Verticalis muscle (highlighted in red)

The Verticalis muscle is a small muscle located in the human head. It is one of the muscles that make up the occipitofrontalis, which is responsible for various facial expressions.

Structure

The verticalis muscle originates from the galea aponeurotica, a tough layer of dense fibrous tissue which covers the upper part of the cranium. It inserts into the skin of the eyebrows and the root of the nose.

Function

The verticalis muscle is responsible for moving the scalp forward and raising the eyebrows. This action is often associated with expressions of surprise or curiosity.

Clinical significance

Damage to the verticalis muscle can result in a loss of ability to raise the eyebrows, which can affect facial expressions. This can be a symptom of certain neurological conditions, such as Bell's palsy.
