The spine is located on the posterior (dorsal) side of the body, essentially running down the back.
In more detail:
-
Posterior Location: The spine is positioned along the posterior, or backside, of the torso. Imagine a line drawn from the head down the middle of the back; the spine follows this line.
-
Dorsal Location: "Dorsal" is another term for the posterior side. Therefore, the spine resides on the dorsal aspect of the body.
-
Protection: Its posterior position is advantageous for protection, as the back tends to be less exposed than the front of the body.
-
Central Support: While located on the back, the spine serves as the central support structure for the entire body.
