The word "Platysma Myoides" is a term used in anatomy, specifically to describe a muscle in the neck. The spelling of this word can be a bit tricky, so let's break it down using phonetic transcription. "Platysma" is pronounced [pləˈtɪzmə], with the stress on the second syllable. "Myoides" is pronounced [maɪˈɔɪdiːz], with the stress on the first syllable. When spoken together, the phrase is pronounced [pləˈtɪzmə maɪˈɔɪdiːz]. Remembering the pronunciation of both words will help us spell the term correctly.
The term "platysma myoides" refers to a specific muscle located in the subcutaneous layer of the neck and lower face. Also known simply as the platysma, it consists of thin, broad, and flat muscular bands that are bilateral and symmetrical. The name "platysma myoides" is derived from the Greek words "platys," meaning "broad," and "mys," meaning "muscle."
The platysma myoides muscle originates from the fascia of the chest and extends upwards towards the lower portion of the face, specifically the region around the mouth. It covers the front part of the neck and is responsible for various movements and expressions in this area. When the platysma contracts, it draws down the lower lip and angles of the mouth, causing the characteristic appearance of tension in the neck and chin. It assists in actions such as chewing, facial expressions involving the lower face, and movements associated with swallowing.
The platysma myoides muscle receives innervation from the cervical branch of the facial nerve (cranial nerve VII). It receives its blood supply primarily from the superior thyroid artery and sometimes the facial artery. The muscle also has connections with other neck muscles, including the sternocleidomastoid and the depressor anguli oris.
Understanding the anatomy and function of the platysma myoides muscle is crucial for medical professionals in fields such as surgery, neurology, and rehabilitation.
The word "Platysma Myoides" consists of two parts: "Platysma" and "Myoides".
1. "Platysma" is derived from the Greek word "platos" (πλατύς), meaning "broad" or "flat", and "ma" (μα), a suffix commonly used in anatomy to refer to a muscle. In this context, "Platysma" refers to the platysma muscle, a broad, thin muscle located in the neck area.
2. "Myoides" is derived from the Greek word "mys" (μῦς), meaning "muscle", and "oides" (οΐδης), meaning "like" or "resembling". Therefore, "Myoides" signifies that something resembles or relates to a muscle.
