Anatomical Position

▪ Anatomical Position:

• Used for the purpose of description

• Body is standing, the feet together, the arms to the side, and the head and eyes and palms of the hands facing forwards.

5

Anatomical Planes

▪ Anatomical Planes: Flat surfaces which pass through body parts–The Main Planes

1. Sagittal (parasagittal and midsagittal)

2.Frontal3.Transverse

6

Anatomical Planes

1. Sagittal: a cut made lengthwise (longitudinal) that divides the body into left and right halve–Midsagittal–Parasagittal

7

Anatomical Planes

2. Frontal Plane:

• A cut made lengthwise that divides the body into anterior and posterior parts (front and back)

8

Frontal

9

Anatomical Planes

3. Transverse Plane:

• Cut made along a horizontal plane, dividing the body into superior and inferior parts (top and bottom)

• AKA a cross section

Body Cavities

▪ Dorsal Body Cavities:

• Cranial Cavity• Space inside the

skull• Contains the brain

• Spinal Cavity• Extends from the

cranial cavity down the vertebral column

• Contains the spinal cord

Body Cavities

▪ Ventral Body Cavities:

• Thoracic Cavity• The upper body

cavity that extends down to the diaphragm

• Abdominopelvic Cavity• Abdominal cavity• Pelvic cavity
