skull bones Flashcards
the spinal cord passes through a large foreman in the skull called the ——–
Foramen magnum
glabella
the small smooth area that locates between two supraciliary arches of the frontal bone
The frontal suture remnant called
metopic suture
he intersection of the frontal and nasal bones called
nasion
Inferior to the nasal bones is the pear-shaped area called
piriform aperture
inion
locate at the tip of the external protuberance
The superior nuchal line
The superior nuchal line
The zygomatic arch
he union of the temporal process of the zygomatic bone and the zygomatic process of the temporal bone
he pterion
It is usually indicated by an H-shaped formation of sutures that unite the frontal, parietal, sphenoid (greater wing), and temporal bones
are emissary foramina
that transmit emissary veins connecting scalp veins to the venous sinuses of the dura mate
Sella turcica in sphenoid bone
Sella turcica – a saddle-shaped depression. It has three parts:
Tuberculum sellae – forms the anterior wall of the sella turcica, and the posterior aspect of the chiasmatic groove.
Hypophyseal fossa – the deepest part of the sella turcica, where the pituitary gland is located
. Dorsum sellae – forms the posterior wall of the sella turcica.
the foramen rotundum which structure pass through it ?
the maxillary nerve
foramen ovale which structure pass through it
mandibular nerve
foramen spinosum which structure pass through it ?
middle meningeal vessels
Medial pterygoid plate of sphenoid process
supports the posterior opening of the nasal cavity.
