Nerves and Ligaments and Veins and Such Flashcards
Supraorbital notches
transmit supraorbital vessels and supraorbital nerve as the pass superiorly to the forehead region
Meningeal Grooves
for the middle meningeal arteries; supply blood to the dura mater
sagittal sulcus
lodges the superior sagittal sinus
frontal crest
attaches to falx cerebri, a strong membrane between the two hemispheres of the brain
foramen cecum
transmits a small vein from the frontal sinus to the superior sagittal sinus
lacrimal fossae
for the lacrimal glands
superior temporal line
anchors the temporal fascia
inferior temporal line
most superior extent of the temporalis muscle
parietal foramina
transmits a small vein through the parietal to the superior sagittal sinus
sigmoid sulcus
trasnverse (sigmoid) sinus
petrous pyramids
separate the temporal and occipital lobes of the brain and housing the internal ear
zygomatic process
superior edge is an attachment for the temporal fascia, and its inferior edge anchors fibers of the masseter muscle
mastoid proces
muscles attached: sternocleidomastoideus, splenius capitis, longissimus capitis.
mastoid foramen
small branch of the occipital artery which supplies the dura mater, the diploe, and the mastoid cells
mastoid notch (digrastic groove)
attachment of the digastric muscle
occipital groove
lodges the occipital artery
styloid process
anchors the stylohyoid ligament
jugular fossa
houses the bulb of the internal jugular vein
carotid canal
transmits the internal carotid artery and the carotid plexus
internal auditory meatus
transmits the facial and acoustic nerves (cranial nerves 7 and 8), as well as the internal auditory artery
external occipital crest
passes between the right and left nuchal musculature. anchors the nuchal ligament
condylar foramina
perforate the occipital at the depth of the condylar foassae, where each transmits an emissary vein
hypoglossal canals
give exit to the hypoglosal nerves (cranial nerve 12) and entrance to arteries
infraorbital foramen
transmits the infraorbital nerve (a division of cranial nerve 5) and vessels to the face
lacrimal canal
houses the nasolacrimal duct. which drains tears inferiorly into the nasal cavity
incisive canal
transmits the terminal branch of the greater palatine artery and the nasopalatine nerve
greater palatine groove
for the greater palatine vessels and nerve
greater palatine foramen
perforates the rear corner of the hard palate and is formed as the alveolar process of the maxilla meets the horizontal plate of the palatine. transmits the greater palatine vessels and nerve
lesser palatine foramina
for the transmission of lesser palatine nerves, are located on the posterolateral corner of the hard palate foramina, near the junction of the perpendicular and horizontal plates
nasopalatine grooves (vomer)
lodge nasopalatine nerves and vessels
cribiform plate (ethmoid)
perforated by olfactory nerves (cranial nerve 1) as they pass up to the brain from the mucous lining of the nose
crista galli
perpendicular projection of the cribiform plate of the ethmoid into the endocranial cavitiy. It is interposed between olfactory bulbs, and its posterior surface anchors the falx cerebri, a fold ot the dura mater extending into the longitudinal fissure of the brain between the two cerebral hemispheres
zygomaticofacial foramen
passage of the zygomaticofacial nerve (division of cranial nerve 5) and vessels
zygomaticoorbital foramina
passage of the zygomaticotemporal and zygomaticofacial nerves (divisions of cranial nerve 5)
zygomaticotemporal foramen
transmits the zygomaticotemporal nerve
optic canals (sphenoid)
optic nerve (cranial nerve 2) and opthalmic artery pass through these canals on their way to the eyeballs
hypophyseal (pituitary fossa)
holds the pituitary gland
foramen rotundum
maxillary nerves (another division of cranial nerve 5) that run just inferior to the superior orbital fissures
foramen ovale
transmit the mandibular nerve and accesory meningeal arteries
foramen spinosum
transmit middle meningeal vessels and branches from the mandibular nerves
anterior clinoid processes
posteriormost projections of the lesser wings. These give attachment to the tentorium cerebelli, a segment of dura mater that separates the cerebellum from the occipital part of the cerebral hemispheres of the brain
angular spine
inferiormost projection of the greater wing, serves as an attachment point for the pterygospinous ligament
medial pterygoid plate
provide attachment for the medial pterygoideus musles, which are mandibular elevators
