Muscles that control the shape and movements of the mouth and lips.

A strong and flexible connective tissue structure where many muscles insert, which is located at the corners of the mouth.

This muscle is located in the cheek and helps compress the cheeks during sucking and whistling.

This circular muscle surrounds the mouth and controls lip movement.

This muscle pulls the corners of the mouth laterally, creating a smile.

This muscle depresses the corners of the mouth, contributing to frowning.

This muscle arises from the zygomatic bone and pulls the corners of the mouth upwards, contributing to smiling.

They are the only group of muscles that insert into the skin, allowing them to create facial expressions by pulling on the skin.

A quadrangular muscle situated in the chin region.

The Depressor Labii Inferioris Muscle originates from the oblique line of the mandible.

The Depressor Labii Inferioris Muscle inserts into the skin and submucosa of the lower lip.

The Depressor Labii Inferioris Muscle's primary action is to depress the lower lip inferolaterally.

The Depressor Labii Inferioris Muscle is innervated by the mandibular branch of the facial nerve.

The Depressor Labii Inferioris Muscle receives blood supply from the inferior labial branch of the facial artery and the mental branch of the maxillary artery.

A slender, strap-like muscle located on both sides of the nose.

Paired conical facial muscle found in the chin.

The facial nerve (CN VII) controls the muscles of the face, including those around the eyelids. Damage to the facial nerve can cause paralysis of these muscles, leading to drooping of the eyelids and other issues.

Exposure keratitis is a condition where the cornea of the eye dries out due to insufficient tear production or inability to close the eyelid. This can happen when the facial nerve is damaged.

Ectropion occurs when the lower eyelid turns outward, leaving the eye exposed and vulnerable to dryness and irritation. This can happen due to facial nerve damage.

The nasalis muscle is located on both sides of the nose and helps with the movements of the nose and surrounding skin. It plays a role in breathing and facial expressions.

The alar part of the nasalis muscle is responsible for pulling the nostrils open, allowing for a wider intake of air. This action is important for strong breathing.

The transverse part of the nasalis muscle helps to wrinkle the skin on the bridge of the nose. This is visible during facial expressions like frowning and anger.

The nasal group muscles are important for the movement of the nose, facial expressions, and breathing.

The orbital muscles are the only muscles that can close the eyelids. Damage to the facial nerve can cause paralysis of these muscles, leading to an inability to close the eye, dryness, and other complications.

The Risorius muscle is a thin, paired muscle that extends the angle of the mouth laterally. It is responsible for the "smiling" expression and is often referred to as the "laughing muscle".

The Levator Anguli Oris muscle is a strap-like muscle that elevates the angle of the mouth, resulting in a smile-like expression.

The Zygomaticus Major muscle is a thin, paired facial muscle that elevates and everts the angle of the mouth. It contributes to the "laughing" expression along with the Risorius.

The modiolus is a dense, fibrous part of the face where many facial muscles converge. It plays a crucial role in controlling lip movement and expression.

The Buccal branch of the facial nerve is responsible for innervating several facial muscles, including some that control the mouth, cheeks, and lips.

The facial artery supplies blood to numerous facial structures, including the muscles around the mouth.

The muscles of the mouth are responsible for a variety of expressions and movements, including smiling, frowning, and speaking.

A small, triangular muscle located between the eyebrows (glabella). It originates from the nasal bone and lateral nasal cartilage and inserts into the skin of the glabella and the frontal belly of the occipitofrontalis muscle.

A muscle above the central incisor that inserts into the cartilaginous nasal septum. It works with the alar part of the nasalis muscle to pull the nose downwards, widening the nasal openings.

The muscle responsible for raising your eyebrows, causing an expression of surprise.

The muscle at the back of your head that helps move your scalp. It originates from the superior nuchal line and inserts into the epicranial aponeurosis.

A thick fibrous sheath that connects the frontal and occipital bellies of the Occipitofrontalis muscle.

The facial nerve (CN VII) innervates the Procerus muscle, responsible for frowning.

The facial artery (CN VII)'s angular and lateral nasal branches supply blood to the Procerus muscle.

The facial nerve (CN VII) innervates the Depressor Septi Nasi muscle, which pulls the nose downwards.

The frontal belly of the occipitofrontalis muscle, located on the forehead, raises the eyebrows and wrinkles the skin, creating a surprised or concerned expression.

The occipital belly of the occipitofrontalis muscle, located at the back of the head, pulls the scalp backward, creating a relaxed or 'thinking' expression.

The platysma muscle is a large, sheet-like muscle that covers the front of the neck. It helps to depress the mandible and angle of the mouth, creating a tense or strained expression.

The auricularis anterior muscle is a small muscle located in front of the ear. It helps to pull the ear forward and upward.

The auricularis posterior muscle lies behind the ear and helps pull the ear backward.

The auricularis superior muscle is located above the ear and helps pull the ear upward.

The muscles of the auricle, including the auricularis anterior, posterior, and superior, are responsible for moving the ear, although their function is minimal in humans.

The temporal branches of the facial nerve (CN VII) innervate the frontal belly of the occipitofrontalis muscle, enabling it to contract and move the forehead skin.
