For improved clarity, the directional term palmar (from Latin palma 'palm of the hand') is commonly used to describe the front of the hand, and dorsal is the back of the hand. For example, the top of a dog 's paw is its dorsal surface; the underside, either the palmar (on the forelimb) or the plantar (on the hindlimb) surface.
By using precise anatomical terms, such as "proximal," "distal," "palmar," or "dorsal," this ambiguity is eliminated, ensuring clear communication. To standardize this system of terminology, Terminologia Anatomica was established as an international reference for anatomical terms.
For example, "Able Seaman Smith; lie aft!" or "What's happening aft?". Comparative is "after", e.g. "the mizzenmast is after than the mainmast". The difference between "aft" and "stern" is that aft is the inside (on board) rearmost part of the vessel, while stern refers to the outside (offboard) rearmost part of the vessel. The stern is ...
[1] [2] The positions of the limbs (and the arms in particular) have important implications for directional terms in those appendages. The penis in the anatomical position is described in its erect position and therefore lies against the abdomen, hence the dorsal surface of the penis is actually anterior when the penis is flaccid.

the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks. The regions of the back of the arms, from superior to inferior, include the cervical region encompassing the neck, the acromial region encompassing the shoulder,
For example, bending the elbow, or clenching a hand into a fist, are examples of flexion. When a person is sitting down, the knees are flexed. When a person is sitting down, the knees are flexed. When a joint can move forward and backward, such as the neck and trunk, flexion is movement in the anterior direction. [ 10 ]
The tattooed corpse of a woman was found bizarrely stuffed in a refrigerator dumped in some New Jersey woods — and cops say they need the public’s help identifying her.
However, the situation is more complex, since comparative embryology shows that the length axis of the neural tube (the primordium of the brain) has three internal bending points, namely two ventral bendings at the cervical and cephalic flexures (cervical flexure roughly between the medulla oblongata and the spinal cord, and cephalic flexure ...
