PLATYSMA Meaning and
Definition
-
The platysma is a broad and thin sheet of muscle located in the front of the neck and extending down to the upper chest. It is a superficial muscle that covers the lower part of the face, mandible, and the neck. The term "platysma" is derived from the Greek word "platys," meaning flat, and "sma," meaning sheet or layer.
The platysma muscle is considered a facial expression muscle and plays a crucial role in various movements of the face and neck. It acts mainly in facial expressions by pulling down the corners of the mouth and lower lip, creating a downward and tense appearance. It also aids in expressions of sadness, aggression, and fear.
In addition to its role in facial expressions, the platysma muscle also assists in swallowing and helps to stabilize the neck during certain movements. It is innervated by the facial nerve (cranial nerve VII) and receives its blood supply from branches of the facial artery.
The platysma muscle can become prominent and tense during intense expressions or muscular exertion. It may also become more visible or prominent in some individuals with weight loss or aging, creating visible vertical bands in the front of the neck, which are sometimes referred to as "platysma bands."

Etymology of PLATYSMA
The word "platysma" originates from the Ancient Greek term "platysma" (πλάτυσμα) which means "something broad" or "broad muscle". It is derived from the Greek word "platýs" (πλατύς) that translates to "broad" or "wide". The suffix "-ma" in Greek is used to indicate a "result" or "product", so "platysma" refers to the "broad muscle" found in the neck region.
