The spelling of the anatomical term "tuberositas supraglenoidalis" can seem daunting at first glance. However, by using the International Phonetic Alphabet (IPA) phonetic transcription, we can break it down into manageable parts. "Tuberositas" is pronounced "tʊbɛrɔːˈsaɪtəs," while "supraglenoidalis" is pronounced "suːprəɡlɪˈnɔɪdəlɪs." The word refers to a bony prominence above the glenoid cavity of the scapula. By understanding the IPA phonetic transcription, one can more easily navigate and understand complex medical terminology.
Tuberositas supraglenoidalis is a term derived from Latin anatomical nomenclature. It refers to a bony prominence located on the superior aspect of the glenoid fossa of the scapula bone. The glenoid fossa is a concave structure that serves as a socket for the head of the humerus bone, forming part of the shoulder joint.
The tuberositas supraglenoidalis can be described as a small, rounded elevation or tubercle situated just above the glenoid fossa. This prominence acts as an attachment site for several important structures, including the long head of the biceps brachii muscle. The tendons of the long head of the biceps travel through a groove, known as the intertubercular groove or bicipital groove, and attach to the tuberositas supraglenoidalis.
This anatomical feature is of significance due to its involvement in shoulder stability and movement. The attachment of the long head of the biceps muscle to the tuberositas supraglenoidalis plays a role in flexing and supinating the forearm. Additionally, it helps to stabilize the head of the humerus within the glenoid fossa, preventing excessive translation or displacement during arm movements.
In summary, the tuberositas supraglenoidalis is a small bony prominence found above the glenoid fossa of the scapula, serving as an attachment site for the long head of the biceps muscle and contributing to shoulder stability and movement.
Supraglenoid tuberosity or tubercle, a rough surface above the glenoid cavity of the scapula, giving attachment to the tendon of the long head of the triceps.

The term "tuberositas supraglenoidalis" is derived from Latin and Greek roots. The word "tuberositas" comes from the Latin word "tuberosus", meaning "full of swellings" or "knobby". "Supraglenoidalis" is derived from the Latin word "supra", meaning "above", and "glenoidalis", which relates to the glenoid cavity. In the context of anatomy, the term refers to a bony prominence or tubercle located above the glenoid cavity of the scapula (shoulder blade).
