Body Directions and Planes Unit 1 Body Directions and Planes
Anatomical position is always: Upright Facing forward Arms extended Palms foward
4 key directions: 1. Dorsal: back side 2. Ventral: underside 3. Anterior: head end 4. Posterior: rear or tail end
How do the 4 main directions work if the organisms is a two legged human?
Some other “must know” directional terms include: Cranial Superior Medial lateral proximal distal caudal
There are also 4 Key Planes of the body frontal / coronal transverse / cross 3. Sagittal 4. Median (mid-sagittal)
Let’s see if we can ID the sectional cut shown below
It’s a coronal section
How about this one?
This one shows a Sagittal Section
and this one??
This is a Transverse Section
