Notes: Directional Terms (pg 8)

Anatomical Position: Standing upright, face and feet forward, arms at sides with palms facing forward

Body Cavities

• Dorsal cavity: Contains brain and spinal cord

Body Cavities

• Dorsal cavity: Contains brain and spinal cord• Ventral cavity: Contains thoracic (chest) cavity

and abdominal cavity

Directions in the Body

• Superior = Above (closer to the head)

• Inferior = Below (closer to the feet)

Directions in the Body

• Superior = Above (closer to the head)

• Anterior = toward the front (ventral)

• Inferior = Below (closer to the feet)

• Posterior = toward the back (dorsal)

Directions in the Body

• Superior = Above (closer to the head)

• Anterior = toward the front (ventral)

• Medial = near the midline of the body

• Inferior = Below (closer to the feet)

• Posterior = toward the back (dorsal)

• Lateral = near the side of the body

Directions in the Body

• Superior = Above (closer to the head)

• Anterior = toward the front (ventral)

• Medial = near the midline of the body

• Proximal = close to a point of attachment

• Inferior = Below (closer to the feet)

• Posterior = toward the back (dorsal)

• Lateral = near the side of the body

• Distal = far from a point of attachment

Directions in the Body

• Superior = Above (closer to the head)

• Anterior = toward the front (ventral)

• Medial = near the midline of the body

• Proximal = close to a point of attachment

• Superficial = near the surface

• Inferior = Below (closer to the feet)

• Posterior = toward the back (dorsal)

• Lateral = near the side of the body

• Distal = far from a point of attachment

• Deep = away from the surface

Using directional terms

• Terms describe the position of a part relative to another part

• Incorrect: The heart is superior• Correct: The heart is superior to the intestines

Output (pg 9)

Describe the classroom using the directional terms (1 sentence per term)

Example: The pencil sharpener is lateral to the desks

Partner Activity

• One person will point to a body part. The other will say whether that part is:superior/inferioranterior/posteriorlateral/medial

Relative to the person’s noseThen switch partners. Repeat for 5 body parts

each

Planes (pg 8)

Planes

• Sagittal plane: vertical plane that divides the body into right and left sides

Planes

• Sagittal plane: vertical plane that divides the body into right and left sides

• Transverse plane: horizontal plane that divides the body into superior and inferior portions (cross section)

Planes

• Sagittal plane: vertical plane that divides the body into right and left sides

• Transverse plane: horizontal plane that divides the body into superior and inferior portions (cross section)

• Frontal (coronal) plane: vertical plane that divides the body into anterior and posterior portions

Activity

• Use the modeling clay to sculpt a small elephant (each person makes their own)

• When finished, call me over to your table and show me the sagittal, transverse, and frontal planes
