Q

Capsular ligament

A

Contains posterior, anterior, and lateral ceratocricoid?

Rotational/gliding motion dictated by capsular ligament places the vocal folds under increased tension, thus causing an increase in the pitch of the voice

Q

Hyoepiglottic ligament

A

Connecting between the hyoid bone and epiglottis

23
Q

Median and lateral glossoepiglottic ligaments

A

Connections b/t the tongue and epiglottis

24
Q

Valleculae

A

Small valleys seen between the epiglottis and the root of the tongue, great place for food to get caught

25
Cartilaginous glottis
Posterior 2/5 of the glottis, from vocal process to muscular process
26
Membranous glottis
3/5 total length of glottis and is the anterior 3/5 of vocal fold. Extends from thyroid cartilage at the angle (anterior commissure)
27
Sternothyroid muscle
Origin- posterior surface of the manubrium of the sternum and the first costal cartilage Insertion- oblique tendon or line of the thyroid cartilage Function- draws thyroid cartilage downward and can be involved in positioning
28
Thyrohyoid muscle
Origin- oblique tendon or line of the thyroid cartilage Insertion- lower border of the greater horn of the hyoid bone Function- reduces distance b/t thyroid cartilage and hyoid bone (initiation of swallow)
29
Digastric muscle
Pairs muscle with anterior & posterior bellies Origin: anterior from inside surface of lower border of mandible near symphysis, posterior is hyoid bone Insertion: lesser horn of the hyoid bone, posterior goes up to mastoid process Function: draws hyoid bone up and forward, if hyoid is fixed may depress lower jaw
30
``` Mylohyoid muscle (Long card...scroll down) ```
Origin: along the mylohyoid line along inner surface of mandible from man fibulae symphysis to last molar Insertion: medially down to opposite side tendinous raphe which extends from the mental symphysis to hyoid bone. Posterior fibers attach directly to hyoid bone Function: when contracted elevates hyoid bone, floor of mouth, and tongue * important for initial Stages of swallowing **thin unpaired sheet of muscle fibers which for floor of mouth
31
Geniohyoid muscle
Origin: come from a short tendon, from lower mental spine at mandibular symphysis Insertion: course backward and downward to insert on the anterior surface of the body of the hyoid bone Function: pulls hyoid bone up and forward *sits kind of on top of mylohyoid
32
Hyoglossus
Origin: upper border of the body and greater horns of hyoid Insertion: posterior and lateral regions of tongue Function: Influences the position of the larynx indirectly *extrinsic muscle of tongue
33
Genioglossus
Origin: mental symphysis of mandible Insertion: body of hyoid (lower fibers) and whole undersurface of tongue (upper fibers) Function: elevates hyoid bone and draws it forward *extrinsic muscle of tongue
34
Sternohyoid muscle
Origin: posterior surface of the manubrium of the sternum Insertion: fibers course vertically upward and insert on the lower border of the body of the hyoid bone Function: if sternum is fixed draws hyoid down, if hyoid is fixed raises sternum, potentially help if respiration
35
Omohyoid muscle
Origin: upper border of the scapula Insertion: inferior/lateral belly fibers course horizontally to an intermediate tendon and the. The superior belly runs vertically to insert into the greater Cornu of the hyoid bone Function: contraction depresses the hyoid bone *long, narrow two belly muscle on anterior lateral surface of the neck
36
Intrinsic muscles of the larynx
Involved in sound production and protection of airway. Also involved in swallowing(protection)
37
Vocal folds
Thyroarytenoid muscle and vocal ligament
38
Abductors and adductor a
Alter shape of glottis
39
Glottal tensors and relaxers
Tensors- elongate and tighten the vocal folds Relaxers- shortens folds Affect speed of vibration
40
Medial compression
The extent of force with which the vocal folds are brought together at the midline
41
Longitudinal tension
The degree of stretching force
42
Thyroarytenoid muscle
Very complex and is composed of two primary bundles referred to as the thyromuscularis and the thyrovocalis portions
43
Thyromuscularis
Origin: arises anteriorly from the lower half of the thyroid angle and courses Posteriorly Insertion: into the anterolateral surface and muscular process of the arytenoid cartilage Function: glottal relaxer
44
Thyrovocalis
Origin: posterior surface of the angle of the thyroid and courses Posteriorly Insertion: he vocal process and lateral surface of the arytenoid cartilages Function: vocal fold tensor *vocal ligament sits on the very edge of thyrovocalis
45
Posterior cricoarytenoid muscle
Origin:shallow depression on the posterior surface of the cricoid lamina Insertion: upward and lateral to converge on the posterior surface of the muscular process of the corresponding arytenoid cartilage Function: abduction of vocal folds (also lengthens vocal folds by the cricoarytenoid joint which pulls arytenoids back and up, fix arytenoids and rock thyroid cartilage forward *only abductor muscle of the larynx
46
Lateral cricoarytenoid *slide 110*
Origin: the upper border of the arch of the cricoid cartilage Insertion: courses upward and back and inserts into anterior surface of muscular process of corresponding arytenoid cartilage Function: ?
47
Interarytenoid muscle *slide 112*
An unpaired muscle located on the posterior surfaces of the arytenoid cartilages
48
Transverse arytenoid *slide 113*
Origin: lateral margin and posterior surface of one arytenoid Insertion: courses in a horizontal direction and inserts into lateral margin and posterior surface of the opposite arytenoid cartilage Function:?
49
Oblique arytenoids *slide 114*
Origin: posterior surface of the muscular process of one arytenoid Insertion: into Alex of the opposite cartilage, a few fibers angle upward and forward inserting into the lateral borders of the epiglottis Function:?
50
Cricothyroid muscle *slide 116*
Origin: anterior-lateral arch of cricoid cartilage Insertion: thyroid cartilage, two parts: Lower or oblique (pars oblique) insert in anterior margin of inferior Cornu of thyroid cartilage Upper of anterior (pars recta) insert along inner aspect of the lower margin of the thyroid laminae Function:?
