anatomy general

Question 1

flexor muscle

Answer 1

any of the muscles that decrease the angle between bones on two sides of a joint, as in bending the elbow or knee

Question 2

extensor muscle

Answer 2

any of the muscles that increase the angle between members of a limb, as by straightening the elbow or
knee or bending the wrist or spine backward

Question 3

anterior (ventral)

Answer 3

near the front

Question 4

posterior (dorsal)

Answer 4

near the back

Question 5

superior (cranial)

Answer 5

upward or near the head

Question 6

inferior (caudal)

Answer 6

downward or near the feet

Question 7

medial

Answer 7

toward the midline or median plane

Question 8

median plane/mid sagittal plane

Answer 8

divides the body into equal right and left parts

Question 9

sagittal plane

Answer 9

divides the body into unequal left n right parts

Question 10

lateral

Answer 10

farther from the midline or median plane

Question 11

superficial

Answer 11

closer to the surface

Question 12

deep

Answer 12

farther from the surface

Question 13

proximal

Answer 13

situated close to the origin/pnt of attachment/median line of body/centre of the body

Question 14

distal

Answer 14

opposite proximal

Question 15

frontal (coronal) plane

Answer 15

divides body into equal or unequal anterior and posterior parts

Question 16

transverse plane

Answer 16

divides body into equal or unequal superior and inferior parts

Question 17

spheroidal joint

Answer 17

Rotations in 3 axes

eg hip joint

Question 18

ellipsoid joint

Answer 18

Rotations in 2 axes (subequal range-ie one way more than the other)
eg radiocarpal joint

Question 19

saddle joint

Answer 19

Rotations in 2 axes (approx equal range)

eg carpal metacarpal joint in thumb

Question 20

hinge joint

Answer 20

Rotation in 1 axis (at right angles to long axis of articulating bones)
e.g. some joints in elbow

Question 21

pivot joint

Answer 21

Rotation in 1 axis (parallel with long axis of articulating bones)
eg proximal radioulnar joint

Question 22

plane joint

Answer 22

Small translations

eg acromioclavicular joint
