Clinical Correlates Flashcards
Cerebral aqueduct blockage
Hydrocephalus. Carries fluid from the third ventricle to the fourth ventricle.
Central canal blockage
Hydrocephalus. Carries fluid from 4th ventricle to spinal cord.
Lateral and medial apertures of 4th ventricle
allows CSF to leave ventricular system and enter subarachnoid space
Interventricular foramina blockage
passages from lateral ventricles that allow CSF to enter 3rd ventricle
Grey matter heterotropia
error in neuronal migration, ectopic cortical (grey matter) appraise in white matter. production of seizure disorders
Blood in spinal tap
CSF in subarachnoid space; aneurysm and closed head injury
superior cerebellar artery
oculomotor nerve
Cavernous sinus thrombosis
lateral to the body of the sphenoid bone. all cranial nerves and vessels that pass out of the skull at the superior orbital fissure pass through. oculomotor, trochlear, ophthalmic division of V.
occipital artery
medial and parallel to the attachment of posterior belly of digastric muscle
superficial to internal carotid and CN IX-CNXI
posterior auricular
posteriorly between the external acoustic meatus and the mastoid process of the temporal bone
superior thyroid artery
anteroinferiorly deep to the infrahyoid muscles to thyroid gland
SCM, thyroid, and infrahyoid muscles
superior laryngeal artery
superior laryngeal artery
runs with internal superior laryngeal nerve pierces the thyrohyoid membrane
lingual artery
deep to CN XII, stylohyoid, and posterior belly of digastric, deep to hyoglossus muscle
facial artery
superiorly ascends, posterior to digastric and stylohyoid muscles ant the angle of the mandible
deep grove in submandibular gland
submental artery to the floor of the mouth
hooks around middle of the inferior border of the mandbile to enter face
