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

A contraction in skeletal muscle is caused by specialized intracellular thin and thick filaments‚ actin and myosin‚ sliding past each other. Contraction and relaxation of skeletal muscle bring about body movements. These body movements are voluntary and facilitated by the somatic nervous system. Near contact between somatic motor neurons and the muscle fibers are referred to as neuromuscular junctions. It is at the neuromuscular junctions that neurons are able to transmit a signal to the muscle fibers

Skeletal System Study Guide – Use the lecture folder to help you answer these questions. The more detail you add‚ the better prepared for the test you will be. 1. What are the functions of the skeleton? Support & Protection‚ Body Movement‚ Hemopoiesis‚ Mineral Storage 2. What is the difference between osteoclasts and osteoblasts? Osteoblast are cells that generate bones‚ osteoclasts are cells that destroy bone. 3. How many bones do we have in our body? 206 4. What do bones need in order

As the evolution of animals has evolved‚ the organization and function of internal body structures has increased in complexity. As a result‚ the process of homeostasis has taken the role of maintaining the body’s ability to properly function. Homeostasis is defined as a process in the body that attempts to stabilize and maintain a constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibrium. This action primarily aims to preserve

Muscular Disorders Case Report Case: A mother presents with her 13 y/o son with a history of frequent falls‚ difficulty getting up from a lying or sitting position‚ trouble jumping‚ large calf muscles and poor grades in school. Based on the description and symptoms given‚ the likely diagnosis would be Duchenne’s muscular dystrophy‚ or DMD; although DMD and its symptoms tend to show up at an earlier age but not always. This type of muscular dystrophy is the most common and severe form of

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

Homeostasis What is homeostasis? Homeostasis is the mechanism in our body that regulates and maintains a stable and constant environment. This enables our body to respond to changes in the environment around us as. The homeostatic mechanisms in our body‚ observe and monitor conditions and will then make a judgment whether to change the way the body functions is order to adapt to the outside surroundings better. The main organs involved in homeostasis are; the brain‚ liver‚ skin and kidney’s.
