MUSCLES OF THE TONGUE

Question 1

1. genioglossus

Answer 1

A. shape and position= fan-shaped muscle, constitutes bulk of tongue

B. MA= bilateral activity depresses the tongue especially central part, creating a longitudinal furrow, posteriror part pulls tongue anteriorly for protrusion

Question 2

2. hyoglossus

Answer 2

1. thin quadrilateral muscle

2. helps shorten the tongue, depresses the tongue

Question 3

3. styloglossus

Answer 3

1. small short triangular muscle

2. retrudes tongue and curls its sides working with genioglossus to form a central trough during swallowing

Question 4

4. palatoglossus

Answer 4

1. narrow crescent shaped palatine muscle forms posterior column of isthmus of fauces
2. elevate posterior tongue, depress soft palate, constrict isthmus of fauces

Question 5

1. superior longitudinal

Answer 5

1. thin layer deep to mucous membrane of dorsum

2. curls tongue longitudinally upward, elevated apex and sides of tongue, shortens/retrudes tongue

Question 6

inferior longitudinal

Answer 6

1. Narrow band close to
   inferior surface
2. Curls tongue longitudinally downward, depressing apex; shortens
   (retrudes) tongue

Question 7

transverse

Answer 7

1. Deep to superior longitudinal muscle
2. Narrows and elongates (protrudes)
   tonguec

Question 8

vertical

Answer 8

1. fibers intersect transverse muscle

2. Flattens and broadens tongue
