Depressor supercilii muscle

Depressor supercilii muscle is a small muscle located in the facial region of the human body. It is considered part of the orbicularis oculi muscle group, which is responsible for various movements of the eye and eyebrow.

Etymology

The term "depressor supercilii" is derived from Latin, where "depressor" means "one that lowers" and "supercilii" refers to the eyebrow. Thus, the name of the muscle reflects its function, which is to lower the eyebrow.

Anatomy

The depressor supercilii muscle originates from the medial orbital rim and inserts into the medial part of the orbicularis oculi muscle. It is innervated by the facial nerve, specifically the temporal branch and the zygomatic branch.

Function

The primary function of the depressor supercilii muscle is to pull the eyebrow downward, contributing to facial expressions such as frowning. It also assists in the closure of the eye by pulling the skin of the forehead towards the eyelid.

Clinical significance

Due to its role in facial expressions, the depressor supercilii muscle is often targeted in cosmetic surgery and Botox treatments to reduce the appearance of frown lines and wrinkles. Additionally, damage to the facial nerve can result in paralysis of the depressor supercilii muscle, leading to conditions such as Bell's palsy.
