Study Notes

Bone Structure and Function

  • Osteoclasts: Cells that break down bone for remodeling.
  • Short Bones: Examples include carpals and metacarpals; these are a type of bone.
  • Connective Tissue: Holds bones together, enabling movement and stability. This is a type of tissue.
  • Osteoblasts: Primary building blocks, providing structure and support. Bone-building cells depositing minerals and forming tissue.

Bone Development and Growth

  • Marrow Function: Crucial for blood cell production and energy storage.
  • Secondary Ossification: Osteoblasts replace cartilage with bone from the center outward.
  • Cartilage: Flexible tissue cushioning joints and providing structure.
  • Mature Bone: Reaches adult form but continues to remodel.
  • Primary Ossification: Bone formation continues at ends, forming growth plates.

Bone Types

  • Short Bones: Example includes vertebrae.
  • Irregular Bones: Not easily categorized into the other main types. These are unique shapes, such as vertebrae.
  • Long Bones: Example includes femur and humerus.
  • Flat Bones: Example includes the scapula. These are generally thin and flat.

Bone Tissue

  • Yellow Marrow: Produces red blood cells in children; stores fat in long bone cavities.
  • Compact Bone: Outer layer providing strength and protection; dense bone.
  • Spongy Bone: Bone formation that continues at ends, forming growth plates; porous bone.
  • Cartilage Model: Embryonic bones beginning as cartilage models.

Bone Remodeling and Repair

  • Bone Density: May decrease with age.
  • Bone Growth and Repair: Bones grow, repair, and adapt to stress; dynamic structure.
  • Bone Healing: Bones heal themselves through regeneration and are alive and constantly changing; self-repair.
  • Bone Strength: Strengthens in response to physical activity; dynamic structure. This adaptability.
  • Intramembranous Ossification: One method of bone development, important in bone remodeling.

Bone Classifications

  • Axial Skeleton: Comprises skull, spine, ribcage, and limbs attached to it. It is the central axis of the body.
  • Appendicular Skeleton: Includes limbs; attached to the axial skeleton.
  • Primary Ossification: Bone formation continues at ends, forming growth plates.
  • Secondary Ossification: Osteoblasts replace cartilage with bone from the center outward. This is a type of bone development.
