the superficial cervical fascia is AKA? what does it invest?
the investing fascia that invests the sternocleidomastoid and the trapezius
the vagus nerve is located where in the carotid sheath?
posterior aspect between the carotid and the internal jugular
where in the neck is the location of the buccopharyngeal fascia and the alar fascia?
buccopharyngeal (a continuation of the pretracheal) connects the posterior aspect of the thyroid gland and lines the posterior aspect of the esophagus. The alar fascia connects the two carotid sheaths and is found between the buccopharyngeal fascia and the prevertebral fascia.
the stylopharyngeus runs from the styloid process and travels between what two muscles? what innervates it? what is its action?
it runs between the superior and middle pharyngeal constrictors. Innervated by glossopharyngeal. It raises the larynx and pharynx and facilitates swallowing.
the styloglossus originates from the styloid foramen and travels where? what innervates it? what is its action?
travels to the posterior aspect of the tongue. It is innervated by hypoglossal nerve. Together they retract the tongue. It also pulls up side of tongue to create a trough for swallowing.
the stylohyoid is innervated by what nerve?
the facial
1. nasopharynx
2. oropharynx
3. laryngopharynx
4. aryepiglottic fold
5. epiglottic cartilage
6. palato-pharyngeal arch
7. salpingo pharyngeal fold
8. auditory tube
9. soft palate
label
what is the main action of the pharyngeal muscles and what nerve innervates them?
they constrict to move the bolus of food down. Vagus is the innervation
what is origination, innervation, and action of the levator velli palatini?
from the auditroy tube area, vagus nerve, and elevates the soft palate to prevent food from going into the nasal pharynx
location, action, and innervation of the salpingopharyngeus?
originates from the lateral part of the auditory tube and blends inferiorly with the palatopharyngeus. It draws the nasopharynx superiorly. Innervated by vagus
general location, innervation, and action of the palatopharyngeus?
lateral to the uvula. Vagus nerve. pulls pharynx and larynx up and toward the uvula when swallowing
general location, innervation, and action of the stylopharyngeus?
between styloid process and the pharynx. glossopharyngeal nerve. elevates pharynx and larynx and used in swallowing.
the pterygomandibular raphe is located between what two muscles?
the superior pharyngeal constrictor and the buccinator
general location, innervation, and action of tensor veli palatini?
lateral to the levator veli palatini in between the pterygoid plates. Trigeminal (mandibular nerve). Tenses the soft palate.
what nerve provides autonomics to the mucous glands lining he pharynx?
the vagus
what nerve provides sensory information to the pharynx?
glossopharyngeal
what arteries supply the pharynx (give parent branches as well)?
internal pharyngeal from superior thyroid, ascending pharyngeal from the external carotid, and the pharyngeal branches of the facial and lingual arteries
what are the two recesses associated with the larynx and their positions?
the vallecula posteriorly and piriform recess anteriorly.
what does the epiglottis do during swallowing?
it covers the glottis during folding to prevent food from going into the trachea.
1. superior horn of thyroid cartilage
2. thyroid cartilage
3. inferior horn of thyroid cartilage
4. cricothyroid ligament
5. trachea
6. cricoid cartillage
7. ghost image of arytenoid cartilage
8. thyrohyoid membrane
9. epiglottis
label
why are the tracheal cartilage rings C shaped instead of the complete circle?
for swallowing so the bolus from the esophagus can protrude into the trachea a bit.
what aspect of the cricoid cartilage is thicker?
the posterior aspect
1. arytenoid cartilage
2. muscular process
3. vocal process
4. cricoid cartilage
label
what is the general location, innervation, and action of the cricothyroid muscle?
it has 2 heads, the vertical (medial) and oblique (lateral) that arise from the lateral aspect of the thyroid cartilage and insert into the anterior aspect of the cricoid cartilage. The external laryngeal provides motor innervation while the recurrent laryngeal provides sensory info. It tenses the vocal cord to make high pitch noises.
general location, innervation, and action of the transverse arytenoid muscle?
inferior to aryepigglotic fold and superior to the posterior cricoid cartilage. innervated by the recurrent laryngeal nerve and it adducts the vocal cord to close the glottis between breaths.
what is the general location, innervation, and action of the posterior cricoarytenoid muscle?
on the posterior aspect of the cricoid cartilage. innervated by the recurrent laryngeal nerve. It abducts the vocal cord to open th glottis for breathing.
general location, innervation, and action of the lateral cricoarytenoid muscle?
supero lateral aspect of cricoid cartilage deep to the thyroid cartilage. It is innervated by the recurrent laryngeal and it adducts the vocal cord to close the glottis.
general location, innervation, and action of the thyroarytenoid muscle?
connects the arytenoid cartilage to the anterior aspect of the thyroid cartilage at the level of the vocal cord. innervated by recurrent laryngeal branch and it shortens the vocal cords for low pitch.
the internal laryngeal branch of the superior laryngeal provides what?
sensory info to the larynx above the vocal cord
the recurrent laryngeal nerve provides what?
sensory to the larynx below the vocal fold and motor to all intrinsic muscles of the larynx except the cricothyroid
what nerve passes through a hole in the thyrohyoid membrane?
the internal laryngeal nerve
