The correct spelling of the anatomical term "tuberositas infraglenoidalis" is tricky due to its Latin origin and complex structure. In IPA phonetic transcription, it is pronounced as /tuˌbɛrɒsɪtəs ˌɪnfrəɡliːnɔɪˈdeɪlɪs/. It refers to a rounded, bony protrusion just below the shoulder joint. Professionals in the medical field need to spell and pronounce such technical terms with precision, as inaccurate usage can lead to misunderstandings or errors in diagnoses and treatments.
Tuberositas infraglenoidalis is a medical term primarily used in the field of anatomy and physiology. It refers to a bony prominence situated below the glenoid fossa of the scapula, also commonly known as the shoulder blade. The tuberositas infraglenoidalis serves as an attachment site for various muscles and ligaments, specifically the long head of the triceps brachii muscle.
The tuberositas infraglenoidalis is located on the posterior aspect of the scapula and is characterized by its elevation and rough texture. It is positioned slightly inferiorly to the glenoid fossa, which is a shallow, concave depression that articulates with the head of the humerus to form the shoulder joint.
This anatomical feature plays a critical role in shoulder movement as it serves as the origin site for the long head of the triceps brachii muscle. The long head of the triceps brachii arises from the tuberositas infraglenoidalis and extends down the posterior aspect of the arm, eventually inserting onto the olecranon process of the ulna bone.
Understanding the structure and location of the tuberositas infraglenoidalis is essential for healthcare professionals, particularly orthopedic surgeons, physical therapists, and sports medicine practitioners, as it aids in the diagnosis, treatment, and management of various conditions affecting the shoulder joint.

The term tuberositas infraglenoidalis is derived from Latin and Greek roots. Here is the etymology breakdown:
1. Tuberositas - Latin word meaning tuberosity, which refers to a prominence or bump on a bone.
2. Infra - Latin prefix meaning below or under.
3. Glenoidalis - The adjective form of the Latin word glenoid, which means socket. It typically refers to the glenoid fossa of the scapula (shoulder blade).
Therefore, tuberositas infraglenoidalis can be translated as the tuberosity below the glenoid fossa.
