MOVEMENT

BODY POSITIONS
 When we describe body position, we assume the person is in
anatomical position.
 Body is upright, with the person facing forward, feet flat on the
ground, arms at the side, and palms facing forward.
REGIONS
 Principle regions of the body
 Head
 Skull
 Face
 Trunk
 Chest
 Abdomen
 Pelvis
 Upper limbs
 Lower limbs
BODY PLANES
 When the body is in anatomical position, it can be divided into
three imaginary planes. These planes help clarify and specify
movements.
 Sagittal Plane: Divides the body into right and left portions.
 Frontal (or coronal) Plane: Divides the body into front (anterior) and
back (posterior) portions.
 Transverse Plane: Divides the body into upper (superior) and lower
(inferior) parts.
DIRECTIONAL TERMS
 In order to locate various body structures, anatomists use
specific body directional terms.
 Describe the position of one body part in relation to another.
Directional Term

Example
Superior
Toward the head
The head is superior to the
neck
Inferior
Away from the head
The belly button is inferior
to the chest
Anterior
Posterior
Medial
Lateral

Anterior
Nearer to or at the front of
the body
The knee cap is on the
anterior side of the body.
Posterior
Nearer to or at the back of
the body
The shoulder blade is on
the posterior side of the
body.

Anterior
Nearer to or at the front of
the body
The eyes are anterior to
the brain
Posterior
Nearer to or at the back of
the body
The brain is posterior to
the eyes
Medial
Nearer to the midline
The pinky is medial to the
thumb
Lateral
Farther from the midline
The thumb is lateral to the
pinky

Ipsilateral
On the same side of the
The right shoulder is

Contralateral
On the opposite side of
the body as another
structure
Proximal
Distal
Superficial
Deep
Example
The right shoulder is
contralateral to the left
hip

Proximal
Nearer to the attachment
of a limb to the trunk
The shoulder is proximal
to the wrist
Distal
Farther from the
attachment of a limb to
the trunk
The elbow is distal to the
shoulder

BODY CAVITIES
 Body cavities are spaces within the body that help protect,
separate, and support internal organs.
 Cranial cavity: Formed by the cranial bones and contains the brain.
 Vertebral cavity: Formed by the vertebrae and contains the spinal
cord.
 Thoracic cavity: Formed by the ribs and contains the heart and lungs.
 Abdominopelvic cavity: contains all other internal organs.
PLAY-DOH LAB!
1. Choose a partner.
2. Come get toothpicks (14), play -doh, a knife, and tape from me.
3. Make a person out of play -doh (they have to have a head, a
trunk, two arms and two legs). Please put a face on your
person.
4. Stick a toothpick in the most superior aspect of the person.
5. Make a transverse cut through the person’s navel.
6. Make a frontal cut through the person’s head.
7. Make a sagittal cut through the person’s left (your right) leg.
8. On the person’s right arms and legs, mark the most proximal
and distal portions. Also, mark the medial and lateral portions.
9. Label the anterior and posterior portions of the person’s head.
10. Everything in RED needs to be toothpicked and labeled!
11. Have me come check when you’re done!
BODY MOVEMENTS
