Unit 3 Kinesiology Flashcards
Characteristics of Synovial Joint
Movement in multiple planes
Types of Joints
Pivot, Saddle, Gliding Joint, Hinge, Ellipsoid, Ball & Socket
Pivot Joint
(Uniaxial)
in the neck
Allows rotation in one plane.
A rounded point of one bone fits into a groove of another.
Saddle Joint
(Bi-axial)
thumb
The projection of one bone fits into the oval-shaped depression of another bone.
Movement in two planes.
Gliding Joint
(Non-Axial)
wrist and ankle
Connects flat or slightly curved bone surfaces allow the bones to glide past one another in any direction along the plane of the joint, up and down, left-right, and diagonally.
Hinge Joint
(Uniaxial)
elbow & knee
Convex portion of one bone fitting into a concave portion of another.
Movement in one plane.
Ellipsoid Joint
(Bi-Axial)
wrist
The projection of one bone fits into the oval-shaped depression of another bone.
Movement in 2 planes
Ball-and-Socket
(Tri-axial)
Hip
Most movable; forward, backward, and circular.
The ball of one bone fits into the socket of another.
Movement in 3 axes.
Uniaxial Joint
Only allows movement in one plain. ex: Pivot & Hinge Joint.
Bi-axial Joint
Allows movement in 2 planes. Ex: Saddle & Ellipsoid Joint
Non-Axial Joint
Very little movement, side to side, back and forth, left and right.
Gliding Joint
Tri-axial Joint
Allows movement in several directions
Olecranon
Boney part elbow
Acetabulum
Socket of hip bone
Femoral Condyle
The two bumps on the distal end of the femur
Bursa
small fluid-filled sac
Difference between a Sprain and a Strain
sprain tears ligaments, strain are muscle
Patellafemoral Sydrom vs Osdgood
P=women O=men
Diarthrotic
allows lots of movement, like a synovial joint
Synarthrotic
does not move (skull bones)
Amphiarthrotic joints
limited movement like vertabrae
Hayline cartilage
Found at ends of bones
