Skeletal

Function

Provide structure and framework
Provides protection and strength
Allows for movement by attaching to skeletal muscle via tendons which enables muscles to move joints
Storage site for minerals
- Calcium & Phosphorus
Production of Blood Cells in the Red Bone Marrow
Energy Storage
- Lipids stored in yellow bone marrow

Fibrous - Immovable

Cartilaginous - Slightly Movable

Synovial - Freely Movable

Articular Cartilage
- Protects ends of bones (cushion), reduces friction
Joint Capsule
- Fibrous Membrane - encloses the joint cavity
Joint Cavity – Joint Space
- Synovial Membrane – produces synovial fluid
- Synovial Fluid – lubricates the joint, protects cartilage

Example of a Synovial Joint

Example of Ligaments in the Human Knee

Fibrous Connective Tissue
Connect Muscle to Bone
Sheath
- Surrounds the tendon (synovial membrane)
- Produces synovial fluid
- Allows for movement

Tough connective tissue (chondrocytes)

Hyaline – most common, end of long bones, connects ribs to sternum, trachea (rings), embryonic skeletons, growth plates

Elastic – epiglottis, pinnae

Fibrocartilage – often w/ hyaline cartilage, intervertebral space, knee, pelvic girdle

Axial skeleton: central axis of body = skull, vertebral column, ribs and sternum

Appendicular skeleton: Pectoral and pelvic girdles, wings and legs

Example of an Animal with the Appendicular and Axial Skeleton Labeled. Similar with chickens.
