Study Notes

Bone Structure and Tissue

  • Bone is comprised of osseous tissue.
  • The shaft of a bone is referred to as the diaphysis.
  • The ends of a bone are called the epiphysis.
  • Spongy bone is also known as cancellous or trabecular bone.
  • Compact bone is alternatively referred to as dense or cortical bone.

Bone Regions and Coverings

  • The metaphysis is the region between the diaphysis and epiphysis.
  • Bones are covered on the outside by the periosteum, which is secured to the bone by perforating fibers.
  • The inside of the bone is lined by the endosteum.

Bone Cells and Functional Units

  • Osteoprogenitor cells, located in the periosteal and endosteal layers, are stem cells that develop into osteoblasts.
  • Osteocytes are mature bone cells that reside in lacunae.
  • The basic functional unit of compact bone is called osteons.
  • Lacunae are interconnected by canaliculi.
  • Spongy bone contains trabeculae, which are the network of spicules.

Bone Formation and Resorption

  • Osteoclasts are cells involved in dissolving the bony matrix, releasing calcium and phosphate ions into the bloodstream.
  • Osteocytes are responsible for synthesizing or creating the bony matrix.
  • Endochondral ossification begins with the formation of a hyaline cartilage model, which is eventually replaced by bone.

Bone Growth and Health

  • Appositional growth increases bone diameter.
  • Interstitial growth refers to longitudinal bone growth, occurring at the epiphyseal plate.
  • Osteopenia is the normal aging process marked by loss of bone density.
  • Osteoporosis is a pathological condition characterized by significant bone density loss over time.

Joint Movements

  • Abduction: Raising the arm laterally.
  • Adduction: Returning the arm to the body.
  • Flexion: Bending the elbow.
  • Extension: Returning the bent elbow to anatomical position.
  • Hyperextension: Bending the neck backward beyond its normal range.
  • Circumduction: Movement combining all directions into a circular motion.

Ranges of Motion for Movements

  • Flexion: Decreases angle between bones.
  • Extension: Increases angle between bones.
  • Lateral flexion: Trunk moves laterally.
  • Rotation movements:
    • Lateral rotation: Turns bone anterior surface laterally.
    • Medial rotation: Turns bone anterior surface medially.
  • Pronation: Medial rotation of forearm, palm facing down.
  • Supination: Lateral rotation of forearm, palm facing up.
  • Elevation/Depression: Movement of body part superiorly/inferiorly.
  • Dorsiflexion and Plantar flexion: Movements of the ankle joint.

Joint Types

  • Synarthrosis: Immovable joint (e.g., cartilaginous joints).
  • Amphiarthrosis: Slightly movable joint (e.g., fibrous joints).
  • Diarthrosis: Freely movable joint (e.g., synovial joints).

Bone Marrow and Energy Storage

  • Yellow bone marrow is the energy reserve area storing lipids in adult skeletal bones.
  • Bone marrow is a hematopoietic region, responsible for producing blood cells.

Osteoprogenitor Cells and Lamellae

  • Osteoprogenitor cells differentiate to form osteoblasts and play a crucial role in bone repair.
  • Concentric lamellae are found within osteons, while interstitial lamellae occupy spaces between osteons in compact bone.
