Structure & Function of the Skeletal System
Consist of: bone, bone marrow, cartilage, joints, ligaments, synovial membrane, synovial fluid, and bursa
-bones act as the framework
-bones support and protect the internal organs
-joints work in conjunction with muscle, ligaments, and tendons, making possible the wide variety of muscle movement
-calcium, which is required for normal nerve and muscle function, is stored in bones
-red bone marrow, which has an important function in the formation of/ blood cells, located within spongy bone
The structure of bone
bone is the form of connective tissue that is the second hardest tissue in the human body. only dental enamel is harder than bone
Anatomic landmarks of bone
diaphysis- the shaft of a long bone
epiphyses- the wider ends of long bones such as femurs of the legs.
Foramen- an opening in a bone through which blood vessels, nerves, and ligaments pass.
Process- a normal projection on the surface of a bone that most commonly serves as an attachment for a muscle or tendon.
What is the Synovial Capsule
the outermost layer of strong fibrous tissue that resembles a sleeve as it surrounds the joint
What is the synovial membrane
Lines the capsule and secretes synovial fluid
What is Synovial Fluid
Flows within the synovial cavity, acts as a lubricant to make the smooth movement of the joint possible
What are ligaments
Bands of fibrous tissue that forms joints by connecting one bone to another bone or by joining a bone to cartilage.
What is the Bursa
A fibrous sac that acts as a cushion too ease movement in areas that are subject to friction, Such as the shoulders, elbows, and knee joints
Axial Skeleton
Protects the major organs of the nervous, respiratory, and circulatory system. Consist of 80 bones of the head and body that are organized into five parts. 1. the bones of the skull, 2. the ossicles: the bones of the middle ear, 3. the hyoid bone, located on the throat between the chin and thyroid, 4. the rib cage, and 5. the vertebral column.
Appendicular Skeleton
Makes body movement possible and protects the organs of digestion, excretion, and reproductive system. Consist of 126 bones that are organized into: the upper extremities (shoulders, arms, forearms, wrists, and hands) and the lower extremities (hips, highs, legs, ankles, and feet)
