flexion

 [flek´shun]
1. the act of bending or the condition of being bent.
2. in obstetrics, the normal bending forward of the head of the fetus in the uterus or birth canal so that the chin rests on the chest, thereby presenting the smallest diameter of the vertex.
plantar flexion bending of the toes or foot downwards toward the sole.

flex·ion

(flek'shŭn), [TA] Avoid the misspelling flection.
1. The act of flexing or bending, for example, bending of a joint to approximate the parts it connects; bending of the spine so that the concavity of the curve looks forward.
2. The condition of being flexed or bent.
[L. flecto, pp. flexus, to bend]

flexion

(flĕk′shən)
n.
1. also flection Anatomy
a. The act of bending a joint or limb in the body by the action of flexors.
b. The resulting condition of being bent.
2. A part that is bent.

flexion

[flek′shən]
Etymology: L, flectere, to bend
1 a movement allowed by certain joints of the skeleton that decreases the angle between two adjoining bones, such as bending the elbow, which decreases the angle between the humerus and the ulna. Compare extension.
2 a resistance to the descent of the fetus through the birth canal that causes the neck to flex so the chin approaches the chest. Thus the smallest diameter (suboccipitobregmatic) of the vertex presents.

1. The act of bending of a joint or other part or the state of being bent.
2. Pertaining to a bent part as in flexion deformity.

flexion

a movement which decreases the joint angle between two ventral surfaces of the body, e.g. bending the elbow or knee, tilting the head forwards. flexor muscles those with this action, e.g. biceps, hamstrings. Opposite of extension. Figure 1.

flexion

joint movement, causing the flexor aspects of the body parts it connects to move towards one another

Flexion.
flexion, bilateral sacral,
n condition in which the sacrum has rotated around a central transverse axis so that the sacral base moves forward between the bones of the pelvis. Also called
sacral base anterior.
flexion, craniosacral,

flexion, sacral,
n anterior movement of the sacral base relative to the hip bones.
flexion, SBS,
n rotation of the occipital and sphenoid bones in opposing directions about parallel transverse axes, thus resulting in superior positioning of the basilar portion of both bones and an increase in the posterior convexity between them. Also called
sphenobasilar synchondrosis (symphysis) flexion.
