1

What is the anatomical position?

The anatomical position refers to the human body as erect (standing), facing forward with eyes straight ahead, arms at the sides with palms open and facing forward, and feet parallel and flat on the floor.

2

Which plane divides the body into front and back sections?

Frontal/Coronal plane

3

Which plane divides the body into left and right sides in a vertical lengthwise fashion?

Sagittal plane

4

Which plane divides the body into right and left equal sections?

Median/Midsagittal plane.
This imaginary line is the midline of the body

5

Which plane divides the body into top and bottom sections?

Transverse horizontal plane
A horizontal plane situated at right angles to the long axis, or sagittal and coronal planes; placed crosswise.

6

What are the three ventral cavities?

Ventral cavities contain organs on the front side of the body. They are the Thoracic, Abdominal, and Pelvic cavities.

7

What are the two dorsal cavities?

Dorsal cavities contain organs on the back side of the body. They are the Cranial and Spinal cavities.

8

What are the five vertebral divisions of the of the back/spinal column?

Cervical vertebrae (C1 - C7)
Thoracic vertebrae (T1 - T12)
Lumbar vertebrae (L1 - L5)
Sacrum
Coccyx

9

Medial

Pertaining to the middle; closer to the midline of a body; pertaining to the middle layer.

10

Lateral

Pertaining to the side; denoting a position farther from the midline (median plane) of a structure.

11

Distal

Remote; farther from the center of the body or point of attachment to the body; opposite of proximal. (The elbow is distal to the shoulder, but proximal to the wrist.)

12

Proximal

Nearest; closer to the center of the body or point of attachment to the body; opposite of distal. (The elbow is distal to the shoulder but proximal to the wrist.)

13

Supine

lying horizontally on the back, face up

14

Prone

lying face down on the abdomen

15

Supination

opposite of pronation. Rotating the palm forward/anteriorly. Can also refer to the outward roll of the foot during normal motion.

16

Pronation

Rotating the palm backwards/posteriorly. Can also refer to the inward roll of the foot during normal motion and occurs as the outer edge of the heel strikes the ground and the foot rolls inward and flattens out.

17

Plantar

of, relating to, or typical of the sole of the foot. the plantar aspect of the foot.

18

Posterior

Situated in the back; also used in reference to the back or dorsal surface of the body.

19

Ventral

Pertaining to the abdomen; used to denote a position that is more toward the belly/abdominal surface than some other object of reference.

20

Superior

Situated above, or directed upward; in official anatomic nomenclature, used in reference to the upper surface of an organ or other structure, or to a structure occupying a higher position.

21

Inferior

Situated below a structure or directed downward; also used to denote the lower portion of an organ or the lower of two structures.

22

Cranial

aka. Superior
above or upward toward the head

23

Caudal

aka. Inferior

24

Inferior

Situated below a structure or directed downward; also used to denote the lower portion of an organ or the lower of two structures.

25

Coronal

Division of the body into anterior and posterior sections. Also called frontal plane. Can mean pertaining to the head or the crown

26

Caudal

aka. Inferior
Situated below a structure or directed downward

27

Deep (internal)

Situated further inward, away from the surface.

28

Midline

the Median/Midsagittal plane

29

Flexion

Bending motion of joint at an angle that decreases the distance between two bones. (Bending your knee/elbow)

30

Extension

Bending motion of joint at an angle that increases the distance between two bones. (Straightening your arm/leg)
