The muscle fibers compose the eyelids as they travel towards the lateral commissure of the eye.
MUSCLEMATICS VS IMUSCLE SKIN
The upper fibers merge with the occipitofrontalis, corrugator supercilii and depressor supercilii muscles, finally inserting into the skin and subcutaneous tissue of the eyebrow. The orbital part has no bony insertions, but instead it attaches to various soft tissue structures of the periorbital region. The fibers encircle the orbit completely, extending into the soft tissues of adjacent regions. Orbital part: overlays the orbital rim and originates from the nasal part of frontal bone, frontal process of maxilla and medial palpebral ligament.It is composed of orbital, palpebral and deep palpebral parts, each of which has its own specific set of attachments: Orbicularis oculi is a flat, broad muscle that forms an ellipse around the circumference of the orbit. This article will describe the anatomy and functions of the orbicularis oculi muscle. Maxillary, superficial temporal, facial and ophthalmic arteries. Temporal and zygomatic branches of facial nerve (CN VII)
Skin of orbital region, lateral palpebral raphe, superior and inferior tarsal platesÄeep palpebral part: Compresses lacrimal sac Nasal part of frontal bone, frontal process of maxilla, medial palpebral ligament, lacrimal bone Key facts about the orbicularis oculi muscle Origin Depending on the degree and frequency of closure, this action can be essential for hydrating the eye, protecting it or non-verbally conveying a message with a cheeky wink. Under the control of the facial nerve (cranial nerve VII), orbicularis oculi closes the eye. The muscle extends between three bones of the viscerocranium ( frontal bone, maxilla, lacrimal bone) and the soft tissue structures of the periorbital region. Orbicularis oculi consists of an orbital, palpebral and deep palpebral part. Together with corrugator supercilii and levator palpebrae superioris, it belongs to the circumorbital and palpebral group of muscles that surround the eye. Orbicularis oculi is a paired facial muscle that surrounds each orbit and the adjacent periorbital region. Orbicularis oculi muscle (musculus orbicularis oculi)
