BICEPS EXTERNUS MUSCULUS Meaning and
Definition
-
The biceps externus musculus is a Latin term often used in anatomy to describe a specific muscle in the human body. It refers to a particular muscle in the upper arm region, which is commonly known as the brachii muscle or biceps brachii. The term "externus" indicates that this muscle is positioned externally or on the outer side of the arm.
The biceps externus musculus is a prominent muscle that plays a significant role in upper limb movement and stability. It is located in the anterior compartment of the arm and is easily recognizable due to its characteristic shape. It consists of two heads, namely the long head and the short head, both of which originate from different parts of the scapula or shoulder blade.
The primary function of the biceps externus musculus is to flex the forearm at the elbow joint, allowing the arm to bend. It is also involved in supination, a movement that turns the palm upward. Additionally, this muscle assists in maintaining stability during activities that require strength, such as lifting objects or performing pulling movements.
Overall, the biceps externus musculus is a crucial muscle for upper limb strength, flexibility, and stability. It is an essential component of the musculoskeletal system and contributes significantly to the overall functionality of the arm.
