Flashcards in Anatomy (p.4-1) Deck (34):
1

Abduction

take extremities (arms and legs) away from the midline

2

Fascia

-continuous sheet located directly beneath the skin, throughout the body -firm when cool, more pliable when warm

3

Protraction

move toward front midline of body

4

Transverse Plane

twisting (Rotation)

5

Antagonist

muscle(s) directly opposite (on the other side of the joint) as to the agonist/primary muscle(s)

6

Eccentric Contraction

muscle engagement during active muscle lengthening (e.g. triceps in Chaturanga when lowering to Low Plank)

7

Depression

move down toward feet

8

Frontal Plane

side to side (Abduction, Adduction, Inversion, Eversion)

9

Hyperextension

extending joint beyond neutral position

10

Co-contraction

Agonist and antagonist are simultaneously active. Muscle co-contraction increases joint stability and facilitates joint control.

11

Sagittal Plane

forward and back (Flexion, Extension)

12

Inversion

moving sole of foot toward medial plane (e.g. back foot in Warrior I)

13

Plantarflexion

Move the top of the foot away from the shin (e.g. point your toes)

14

Adduction

take extremities (arms and legs) toward the midline

15

Agonist

primary muscle(s) responsible for the desired motion at a joint

16

Tendons

-connect muscle to bone (connects fascia of muscles to fascia of bones) -thicker version of fascia

17

Concentric Contraction

muscle engagement during active muscle shortening (e.g. rectus abdominus when moving up in Basic Crunch)

18

Elevation

lift up towards head

19

Kyphosis

curve towards back body - thoracic spine, sacral spine

20

Rotation

rotary movement in hips, shoulders, spine (external/lateral vs internal/medial rotation)

21

Isometric Contraction

muscle engagement under constant muscle length without movement (e.g. rectus abdominus in Boat Pose)

22

Axial Skeleton

skull, sternum, ribs, spine

23

Eversion

moving sole of foot away from medial plane

24

Ligaments

-connect bone to bone at a joint -thicker version of fascia -stabilize joint, control mobility -limited to no elasticity. Over-stretching or injury to ligaments compromises the stability potential of a joint.

25

Extension

straightens or opens a joint (e.g. backbend)

26

Supination

external rotation resulting in appendage facing up

27

Retraction

move toward back midline of body

28

Flexion

bends a joint or brings the bones closer together (e.g. curling your body into a ball, fetal pose, forward fold)

29

Appendicular Skeleton

shoulder girdle, pelvic girdle, upper and lower extremities

30

Lordosis

curve towards front body - cervical spine, lumbar spine

31

Circumduction

circular movement (e.g. drawing a circle with your arm)

32

Stabilizer

muscle(s) that hold a joint in place while the exercise is being performed and the main muscles are supported.

33

Pronation

internal rotation resulting in appendage facing down

34

Dorsiflexion

Move the top of the foot towards the shin (Warrior I front leg, Malasana Frog)
