Study Notes
Bone Tissue and Functions
- Osteoclasts are the cells responsible for breaking down bone tissue.
- Red bone marrow primarily functions in the production of blood cells.
- The femur is the longest and strongest bone in the human body.
- The skull protects the brain within the skeletal system.
Joints and Growth
- The ball-and-socket joint in the shoulder allows for a wide range of motion.
- The periosteum is the tough, fibrous membrane covering the outer surface of bones, excluding joints.
- Bone growth occurs in the epiphyseal plate of long bones.
Cartilage and Hormones
- Articular cartilage is located at the ends of long bones and helps reduce friction in joints.
- Calcitonin is the hormone released when blood calcium levels are too high.
Fractures and Skeleton Structure
- A comminuted fracture is characterized by a bone breaking into multiple pieces.
- The axial skeleton includes the skull, vertebral column, and rib cage.
Vitamins and Bone Structure
- Vitamin D is essential for calcium absorption in the digestive system.
- Compact bone has a dense, solid structure, as opposed to spongy bone.
Marrow and Deficiencies
- The medullary cavity of long bones contains yellow marrow.
- Rickets is a condition caused by vitamin D deficiency, leading to soft and weakened bones in children.
Joint Types and Vertebral Function
- Fibrous joints are present between the bones of the skull.
- The vertebral column supports the body and protects the spinal cord.
Jaw Bone and Axial Skeleton Exemptions
- The mandible forms the lower jaw and is the only movable bone of the skull.
- The femur is not part of the axial skeleton, which includes bones such as the sternum, ribs, and vertebrae.
Diseases Related to Bones
- Rheumatoid arthritis is a disease where the immune system attacks the joints, causing inflammation and pain.
