@officialinsideus: Skeletal muscle: This type of muscle creates movement in the body. There are more than 600 skeletal muscles, and they make up about 40% of a person's body weight when the nervous system signals the muscle to contract. Groups of muscles work together to move the skeleton. These signals and movements are nearly involuntary. Paramecium is a slightly thicker layer of connective tissue consisting mainly of tai pi and eye collagen and surrounds a group of fibers. This fiber group is referred to as a physical or bundle physical or the functional units of skeletal muscle tissue. The Paramecium contains slightly larger blood vessels and nerve fibers than those traveling through and dome ism. FMC surrounds the entire collection of physicals making up an individual muscle. This dense connective tissue made up of mainly Type II collagen contains the neurovascular supply to the muscle. Cardiac muscle. The cardiac muscle is an involuntary muscle. This type makes up the walls of the heart and creates the steady, rhythmic, pulsing that pumps blood through the body from signals from the brain. This muscle type also creates the electrical impulses that produce the heart's contractions, but hormones and stimuli from the nervous system can also affect these impulses, such as when your heart rate increases when you're scared. The MYO filaments of cardiac muscle are arranged in a similar pattern to the skeletal muscle resulting in cross striations. The fibers are crossed by linear bands called interconnect disks. These structures have two important roles. Smooth muscle is involuntary and also contracts in response to stimuli and nerve impulses. Muscle movement happens when neurological signals produce electrical changes in muscle cells During this process, calcium is released into the cells and brings about a short muscle twitch. #biology #medical #Science #anatomy #muscles #smoothmuscles #cardiacmuscles #cardiology #heart #heartmuscles
