Flashcards
Muscle Attachment to Bones
Muscle Attachment to Bones
Bones provide a framework for muscle attachment, allowing movement.
Bone Marrow Functions
Bone Marrow Functions
Bone marrow produces red blood cells (RBCs) for oxygen transport. White blood cells (WBCs) provide immunity.

Study Notes
Bone Structure and Function
- Bone cap restoration may not be possible through surgery if a serious deformity or inability develops
- Microscopic canals are visible in a horizontal cross-section, serving as pathways for nerves and blood vessels, called Haversian canals
- The outer part of bone is typically very hard
- Long bones such as the femurs, radius, ulna, humerus, tibia, and fibula, have a hollow shaft filled with bone marrow
Bone Marrow and Composition
- The hollow central canal within long or flat bones contains bone marrow
- Bone marrow is the site of red blood cell (RBC) production
- RBC production is directly proportional to the bone marrow's health; damage can affect RBC production and lead to anemia
- Certain chemicals, like heavy metals and benzol, can injure bone marrow, potentially resulting in bone tumors
- Bones are composed of 2/3 various sizes and shapes, which generally perform functions
Bone Functions
- Bones provide support for surface attachment to internal organs
- Bones gives a definite shape to the body
- Bones protect soft, vital organs, such as the skull protecting the brain, and the thoracic cage protecting the heart and lungs
Bone Marrow Components and Joints
- Bone marrow produces red blood cells (RBCs) and white blood cells (WBCs)
- RBCs are essential for oxygen transport, which is used for energy production
- WBCs contribute to the body's disease resistance and immune capabilities
- Joints are formed by the bones, which allow movements
Muscles and Bones
- Muscles attach to the bones
- Muscle limbs construction allows for relaxation and movement
