  • Front
  • Back
Epicranius- Frontal & occipital bellies
facial. with aponeurois fixed, frontal belly raises eyebrows; occipital belly fixes aponeurosis and pulls scalp posteriorly
Oribcularis oculi
facial, various parts can be activated individually; closes eyes, produces blinking, squinting, and draws eyebrows inferiorly
Levator Labii Superious
Facial, raises and furrows upper lip; opens lips
Zygomaticus
Facial, raises lateral corners of mouth upward (smiling muscle)
Risorius
facial, draws corner of lip laterally; tenses lip; zygomaticus synergist
depressor labii Inferious
Facial, draws lower lip inferiorly
orbicularis Oris
facial, closes mouth; purses & proreudes lips (kissing & whistling muscle)
mentalis
Facial, Protrudes lower lip; wrinkles chin
Buccinator
Facial, Draws corner of mouth & mastication, laterally; compresses cheek (as in whistling); holds food between theeth during chewing
Masster
Mastication, closes jaw & elevates mandible
Temporalis
mastication, closes jaw; elevates and retracts mandible
Platysma
Sopuerficial, depresses mandible; pulls lower lip back and down( produces downward sag in mouth)
Sternocleidomastoid
Superficial, Stimulates contraction of both muscles of pair causes flexion on neck forward, generally against resistance; acting independently, rotate head and shoulder on opposite side
Pectoralis major
thorax & shoulder, superficail, prime mover of the armflexion; adducts, medially rotates arm. with arm fixed, pulls chest upward
serratus anterior
thorax & shoulder, superficial, moves scapula forward toward chest wall; rotates scapula, causing inferios angle to move laterally & upward; abduction & raising of arm
Deltoid
thorax & shoulder superficial, Acting as a whole of arm abduction; when only specific fibers are active, can ain in flexion, extenshion, and rotation of humerous
Pectoralis minor
thorax & shoulder superficial, with ribs fixed, draws scapula forward and inferiorly; with scapula fixed, draws rib cage superiorly
External intercostals
thorax deep muscle, pulls ribs toward one another to elevate rib cage, aids in inspiration
internal intercostals
thorax deep tissue, draws ribs together to depress rib cage; aids in forced expiration; antagonistics to external intercostals
diaphragm
thorax deep muscle, prime mover if inspiration flattens on contraction, increasing vertical dimensons of thorax; increases intraabdominal pressure
rectus abdominis
abdominal wall, flexes and rotates vertebral column; increases abdominal pressure ; fixes and depresses ribs, stabilizes pelvis during walking; used in sil-ups and curls
external oblique
abdominal wall, aids muscles of back in trunk rotation and lateral flexion; used in oblique curls
internal obique
as for external oblique
transversus abdominis
compresses abdominal contents
trapezius
neck shoulder & trunk, extends head, raises rotates and retracts scapula and stabilizes it; superior fibers elevate scapula (as in shruging shoulders); inferiou fibers depress it
latissimus dorsi
neck shoulder& trunk, prime mover of arm extension, adducts and medially rotates arm; depresses scapula brings arm down in power stroke, as in striking a blow
infraspinatus
shoulder neck & trunk, lateral rotaion of humerous; helps hold head of humerous in glenoid cavity, stabilizes shoulder
teres minor
shoulder neck & trunk, lateral rotaion of humerous; helps hold head of humerous in glenoid cavity, stabilizes shoulder
teres major
neck shoulder trunk, extends, medially rotates, and adducts humerus; synergist of latissimus dorsi
supraspinatus
neck shoulder trunk, assists abduction of humerous; stabilizes shoulder joint
levator scapulae
neck shoulder trunk, elevates and adducts scapula; with fixed scapula, flexes neck to the same side
phomboids- major and minor
neck shoulder trunk, pulls scapula medially ; stabilizes scapula; rotates glenoid cavity downward
Quadratus lumborum
veretrabral column, each flexes vertebral column laterally; together extend the lumbar spine and fix fib 12; maintains upright posture
triceps brachii
humerous, powerful forearm extensor; antagonist of forearm flexors
anconeus
humerous, abducts ulna during forearm pronation; extends elbow
biceps brachii
humerous, flexion of elbow and supination of forearm, "it turns the corkscrew and pulls the cork", weak arm flexor
brachioradialis
humerous, synergist in forearm flexion
Brachialis
humerous, a major flexor of forearm
pronator teres
anterior compartment, acts synergistically with pronator quadratns to pronate forearm; weak elbow flexor
flexor caroi radialis
anterior compartment, powerful flexor of wrist, abducts hand
palmaris longus
anterior compartment, flexes wrist; tenses skin and fascia of palm
Flexor carpi ulnaris
humerous, powerful flexor of wrist; adducts hand
flexor digitorum
humerous, flexes wrist and middle phalanges of fingers 2-5
flexor pollicis longus
deep humerous, flexes thumb
flexor digittorum profundus
deep humerous, sole muscle that flexes distal phalanges; assis in wrist flexion
Extensor carpi radialis longus
hand & fingers posterior superficial, extends & abducts wrist
Extensor carpi radialis brevis
hand & fingers posterior superficial, extends & abducts wrist; steadies wrist during finger flexion
extensor digitorum
hand & finger posterior superficial, prime mover of finger extension; extends wrist; can flare fingers
