The pectoral ridge is a bony protrusion located on the chest of many animals, including humans. The word "pectoral" is spelled with the phonetic symbols /pɛkˈtɔːrəl/ and the stress is placed on the second syllable. The sound /p/ is followed by the open-mid back unrounded vowel /ɛ/. The consonant cluster /ct/ is pronounced as /kt/. The second syllable contains the long open-mid back unrounded vowel /ɔː/, followed by the alveolar approximant /r/. The final syllable /əl/ is pronounced as the schwa sound.
The term "pectoral ridge" refers to a anatomical feature found in the human body. It is a distinct ridge or bulge that runs horizontally across the upper part of the chest, specifically in the pectoral region. This ridge is primarily formed by the pectoralis major muscle, which is a large, fan-shaped muscle that covers the upper portion of the chest. It is attached to the collarbone, across the upper arm, and ribs, contributing to various movements of the shoulder joint.
The "pectoral ridge" is commonly visible in individuals who have well-developed pectoral muscles, such as bodybuilders or athletes who engage in upper body strength training exercises. It is often considered as a sign of physical fitness and muscularity. This prominent ridge is formed by the increased mass and thickness of the pectoralis major muscle, usually resulting from regular resistance training and muscle hypertrophy.
Furthermore, the pectoral ridge can also vary in appearance among individuals, depending on several factors such as genetics, body composition, and overall level of physical activity. Some people may have a more pronounced and defined ridge, while others may have a less noticeable ridge.
In summary, the pectoral ridge is a distinct bulge or raised area in the upper chest formed by the pectoralis major muscle. It is commonly associated with individuals who have well-developed pectoral muscles due to regular strength training and muscle hypertrophy.

The word "pectoral" comes from the Latin word "pectus", which means "chest" or "breast". It is derived from the Proto-Indo-European root "*peḱu-", meaning "breast" or "to swell".
The word "ridge", on the other hand, traces its origins back to the Old English "hrycg", which means "back" or "ridge". It can be further traced to the Proto-Germanic word "*hrugjaz", meaning "ridge" or "spine".
Therefore, the term "pectoral ridge" combines the Latin root for "chest" and the Old English word for "ridge", describing a prominent, raised structure or line on the chest.
