Which branch of the facial nerve innervates the orbicularis oculi?
Buccal branch
Temporal branch
Mandibular branch
Cervical branch
The temporal branch of the facial nerve curves over the zygomatic arch to innervate the orbicularis oculi and frontalis. Damage to this branch can impair eyelid closure. Knowledge of these branches is key in facial reanimation surgeries. https://www.ncbi.nlm.nih.gov/books/NBK540969/

Mandible
Maxillary bone
Zygomatic bone
Frontal bone
Zygomaticus major originates from the posterior surface of the zygomatic bone. It then runs inferiorly and medially to insert at the mouth’s angle. This origin allows it to elevate the mouth corner effectively. https://www.getbodysmart.com/ap/muscular/face/zygomaticus/
Which muscle’s origin is the fascia over the pectoralis major and deltoid, inserting into the lower mandible and skin of the lower face?
Risorius

Orbicularis oris
Risorius
Levator palpebrae superioris
Depressor anguli oris
The levator palpebrae superioris is innervated by the oculomotor nerve (cranial nerve III), not the facial nerve. It elevates the upper eyelid. Facial nerve innervates superficial facial muscles, whereas this is a skeletal extraocular muscle. https://en.wikipedia.org/wiki/Levator_palpebrae_superioris_muscle
The buccal branch of the facial nerve primarily innervates which of these muscles?
Masseter
Buccinator
Temporalis
Sternocleidomastoid
The buccal branch of the facial nerve supplies the buccinator, orbicularis oris, and other midface muscles. It does not innervate muscles of mastication like masseter or temporalis. This branch courses above the parotid gland. https://www.ncbi.nlm.nih.gov/books/NBK539785/
Which muscle has its insertion at the modiolus of the mouth, a fibromuscular structure at the angle of the lips?
Orbicularis oculi
Risorius
Depressor anguli oris
Zygomaticus major
The depressor anguli oris inserts at the modiolus, the convergence of facial muscles at the mouth’s corner. This insertion point allows it to pull the mouth downward. The modiolus is crucial for complex lip movements. https://www.sciencedirect.com/science/article/pii/S1877132711002243

It is innervated by the buccal branch of the facial nerve. https://en.wikipedia.org/wiki/Levator_labii_superioris_alaeque_nasi_muscle
Which muscle aids in grimacing and has no bony attachments, lying in the superficial fascia of the cheek?
Buccinator
Platysma
Risorius
Zygomaticus major
The risorius has no direct bony attachments and is situated in the superficial fascia of the cheek. It pulls the mouth’s corner laterally, creating a sideways grin or grimace. Its unique location distinguishes it from other cheek muscles. https://en.wikipedia.org/wiki/Risorius_muscle
Which embryological branchial arch gives rise to the muscles of facial expression?
First branchial arch
Second branchial arch
Third branchial arch
Fourth branchial arch
Muscles of facial expression develop from the mesenchyme of the second branchial (pharyngeal) arch. This arch’s neural crest cells differentiate under Hox gene influence. Their innervation by the facial nerve reflects this embryology. https://www.ncbi.nlm.nih.gov/books/NBK542254/
In facial nerve palsy, which muscle’s paralysis can lead to drooping of the angle of the mouth and difficulty with lip closure?
Orbicularis oris
Buccinator
Depressor anguli oris
Corrugator supercilii
Paralysis of the depressor anguli oris prevents the downward pull on the mouth corner, causing asymmetry and drooping. This contributes to impaired articulation and drooling. Assessing its function helps localize damage in Bell’s palsy. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3711478/
Which muscle forms the medial boundary of the parotid gland and is pierced by Stensen’s duct?
Masseter
Buccinator
Zygomaticus minor
Risorius
Stensen’s duct pierces the buccinator to drain saliva from the parotid gland into the oral cavity. The buccinator’s position forms the medial border of the gland. Injury to the duct or muscle can impair saliva flow. https://en.wikipedia.org/wiki/Parotid_duct

Cheat Sheet

  1. Orbicularis Oculi -

    The orbicularis oculi encircles the eye and is responsible for blinking and gentle eyelid closure. According to Gray's Anatomy and NIH physiology references, its palpebral part handles involuntary blinking, while the orbital part enables forceful winking. Remember "O for Ocular circle" to nail the facial muscle labeling around the eye.

  2. Zygomaticus Major & Minor -

    These paired muscles extend from the zygomatic bone to the mouth corners, elevating the lips to produce a smile. University of California's Anatomy Lab notes the major is larger and more lateral, while the minor sits above it for subtle lip movements. Use the mnemonic "Major smiles big, Minor's a little grin" to streamline face muscle labeling tasks.

  3. Buccinator -

    Located deep in the cheek, the buccinator compresses the cheek during chewing and aids in whistling. Research in the Journal of Anatomy highlights its role in maintaining food between the teeth and stabilizing the cheek against overexpansion. Picture a "trumpeter's cheek" to quickly spot it in any facial muscles quiz.

  4. Frontalis & Corrugator Supercilii -

    The frontalis raises the eyebrows and wrinkles the forehead, while the corrugator supercilii draws the eyebrows together into a frown. The American Association of Anatomists describes them as part of the epicranius, linked by the galea aponeurotica. Remember "Brow duo: Frontalis high, Corrugator low" for your next muscles of facial expression quiz.

  5. Platysma -

    This superficial neck muscle tenses the skin of the lower face and neck, contributing to expressions like horror or surprise. NIH musculoskeletal guidelines emphasize its role in depressing the mandible and lower lip. Keep "Platysma's plait on the neck" in mind to label face muscles clearly.
