What are the characteristics of sutura vera? (true sutures)
sutures demonstrating interolocking of adjacent bone surfaces; typically formed by intramembranous ossification
What are the characteristics of sutura notha? (false sutures)
sutures lacking interlocking of adjacent bone surfaces; typically formed by endochondral ossification
Which sutures primarily interlock at their edges?
serrate and denticulate sutures
Which sutures will interlock and overlap at their edges?
Limbous sutures
Which sutures demonstrate non-interlock but will overlap at their edges?
Squamous sutures
Which sutures will neither interlock nor overlap at their edges?
Harmonia sutures
What were the classifications of sutura vera (true sutures) based on latin groupings?
serrate, denticulate and limbous
What were the classfications of sutura notha (false sutures) based on latin groupings?
squamous and harmonia

What is the norma lateralis?
skull viewed from side
What is the norma basalis?
skull viewed from bottom
What points on the skull are used to measure skull size?
Nasion, vertex, inion and gnathion
What points on the skull are used to measure cranial vault capacity?
Nasion, vertex and inion
What ostia are observed in the anterior cranial fossa?
Cribriform plate, anterior & posterior ethmoid foramina and foramen cecum
What are the contents of the optic canal?
Optic nerve and ophthalmic artery
What opening allows CN II to exit the cranial vault?
Optic Canal
What are the contents of the superior orbital fissure?
Ophthalmic veins, oculomotor nerve, trochlear nerve, ophthalmic division of trigeminal nerve and the abducent nerve
Ophthalmic artery and veins do or do not share the same opening?
Do Not
What are the contents of the foramen rotundum?
maxillary division of the trigeminal nerve
What are the contents of the foramen ovale?
The mandibular division of the trigemnal nerve and the lesser petrosal branch of the glossopharyngeal nerve
What are the contents of the foramen spinosum?
the nervus spinosus from the mandibular division of the trigeminal nerve and the middle meningeal artery
What are the contents of the foramen lacerum?
internal carotid artery, carotid sympathetic nerve plexus and a venous plexus
Wat are the contents of the hiatus for the greater (superficial) petrosal nerve?
The greater petrosal nerve a branch of the facial nerve
What are the contents of the pterygoid/vidian canal?
vidian nerve or nerve of the pterygoid canal
What are the contents of the hiatus of the lesser petrosal nerve?
lesser petrosal nerve, a branch of the tympanic plexus from the glossopharyngeal nerve
Which opening allows branch of cranial nerve IX to enter the infratemporal region from the middle cranial fossa/
Foramen Ovale
What forms the roof of the posterior cranial fossa?
Tentorium Cerebelli
What part of the cerebrum occupies the posterior cranial fossa?
none; only cerebellum, pons and medulla oblongata ae in the posterior cranial fossa
Which single opening allows the exit of the greatest # of cranial nerves from the posterior cranial fossa?
The jugular foramen
What bones form the jugular foramen?
Temporal and occipital bones
What cranial nerves are within the jugular foramen?
IX (glossopharyngeal), X (vagus), and XI (spinal accessory)
What is the jugular body/jugular glomus/tympanic body/tympanic glomus?
chemoreceptive organ within the wall of the jugular bulb
What is the function of the jugular body/jugular glomus/tympanic body/tympanic glomus?
chemoreceptive organ that monitors hypoxia, hypercapnia and increases in hydrogen ions(acidity)
What are the contents of the hypoglossal canal?
CN XII Hypoglossal Nerve
