Joints Test
Enter the letter for the matching Answer
| A. Immovable joint formed when the gap between two bones ossifies and become one.
Example: Infants are born w/ a RT and LT frontal bone-which fuses together to form one frontal bone.B. Supination:Movement of palm to anterior(upward) position
Pronation: Movement of palm to posterior(downward) position.
Position: Supinated position
Example:proximal and distal radioulnar jointC. Fibers are longer and the attached bones are more movable.
Example: Between the tibia/fibula and ulna/radiusD. Tough dense regular collagenous connective tissue that attaches bone to bone.E. 1. Articular Disc: In the sternoclavicular joint-the the articular disc covers the entire joint capsule.
2. Meniscus: in the knee- 2 cartilage pads extend inward from LT to RT- but do NOT entirely cross the joint.F.
Similar to a ball and socket, but movement is more restricted. Allows two way-biaxial movement.
Example: Metacarpophalangeal (knuckles)G. When bones are connected by 'Hyaline Cartilage'(articular cartilage)
Example:*The epiphyseal plates of the long bones seen in children-
*Attachment of rib to sternum by hyaline coastal cartilage.
H. Protraction: Closer to vertebral column
Retraction: Away from vertebral column
Position: Frontal planeI. Inversion: Turning foot inward
Eversion: Turning foot outward
Position: Frontal Plane
Example: Subtalar jointJ. Bones are joined by fibrous tissues. No joint cavity is present. The amount of movement depends on the on the length of the fibers uniting the bones.K. Bones formed by 'Fibrocartilage'
Example: Pubic Symphysis and the intervertebral joints.
L. Abduction: Away from midline
Adduction: Towards midline
Position: Frontal Plane
Example: Fanning of fingers and bringing back together
M. Upward Rotation: Tips up
Downward Rotation: Tips down
Position: Frontal Plane
Example: Scapulothoracic
N. Dorsiflexion: Toes flexed towards knees
Plantarflexion: Toes pointed down
Position: Sagittal Plane
Example: Talocrural JointO. Articular biaxial surface is shaped like a saddle. Example: carpalmetacarpal of thumb(CMC of thumb)P. (Monoaxial joint) An example of this type of joint is the articulation between the atlas and axis (C1 and C2), which allows the head to rotate from side to side (in the "no" motion). C1 & C2 rotationQ. Lateral Rotation: External Rotation
Medial Rotation: Internal Rotation
Position: Transverse Plane
Example: Hip and Glenohumeral JointR. Elevation: Arms up-pushes scapula up
Depression: Arms Down
Position: Frontal Plane
Example: Scapulothoracic Joint
S. Sutures, Gomphoses, and SyndesmosesT. Flexion: Bending
Extension: Straightening
Anatomical Plane: Sagittal
Example: arm, knee, humeral joint, hip |
