The term "tuberositas humeri" is a medical term that refers to the bony eminence of the humerus bone. It is pronounced as /tjuːbərɒsɪtəs hjuːˈmɛri/ and spelled as "t-u-b-e-r-o-s-i-t-a-s h-u-m-e-r-i". The first part of the word "tuberositas" is derived from the Latin word "tuber" meaning swelling or knob, while the second part "humeri" refers to the humerus bone. The correct spelling of this term is important in medical documentation and communication to accurately describe the anatomic location.
Tuberositas humeri refers to a specific anatomical feature located in the upper extremity of the human body, specifically in the humerus bone. It is a bony prominence or protuberance found on the anteromedial aspect of the upper arm bone. The tuberositas humeri is also commonly known as the lesser tubercle of the humerus.
This anatomical structure plays an essential role in the attachment of various muscles and ligaments in the shoulder and arm region. Specifically, the subscapularis muscle, one of the four rotator cuff muscles, attaches to the tuberositas humeri through a strong tendon. This muscle aids in the internal rotation of the shoulder joint.
The tuberositas humeri has a rounded shape, often described as a small bony bump or protuberance. It is positioned slightly below the more prominent greater tubercle of the humerus, which is located on the lateral aspect of the bone. Together, these two tubercles provide attachment sites for the muscles and tendons involved in the movements and stability of the arm.
Overall, the tuberositas humeri serves as an important anatomical landmark for understanding the structure and function of the upper arm. Its well-defined shape and position make it easily identifiable in clinical and anatomical examinations.

The term "tuberositas humeri" is derived from Latin and consists of two words: "tuberositas" and "humeri".
1. "Tuberositas" comes from the Latin word "tuberosus", which means "swelling" or "knob". It is derived from the word "tuber", which refers to a protuberance or swelling on the surface of something. In medical terminology, "tuberositas" specifically refers to a prominence or roughened area on a bone.
2. "Humeri" is the genitive form of the Latin word "humerus", which means "upper arm" or "shoulder". It is a Latinized form of the Greek word "omos", which carries the same meaning.
