head and neck Flashcards
correct statement about papillae;
fungiform papillae are innervated by (chorda timpany)facial nerve
filiform papillae are innervated by (chorda tympany)facial nerve
vallat papillae by glossopharyngeal nerve
common sensation and mucos membrane of tongue is innervated by lingual nerve (branch of mandibular nerve) for anterior of sulcus terminalis and glossopharungeal and vagus for posterior of sulcus terminalis
all of these pass through supraorbital fissure
superior and inferior opthalmic vein
oculomotor nerve
trochlear nerve
abducent nerve
ophtalmic nerve
lateropharyngeal space contain:
glossopharyngeal nerve
vagus nerve
abducent nerve
hyoglossal nerve
internal jugular vein
internal carotid artery
deep cervical lymph nodes
asseccory nerve
if a patient is unable to adduct the vocal fold the following muscles are paralized:
lateral crycothyroid muscle
retropharyngeal space contain:
loose connective tissue
lumph nodule
all muscles mentioned are involed in opening of mouth
mylohyoid
anterior digasteric
geniohyoid
lateral ptrygoid
maxillary artery supply supplie:
it passes through ptrygopalatine fossa
it supply thevlower teeth
it terminate part is sphenopalatine artery
it does not supply the toung
following cranial nerve contain only motor fibers:
oculumotor
trochlear
abducent
accessory
hypoglossal
posterior ethmoidal sinus opens to superior nasal meatus
inferior nasal meatus recieve nasolacrimal duct
maxillary and middle ethmoidal sinus opens to semilunar hiatus
the frontal and anterior ethmoidal sinus opens to infundiulum
ligaments connect axis and occipital bone:
tectoria membrane
alar and median apical ligament
sternucleido mastoid is attached superiorly to mastoid proccess
inferiorly to sternal head of clavicle
masseter;
its masticatory muscle
it is attached to the zygomatic arch
it is attached to the lateral surfaceof mandible ramus
facial artery:
it terminate as angular artery
its anterior to masseter
it joint dorsal nasal branch of opthalmic artery
vagus nerve:
`it leaves the skull through jugular foramen
in the head it is located in parotid region
it supply smooth muscle of esophagus
inferior ganglion concered with sensation with heart larynx lung and some neurones transmit impulses from taste ending in vallecula and epiglosis
parotid gland:
it contain external carotid artey which terminate there
it has facial nerve and retromandibular vein
it is innervated by glossopharyngeal nerve
it is placed lateral to retrostyloid space !
