Topic ONE - Section ONE - Bones - Movement Flashcards
Identify how many bones are in the human body
206
What are the names of the two divided parts of the skeletal system ?
What are the functions of each ?
Axial Skeleton - Protection
Appendicular Skeleton - Movement
Axial Skeleton consists of :
Cranium
Sternum
Ribs
Vertebral Column
( Cervical , Thoracic , Lumbar , Sacrum , Coccyx )
Appendicular Skeleton consists of :
Clavicle
Scapula
Humerus
Ulna - Upper
Radius
Carpals
Metacarpals
Phalanges
Pelvis ( Pubis , Ischium , Ilium )
Femur
Patella
Fibula
Tibia - Lower
Talus
Tarsals
Metatarsals
Phalanges
Parts of the Vertebrae :
How many vertebra in each :
Cervical - 7
Thoracic - 12
Lumbar - 5
Sacrum - 5
Coccyx - 4
The Functions of Skeletal System :
1 - Shape
2 - Support
3 - Protection
4 - Movement
5 - Blood Cell Production
6 - Mineral Storage
Types of Bones :
Each Function :
Example:
Long Bones - Produce Movement - Femur
Short Bones - Weight Bearing - Talus
Flat Bones - Protection - Ribs
Irregular Bones - Protection - Vertebrae
Sesamoid Bones - Protection - Patella
Joint Classifications :
Examples :
Fibrous ( Fixed / Fused ) - Sacrum/ Coccyx
Cartilaginous ( Slightly Movable ) - Thoracic
Synovial ( Movable ) - Shoulder
Types of Synovial Joints :
Examples :
Hinge - One Plane - Elbow
Ball and Socket - Four Planes - Hips
Condyloid - Three Planes - Wrist
Saddle - Three Planes - Thumb
Pivot - One Plane - Radio-ulna
Gliding - Three Planes - Carpals
Parts of Knee Joints :
Functions :
Cartilage - Shock Absorption - Stabiliser
Ligament - Connect Bones Together
Menisci - Shock Absorption - Stabiliser
Synovial Fluid - Lubricates Joint
Synovial Membrane - Secrete Fluid
Bursae - Friction Reducers
Joint Capsule - Protect Layers Around Joint
Pads Of Fat - Friction Reducers
Joint Movements :
Flexion - Decreasing Angle
Extension - Increasing Angle
Abduction - Away From Midline
Adduction - Toward Midline
Lateral Flexion - Side To Side
- ( Vertebrae )
Medial Rotation - Rotation To Midline
- ( Ball and Socket )
Lateral Rotation - Rotation From Midline
- ( Ball and Socket )
Circumduction - Combination Of :
- Flexion , Extension , Abduction , Abduction
Pronation - Palm Face Down
- ( Radio-ulna )
Supination - Palm Face Up
- ( Radio-ulna )
Dorsiflexion - Toes Toward Tibia
- ( Ankle )
Plantar Flexion - Toes Toward Ground
- ( Ankle )
Horizontal Adduction/Horizontal Extension
- Increasing Angle Parallel To Ground
Horizontal Abduction/Horizontal Flexion
- Decreasing Angle Parallel To Ground
Joint Classifications in the Vertebrae :
Cervical - Synovial
Thoracic - Cartilaginous
Lumbar - Cartilaginous
Sacrum - Fibrous
Coccyx - Fibrous
Short Term Effects - Skeletal System
Positive - Increased Synovial Fluid Production
Negative - High impact activities increase risk of injury
Long Term Effects - Skeletal System
Positive :
Denser Bones
Improved Posture
Improved Weight Management
Negative :
Osteoarthritis
Golfers Elbow
Stress Fractures
Lower Back Pain
Effects of a Cool Down on Skeletal System
Reduced Joint Impact
Reduced Chance of Injury
