FASCICULUS OCCIPITOFRONTALIS Meaning and
Definition
-
The term "fasciculus occipitofrontalis" refers to a specific anatomical structure found in the human body. It is a band or bundle (fasciculus) of muscle fibers that is located in the occipital and frontal regions of the head.
More specifically, the fasciculus occipitofrontalis is a muscle group that is responsible for various movements and expressions of the forehead and scalp. It consists of two parts: the occipitalis and the frontalis.
The occipitalis portion of the fasciculus occipitofrontalis is located at the back of the head, originating from the occipital bone. It inserts into the superficial fascia on top of the skull. This muscle primarily functions to allow the scalp to move backward, aiding in facial expressions like surprise or raising the eyebrows.
On the other hand, the frontalis portion of the fasciculus occipitofrontalis is located in the frontal region of the head. It originates from the cranial aponeurosis, a tough fibrous layer covering the skull. The frontalis muscle inserts into the eyebrows and the skin of the forehead. Its main function is to enable the scalp to move forward, allowing for furrowing of the eyebrows and wrinkling of the forehead during expressions like frowning or concentration.
In summary, the fasciculus occipitofrontalis is a muscle bundle consisting of the occipitalis and frontalis, responsible for various movements and expressions of the forehead and scalp.

Etymology of FASCICULUS OCCIPITOFRONTALIS
The term "fasciculus occipitofrontalis" is derived from Latin, with each element having its own etymology:
1. Fasciculus: The word "fasciculus" comes from the Latin word "fascis", which means "bundle" or "cluster". It is a diminutive form of "fascis" and refers to a small bundle or a collection of nerve fibers or muscle fibers.
2. Occipitofrontalis: "Occipitofrontalis" is a compound word made up of two Latin roots.
The first part, "occipito", refers to the occipital bone, which is located at the back of the skull. It derives from the Latin word "occiput", meaning "back of the head".
The second part, "frontalis", is related to the frontal bone, which forms the forehead.
