Anatomical Terminology
Directional Terms
• Used by medical personnel and anatomists allowing them to explain exactly where on body structure is in relation to another.
• We would say: The ears are located on each side of the head to the right and left of the nose.
• Using anatomical terminology: The ears are lateral to the nose.
• 1. The wrist is ________ to the hand.• 2. The breastbone is ___________ to the
spine.• 3. The brain is __________ to the spinal cord.• 4. The lungs are ___________ to the stomach.• 5. The mouth is ___________ to the nose.

Body Planes & Sections
• When preparing to look at internal structures of the body, medical students make a section or a cut. When the section is made through the body wall or an organ, it is made along an imaginary line called a plane.
Body Planes/Sections
• 1. Saggital- seperates body into left and right sides
• 2. Frontal- seperates body or organ into anterior and posterior parts
• 3. Transverse- seperates organ into superioir and inferior parts
Body planes
All together now
Wait…what? (Connect!)
• Sagittal
• Transverse
• Coronal
• Horizontal
• Median
• Frontal
With your creature…
• Show me a Sagittal Section
Sagittal/Median plane divides body into?
• Show me a frontal section
Coronal/frontal plane divides body into?
• Show me a transverse section
Transverse/horizontal plane divides body into?
All together now for real

Body Cavities
• 1. Dorsal (protected by bone)– Cranial- contains brain– Spinal- contains spinal cord
• 2. Ventral– Thoracic- contains heart & lungs– Abdominopelvic• Abdominal- contains digestive organs (not protected by
bone)• Pelvic- contains reproductive organs, bladder, rectum
