MUSCULI PECTINATI Meaning and
Definition
-
Musculi pectinati, derived from the Latin words "musculi" (meaning muscles) and "pectinati" (meaning comb-like), refers to a specific anatomical structure within the human heart. It is a term used to describe the unique muscular arrangement found in the walls of the atria, also known as the upper chambers of the heart.
The musculi pectinati are thin, parallel muscular ridges that resemble the teeth of a comb. They are mainly characterized by their prominent appearance and location within the atrial walls. These ridges are composed of interconnected cardiac muscle fibers and are observed primarily in the right atrium, although they can also be found in the left atrium to a lesser extent.
The arrangement of musculi pectinati plays a crucial role in the functioning of the heart. They increase the surface area of the atrial walls, allowing for greater contact and interaction between the atria and the blood. This enhances the conduction of electrical signals and promotes efficient contraction of the atria during the cardiac cycle.
While musculi pectinati primarily serve as a structural component, they can occasionally play a role in pathophysiology. For example, an abnormal enlargement or excessive growth of these ridges may result in a condition called pectinate muscles hypertrophy, which can potentially impact the function of the heart.
In summary, musculi pectinati are comb-like muscular ridges found in the walls of the atria, aiding in the efficient conduction of electrical signals and coordinated contraction of the heart's upper chambers.

Etymology of MUSCULI PECTINATI
The term "Musculi Pectinati" is derived from Latin.
- "Musculi" is the plural form of "musculus", which means "muscle" in Latin.
- "Pectinati" is the plural form of "pectinatus", an adjective form of "pecten", meaning "comb" or "comb-like".
Therefore, "Musculi Pectinati" translates to "comb-like muscles" in English. This term is commonly used to refer to the muscular ridges found in the wall of the right atrium of the heart. These ridges have a comb-like appearance, hence the name.
