is broken down to release glucose. This study guide can be used as a source of evidence by students when completing their assessment at end of lesson. Tendons or collagen fibres attach skeletal muscle to the bones in the body. They help to regulate digestion and blood pressure. Most of the muscle in the body is , which is muscle that only moves bones. These contain even smaller structures called actin which is a thin, contractile protein filament, containing 'active' or 'binding' sites and myosin filaments which are a thick, contractile protein filament, with Myosin Heads.
In what way do tendons and ligaments differ? See the fact file below for more information on theÂ Muscular System or alternatively, you can download our 22-page Muscular System worksheet pack to utilise within the classroom or home environment. Adults have a certain fixed number of muscle cells, approximately 602. Students will learn how the individual protein filaments within a muscle fiber work together to produce a contraction. Muscular System Muscular System Worksheets This is a fantastic bundle which includes everything you need to know about Muscular System across 22 in-depth pages. The Muscular System The human body has about 640 muscles. Each muscle fibre is made up of smaller fibres called myofibrils.
Muscular System: Muscle Metabolism 1. First, the internal and microscopic anatomy of a single muscle is related to the actual physiology of a muscle contraction. Muscles have the ability to contract actively to provide the force for movement. Name two sources of oxygen: 1. Skeletal muscle is under voluntary control.
Signficant coverage is also given to the brain and spinal cord. They would have to rely on gravity and momentum o get through the body parts it needs to. Muscular System Student Notes Outline Purpose: Taking efficient notes can be a big challenge for many students, especially when working from a Powerpoint lecture. These filaments slide in and out between each other to form a muscle contractions, this is why it is known as the sliding filament theory. Structurally, these muscle fibers appear striated striped when magnified, have more than one nucleus, and may be up to 30 cm long in humans. The last type of muscle is cardiac muscle which is only found in the heart. Pyruvic acid If oxygen is not available, pyruvic acid is converted to lactic acid, which is the end product of anaerobic respiration.
Each has its own distinctive function, and therefore, its own distinctive structure, but all muscles allow movement of some kind. These muscles produce strong contractions. A motor neuron ends in a synapse with a muscle fiber. The immediate, short-term, and long-term energy sources available to muscle tissue are also covered. To download this worksheet, click the button below to signup for free it only takes a minute and you'll be brought right back to this page to start the download! It is an involuntary muscle which means it also works under the control of the nervous system, it works continuously. . Most of the muscle in the body is skeletal muscle, which is muscle that only moves bones.
The contraction of skeletal muscles is one of the most energetically expensive activities that the body does on a regular basis. Cardiac muscle is only found in the wall of the heart. Most lactic acid diffuses out of the cell and into the bloodstream and is subsequently absorbed by the liver. Small motor units fewer myofibers. The last type of muscle is muscle which is only found in the. Each student is responsible for completing a. The questions and vocabulary are roughly written in the same order as they appear in the lecture.
Physiology: Contraction of Motor Units p. List the two sources of glucose: 1. As previously mentioned, the heart is an involuntary. In order to do that, a lot of the oxygen the body is now taking in does the conversion instead of being used elsewhere. Essential Concepts: Skeletal muscle, joints, tendons, ligaments, cartilage, osteoarthritis, flexors, extensors. Heat produced by muscles is important in cold climates and for normal function. If oxygen is available, the.
