What does pecten mean?
A pecten is a structure marked by a series of parallel or radiating ridges. In human anatomy, the term usually refers to the pecten pubis, the comb-like part of the pubic bone formed by projecting ridges. In zoology, it may denote one of the ribs or folds on the shell of a scallop or another bivalve mollusk, and it can also be used for the animal itself in older or specialized classifications. The word comes from Latin pecten, meaning “comb,” an apt description for both the pubic structure and the shell’s radiating ridges. It is uncommon in general conversation but useful in anatomy, paleontology, and mollusk studies, where its precise anatomical sense matters.
nounA comb-like anatomical structure, especially the ridged, comb-shaped part of the pubic bone. The term is also used for the shell ridges of scallops and related bivalve mollusks.
- A comb-like structure in the pubic bone, composed of a set of projecting ridges.
- A ridge or series of ridges running along the shell of a bivalve mollusk, especially a scallop.
- A scallop or similar bivalve mollusk, especially in classical biological usage.
"The pecten of the pubic bone is made up of multiple projecting ridges."
"The pecten is visible on the inner surface of the pubic bone."
"Each valve of the scallop shell is marked by radiating ribs, or pectens."
The plural pectens is used in specialized anatomical and zoological contexts; some individual anatomical structures are referred to by Latinized forms.
"The pectens of several bivalves form prominent radiating ribs."
From the Latin for “comb,” the pecten takes its name from the comb-like ridges of a scallop shell and a similarly ridged part of the pubic bone.

Where does pecten come from?
The English word comes from Latin pecten, meaning “comb” or “comb-like thing,” referring to a structure with regularly spaced teeth or ridges. The same Latin root underlies pectin and the adjective pectinate, both of which preserve the idea of a comb-like arrangement. Latin pecten also gave rise to the anatomical expression pecten pubis, literally the “pubic comb.”

How pecten is actually used
This is primarily a specialized anatomical and zoological term. In medical anatomy, “pecten” most often refers to the pecten pubis; in zoology, it can refer to a shell ridge or to the mollusk itself.
