Soc12&13 Skeletal System Flashcards
What are the 5 functions of the skeletal system?
Protection of the Vital Organs
Muscle Attachment
Joints for Movement
Storing Calcium and Phosphorus
Red and White Blood Cell Production
What are all parts of The Vertebrae/Spine
Cervical
Thoracic
Lumbar
Sacrum
Coccyx
What are all the Bones in your Arms?
Humerus
Radius
Ulna
What is the name of the Shoulder Blade?
Scapula
What is the name of the Collar Bone?
Clavicle
What are all the bones in your Ankle/Foot?
Tarsals - Toes
Metatarsals - Toes
Phalanges
What are all your bones in your Hand/Wrist?
Carpals - Cufflinks
Metacarpals - Cufflinks
Phalanges
What are all the bones in your Leg?
Femur
Patella
Tibia
Fibula
What are all the bones in your Torso?
Pelvis
What are the bones in your Skull?
Cranium
What are the 4 types of Bones
Long
Short
Flat
Irregular
What is a Short Bone - With Examples
Short bones are usually associated with weight baring, shock absorption and spreading loads. They play a key role in activities like jogging, playing tennis or dancing.
Tarsals
Carpals
Patella
What is a Long Bone - With Examples
These bones are vital to generate movement, strength and speed. They usually act as levers. When they are pulled by different muscles, they enable the body to move.
Radius
Ulna
Phalanges
What is an Irregular Bone - With Examples
Irregular bones offer protection when playing sport, they tend to form specific functions for example the first and second vertebrae allow the head to turn and nod.
The Vertebrae
What is a Flat Bone - With Examples
Flat bones protect your organs in contact sports and provide attachment for muscles to help movement.
Clavicle
Sternum
Pelvis
What are the 4 types of Joints?
Condyloid
Hinge
Ball and Socket
Pivot
What is a Condyloid Joint?
Similar to ball and socket ,ball rests against end of bone,allows circular motion ,in your wrist and ankle
What is Flexion?
bending movement that decreases the angle between body parts
What is Extension?
straightening movement that increases the angle between body parts
What is Dorsi-Flexion?
bending or flexing the toes up, closer to the shin
What is Plantar-Flexion?
extending or pointing the toes down, away from the shin
What is Abduction?
movement that pulls away from the midline of the body
What is Adduction?
movement that pulls towards the midline of the body
What is Rotation?
movement around a single axis or pivot point
What is Circumduction?
moving in a circular or conical shape
What is a Hinge Joint?
These can be found in the elbow, knee and ankle. Hinge joints are like the hinges on a door, and allow you to move the elbow and knee in only one direction
What is a Ball and Socket Joint?
these types of joint can be found at the shoulder and hip and allow movement in almost every direction. A ball and socket joint is made up of a round end of one bone that fits into a small cup-like area of another bone.
What is a Pivot Joint?
this joint can be found in the neck between the top two vertebrae. It allows only rotational movement such as moving your head from side to side as if you were saying ‘no’.
What is a Tendon?
Tendons are non-elastic fibres that attach muscle to bone and help to move them. Tendons let you apply power and movement. Tendons also grow in strength the more you use them.
What is a Ligament?
Ligaments are elastic fibres taht joins bone to bone usually to hold things and keep them stable.They keep your skeleton supported whilst allowing movements
What is the real name of the skull
Cranium
