Throat Anatomy & Physiology Flashcards
which nerve suppliesgeneral somatic afferentinnervation from the anterior two-thirds of the tongue?
mandibular nerve (CN V3)
which nerve supplies special sensation (taste) to the anterior 2/3 part of the tongue?
facial nerve (CN VII)
which nerve supplies general somatic afferentinnervation to the Posterior 1/3rd of the tongue?
glossopharyngeal nerve (CN IX)
which brachial arch forms the Anterior 2/3rd
of the tongue?
From 1st branchial arch
which brachial arch forms the Posterior 1/3rd
of the tongue?
From 3rd branchial arch
which papillae do not contain taste buds?
Filliform papillae
what is the epithelium of the Oropharynx?
Stratified, non-keratinised squamous
what is the nerve supply of the Oropharynx and Hypopharynx?
Pharyngeal plexus- CN IX & X
what is the myenteric plexus?
major nerve supply to the gastrointestinal tract and controls GI tract motility
which muscles regulate the movement of the entire laryngeal complex?
Extrinsic muscles (infrahyoid, suprahyoid)
which muscles regulate the movement of the vocal cords?
intrinsic muscles
all intrinsic muscles (except for cricothyroid) are motor innervated by which nerve?
recurrent laryngeal nerve
the cricothyroid is motor innervated by which nerve?
external laryngeal nerve
what is the sensory innervation of the supraglottic?
internal laryngeal nerve
what is the sensory innervation of the Glottic and subglottic?
recurrent laryngeal nerve
what does the pulmonary phase lead to in speech?
creates the energy flow with inflation and expulsion of air. This activity provides the larynx with a column of air for the laryngeal phase
what part does the laryngeal phase perform in speech?
vocal folds vibrate at certain frequencies to create sound that is then modified
which phase modifies the voice?
supraglottic/oral/nasal phase
which action forms words?
pharynx, tongue, lips, and teeth
