How Do You Spell TUBEROSITAS DELTOIDEA?

1. Tuberositas deltoidea is a medical term that refers to a bony prominence located on the lateral surface of the humerus bone, specifically at its distal end. The humerus is the long bone in the upper arm that extends from the shoulder to the elbow joint. The tuberositas deltoidea is also known as the deltoid tuberosity because it serves as an attachment site for the deltoid muscle.

   The deltoid tuberosity is most noticeable when the arm is extended at the shoulder joint. It appears as an oblong elevation or ridge and is positioned in the upper third of the humerus bone. The deltoid muscle, which covers the shoulder joint, inserts onto this bony prominence, providing strength and stability to the arm. The muscle fibers of the deltoid originate from the collarbone and shoulder blade, forming a thick mass that tapers towards the tuberositas deltoidea.

   In addition to muscle attachment, the tuberositas deltoidea plays a critical role in transmitting forces between the upper arm and the forearm. It serves as a point of leverage for the deltoid muscle during arm movements such as lifting and throwing. The prominence of this bony landmark aids in appropriately distributing the tension generated by muscular contraction, contributing to the smooth functioning of the upper limb. Overall, the tuberositas deltoidea is a salient anatomical feature that is pivotal for the proper functioning and mobility of the arm.

2. Deltoid tuberosity or eminence, a rough elevation about the middle of the outer side of the shaft of the humerus, giving attachment to the deltoid muscle.

Common Misspellings for TUBEROSITAS DELTOIDEA

The word "tuberositas deltoidea" is derived from Latin.

- "Tuberositas" means tuberosity, which refers to a bony prominence or projection on a bone.

- "Deltoidea" is a compound word, with "deltoid" and "-ea" as its components. The term "deltoid" comes from the Greek word "deltoeides", meaning triangular. In anatomy, the deltoid muscle is so named due to its triangular shape as it attaches to the humerus (arm bone). The suffix "-ea" is a feminine form in Latin, indicating "of or pertaining to".

Therefore, "tuberositas deltoidea" is a Latin term used in anatomy to describe the bony prominence related to the deltoid muscle, specifically referring to the deltoid tuberosity on the humerus.
