Study Notes
Bone Growth and Disorders
- There are three types of ossification: endochondral ossification, which produces most cranial bones and clavicles, and intramembranous ossification, which produces bones at the base of the skull and long bones.
- Bones can grow in width through appositional growth, even after the epiphyseal plate has ossified, as osteocytes lay down bone matrix and osteoclasts expand the medullary cavity.
- Bone remodeling is a continual process involving deposition of new bone and removal of old bone, with different rates of formation and resorption at different life stages.
- Bone fractures go through a series of steps in healing, including the formation of a fracture hematoma, a fibrocartilaginous callus, a bony callus, and bone remodeling.
- Achondroplasia is a condition of abnormal endochondral ossification, leading to short-limbed dwarfism due to a mutation affecting the growth of long bones.
- Acromegaly, caused by excessive growth hormone production, leads to the abnormal growth of flat bones in adulthood, resulting in enlarged head, hands, and feet.
- Rickets is a condition of weak or soft bones in children, often caused by vitamin D deficiency, leading to symptoms such as bowed legs, stunted growth, and bone pain.
- Osteoporosis is a bone disease characterized by bone tissue loss, weakening bones, and increased risk of fractures, particularly when osteoclast activity exceeds osteoblast activity.
- Bone markings include articulating surfaces, elevations, depressions, and openings, each serving specific functions related to joint formation, tendon and ligament attachment, blood vessel and nerve passage, and air pockets within bones.
