CAROTID TUBERCLE Meaning and
Definition
-
Carotid tubercle is a prominent bony projection located on the anterior aspect of the transverse process of cervical vertebrae, specifically the sixth cervical vertebra (C6). This tubercle acts as an important landmark and serves as an attachment site for several structures in the neck region.
The carotid tubercle is situated at the superior aspect of the transverse process of C6, just lateral to the anterior tubercle. It is positioned at the level of the carotid bifurcation, where the common carotid artery branches into the external and internal carotid arteries. This anatomical landmark is palpable and allows healthcare professionals to accurately locate and evaluate the carotid arteries during certain medical procedures.
Significant structures attach to the carotid tubercle, including the prevertebral layer of deep cervical fascia, anterior scalene muscle, and the medial margin of the omohyoid muscle. These attachments contribute to the stability and support of the carotid arteries and nearby structures.
Knowledge of the carotid tubercle is particularly useful during surgical procedures of the neck, head, and upper thorax where the carotid artery needs to be identified, accessed, or avoided. Furthermore, understanding the relationships and attachments associated with the carotid tubercle aids in the accurate interpretation of imaging studies, such as X-rays or CT scans, in clinical practice.

Etymology of CAROTID TUBERCLE
The etymology of the word "carotid tubercle" originates from two different origins: carotid and tubercle.
1. Carotid: The term "carotid" comes from the Greek word "karōtides", which means "great arteries" or "main arteries". It is derived from the Greek word "karos", which means "deep sleep" or "stupor". The reference to "deep sleep" might be due to the temporary unconsciousness that can be experienced when the carotid arteries are compressed.
2. Tubercle: The word "tubercle" has its roots in the Latin word "tuberculum", which means "small swelling" or "little bump". It is derived from the Latin word "tuber", which means "swelling" or "protuberance".
