Anatomy Flashcards
What are bone cell compromised of
Osteoblasts which form bone by secreting collagen
Osteoclasts, which dissolve bone mineral
Leverage
The length of the bone determines how much leverage you have
Weight bearing
Bones at the pelvis and legs are strong and thick so they can take weight of Skelton
Protection
Vital organs are protected from damage due to bone
What are the functions of a long bone
Source of red cell production, Enable large movement and acts as a lever
Types of bone
Long, short, flat, Irregular, sesamoid
What is the function of a short bone
Increase stability, weight bearing and absorbs shock
What is the function of articulate cartilage
Reduce friction and absorb shock
What is the function of ligaments
Connects bone to bone
What is synovial membrane
A thin barrier that lines the inside of some joints
What is the function of a synovial membrane
Secretes synovial fluid
What is the function of bursa
Found in most major synovial joint which reduces friction
Flexion
Flexion means reducing the angle of the bones forming the joint
What is abduction
What is adduction
Away from the midline
Towards the midline
What is lateral Flexion of the spine
Spine moves from side to side. Cervical vertebrae such as moving neck sideways. Thoracic and lumber vertebrae such as moving the upper body
