Definition. The muscular system is a set of tissues in the body with the ability to change shape. Muscle cells connect together and eventually to elements of the skeletal system. When the muscle cells contract, force is created as the muscles pull against the skeleton.
Oct 30, 2023 · The shape or form of muscle is generally dependent on its fascicular architecture and fiber length which also helps to define the muscle’s function e.g. some muscles, such as the gluteal muscles, have numerous thick, short fascicles, while others such as the sartorius muscle have a lesser amount of long and relatively slender fascicles. These differences in muscle shape and fiber arrangement ...
The Musculoskeletal System. The muscular system is made up of muscle tissue and is responsible for functions such as maintenance of posture, locomotion and control of various circulatory systems. This includes the beating of the heart and the movement of food through the digestive system. The muscular system is closely associated with the ...
Muscle is one of the four primary tissue types of the body (along with epithelial, nervous, and connective tissues), and the body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle (Figure 33.1). All three muscle tissues have some properties in common; they all exhibit a quality called excitability as ...
Dec 8, 2017 · Function of Muscle. Whether it is the largest muscle in your body or the tiny muscle controlling the movement of your eye, every muscle functions in a similar manner. A signal is sent from the brain along a bundle of nerves. The electronic and chemical message is passed quickly from nerve cell to nerve cell and finally arrives at the motor end ...
Jan 23, 2024 · The muscles in and around your organs move involuntarily to keep your body working properly. Your heart beating and muscles in your chest and back moving your ribs when you breathe are examples of involuntary movements. Your muscles use a combination of voluntary and involuntary movements to work with nearly all your body’s systems and functions.
The three types of muscle cells are skeletal, cardiac, and smooth. Their morphologies match their specific functions in the body. Skeletal muscle is voluntary and responds to conscious stimuli. The cells are striated and multinucleated appearing as long, unbranched cylinders. Cardiac muscle is involuntary and found only in the heart.
