Study Notes
The Skeletal System: An Overview
The skeletal system is the body's structural framework, responsible for supporting the body and protecting its vital organs. It is composed of 206 bones, which act together as a single unit. The skeletal system is part of the musculoskeletal system, which also includes muscles, tendons, cartilage, ligaments, and other soft tissues.
Skull
The skull is the bone structure that forms the head and contains the brain, face, and ear cavities. It is composed of 22 bones, with 14 of these bones forming the facial bones. The skull is divided into two basic parts: the cranial cavity and the facial cavity. The cranial cavity holds the brain, and the facial cavity holds the eyes, ears, nose, and mouth.
Femur
The femur, also known as the thighbone, is the longest and strongest bone in the human body. It is a long bone, which is the type of bone that is cylindrical in shape. The femur is located in the thigh, connecting the hip to the knee joint. It is the weight-bearing bone of the leg and is the lever arm for the muscles of the thigh.
Vertebrae
The spine, or backbone, is a column of bones, muscles, and other tissues in the vertebral column. It is made up of 33 vertebrae, including 8 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 fused vertebrae (sacrum), and 4 fused vertebrae (coccyx). The spine provides support and protection for the spinal cord, which is the information highway of the body.
Ribs
The rib cage is the cage formed by the thoracic cage bones, which is the cage of the chest that is formed by the ribs. The rib cage protects and supports the heart and lungs. There are 24 ribs in total, but only 12 are true ribs, and the rest are false ribs and floating ribs.
Pelvis
The pelvis is a large, strong bone that forms the lower part of the trunk of the body. It is made up of three bones: the ilium, ischium, and pubis. The pelvis serves as a ring for the attachment of the legs and the attachment of most of the muscles of the trunk.
In conclusion, the skeletal system is a complex network of bones, muscles, and other tissues that work together to support the body and protect its vital organs. Each part of the skeletal system, including the skull, femur, vertebrae, ribs, and pelvis, plays a critical role in maintaining the body's structure and function.
