Study Notes
Growth and Bone Formation
- A deficiency of growth hormone leads to decreased proliferation of epiphyseal plate cartilage.
- Bones can grow wider through appositional growth, where new matrix is secreted against existing cartilage.
- Hematopoiesis is the formation of blood cells in the red marrow cavities of certain bones.
Bone Anatomy and Projections
- A fracture in the shaft of a bone occurs in the diaphysis.
- Trochanter is classified as a bone projection.
- Essential bone structures include the osteon, which is the structural unit of compact bone.
Bone Development Processes
- Endochondral ossification is a vital process in bone formation.
- Intramembranous ossification occurs during embryonic development.
- Normal bone formation requires adequate intake of calcium, phosphate, and vitamin D.
Cartilage Growth
- Cartilage grows through two mechanisms: appositional and interstitial growth.
- Appositional growth involves the secretion of new matrix on the external face of existing cartilage.
Bone Composition and Function
- Osteoid refers to the organic part of the bone matrix.
- The remarkable hardness of bone arises from the presence of inorganic hydroxyapatites.
- Osteoclasts are responsible for the resorption of bone, making it a dynamic tissue.
Epiphyseal Plate and Hormonal Influence
- In the epiphyseal plate, cartilage grows by pushing the epiphysis away from the diaphysis.
- Growth hormone is the primary stimulus for epiphyseal plate activity during infancy and childhood.
Bone Marrow and Skeleton Function
- Yellow marrow is found in the medullary cavity of long bones in adults.
- The appendicular skeleton primarily supports movement rather than protection of vital organs.
Calcium Regulation
- The thyroid gland produces hormones that decrease blood calcium levels, contrasting with parathyroid hormone which increases it.
- Bone classification is not solely based on weight-bearing or protective functions, debunking a common misconception.
True/False Statements
- Bones are not classified purely by their weight-bearing or protective properties.
- The main role of the appendicular skeleton is not protection and support of vital organs.
