Latin muscle parts
Brachial muscle – anterior compartment
In English, this muscle’s name is the crow arm muscle. What does this odd translation of the Latin mean? Let’s examine this in a little more detail to clarify.The term coraco- in the muscle’s name is from the Greek corax meaning “raven or crow.” The ancient anatomist Galen thought that the anterior projection of the scapula, called the coracoid process, resembled a raven or crow perched on a branch, so he referred to it as the crow-like process. This muscle arises from this crow-like process and annexes the term as part of its name.The brachialis portion of the name refers to the fact that it courses into and ends in the brachium from the Latin term brachium, which derives from the Greek brachion meaning “arm,” in reference to the region of the upper limb between the shoulder and the elbow.
Coracoid process of the scapula
