Platysma                              Fascia covering superior part of pectoralis major and deltoid Edge of mandible, 
skin of lower part 
of face               
Assists in depressing mandible and tightens the fascia of neck depresses lower lip.

Anterior- first ribMiddle- first rib

Posterior- second rib

Bilaterally – elevate ribs during inhalationUnilaterally- with rib fixed, laterally flexes the neck, rotates head and neck to opposite side

Anterior- flexes the neck

Brachial plexus and subclavian artery pass between the middle and anterior scalene.
Longissumus Capitis C3-C6 transverse processses Base of occipital bone Flexion of head

temporal bone and 
superior nuchal 
line of occiput
Bilaterally- extends neck and headUnilaterally- rotates the head to the same side Palpate between trapezius and SCM above levator scapula.Wrap around deeper neck muscles.

of mandibular 
condyle and
capsule of
mandibular joint
Protrudes mandible, pulls articular disc forward, assists in rotary motion while chewing. Active in TMJ, tooth grinding and headaches
