------------------------------------------------- LIST OF MUSCLE INJURIES Properly functioning muscles perform only one duty‚ contraction. Muscles enable the body to sit‚ to move and to stand upright. They are attached by way of tendons to bones. Their contraction is controlled by electrical signals that can either be voluntary‚ such as when a person decides to stand up‚ or involuntary‚ as with the muscles that expand and contract the chest to control breathing. Muscles are made of thousands of muscle fibers. Knowing the types

Cardiac This is an involuntary muscle‚ found solely in the walls of the heart‚ as well as in the walls of the blood vessels. This sort of muscle has similarities with the skeletal muscles‚ because it is striated. Furthermore‚ it has slight similarities to the smooth muscles‚ because its contractions are not under conscious control. On the other hand this type of muscle is highly specialised. It is under the control of the autonomic nervous system‚ however‚ even without nervous imput contractions

organization of tissues into organs. The structures and functions of organs determine their relationships within body systems of an organism. Homeostasis allows the body to perform its normal functions. Explain how the muscular/skeletal system (skeletal‚ smooth and cardiac muscles‚ bones‚ cartilage‚ ligaments‚ tendons) works with other systems to support the body and allow for movement. Recognize that bones produce blood cells. For this unit you will submit all assignments through your shared “Flipped Resources”

When it comes to muscle contraction‚ contraction takes place in the muscle fibers. Muscle fibers are the basic building blocks of the muscle and what allow muscles to contract. They appear as long cylinder cells that contain several nuclei. Contraction happens when the muscle receive signals from the nervous system and the Neuromuscular Junction obtains the muscular exchange where the synaptic bulb and the muscle fibers connect. muscle fibers are composed of myofibrils‚ which contain contractile

We have more than 600 muscles in our bodies. They pump blood throughout your body‚ and help you lift heavy things like backpacks‚ and textbooks. You could control some of your muscles‚ while others like your heart‚ have their own jobs without us thinking at all. Muscles are all made up of same material. A type of tissue like the material in a rubber band. Thousands or tens of thousands of small fibers make up all or each muscle in our body. There are different muscles‚ fibers‚ and contractions.

The Skeletal System The skeletal system is made up of bones‚ the joints where bones meet‚ and the connective tissues called cartilages that hold the bones together. The human skeleton is made up of 206 bones‚ and can be divided up into to two parts‚ the Axial Skeleton and the Appendicular Skeleton. (Adams et al.‚ pg. 4)(Boundless‚ 2013) Axial Skeleton The axial skeleton forms the main axis or core of the skeletal system. It consists of the skull‚ vertebral column‚ and thoracic cage. As noted by
