Review Sessions 1-4 Flashcards
Which embryological structure do the muscles of mastication develop from
1st pharyngeal arch
What is the main action of corrugator supercilii
Draw eyebrows together
What is posterior auricular nerve
Branch of the facial Nerve
Arises just after it exits the stylomastoid foramen, runs up to supply muscle behind ear and occipitalis muscle
Pre tracheal fascia surrounds
Thyroid gland, oesophagus and pharynx, trachea and larynx
Pre tracheal fascia does not surround
SCM, as this is within deep investing layer (splits to surround SCM and trapezius)
Which examinations are indicated in a patient with Virchow’s node swelling
Abdominal and testicular Examination
A patient presents with a lateral neck lump that is pulsating, bruit is heard. Most likely diagnosis?
Carotid artery paraganglioma
(tumour of carotid artery wall)
A patient presents with a medial neck lump that is pulsating, bruit is heard. Most likely diagnosis?
Thyroid artery aneurysm
What is E and A
E is Superficial temporal artery
A is facial
The pre tracheal and buccopharyngeal fascia does not envelope
SCM and Suprahyoid muscles
Carotid sheath extends from and to
From base of skull inferiorly to the aortic arch
Is the Opthalmic or occipital artery a branch of the external carotid
Occipital
Weird branch not in pneumonic that arises from facial nerve
Posterior auricular
Is maxillary or mandibular a branch of facial nerve

Lesser wings of sphenoid
oculomotor nerve passes through
Optic canal
Opthalmic vein and artery and trochlear nerve transmit through the
Superior orbital fissure

Petrous part of temporal bone
What is blue box
Lesser wing of left sphenoid
What is G
Carotid canal
Which dural venous sinus is found within the middle cranial fossa
Cavernous sinus
which sinuses lie in posterior cranial fossa
Transverse and sigmoid
Petrosal sinus lies in
Posterior cranial fossa
What are A and B
Superior sagittal sinus
Falx cerebri
What is the most likely source of blood
