(22 cards)
Bones of the neck
Hyoid bone, cervical vertebrae
Fascia of the Neck
Subcutaneous, Deep cervical, retropharyngeal space
What is within the subcutaneous fascia
platysma, fat
What is within the deep cervical fascia
investing layer, prevertebral layer, pretracheal layer
What is within the investing layer
splits around the SCM and Trapezius, surrounds the whole neck
What is within the prevertebral layer
muscles that move the vertebral column, wrapping bone, brachial plexus
What is within the pretracheal layer
inferior to hyoid, blends into the pericardium (carotid sheath)
What is within the Carotid sheath
internal jugular, common carotid, vagus, blended by alar fascia
