The spelling of "incisura clavicularis" may appear daunting at first glance. Its pronunciation is /ɪnˈsɪzjʊərə kləˌvɪkjʊˈlærɪs/, which can be broken down into individual sounds. The first syllable, "in," is pronounced like the word "sin." "Cisura" is pronounced with a soft "c" and an "s" sound, followed by "ura" which is pronounced like "you-rah." "Clavicularis" is pronounced with emphasis on the second syllable, and the "si" sounds like "sigh." Despite its complexity, mastering the pronunciation can aid in clear communication and understanding within the field of anatomy.
Incisura clavicularis refers to a specific anatomical feature located in the clavicle, which is commonly known as the collarbone. The term "incisura" comes from the Latin word meaning "notch" or "indentation", while "clavicularis" relates to the clavicle bone of the human body.
More specifically, the incisura clavicularis is the small, shallow groove or depression found on the upper surface of the clavicle, near its middle portion. This concave region is typically positioned medially (towards the body's midline) and is bordered by two distinct structures: the conoid tubercle anteriorly and the trapezoid line posteriorly.
The incisura clavicularis serves as an attachment point for the conoid and trapezoid ligaments, both of which play crucial roles in stabilizing the clavicle joint. These ligaments connect the clavicle to the scapula (shoulder blade) and are part of the coracoclavicular ligament complex, which contributes to providing stability and support for the shoulder joint.
Understanding the precise location and anatomical aspects of the incisura clavicularis is essential for medical professionals, such as orthopedic surgeons, anatomists, and radiologists, who specialize in diagnosing and treating conditions related to the clavicle. Overall, this specific anatomical feature plays a crucial role in ensuring the stability and range of motion of the shoulder joint.
The clavicular notch or facet, a hollow at either side of the upper surface of the manubrium sterni articulating with the clavicle.

The word "incisura clavicularis" has Latin roots. It is a combination of two Latin terms:
1. "Incisura": This word originates from the Latin verb "incidere", which means "to cut into" or "to notch". The noun form "incisura" refers to a notch, indentation, or cut.
2. "Clavicularis": This term is derived from the Latin word "clavicula", which means "clavicle" or "collarbone". The suffix "-aris" indicates a relationship or association.
Therefore, "incisura clavicularis" can be understood to mean the "clavicular notch" or the "notch of the clavicle". It refers to a concave area or notch located on the superior border of the clavicle bone where it articulates with the acromion process of the scapula.
