Structure And Function Of The Skeleton Flashcards
What bones make up the head/neck region?
Cranium and vertebrae
Which bones are involved in the shoulder joint?
Scapula and humerus
What bones comprise the chest area?
Ribs and sternum
Identify the bones that form the elbow joint.
Humerus, radius and ulna
What bones constitute the hip joint?
Pelvis and femur
Which bones are part of the knee joint?
Femur and tibia
The patella sits in front of the knee joint.
What bones are involved in the ankle joint?
Tibia, fibula and talus
How the skeletal system provides a framework for movement
Allows movement at a joint
Protects our vital organs ( flat bones)
Provides an anchor for our muscles to pull allowing movement to happen
Functions of the skeleton
Support - keeps us upright, hold organs in place
Protection - skeleton protects vital organs
Movement - providing an anchor for our joints to pull agains
Blood cell production - produces red and white blood cell ( in bone marrow)
Mineral storage - store shi like calcium in bones
Structure of synovial joint and its function
synovial membrane
• synovial fluid - lubricates the joint
• joint capsule
• bursae - fluid filled bag that reduces friction
• cartilage -provides smooth friction free surface
• ligaments - attaches bone to bone
Plantar flexion and dorsiflexion
P - Point ( movement down)
D - draw ( movement up)
Muscles at elbow joint
Humerus radius ulna
Muscles at head and neck joint
Veterbrae and cranium
Muscles at shoulder joint
Scapula humerus
Hip joint
Femur and pelvis
Knee joint
Femur patella and tibia
Ankle joint
Tibia fibula and talus
How muscles group work
Isotonic - muscle changes length
2 types
Concentric - muscle shortens and contracts (bicep curls)
Eccentric- muscle lengthens and contracts ( lowering barbell in a bench press)
Isometric - muscle remains the same length as it contracts ( handstand)
