The correct spelling of the term "septum pectiniforme" may be tricky due to its long Latin roots. However, it can be broken down phonetically using the International Phonetic Alphabet. The first word, "septum," is pronounced /ˈsɛptəm/. The second word, "pectiniforme," can be broken down into three parts: "pec-ti-ni-form-e," and pronounced as /ˈpɛktɪnɪfɔːrm/. Overall, "septum pectiniforme" refers to a particular anatomical structure found in certain fish species, characterized by its comb-shaped appearance.
Septum pectiniforme is a Latin term used in anatomy to describe a specific structure located within the human heart. The term "septum" refers to a dividing wall or partition, while "pectiniforme" is derived from the Latin word "pectin" meaning comb-like or toothed in appearance.
The septum pectiniforme, also known as the pectinate muscle or muscular ridge, is a prominent anatomical feature found in the atria of the heart. It is characterized by a series of irregular muscular ridges that extend along the inner surface of the atrial walls. These ridges have a distinct comb-like or toothed appearance, hence the name pectiniforme.
The primary function of the septum pectiniforme is to increase the surface area within the atria, thereby facilitating effective atrial contraction during cardiac cycles. This muscular structure provides additional strength to the atrial walls, ensuring efficient blood flow and preventing any backward flow or regurgitation.
The septum pectiniforme can be found in both the left and right atria of the heart. In the right atrium, it is particularly prominent in the region known as the auricle, which is an appendage-like extension. In the left atrium, this structure is less pronounced.
Understanding the anatomy and function of the septum pectiniforme is crucial for medical professionals, as it aids in diagnosing and treating certain cardiac conditions, such as atrial fibrillation and atrial flutter.

The term "septum pectiniforme" is a Latin phrase used in anatomy. Here is the breakdown of the etymology:
- Septum: The word "septum" comes from Latin and means "a fence" or "a partition". It is derived from the Latin verb "septare", which means "to enclose" or "to separate".
- Pectiniforme: The word "pectiniforme" is also Latin in origin. It is derived from the Latin noun "pecten", which means "a comb". The suffix "-iforme" is a Latin suffix used to indicate the shape or form of something, so "pectiniforme" means "having the shape of a comb".
When combined, "septum pectiniforme" refers to a structure or formation in the shape of a comb-like partition or barrier.
