superior this is a laryngoscopic view
where is the larynx
top of trachea
what tracts is the larynx between
upper and lower respiratory tract
what does the larynx do being between the upper and lower respiratory tract
controls passage of the 2 tracts
what are the 2 supportive frameworks
cricotracheal membrane and hyoid bone
cricotracheal membrane
job of cricotracheal membrane
secures larynx to top of trachea
hyoid bone
characteristics of hyoid bone
U shaped above larynx attaches via membrane and ligaments
what is special about the hyoid bone
it is the only bone in the body not attached to another bone its in a muscular sling
what are the different directions that the hyoid bone can be pulled in
forward and up back and down downward pulls larynx w it
what other things are the hyoid bone involved in
tongue and mandible mvmt
what framework is this
cartilaginous framework
