EMINENTIA ARTICULARIS Meaning and
Definition
-
Eminentia articularis is a term used in anatomy to describe a prominent or projecting structure found in relation to a joint. Generally, it refers to a bony prominence or ridge that serves an important role in joint function and movement.
In the context of the human skeleton, the eminentia articularis can be found in certain joints such as the temporomandibular joint (TMJ). In the TMJ, the eminentia articularis refers to a prominent ridge located on the temporal bone of the skull, acting as an articulating surface for the mandible or lower jaw. This bony projection ensures stability and proper alignment of the joint during the opening and closing of the mouth.
The term can also be used more broadly to describe similar structures in other joints. For instance, in the knee joint, the eminentia articularis can refer to a prominence on the end of the tibia bone, known as the tibial spine or intercondylar eminence. It serves as an attachment point for important ligaments and contributes to the stability and movement of the knee joint.
Overall, the eminentia articularis is a significant feature in joint anatomy, playing a crucial role in facilitating proper joint movement, stability, and function.

Etymology of EMINENTIA ARTICULARIS
The word "eminentia articularis" is a Latin term used in anatomy that translates to "articulating prominence" in English.
- "Eminentia" comes from the Latin word "eminentia", which means "eminence" or "prominence". It is derived from the verb "emineo", meaning "to project" or "to stand out".
- "Articularis" is derived from the Latin word "articulus", which means "joint" or "jointed", and the suffix "-aris", indicating "pertaining to" or "related to".
So, the etymology of "eminentia articularis" suggests a combining of the Latin terms for "prominence" and "joint", referring to a feature or prominence related to a joint.
