Anatomy Flashcards
Branch of Superior Laryngeal nerve of Vagus that supplies Cricothyroid muscles
EXTERNAL Laryngeal nerve
Provides sensory ABOVE the vocal cords
INTERNAL Laryngeal nerve
- Brance of Superior Laryngeal nerve of vagus
- other branch: EXTERNAL laryngeal nerve which is the motor supply of cricothyroid muscles
Sensory below the vocal chords and motor to muscles of phonation except cricothyroid muscle
Inferior or Recurrent Laryngeal nerve
The Right Recurrent(Inferior) laryngeal nerve hooks around which structurr
Right Subclavian artery
the Recurrent or inferior laryngeal nerve provides motor supply to muscles of phonation except the cricothyroid muscle which is supplied by external branch of superior laryngeal nerve.
Suprahyoid muscles that is supplied by NERVE TO MYLOHYOID
Anterior belly of Digastrics
Mylohyoid
Suprahyoid muscles that is supplied by FIRST CERVICAL NERVE
Geniohyoid
Suprahyoid muscles that is supplied by FACIAL NERVE
Posterior belly of digastric
Stylohyoid
SUPRAHYOID muscles
action: elevates hyoid bone
digastric
Stylohyoid
Mylohyoid
Geniohyoid
Infrahyoid muscles
Deep group:
- Thyrohyoid
- Sternothyroid
Superficial group:
- Omohyoid
- Sternohyoid
Only Infrahyoid muscles that is not attached to the hyoid bone
Sternothyroid
Only Infrahyoid muscle supplied by the 1st cervical nerve
Thyrohyoid
-Elevates the larynx
Infrahyoid muscle that depresses the larynx
sternothyroid
-supplied by ansa cervicalis (C1,C2,C3)
Spread of infection frim a dental abscess can spread to the mediastinum by which path
Retropharyngeal space
Ludwig’s angina involved what space
Submandibular space
Only bone that does not articulate with another bone
Hyoid bone
-At the level of C3
