Cricoid cartilage
Pharynx
The esophagus descends in the ________ behind the __________ and ends opposite the body of the _____ cervical vertebra
Midline
Trachea
6th
Anterior to the esophagus
trachea and
recurrent laryngeal nerve
Posterior to the esophagus
prevertebral muscles
and vertebral column
Lateral to the esophagus
thyroid gland,
carotid sheath,
thoracic duct on the left side
Blood supply of the esophagus
Inf thyroid arteries
Lymphatic drainage of the esophagus
Deep cervical lymph nodes
Nerve supply of the esophagus
recurrent laryngeal nerve and
branches from sympathetic trunk
Sphincter responsible for voice production
Larynx
The larynx opens above into the ____________ and continuous with the _______ below
Laryngopharynx
Trachea
Cartilages of the larynx
Thyroid
Cricoid
Cuneiform
Corniculate
largest and consist of two laminae, each of which has a superior cornu and an inferior cornu;
on the outer surface is an oblique line for attachment of muscles
Thyroid cartilage
has a shallow arch in front & a broad lamina behind;
lies below the thyroid cartilage and articulates with the inferior cornu;
posteriorly, lamina articulates on its upper edge with the arytenoid cartilages
Cricoid cartilage
two in number and conical in shape; articulates with the arytenoid cartilages
Corniculate cartilages
rod-shaped; strengthens the aryepiglottic folds
Cuneiform cartilages
leaf-shaped and lies behind the root of the tongue; attached by its stalk to the thyroid cartilage
Epiglottis
connects the upper margin of the thyroid cartilage to the hyoid bone
Thyrohyoid membrane
The thyrohyoid membrane is pierced by the
Superior laryngeal vessels and the internal laryngeal nerve
extends between the epiglottis and the arytenoid cartilage
Quadrangular membrane
The inferior margins of the quadrangular membrane forms the
vestibular ligaments which forms the interior of the vestibular folds
attached below to the upper margin of the cricoid cartilage; ascends on the medial surface of the cartilage instead of being attached to the lower margin of the thyroid cartilage
Cricothyroid ligament
The upper margin of the coricothyroid ligament forms the
vocal ligament on each side
anterior end of each vocal ligament is attached to the ___________; the posterior end is attached to the
Thyroid cartilage
vocal process of the arytenoid cartilage
muscular tube extending from pharynx to stomach
Esophagus
