PPT-Characteristics of Skeletal Muscle Contraction

Dr Tamara Alqudah Aim of the experiment Learn some of the characteristics of skeletal muscle contraction Simple muscle twitch Summation Tetanization Fatigue Treppe phenomenon Muscle twitch. 1. The six functions of the muscular system are to . 1 produce movement, . 2 maintain posture, . 3 stabilize joints, . 4 generate heat, . 5, store nutrients,. 6 protect body openings. What are three types of muscle tissue?. Muscle Tissue Characteristics. Contractile. Made of contractile proteins. Cells are called fibers. Skeletal Muscle. 40% of body weight. Under voluntary control; attached to skeleton. Striated, or banded, appear. 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. Skeletal & Cardiac excitation . & contraction.

Muscle Group. Major Location. Major . Function. Mode of Control. Skeletal Muscle. Attached to bones and skin of the face. Produces body movements and facial expressions. As it contracts it . -causes movement. -maintains posture. -stabilizes joints. -and generates heat. . Muscle Types. Skeletal muscle (voluntary). muscle attached to the skeleton. cells are long, striated, and multinucleate. I. Functions of Muscular Tissue. Like nervous tissue, muscles are excitable or "irritable”. they have the ability to respond to a stimulus. Unlike nerves, however, muscles are also:. Contractible. . 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. perfomance. enhancing drugs?. 2. Would . you consider supplements such as . Creatine. to be a performance enhancing drug? Why or why not?. The Muscular System. A&P Fall 2016. I. Overview of Muscle Tissues. Chapter 5: The Muscular System. The three major categories of muscle fibers are:. Skeletal . Smooth . Cardiac . Muscle Tissue. Skeletal Muscle (striated / voluntary muscle). Attached . to bones . and are largely . Produce movement. Maintain posture. Stabilize joints. Generate heat. The Muscular System. Muscles are responsible for all types of body movement. Three basic muscle types are found in the body. Skeletal muscle. The Muscular System. Muscles are responsible for all types of body movement.
