Another name for synostosis (SIN-oss-TOE-sis) is:
and give an example
a boney joint
Example: epiphysial plate clousure
another name for synarthrosis (SIN- ar-THRO-sis) or synarthrodial joint is:
And give an example:
a fibrous joint
Example: the skull
the point at which adjacetn bones are bound by collage fibers that emerge from one bone, cross space between them and penetrate into another is called:
synarthrosis or synarthrodial joint
an immoveable joint formed when the gap between two bones ossifies and they become a single bone is called:
List the three types of subtypes of synarthrodial joints/synarthorsis:
Sutures - serrate, lap, plane
gomphosis (gom-FOE-sis) - tooth to socket
syndesmosis (SIN-dez-MO-sis) - long callagenous fibers (radius/ulna)
Another name for a ampiarthrosis (AM-fee-ar-THRO-sis) or ampiathrodial joint is:
Give an Example:
List the two subtypes of ampiarthrodial joints/ampiarthorsis:
synchondrosis (SIN-con-DRO-sis) - bones bound by hyaline cartilage: EX - joint b/w epiphysis/diaphysis in long bone child + attachmnet 1st rib to sternum
symphysis ( SIM-fih-sis) - bones joined by fibrocartilage : EX- pubic symphysis + 2 vertebraes united by intervertebral disc
a layer of hyaline cartilage in synovial joints is called:
the articular cartilage are separted by a narrow space called the ________, containing a slippery lubericant called synovial fluid
joint (articular) cavity
the fluid wihd is rich in alumin and hyaluronic aicd, which gives it a viscous, slippery texture similar to raw egg whites is called:
a connective tissue ______ encloses the cavity and retains the fluid.
another name for diarthrosis (DY-ar-THRO-sis) or diarthrodial joint is:
Give an example
a tissue that attaches one bone to another is called a:
a strip or sheet of tough collagenous connective tissue that attaches muscle to a bone is called:
a fibrous sac filled with synovial fluid that cushions muscles and helps tendons slide more easily over the joints is called:
an elongated cylindriacl bursae wrapped around a tendon, that enables tendons to move back and forth more freely in tight spaces such as the wrist and ankle, is called:
the thendon sheath
two cartilages that extend inward from the left and right but do not entirely cross at the joint is called a _______, in which absorbs shock/pressure, guide bones across each other, and stabilize the joint.
the degrees through which a joint can move is called:
range of motion
what determins range of motion?
1. structure of the articular surfaces of the bones: EX- elbow cant go past 180 b/c the olecranon of ulna swings into olecranon fossa of humerus
2. Strength and tautness: cruciate ligaments prevent hyperextension
3. Actions of muscles/tendons: pairs of muscles oppose each other, muscle tone (resting muscle, stabilize joint)
the movement of a body part in the frontal plane away from the midline of the body is called:
abduction: EX - moving the feet apart to stand spread-legged
the movement in teh frontal plane back towards the midline is called:
the moveement that raises a body part vertically in the frontal plane is called:
Elevation: Ex- to lift a suitcase off the floor, you elevate the scapula
the movment in which a body part is lowered in the frontal plane is called:
depression: EX - to set the suitcase donw again, you depress the scapula
the anterior movement of a body part in teh transverse (horizontal) plane is called:
protraction: EX - shoulders protraction when you reach forward to open a door
the posterior movement in the transvers plane is called:
retraction: EX - pulling the shoulders back to stand in a military position
the movement in which one end of the appendage remains fairly stationary while the other end makes a circular motion is called:
a movement in which the bone spins on a longtiudinal axis is called:
elbow bent, move forearm to place palm agains your abdomen, your humerus spins in a motion called:
the oppostite motion where forearm points away from body, the humerus exhibits:
medial (internal) rotation
lateral( external) rotation
a movement that turns the palm to face anteriorly or upward is called:
the opposite movement, causing the palm to face posteriorly or downward is called:
a movement that decreases a joint angle, usually in the sagittal plane is called:
a movement that straightens a joint and generally returns a body part to the zero position is called:
the further extension of a joint beyond the zero position is called:
tilting the head or turnk to the right or left of the midline is called:
twisting at the waist or turing the head is called:
right or left rotation
the side to side movement of the madible is called:
the hand tilted towards the little finger is called
the hand tilted towards the thumb is called:
Degree of movement:
Degree of movement: multiaxial
Description: most moveable, extend/hyperextend/flexion, largest degree of rotation
Example: Sholder, Knee
Pivot Degree of movement:
Degree of movement: monaxial
Description: bone spins on logititudional axis
Example: C1 + C2, radialulnar
Saddle Degree of movement:
Degree of movement: Biaxial
Description: both bones are shaped like a saddle
Example: trapezio/metacarpals, sternoclavical
Hinge Degree of Movement:
Degree of movement: monaxial
Description: convex peice fits into a concave peice
Example: knee, elbow, interphalanges
Plane Degree of Movement:
Degree of movement: monaxial
Description: Rotate, slide over each other, limited motion, significant motion when combind in a group
Example: intercarples of wrist
Condylar Degree of movement:
Degree of movement: biaxial
Description: convex fits into a concave, oval
Example: Raidalcarpal, metacarpals/phalanges
