![]() The muscle that encircles the orbit is the orbicularis oculi muscle. There is one muscle that encircles the orbit. Laterally to each orbit is a lateral orbital fat pad. The superior fat pad is superior to the orbit, but inferior to the eyebrows, while the inferior orbital fat pad is inferior to the orbit and it contributes to the fullness in the superior cheek region. Deep to the skin over the eye region are the fat pads. The eyelids cover and provide eyes with protection. At the edges of the eyelids are the eyelashes. The eyelids divide into the upper and lower eyelids. Surrounding and covering the eyes are the eyelids. ![]() The skin that is directly superior to the orbits is also the region where the eyebrows are found. The eyes situate in the orbital sockets in the upper face region. The bony structure of the forehead is made up of the frontal bone predominantly, while the lateral region of the upper face that corresponds to the temporal part forms from the temporal and sphenoid bone. The contraction of the temporalis muscle results in the elevation and retraction of the mandible. The temporalis muscle inserts on the coronoid process and the retromolar fossa. The temporalis muscle originates from the parietal and sphenoidal bone. The contraction of the corrugator supercilii muscle results in the wrinkling of the forehead. The corrugator supercilii muscle is a small muscle that originated from the supraorbital ridge and inserts on the skin of the forehead close to the eyebrows. The action of the depressor supercilii muscle is to depress the eyebrows. The depressor supercilii muscle originates from the medial orbital rim and inserts at the medial part of the bony orbit. When the occipitofrontalis muscle contracts, it elevates the eyebrows and wrinkles the forehead. The occipitofrontalis muscle originated from the galea aponeurosis superiorly and inserts and blends into the orbicularis oculi muscle. The occipitofrontalis muscle spans the majority of the forehead. The contraction of the procerus muscle allows for the elevation of the eyebrows. The procerus muscle is situated between the eyebrows and attaches to the frontalis muscle. The procerus muscle is shaped like a pyramid and spans from the inferior part of the nasal bone to the middle part of the forehead. The procerus muscle occipitofrontalis muscle, depressor supercilii muscle, and corrugator supercilii muscle form the majority of the forehead, while the temporal part contains the temporalis muscle. The muscular layer of the upper face is underneath the fat pads. ![]() The lateral temporal fat pad overlies the temporal regions and spans inferiorly to the angle of the mandible. The fat pad that makes up the most lateral region of the upper face is the lateral temporal fat pad. The middle forehead fat pad is superior to the orbits. Laterally to the central forehead pad is the middle forehead fat pad. The central forehead fat pad is in the center of the forehead. Deeper to the skin layer of the forehead is the fat pads. The superficial layer of the forehead is made up of skin. The forehead is the superior region of the upper face region. The upper face region contains the forehead, eyes, and temporal region. ![]() The lateral borders of the upper face terminate around the temporal region. The region that is considered the upper face starts from the hairline superiorly and ends just under the lower eyelid. The entire face is covered by skin superficially, while the deep anatomy contains muscles, fat pads, nerves, vessels, and bones. The anatomy of the face can divide into three main regions: upper face, middle face, and lower face.
