Question | Answer |
What are Fibrous Joints? | Articulating bones fastened together by thin layer of dense connective tissue containing many collagenous fibers. |
What are the three different types of Fibrous Joints? | Syndesmosis, Suture, and Gomphosis. |
What is a Syndesmosis (Fibrous) Joint? | Bones bound by interosseous ligament. |
What is a Suture (FIbrous) Joint? | Flat bones united by sutural ligament. |
What is a Gomphosis (Fibrous) Joint? | Cone-shaped process fastened in tbony socket by periodontal ligament. |
What is a Cartilaginous Joint? | Articulating bones connected by hyaline cartilage or fibrocartilage. |
What are the Two different types of Cartilaginous Joints? | Synchondrosis and Symphysis |
What is a Synchondrosis (Cartilaginous) Joint? | Bones united by bands of hyaline cartilage. |
What is a Symphysis (CArtilaginous) Joint? | Articular surfaces separated by thin layers of hyaline cartialge attached to band of fibrocartilage. |
What is a Synovial Joint? | Articulating bones surrounded by a joint capsule of ligaments and synovial membranes; ends of articulating boones covered by hyaline cartilage and separated by synovial fluid. |
What are the Six different types of Synovial Joints? | Ball-and-Socket, Condyloid, Gliding, Hinge, Pivot, and Saddle. |
What is a Ball-and-Socket (Synovial) Joint? | Ball-shaped head of one bone articulates with cup-shaped socket of another. |
What is a Condyloid (Synvoial) Joint? | Oval-shaped condyle of one bone articualtes with eliptical cavity of another. |
What is a Gliding (Synovial) Joint? | Articulating surfaces are nearly flat or slightly curved. |
What is a Hinge (Synovial) Joint? | Convex surface of one bone articulates with concave surface of another. |
What is a Pivot(Synovial) Joint? | Cylindical surface of one bone articulates with ring of bone and fibrous tissue. |
What is a Saddle (Synovial) Joint? | Articulating surfaces have both concave and convex regions; surface of one bone fits the complementary surface of another. |
What are the 17 Types of Joint Movements? | Flexion, Entension, HyperExtension, DorsiFlexion, Plantar Flexion, Abduction, Adduction, Rotation, Circumduction, Supination, Pronation, Eversion, Inversion, Protraction, Retraction, Elevation, and Depression. |
What is Flexion? | Bending parts at a joint so that the angle between them decreases and the parts come closer together. |
What is Extension? | Straightening parts at a joint so that the angle between them increase and the parts move farther apart. |
What is HyperExtension? | Excess extension of the parts at a joint, beyond the anatomical position. |
What is DorsiFlexion? | Bending the foot at the ankle toward the shin. |
What is Plantar Flexion? | Bending the foot at the ankle toward the sole. |
What is Abduction? | Moving a part away from the midline. |
What is Adduction? | Moving a part toward the midline. |
What is Rotation? | Moving a part around an axis. |
What is Circumduction? | Moving a part so that its end follows a circular path. |
What is Supination? | Turning the hand so the palm is upward or facing anteriorly. |
What is Pronation? | Turning the head so the palm is downward or facing posteriorly. |
What is Eversion? | Turning the foot so the sole faces latterally. |
What is Inversion? | Turning the foot so the sole faces medially. |
What is Protraction? | Moving a part forward. |
What is Retraction? | Moving a part backward. |
What is Elevation? | Raising a part. |
What is Depression? | Lowering a part. |
