muscle tissue: skeletal‚ smooth‚ and cardiac. Skeletal muscle was investigated in this lab. Skeletal muscle is composed of two filaments called actin and myosin‚ which run parallel to each other. Actin has a protein that run along it called tropomyosin‚ that prevents actin from binding to it‚ unless calcium is bound to a part of the tropomyosin called troponin. Sets of actin and myosin filaments are divided into individual units called sarcomeres. Sarcomeres are what gives skeletal muscle tissue its

Great job once again on answering the question about how muscle action relates to the movement. I think maybe I took it to the extreme‚ I went on about agonist‚ synergist‚ and antagonist muscles. I wasn ’t sure if I should add the levers too. It appears as though you explained every type of muscle movement and gave an example of each. I went into flexion at the elbow and discussed that the agonist is the main muscle mover‚ the antagonist does the opposite‚ and the synergist is the helper. However

Muscles are responsible for all conscious and unconscious movement. It is how we move and react to an environment. There are three types of muscles in the body include the skeletal muscle‚ smooth muscle‚ and the cardiac muscle. Whether you are running‚ walking‚ breathing‚ eating‚ sleeping‚ or typing it all involves some sort of muscle action. Muscle cells that shape‚ form‚ and outline the whole human skeleton is called a muscle fibers. There are two types of muscle fibers: Type I (slow-twitching

REVIEW SHEET EXERCISE 2 Skeletal Muscle Physiology NAME: Jasmine Young LAB TIME/DATE: 1. Define each of the following terms: • motor unit - A motor unit consists of a motor neuron and all of the muscle fibers it innervates. • twitch - Skeletal Muscle twitch is the mechanical response to a single action potential. It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane

Skeletal dysplasias are a group of disorders characterized by abnormalities in the growth and remodeling of cartilage and bone. These dysplasias affect the skull‚ spine‚ and extremities. Achondroplasia is the most common type of skeletal dysplasia. It is a genetic condition that results in abnormally short stature with disproportionately short limbs. It occurs in about 1 in every 15‚000 to one in 40‚000 births. In approximate 80% of the cases‚ it is caused by a spontaneous mutation to the FGFR3 gene

Overview of Planning OVERVIEW This toolkit is an overview of the different aspects involved in planning for an organisation or project. It should enable the user to make a clear distinction between strategic planning and action planning‚ both of which are dealt with in detail in separate toolkits. It also provides some ideas about techniques to use in planning. It should provide a fairly inexperienced planning team in any organisation with a clear picture of what planning should involve‚ and of
