25
how many laryngeal cartilages
9 | name them
26
thyrohyoid membrane
extrinsic ligament pierced by internal laryngeal nerve and superior laryngeal artery
27
intrinsic ligaments
quadrangular ligament cricovocal ligament convert larynx to tube
28
quadrangular ligament
anterior to epiglottic and thyroid posterior to arytenoid more superior forms vestibular ligaments and aryepiglottic ligaments -covered with mucosa
29
cricovocal ligament
aka conus elasticus cricoid to thyroid and artyenoid inferior thickened: - median cricothyroid - lateral cricothyroid - vocal ligament
30
cuneiform and corniculate
help maintain inlet
31
false vocal cord
quadrangular
32
true vocal cord
cricovocal ligament
33
vocal folds
from mucosa overlying vocal ligament and vocalis muscle
34
laryngeal ventricle
between vestibular and vocal folds | -area of weakness
35
joints of larynx
cricothyroid and cricoarthenoid joints
36
cricothyroid ligament
cricoid - to inferior horn thyroid -synovial gliding thyroid moves on cricoid change vocal cord length
37
cricoarythenoid joint
cricoid - to arytenoid -synovial gliding and rotate -arytenoid rotation, glide one another
38
when we speak
vocal folds adduct
39
motion of laryngeal cartilages
rotation arytenoid -abduct/adduct gliding close rima glottitis -adduct rotating thyroid -increase/decrease tension vocal ligaments
40
cricothyroid
unique because its from arch 4** all others arch 6 innervation changes
41
action of cricothyroid
tilt thyroid forward to elongate and tighten vocal ligaments
42
action of transverse and oblique artyenoid muscles
adduct cartilages | -close laryngeal inlet
43
innervation of cricothyroid
external laryngeal branch of superior laryngeal nerve | -only one not innervated by recurrent laryngeal nerve
44
innervation of most larynx
recurrent laryngeal nerve
45
action of posterior cricoarytenoid muscle
abduct vocal fold | -open rima glottidis
46
action of lateral cricoarytenoid muscle
adduct vocal fold | -close rima glottidis
47
action of thyroarytenoid muscle
rotates thyroid cartilage back to shorten and loosen vocal ligament opposition to cricothyroid
48
action of vocalis muscle
local control of vocal ligament -minute adjustments innermost portion of thyroarytenoid muscle
49
internal laryngeal nerve
pierces thyrohyoid membrane - GVE-P and GVA proximal to true vocal folds - SVA to epiglottic region (taste)
50
cough reflex
superior laryngeal nerve stimulation - GVA causes conraction of laryngeal muscles vagus - stimulates cough to force air out
51
cough afferent and efferent
afferent CN X | efferent CN X
52
superior laryngeal nerve lesion
loss of cough reflex cricothyroid m paralysis - monotonous voice
53
heimlich maneuver
increase intrathoracic pressure | dislodge object
54
superior laryngeal nerve block
with endotracheal tube - between hyoid and superior border of thyroid - pierces thyrohyoid membrane and anesthetic to superior laryngeal nerve
55
external laryngeal nerve
SVE to cricothyroid muscle
56
superior laryngeal nerve
CN X internal laryngeal nerve external laryngeal nerve
57
inferior laryngeal nerve
CN X continuation of recurrent -passes inferior to inferior constrictor muscle GVE-P and VGA distal to vocal folds SVE to all muscles of larynx, except cricothyroid
58
infraglottic region innervation
inferior laryngeal nerve
59
supraglottic region innervation
internal laryngeal nerve from superior laryngeal nerve
60
muscles of larynx innervation**
inferior laryngeal nerve except cricothyroid - external laryngeal nerve from superior laryngeal nerve**
61
injury to recurrent laryngeal nerve
bilateral - take away voice | unilateral - hoarse voice
62
blood supply above vocal folds
superior laryngeal artery
63
superior laryngeal artery
branch of laryngeal artery | -pierces thyrohyoid membrane
64
blood supply below vocal folds
inferior laryngeal nerve
65
inferior laryngeal artery
branch of inferior thyroid artery
66
cricothyroid artery
to cricothyroid muscle | -branch of superior thyroid artery
67
lymph drainage
supraglottic - superior deep cervical lymph nodes infraglottic - inferior deep cervical lymph nodes
