Transverse arytenoids
Where does the cricothyroid intrinsic laryngeal muscle lie
Between thyroid and cricoid carriages
Which intrinsic muscle tips the thyroid cartilage anterior and inferior which places tension in the vocal cords
Cricothyroid
Which intrinsic laryngeal muscles attach to the arytenoids and abduct the vocal cords to open the rima glottidis
Posterior cricoarytenoids
Which intrinsic laryngeal muscles connect the 2 arytenoid cartilages and adduction the vocal cords to close the Rima glottidis
Transverse arytenoids
Which nerve innervates the Cricothyroid muscle (intrinsic) and is sensory to the larynx above the vocal folds
Superior laryngeal (branch of vagus)
Which nerve innervates all intrinsic muscles EXCEPT Cricothyroid muscles and is sensory to the vocal folds

NaMe the 3 salivary glands which secrete saliva into oral cavity
Parotid
Submandibular
Sublingual
Submandibular and sublingual Saliva secretion is stimulated by parasympathetic/sympathetic fibres of the facial/laryngeal/accessory/glossopharyngeal nerve
Pick correct answer from slashed phrase
Parasympathetic
Facial
Parotid Saliva secretion is stimulated by parasympathetic/sympathetic fibres of the facial/laryngeal/accessory/glossopharyngeal nerve
Pick correct answer from slashed phr
Parasympathetic
Glossopharyngeal
Glandular secretion is secreted by ____ fibres
Parasympathetic

What could happen is the recurrent laryngeal nerve is damaged
In transit muscles of ipsilateral side don’t function and vocal cords on affected side cannot move
What could be a sign of laryngeal cancer
Voice hoarseness
Damage or disease of parotid gland risks damage i which nerve
Facial
Which saliva gland does mumps present on
Parotid
Explain why horseless of voice could indicate lung cancer
-Left Recurrent laryngeal nerve runs close the lungs and innervates all intrinsic muscle left side except Cricothyroid
-if intrinsic muscle in left are weak of Paul used the left vocal fold cannot move which effects voice
A patient develops weakness in R side face after surgery if right parotid, what happened
-Injured facial nerve since it runs close to parotid
-facial has 5 branches as it travels through parotid and individual injure results in facial weakness/ parylsis on ipsilateral side
After an endotracheal tube is passed through vocal cords bow can an anesthetiser be sure that the tip of the tube is in the trachea
-this tube is passed into trachea for ventilation
-a laryngoscope is used to visualise the vocal cords and the tube passing through them
-correct placement is confirmed CO2 (expired air) on machine and an auscultation of both lungs to make sure the tube is not in bronchi
