Study Notes
Facial Muscles
- The masseter is not primarily a muscle of facial expression, unlike the buccinator, depressor labii, risorius, and mentalis.
- The mentalis muscle inserts onto the skin of the chin, playing a role in facial expression.
Kissing Muscle
- The orbicularis oris is known as the "kissing muscle" and is responsible for pursing the lips.
Innervation
- The levator palpebrae superioris muscle is not innervated by the facial nerve (N VII), while the others listed are.
Muscle Origins and Insertions
- The origin of the frontalis muscle is on the epicranial aponeurosis.
- The temporalis muscle passes through the zygomatic arch.
- The sternocleidomastoid muscle inserts on the mastoid process of the temporal bone.
Anterior Neck Muscles
- The platysma covers the anterior surface of the neck and is important for facial expressions.
Eye Muscles
- The inferior rectus muscle allows movement to look down, while the superior rectus permits looking up.
- The medial rectus muscle is responsible for medial rotation of the eyeball.
- The superior oblique muscle sends its tendon through a pulley before inserting on the eye.
Antagonistic Pairs
- The trapezius and sternocleidomastoid muscles function as antagonistic pairs in head movement.
Chewing and Manipulation
- The masseter, temporalis, and pterygoid muscles are involved in chewing, while the omohyoid is not associated with this activity.
Treatment for Strabismus
- The medial rectus muscle may be cut to correct strabismus (crossed eyes).
Muscles for Trumpet Playing
- For trumpet playing, developing the buccinator and orbicularis oris would be beneficial to enhance performance.
Neck and Back Muscles
- The trapezius muscle when moved exposes the rhomboid and levator scapulae muscles, essential for shoulder and neck tension management.
- The trapezius muscle inserts on the acromion and scapular spine, playing a key role in shoulder movement.
