Study Notes
Long Bone Structure
- Red bone marrow is crucial for hematopoiesis, the process of blood production.
- The skeletal system serves five functions: support, protection, movement, storage, and hematopoiesis. Functions outside of these are not attributed to the skeletal system.
- The medullary cavity refers to the hollow shaft of a long bone, which houses bone marrow.
- The endosteum is a thin fibrous membrane lining the medullary cavity.
- The periosteum is the strong fibrous membrane covering the surface of the bone, excluding the areas where articular cartilage is present.
- Epiphysis signifies the ends of long bones, which articulate with neighboring bones.
- Trabeculae are needle-like threads of spongy bone that create a supportive network.
- Haversian System is also known as osteons, which provide structural support.
- Lacunae are small spaces in the Haversian system that house bone cells.
- Nutrients and waste products travel between blood vessels and bone cells through canaliculi, small canals facilitating exchange.
- Osteoblasts are responsible for bone formation, while osteoclasts are involved in bone resorption.
- Chondrocytes are the cells found in cartilage and play a role in the formation and maintenance of cartilage tissue.
- The epiphyseal plate is essential for continued bone growth; its presence indicates that growth can still occur.
- Phalanges are the bones located in the fingers and toes.
- Tarsals are the group of bones comprising the ankle and foot.
- The femur is the longest bone in the body, located in the thigh.
- Calcium storage is a critical function of the skeletal system, ensuring homeostasis and physiological balance.
- The articular cartilage covers and cushions the ends of bones, facilitating smooth joint movement.
- The diaphysis is confirmed to be the hollow shaft of long bones.
- Osteoporosis refers to the weakening of bones, significantly affecting women, especially those of childbearing age.
- An improperly healed epiphyseal fracture can lead to limb length discrepancies.
- The tibia and fibula are located in the lower leg, not the lower arm.
- Metacarpals are bones found in the hand, not the foot.
- The pelvis shape distinguishes male and female skeletons, with significant anatomical differences.
- Ligaments are connective tissue bands that connect two bones, providing stability.
- Abduction refers to movement that draws a body part away from the midline of the body.
