Skeletal System



Articulations (Joints)

Describe the structural/functional classifications of joints: fibrous/immovable joints; cartilaginous/slightly movable joints; synovial/freely movable joints. Describe the basic structure of synovial joints including: 1. synovial membrane and capsule. 2. synovial fluid. 3. articular cartilage. 4. bursae. Distinguish between the functions of tendons and ligaments. Shoulder joint: 1. identify the bones and structures comprising the shoulder joint. [...]

Bone Growth

There are three kinds of bone growth: endochondral ossification (for long bone growth); intramembranous ossification (for flat, irregular bone growth); and remodeling (role of osteoblasts and osteoclasts). Endochondral Ossification Occurring in fetal development, this is the development of a cartilage model into a skeletal system. Intramembranous Ossification Occurring in fetal development, this is the development [...]

Bone Tissue & Structure

Below are three increasingly-magnified photos of a histology slide featuring human bone. Notice the structure of the bone. B. Define the following anatomical terms: 1. diaphysis. 2. epiphysis. 3. epiphyseal (growth) plate. 4. articular cartilage. 5. periosteum. 6. compact bone tissue & distribution. 7. spongy bone tissue & distribution. C. Identify the functions the cells [...]

Ossification

Intremembraneous ossification involves the replacement of sheet-like connective tissue membranes with bony tissue. Bones formed in this manner are called intramembraneous bones. They include certain flat bones of the skull and some of the irregular bones. The future bones are first formed as connective tissue membranes. Osteoblasts migrate to the membranes and deposit bony matrix [...]
