Abdominal CAT scans are often transverse plane slices like a stack of coins. The regions are named below and the corresponding regions are labeled Pennate muscles are usually found where their length change is less important than maximum force, such as the rectus femoris.

For example, blood can be said to flow in a proximal or distal direction, and anteroposterior, mediolateral, and inferosuperior axes are lines along which the body extends, like the X, Y, and Z axes of a Cartesian coordinate system. Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation.

Patentmeaning a structure such as an artery or vein that abnormally remains open, such as a patent ductus arteriosusreferring to the ductus arteriosus which normally becomes ligamentum arteriosum within three weeks of birth.

The elbow is superior above to the hand. Three planes are commonly referred to in anatomy and medicine:Anatomical directional terms are like the directions on a compass rose of a map.

Like the directions, North, South, East and West, they can be used to describe the locations of structures in relation to other structures or locations in the body.
