anteriorly

Question 32

When we talk about the Larynx and the Hyoid the mandible is

Answer 32

still - it is a different function for the muscles. If you talk about the mandible the Hyoid is still and the function of muscles relate to mandible e.g. elevate and depress

What are the functions of the Digastric posterior muscle - with reference to the movement of the Hyoid? (the mandible is still)

Answer 37

Posteriorly belly draws hyoid superiorly and posteriorly

Question 38

Answer 38

Controls the distance

Question 39

What are the 2 extrinsic laryngeal muscles
