Joint stuff

Syndesmosis, Suture and Gomphosis are ______ joints. Fibrous
Made out of many collagenous fibers, held together by dense connective tissue. They lie between bones that closely contact one another. Fibrous
bones bound by long fibers of connective tissue that forms an interosseous ligament, allowing slight movement. At the distal ends of the tibia and fibula. Syndesmosis
Between flat bones of the skull, where broad margins of adjacent bones grow together and unite by a thin layer of dense connective tissue. Immovable (synarthrotic joint). Suture
A joint formed by the union of a cone-shaped bony process in a bony socket. Ex. the root of a tooth fastened to a jawbone. No movement (synarthrotic joint). Gomphosis
Synchondrosis and Symphysis are _____ joints Cartilaginous
Hyaline cartilage or fibrocartilage connect the bones of Cartilaginous Joints
Bands of hyaline cartilage unite the bones. Many of these joints are temporary structures that disappear during growth. Ex. immature long bone connexts epiphysis to a diaphysis, before the age of 25, movement no longer occurs at this joint. Synchondrosis
The articular surfaces of the bones are covered by a thin layer of hyaline cartilage, attached to a pad of springy fibrocartilage. limited amount of movement. Ex. in the pelvis, Pelvic bones shift when giving birth and between vertebrae to absorb shock Symphysis
Ball-and-Socket, Condyloid, Gliding, Hinge, Pivot and Saddle are types of ______ joints Synovial (diarthrotic)
Articulating bones surrounded by a joint capsule of ligaments and synovial membranes; ends of articulating bones covered by hyaline cartilage adn separated by synovial fluid Synovial Joint
Ball-shaped head of one bone articulates with cup-shaped socket of another. Movements in all planes. Ex. Shoulder, hip Ball-and-Socket
Oval-shaped condyle of one bone articulates with elliptical cavity of another. varitey of movements in different planes, but no rotation. Ex. Joints between metacarpals and phalanges. Condyloid
Articulating surfaces are nearly flat or slightly curved. Sliding or twisting. Ex. Joints between various bones of wrist and ankle. Gliding
Convex surface of one bone articulates wiht concave surface of another. Flexion and extension. Ex. Elbow and joints of phalanges Hinge
Cylindrical surface of one bone articulates with ring of bone and fibrous tissue. Rotation. Ex. Jiont between proximal ends of radius and ulna. Pivot
Articulating surfaces have both concave and convex regions, surface of one bone fits the completmentary surface of another. Variety of movements, mainly two planes. Ex. Joint between carpal and metacarpal of thumb. Saddle
Bending parts at a joint so that the angle between them decreases and the parts come closer together. (bending the lower limb at the knee) Flexion
Straightening parts at a joint os that the angle between them increases and the parts move farther apart (straightening the lower limb at the knee). Extension
Excess extension of the parts at a joint, beyond the anatomical poisition (bending the head back beyond the upright position). hyperextension
Bending the foot at the ankel toward the shin (bending the foot upward). Dorsiflexion
Bending the foot at the ankle toward the sole (bending the foot downward). Plantar Flexion
Moving a part away from the midline (lifting the upper limb horizontally to form a right angle with the side of the body). Abduction
Moving a part toward the midline (returning the upper limb from the horizontal poisiton to the side of the body) Adduction
Moving a part around an axis (twistin the head form side to side) Medial rotation involves movement toward the midline, whereas lateral rotation involves movement in the opposite direction rotation
moving a part so that its end follows a cicular path (moving the finger in a cicular motion wihtout moving the hand). Circumduction
turning the hand so the palm is upward of facing anteriorly (in anatomical position) supination
Turning the hand so the palm is downward or facing posteriorly (in anatomical poisition) pronation
Turning the foot so the sole faces laterally eversion
Turning the foot so the sole faces medially Inversion
Moving a part forward (thrusting the chin forward). Protraction
Moving a part backward (pulling the chin backword). Retraction
Raising a part (shrugging shoulders) Elevation
Lowering a part (dropping the shoulders). Depression
