Topic: nurs190 - musculoskeletal + neuro
1. what are the bone shapes?
Answer: - long (eg. femur, humerus) - short (eg. carpals, tarsals) - flat (eg. parietal bone of
the skull, sternum, ribs) irregular (eg. vertebrae, hip bones)
2. what is a plane joint?
Answer: - the articular surfaces are flat, allowing only slipping or gliding movements\ - eg:
intercarpal and intertarsal joints and the joints between the articular processes of the ribs
3. what is a hinge joint?
Answer: - a convex projection of one bone fits into a concave depression in another - permit
flexion and extension only - eg: elbow and knee joints
4. what is a pivot joint?
Answer: - the rounded end of one bone protrudes into a ring of bone (and possibly
ligaments) - only movement allowed is rotation of the bone around its own long axis or
against the other bone - eg: joint between atlas and axis of the neck
5. what is a condyloid joint?
Answer: - oval surfaces of two bones fit together - movements allowed are flexion and
extension, abduction, adduction, and circumduction - eg: radiocarpal (wrist) joints
6. what is a saddle joint?
Answer: - each articulating bone has both concave and convex areas (resembling a saddle) -
opposing surfaces fit together - movements allowed are the same as for condyloid joints, but
the freedom of motion is greater eg: carpometacarpal joints of the thumbs
7. what is a ball-and-socket joint?
Answer: - ball-shaped head of one bone fits into the concave socket of another - allow
movement in all axes and planes, including rotation - eg: shoulder and hip joints
8. what is gliding?
Answer: -simplest type of joint movements - one flat bone surface glides or slips over
another similar surface - the bones are merely displaced in relation to one another
9. what is flexion?
Answer: bending movement that decreases the angle of the joint and brings the articulating
bones closer together
10. what is extension? increases
Answer: the angle between the articulating bones
11. what is hyperextension?
Answer: bending of a joint beyond 180 degrees
12. what is dorsiflexion?
Answer: flexion of the ankle so that the superior aspect of the foot approaches the shin
Page 1
, 13. what is plantar flexion?
Answer: extension of the ankle (pointing the toes)
14. what is abduction?
Answer: - movement of a limb away from the midline or median plane of the body, along the
frontal plane - when the term is used to describe movement of the fingers or toes, it means
spreading them apart
15. what is adduction?
Answer: - movement of a limb toward the body midline - bringing the fingers close together
is adduction
16. what is circumduction?
Answer: - movement in which the limb describes a cone in space - distal end of the limb
moves in a circle, whereas the joint itself moves only slightly in the joint cavity
17. what is rotation?
Answer: - turning movement of a bone around its own long axis - rotation may occur toward
the body midline or away from it
18. what is supination?
Answer: movement of the forearm so that the palm faces anteriorly or superiorly
19. what is pronation?
Answer: the palm moves to face posteriorly or inferiorly
20. what is inversion? the
Answer: sole of the foot is turned medially
21. what is eversion?
Answer: the sole faces laterally
22. what is protraction?
Answer: nonangular anterior movement in a transverse plane
23. what is retraction? nonangular
Answer: posterior movement in a transverse plane
24. what is elevation? a
Answer: lifting or moving superiorly along a frontal plane
25. what is depression?
Answer: when the elevated part is moved down ward to its original position
26. what is opposition?
Answer: - only allowed at the saddle joint of the thumb between metacarpal 1 and the
carpals - it is the movement of touching the thumb to the tips of the other fingers of the
same hand
27. what does PA of the musculoskeletal system include?
Answer: - inspection - palpation
28. what is a muscle strength of 0?
Answer: no muscle contraction
