Component 1 (joints, Movement, Ligament, And Tendons): Soc 13 Flashcards
What are the 4 types of bones?
-Long bones
-Short bones
-Irregular
-Flat bones
What are the long bones?
They are longer than they are wide to generate movement (leavers)/strength
What are the short bones?
They are same size in length, width and thickness. They are the carpals and tarsals in the foot
What is the Irregular bone
They are to protect/generate movement
What are the flat bones
To protect the vital organs/muscle attachment
What is the pivot joint?
Allow the bones to rotate. They are one bone shaped like cylinders inside another bone or ligament
Example:
-Neck
What is the hinge joint?
Moves back and forwards the three joints:
-Knee- Can be bent (flexion) and straightend (extension)
-Elbow- Joint between the humerous and ulna
-Ankle
What is the ball and socket joint?
Rounded head long bone (the ball) fits into a cup-shaped hole (the socket)
Example:
-Hip
-Shoulder
What is the condyloid joint?
Similar to a ball and socket. The joint rests agaisnt the end of the bone allows circular motion
What is rotation?
Turning around the axis arm and the limb remain in place but the palm would face in different as the arm rotats from a supine
What is Felxion?
Bending movement that increases the angle between body parts
Joints that provide it
-shoulder
-hip
-elbow
Example in sport (flexion)
Someone working out in the gym doing bicep curl
What is extension?
Straigtening movement that increases the angle between body parts
Joints that provide it
Shoulder
Hip
