  - - - jaw super out
    - - jaw noy super out but in
  - - - palm faces up
    - - palm faces down
- - - - plays role in maintaining normal body temperature
- - - - thick multipennate muscle; prime mover of arm abduction when all its fibers contact simultaneously
    - - large fleshy muscle; powerful forearm extensor
    - - 2 headed fusiform muscle; flexes and supinates forearm
    - - strong muscle that is immediately deep to biceps brachii; a major forearm flexor
    - - superficial muscle of lateral forearm; synergist in flexing forearm
    - - runs diagonally across forearm; strong flexor of hand
    - - most medial muscle of this group; strong flexor and adductor of hand
    - - parallels brachioradialis on lateral forearm; extends hand
    - - lies medial to extensor carpi radialis brevis; prime mover of finger extension
  - - - superficial muscle of anterior thigh; extends leg and flexes thigh at the hip
    - - found at groin; helps with hip adduction and knee flexion
    - - largest head of the group; extends leg and stabilizes knee
    - - forms inferomedial aspect of thigh; extends knee
    - - superficial lateral muscle overlies fibula; plantar flexes and everts foot
    - - unipennate muscle on anterolateral surface of leg; prime mover of toe extension
    - - superficial muscle of anterior leg; prime mover of dorsiflexion
    - - superficial muscle of pair; plantar flexes foot
    - - broad, flat muscle, deep to gastrocnemius; plantar flexes foot
    - - most lateral muscle of the group; extends thigh and flexes leg
    - - deep to semitendinosus; extends thigh and flexes leg
    - - hip
    - - overlies middle aspect of adductor magnus; adducts, flexes, and medially rotates thigh
    - - straplike superficial muscle; flexes, adducts, laterally rotates thigh
  - - - major back muscle; responsible for rotating and stabilizing the scapula
    - - cover superior portion of chest; adducts and medially rotates arm
    - - the abs area; most superficial muscle pair; extend pubis to rib cage; flex and rotate lumbar region of vertebral column
    - - largest and superficial of three lateral muscles; flex vertebral column and compress abdominal wall
    - - broad, flat, triangular muscle on lower back; lumbar region; prime mover of arm extension; powerful arm adductor; medially rotates arm
    - - partially covered by deltoid & trapezius; rotates arm medially
    - - thick, rounded muscle; extends medially rotates and adducts arm
  - - - prime mover of jaw; around mandible; jawline area
    - - fan shaped muscle; head
    - - the mouth area; before the masseter
    - - deep in platysma; flexes and laterally rotates head
    - - around neck, plays a role with facial expressions; can make lower lip go down
- - - - are longest muscle cells, and have striations
  - - - striated cells
      - not voluntary
  - - - ex: stomach, urinary bladder, respiratory passages
    - - consists of elongated cells but no striations
    - - they're slow and sustained
