Limbs

The upper and lower limbs are constructed after a common type, but the different functions for which they have become adapted in man have led to structural differences of a very definite kind. Each limb has a girdle, which connects it to the trunk, and three segments. The terminal segment in the upper limb is the hand and is specially adapted for prehension. In the lower limb the terminal segment is the foot and is primarily adapted to constitute an efficient supporting base for the body in the erect attitude, but it is at the same time constructed in such a manner as to facilitate locomotion.

Skin and Muscles

The body is covered by the skin. This tissue is built of an outer layer of epithelial tissue and an inner one of connective tissue. In the connective tissue are found the blood vessels and nerves which supply the skin.

Just beneath the skin is a layer composed of connective tissue. In some places this binds the skin directly to the bones and in others it separates the skin from the muscles. The subcutaneous fat is found in this layer and is called adipose tissue. The subcutaneous tissue is called fascia.

The skin and the superficial fascia form a protective covering for the muscles, bones and internal organs. The muscles are formed by a mass of muscle cells. The muscle bundles are held together by connective tissue, in which are found the blood vessels and the nerves which supply the muscles.

The covering of the bone is composed of a fibrous connective tissue, called the periosteum to which the muscles are attached, either directly or indirectly, by means of a tough band called a tendon. Whenever a muscle contracts the points of attachment are brought closer together.

Skeletal Muscles.

Skeletal Muscles as Organs of the Muscular System. The skeletal muscles are the organs of the muscular system. They number over 400 in the human body. Each has an arterial, venous, lymphatic and nervous supply as well as a connective tissue framework - the whole constituting an independent unit. However, muscles never act singly but in groups. We seldom contract an individual muscle; we execute a movement and in the performance of that movement whole groups of muscles are involved. Skeletal muscles, then, are not functionally separate and unrelated parts but are grouped into a system which exhibits correlation and cooperation of its parts.

Attachments of Muscles. Each striated muscle consists of a body and two attachments. The body contains the muscular tissue; the attachments are composed of white fibrous tissue. The attachment of muscle to bone may be of one of three types: direct to the periosteum, by means of a tendon, or by means of an aponeurosis. In a direct attachment the white fibers of the connective tissue framework of the muscle fuse with the fibrous layers of the periosteum of the bone. A tendon is a band or cord of white fibrous tissue serving to connect a muscle to a bone. The sarcolemma and the connective tissue surrounding the muscle bundles fuse with the collagenous fibers of the tendon. An aponeurosis is a heavy sheet of white fibrous tissue serving to connect a muscle to a bone or in some instances to connect muscles.

Origin and Insertion. The more fixed attachment of a muscle which serves as a basis of action is called the origin. The movable attachment where the effects of movement are produced is the insertion. Generally the origin is near the spinal axis of the body while the insertion is peripheral.

Muscle Action. If the attachments of a muscle are known, its action may be determined by recalling that the insertion moves toward the origin when the muscle contracts. Muscles are arranged in opposing or antagonistic groups: flexors and extensors, adductors and abductors, internal rotators and external rotators. When the muscles flexing the forearm contract, the muscles which have the opposite effect, the extensors, are thrown into physiological relaxation; elongating and giving way to the movement.
