Somatic cells are all the cells that make up an organism, including the organ, muscle, fat, bone, and skin cells. The only exceptions are the egg and sperm cells, also called germ cells, which are involved in sexual reproduction. Although somatic cells differ greatly in their form and func...
Muscle consists of many individual muscle fibers – long, cylindrical cells made of a bundle of myofibrils, filaments arranged in segments known as sarcomeres. Muscle Fiber Structure If you imagine the cross-section of a muscle, you would see bundles of fibers known as fasciculi, which are su...
Skeletal muscle tissue, the most common kind of muscle tissue in humans and other large animals, has striations, or grooves, that mark out each individual muscle cell. These cells, sometimes called muscle fibers, extend the length of the muscle. This is necessary for the cells to perform ...
”. The medical students ask many great questions. They are always interested in clinical applications. The goal of today’s article is to help you have a much clearer understanding of stem cells.
What controls the skeletal-muscle system? What structures connect the individual heart muscle cells? What muscles attach to the scapula? What are muscle cells called? What are the three basic types of muscle found in the human body? Which type of muscle causes voluntary movement?

An autoimmune disease causes your body's immune system to attack healthy cells in your body by mistake. Antibodies are created by your body to destroy foreign substances that can be harmful to you. An autoimmune disease causes the antibodies to attack healthy cells instead of foreign substances....
A diagram showing the composition of a blood vessel. Smooth muscle cells are found in the tunica media. Like a skeletal muscle, the contraction of a vascular smooth muscle is controlled by the nervous system. Unlike skeletal muscles, which are voluntarily controlled, vascular smooth muscles are ...
