|---|---|---|---|---|---|
| JOINT SURFACE MOTION; in other words, the manner in which adjoining joint surfaces move on each other during osteokinematic joint movement: | arthrokinematics
🗑
|
||||
| JOINT MOTION; how bones move in space: | osteokinematics
🗑
|
||||
| Axial movements done under voluntary control: | Voluntary osteokinematic motion (also known as classic or physiologic)
🗑
|
||||
| Resistance at the end range of a voluntary motion is called _______ ________. | end feel
🗑
|
||||
| Linear movements WITHIN THE JOINT & surrounding tissues that are necessary for normal ROM, but can not be voluntarily performed: | Accessory motion
🗑
|
||||
| Motions that accompany active motion, but are not under voluntary control: | component motion (a type of accessory motion)
🗑
|
||||
| Passive movements between joint surfaces done by passively applying EXTERNAL FORCE (not under voluntary control): | joint play (a type of accessory motion)
🗑
|
||||
| The type of accessory motion occurring at the joint depends on the ________ of the articulating surfaces. | shape
🗑
|
||||
| Pertaining to shape, ALL joint surfaces are either _________ or ________. | ovoid or sellar
🗑
|
||||
| Pertaining to shape, most synovial joints are ________. | ovoid
🗑
|
||||
| An oviod joint has two bones forming a ________-_________ relationship. | convex-concave ie)metacarpophalangeal joints
🗑
|
||||
| In a _________ shaped joint, each joint surface is concave in one direction and convex in another | sellar (or 'saddle-shaped')ie) the MCP joint of the thumb
🗑
|
||||
| Name the types of accessory (arthrokinematic) motion: | Roll, Glide, and Spin (or combo of all three)
🗑
|
||||
| The type of arthrokinematic motion in which new points on one surface meet new points on the opposing surface throughout the motion; always in the same direction as the moving bone: | Roll ie) shoe on floor during walking
🗑
|
||||
| This type of arthrokinematic motion results in compression on one side of the joint and separation on the other; surfaces are incongruent: | Roll
🗑
|
||||
| The type of arthrokinematic motion that is a linear movement of a joint surface parallel to the plane of the adjoining joint surface: | Glide (or Slide)
🗑
|
||||
| The type of arthrokinematic motion in which the same point on one surface comes into contact with new points on the opposing surface; the surfaces are congruent. | Glide (or slide)
🗑
|
||||
| The direction of gilding (sliding) depends on whether the moving surface is __________ or __________. | concave or convex
🗑
|
||||
| The type of arthrokinematic motion is the rotation of a movable joint surface on a FIXED adjacent surface, often occurs in combination: | spin
🗑
|
||||
| During this type of arthrokinematic motion, the same point on each surface remains in contact with each other: | spin
🗑
|
||||
| Describe the convex-concave rule: | - The concave joint SURFACE moves in the same direction as the body segment's motion. - The convex joint SURFACE moves in the opposite direction of the body segment's movement.
🗑
|
||||
| Name the 4 types of Accessory Motion forces: | traction, compression, shearing, rotary
🗑
|
||||
| ________ may also be called distraction or tension or tensile. This is the joint motion that occurs when outside force pulls joint surfaces away from each other. | Traction
🗑
|
||||
| Also called approximation; joint movement that occurs when external force pushes joint surfaces closer together: | Compression
🗑
|
||||
| This accessory motion force causes bone ends to move parallel to and in opposite direction from each other: | Shear
🗑
|
||||
| The twisting motion that is a combination of compression and shear: | Rotary
🗑
