Question Answer
Articulations Functional joints between bones. they bind parts of the skeletal system and make possible bone growth.
Fibrous Joints Dense connective tissues composd mainly of dense connective tissues.
Syndesmosis (fibrous) Bones bound by long fibers of connective tissue that form an interosseous ligament.
Suture (fibrous) between flat bones of the skull.
Gomphosis (fibrous) joint formed by union of a cone-shaped bony process in a bony socket.
Cartilaginous Joints Joints whose bones are connected by hyaline or fibrocartilage.
Synchondrosis (cartilaginous) Band of Hyaline cartilage unite the bones.
Synovial Joints Comprise most joints of the skeletal system. they allow for free movement are are diathrotic.
Articular Carilage (Synovial) Resists wear and minimizes friction when it is compressed as the joint moves.
Joint Capsule (synovial) Has two distinct layers that hold together the bones of the synovial joint.
Ligaments Bundles of strong, tough collagenous fibers.
Synovial Membrane Covers all surfaces within joint capsule, except areas covered by articular cartilage.
Menisci Disks of fibrocartilage divided by synovial joints.
Bursae Fluid filled sacs associated with certain synovial joints.
Ball-and-socket Joint Boen with a globular or slightly egg-shaped head that articualtes with the cup-shaped cavity of another bone.
Condyloid Joint Ovoid condyle of one bone fits into the elliptical cavity of another bone.
Gliding Joints nearly flat or slightly curved. allow sliding or back and fourth motion and twisting movements.
Hinge Joint convex surface of one bone fits into the concave surface of another.
Pivot Joint Cylindrical surface of one bone rotates Within a ring formed of bone and fibrous tissue of ligament.
Saddle Joint Forms between bones whose articulating surfaces have both concave and conves regions.
Flexion Bending parts at a joint so angle between them decreases and parts come closer together.
Extension Straightens joint so angle bewteen increases and they move farther apart.
Hyperextension Excess extension of the parts at a joint, beyond anatomical position.
Dorsiflexion Bending foot at ankle toward shin.
Plantar Flexion Bending foot at ankle otawrd sole.
Abduction Moving part away from the midline.
Adduction Moving a part toward midline.
Rotation Moving part around an axis.
Circumduction Moving a part so its end follows a circular path
Supination Turning hand so palm is upward or facing facing anteriorly.
Pronation Turning hand so the palm is downward or facing posteriorly.
Eversion Turning foot so the sole faces laterally.
Inversion Turning foot so sole faces medially.
protraction Moving a part forward.
Retraction Moving a part backward.
Elevation Raising a part.
Depression Lowering a part.
