Study Notes
Bone Structure and Composition
- The bone marrow, which is located within the medullary cavity of long bones, contains blood stem cells that can differentiate into red blood cells (RBC), white blood cells (WBC), or platelets.
Tissue Layers
- The periosteum, a fibrous connective tissue, surrounds bones and provides a site for muscle attachment, nerve and blood vessel passage, and bone growth.
Skeletal Systems
- The hydrostatic skeleton, supported by the pressure of body fluids, is found in animals such as worms and starfish.
Vertebrates
- Vertebrates are a group of animals characterized by the presence of a vertebral column (backbone).
Skeletal Types
- The endoskeleton, composed of bones and cartilages, is found in vertebrates.
- The exoskeleton, found in arthropods and some molluscs, is a hard outer covering that provides support and protection.
Tissue Definition
- Cartilage is a flexible, yet strong, connective tissue found in various body parts, including the ears, nose, and joints.
