Physiology –Muscles Table







Runs vertically on forehead, originates in tissue on scalp

Composed of medial & lateral parts

Draws eyebrows & skin upward




Elevates lips

Orbicularis Oris




Schimeter muscles around mouth

Mucous membrane, muscles inserting into lips

Closes lips

Obicularis Oculi

Around eyes

Outer: Medial orbit


Palpebral: Palpebal ligament

Three parts: Orbitial, Palpebral, & lacrimal

Projecting and moistening eyes, expressive displays, constrict skin, reduces opening, closes the eye


Major: Cheek bone (near mouth corner)


Minor: Lateral part of cheek

Inverted by zygomatic & buccal branches

Lifts corner of mouth upward (smiling


Draws skin of lip upward laterally

Levator Labii Superioris

Upper lip & cheek

Two parts: Nasal & lateral

Nasal: Originates near/on cheek bone


Lateral: From medial part of orbit

Raises upper lip straight up

Raises upper lip, stretched nasal wing up, & wrinkles nose

Depressor Labii Inferioris

Originates in chin part & inserts into skin of lower lip

Inverted by mandibular & buccal branches of facial nerve

Pulls red parts of lips (lower) straight down & skin of lower lip laterally down


Part of mandible below the front teeth

Associated by mandibular & buccal branches of facial nerve

Pushes chin boss upward



Maxilla & mandible (inserts into)

Maintains cheeks near teeth & food in position for chewing


From upper chest through neck to lower cheek

Innverted by deep cervical branch of facial nerve

Assists in depressing mandible & tightens the fascia of neck


Lowers jaw and lip




Manubrium of sternum

Inserts into mastoid process of temporal bone

Lateral flexion to same side & rotation to opposite sides


Flexion of head & neck

Pectoralis Major

Sternum to 7th rib

Inserts to crest of greater tubercle of humerus

Flexion of humerus, extension of humerus returning from flexion

Pectoralis Minor

3rd, 4th, & 5th ribs

Inserts into caracoid process of scapula

Tilts scapula forward, depresses & abducts scapula


Lateral 1/3 of clavicle

Inserts into deltoid tuberousity

Abducts the shoulder joint

Serratus Anterior

Scapula fossa of scapula

Inserts into lesser tubercle of humerus

Medially rotates shoulder joint


Originated at the inner surface of the scapula

Inserts into inferios lateral aspect of clavicle

Elevates first rib, stabilizes sternoclavicular joint



Rectus abdominus

Front of lower torso

This bands of connective tissue

Flex the spine

Transverse Abdominus

Deepest muscle to the core wrap under abs

Acts as a natural weight belt

Essential for trunk stability as well as keeps stomach tight

Internal Obliques

Flank rectus abs/ run diagonally no body allowing for angles movement

Runs opposite of internal

Twisting of torso


Rotate torso & stabilizes abs

External Obliques

Each side of rectus/ run diagonally on body allowing for angled movement

Runs opposite of external

Twisting/ Rotate torso & stabilizes abs


Runs down upper section of spinal cord

Long, trapezoid shape

Scapular elevation

Latisimus Dorsi

From side of body toward spinal area


Attached to the upper humerus to vertebral

Largest in back


Fan shaped

Pulls arm toward pelvis
