Introduction . The cardiac muscle forms the muscular wall of the heart that is it forms the myocardium.. Some of the cardiac muscle is also present in the walls of the aorta, pulmonary vein and superior vena cava.. 11.2. Learning Objectives. Explain the sliding filament mechanism. State what evidence supports the sliding filament mechanism. Explain where the energy comes from for muscle contraction. Success Criteria. Composed of cells that are highly specialized to shorten in length by contractility.. Made up of cells that are called . myocytes. .. Elongated in one direction (muscle . fibres. ).. Special Terms. Plasma Membrane . Neurotransmitter must stimulate muscle.. This happens at the neuromuscular junction.. Axon of neuron,. ‘Synaptic bulb’. Muscle. AcH. Formed by. Muscle fiber. membrane. The space = synapse, synaptic. Learning Objectives. List . the four traits that all muscle types have in common.. Demonstrate . and explain the use of antagonistic muscle pairs.. Describe . the attachment of muscle to bone and how it leads to movement.. :. Muscular System Functions. Body movement. Maintenance of posture. Respiration. Production of body heat. Communication. Constriction of organs and vessels. Heart beat. Properties of Muscle. Contractility. Tony Serino, Ph.D.. Muscle: Topic Objectives. Be able to describe and compare the types of muscle tissue and their histology. Be able to list and infer the functions and attributes of muscle tissue to physiological needs of the body. Sarcomere shortening and muscle fiber stimulation produce tension . Individual muscle cells surrounded and tied together by connective tissue . Tension . when muscle cells contract, they pull on collagen fibers, producing an active force. Same principles apply to contraction of a single fiber and a whole muscle. Contraction produces tension, the force exerted on the load or object to be moved. Review Principles of Muscle Mechanics. Contraction does not always shorten a muscle:. matt.velkey@duke.edu. 452A Davison, Duke South. Muscle Tissue. I. Striated Muscle - regularly arranged contractile units. A. Skeletal Muscle - long, cylindrical multinucleated cells with peripherally placed nuclei. Contraction is typically quick and vigorous and under voluntary control. Used for locomotion, mastication, and phonation.. Types of muscle tissue: . There are 3 types of muscle tissue found in an animal body. However, they are the Biological motors that convert chemical energy into mechanical & translate the signals from the CNS into movements.. Prof. Dr. . Anna L. Kiss . Department. of . Anatomy. , .
