The glenoid surface is an important anatomical feature of the shoulder joint. But how do you pronounce it correctly? The word "glenoid" is pronounced [gliːnɔɪd] with emphasis on the first syllable, and the "oi" sound is similar to the "oy" in "boy". "Surface" is pronounced [sɜːfɪs], with emphasis on the first syllable and a long "er" sound in the second syllable. So, if you want to impress your anatomy teacher or sound like a proffesional when discussing shoulders, make sure to get the pronunciation of "glenoid surface" right!
The glenoid surface is a term commonly used in anatomy and orthopedics to refer to a specific area of the scapula or shoulder blade. More specifically, it refers to the shallow, concave portion of the scapula that articulates with the humeral head to form the glenohumeral joint. This joint is a key component of the shoulder and allows for a wide range of motion.
The glenoid surface is characterized by its smooth, curved shape, which is important for facilitating the movement of the humeral head during shoulder movements. It is covered with a layer of articular cartilage, which helps to reduce friction and cushion the joint during motion.
The glenoid surface plays a crucial role in maintaining the stability and function of the shoulder joint. It provides a stable and congruent surface for the humeral head to glide on, allowing for smooth and coordinated movements. The shape and orientation of the glenoid surface also contribute to the overall stability of the shoulder joint, helping to prevent dislocation and other injuries.
In summary, the glenoid surface is the shallow, concave portion of the scapula that articulates with the humeral head to form the glenohumeral joint. It is vital for the stability and function of the shoulder joint, allowing for a wide range of motion and facilitating smooth, coordinated movements.
A slightly concave oval surface on the head of the scapula, forming with the g. ligament the g. fossa.

The word "glenoid" comes from the Greek word "glēnē", meaning "socket", and the word "oid", meaning "like" or "resembling". Therefore, "glenoid" can be understood to mean "socket-like" or "resembling a socket".
The word "surface" originated from the Latin word "superficies", which means "outer side, exterior". It evolved through Old French and Middle English before taking its current form.
When combined, "glenoid surface" refers to the smooth, concave area of the scapula (shoulder blade) that resembles a socket. It is part of the glenohumeral joint, where the head of the humerus (upper arm bone) articulates.
