Articles: The Human Body
With regard to living things, a body is the integral physical material of an individual, and contrasts with soul, personality and behavior. In some contexts, a superficial element of a body, such as hair may be regarded as not a part of it, even while attached. … Read more
Muscle is one of the four tissue types. The other three types are: epithelium, connective tissue and nervous tissue. The primary purpose of muscle tissue is to contract. Muscle contraction is used to move parts of the body, as well as to move substances within the body. … Read more
Bone is a connective tissue and organ, found in many animals. Bones are used to support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; they are also involved with cell formation, calcium metabolism, and mineral storage. … Read more
The skeleton or skeletal system is the biological system providing support in living organisms. An internal skeletal system consists of rigid structures within the body, moved by the muscular system. If the structures are mineralized or ossified, as they are in humans and other mammals, they are referred to as bones. … Read more
The median nerve is a nerve that runs down the arm and forearm. It is one of the five main nerves originating from the brachial plexus.
The median nerve is formed from parts of the medial and lateral cords, and continues down the arm. … Read more
Ligaments and tendons are forms of fibrous connective tissue.
A ligament is a short band of tough fibrous connective tissue composed mainly of long, stringy collagen molecules. Ligaments connect bones to other bones in joints. … Read more
What Are the Structures of the Shoulder and How Does the Shoulder Function?
The shoulder joint is composed of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) (see diagram). … Read more
The connective tissues serve many purposes in the body:
· They provide structure.
· They serve as packing.
· They provide insulation, and
· They are one medium for the defense of the body. … Read more
The neck is the part of the body on many limbed vertebrates that distinguishes the head from the torso or trunk. An anatomical description of the human neck follows.
Anatomy of the (human) neck
In the middle line below the chin can be felt the body of the hyoid bone, just below which is the prominence of the thyroid cartilage called “Adam’s apple,” better marked in men than in women. … Read more
Fascia is the semiflexible fibrous membrane of connective tissue that binds together the various components of the body. Pockets in the fascia contain the various organs of the body.
The myofascia covers, supports and separates the skeletal muscles. Each muscle fiber is wrapped with myofascia, bundles of those fibers are wrapped with myofascia, and the whole muscle is also wrapped in myofascia. Myofascial tissue is dynamic: under strain it increases in density and relative rigidity, giving the muscles more support
In healthy non-fibrotic fascia, collagen fibers are cross-linked to a degree that creates stability. … Read more
