Study Notes
Anatomy & Physiology - Bone
- The skeletal system includes bones, joints, ligaments, and cartilage.
- The primary functions of the skeletal system are support, protection, and movement. It also stores fat and minerals and forms blood cells.
- Bones protect soft tissues and organs, such as the skull that protects the brain, ribs protect the thoracic organs (lungs, heart, and kidneys), vertebrae protect the spinal cord, and the pelvis protects the urinary bladder, reproductive organs, and digestive organs.
- Compact bone is made of haversian systems.
- Spongy bone is located in the epiphysis and has a lattice-like structure.
- Epiphyseal lines are made of solid compact bone.
- Epiphyseal plates are made of hyaline cartilage (growth plates).
- The epiphyseal plates change to epiphyseal lines between 18-20 years old in males and ages 16-18 in females.
- Articulating cartilage is located on the ends of all bones that articulate (move). It is made of hyaline cartilage. This cartilage cushions and allows for movement.
- The epiphysis are the ends of long bones.
- The diaphysis is the shaft of long bones, typically yellow marrow.
- The epiphyseal line is the site of ossification or the line between the epiphysis and diaphysis.
- The site of red bone marrow in long bones are the epiphysis.
- The site of yellow bone marrow in long bones is the diaphysis
- There are four types of bone shapes in the human body: long, short, flat, and irregular. Examples: long (femur, humerus), short (patella, tarsals, carpals), flat (sternum, ribs, pelvis, skull), and irregular (vertebrae, hyoid, ethmoid).
- The structure for the process of ossification for bone includes the following: (a) Bone collar forms around the hyaline cartilage model, (b) cartilage is calcified in the center of the model, and (c) the periosteal bud invades the internal cavities and spongy bone forms at the primary ossification center. (d) The diaphysis elongates, the medullary cavity forms, and the secondary ossification centers appear in the epiphyses. (e) The epiphyses ossify, with hyaline cartilage remaining only at the epiphyseal plates and articulation cartilage.
