The stylohyoid muscle is a long, slender muscle belonging to the suprahyoid muscle group. It extends from the styloid process of the temporal bone to the hyoid bone and contributes to hyoid bone movements during swallowing, speech, and respiration. Anatomy Morphology and Connection Points The stylohyoid muscle, a long and slender muscle, is located in the upper part of the neck, anterosuperior to the posterior belly of the digastric muscle. It extends from the styloid process of the temporal bon

Depressor Anguli Oris is a facial muscle that plays a significant role in facial expressions. It originates from the lateral surface of the mandible (lower jaw) and inserts into the angle of the mouth (modiolus). It contributes to the formation of expressions such as frowning and sadness. Anatomical Structure Morphology and Attachment Points The depressor anguli oris is a flat, triangular, superficial muscle that arises along the oblique line of the mandible, just below the mental foramen. Its f

The Orbicularis Oculi Muscle is a sphincter (ring-shaped) muscle that surrounds the eyelids and enables them to be closed. Its contracting fibers originate from the nasal portion of the frontal bone, the frontal process of the maxilla, and the anterior surface and borders of the medial palpebral ligament. These fibers are widely distributed around the eye, forming a thin, broad muscle layer extending toward the temples and cheeks. Anatomy Morphology and Connection Points The Orbicularis Oculi Mu

Platysma muscle is a thin, broad muscle located in the superficial layer of the neck. It plays a role in facial expressions, mandibular movements, and tensioning of the neck skin. It is innervated by the facial nerve (CN VII) and is an important structure in aesthetic surgery. Anatomical Structure Morphology and Attachment Points The platysma muscle is a thin, broad superficial muscle that originates from the fascia overlying the pectoralis major and deltoid muscles and extends upward to the upp

The levator anguli oris is a facial muscle located in the oral region that contributes to the formation of smiling and similar facial expressions. It originates from a specific depression on the anterior surface of the maxilla and extends to the corner of the mouth, where it blends with other facial muscles. Anatomical Structure The muscle originates from the canine fossa of the maxilla. This origin point is located immediately below the infraorbital foramen. Its fibers run downward and laterall
