If you’ve developed an interest for self-massage, it’s important to discuss skeletal muscles. This will help you gain a better understanding of the effects of exercises and the general need for activity.

Muscles are attached to the skeleton. The rib cage and pelvis protect your internal organs. Mother Nature has wisely adapted the skeleton to perform a range of necessary functions. Bones contain marrow and are mostly covered with osseous tissue.
They contain numerous blood vessels, lymph glands, and nerves. Bones are connected with joints that can allow slight or full movement. The flexibility of joints depends on the shape of bones. Our shoulder and hip joints allow very free movement.
Joints of attaching bones are bond by capsules and cartilages. Cavities between joints are filled with synovial fluid.

Muscles can be divided into two groups: skeletal or striated muscle tissue which is under our control and smooth muscle tissue that we cannot control as it forms the inner walls of our internal organs. In addition to these two groups, there’s a muscle that has cross-tissue similar to striated muscles, but has a function resembling smooth muscles. The movements of this muscle cannot and shouldn’t be under our control. It’s the heart.

Muscles reach of one or several joints. This determines their workload. Depending on the task assigned to a muscle, we define it as a bending or stretching muscle. Our musculature works collectively. For example, if we bend our hand from the elbow, muscles on the opposite side stretch. If we extend our hand, these muscles contract.

Muscle tissue is composed of fibers in different lengths that have a very important property – great flexibility, the ability to contract and extend. This tissue forms strands that in turn form a muscle. Muscles come in many shapes and they contain a lot of blood vessels, lymph glands, and nerves.

Everything in this world has a beginning and an end, so do muscles. The tips of muscles are called tendons. Tendons attached muscles to bone.
