Describe the saggital suture
articulates the two parietal bones within the saggital plane
Describe the coronal suture
connects frontal bone with parietal bones
Describe squamousal suture
the parietal bone on wither side articulates with it’s corresponding temporal bone
Describe the lambdoidal suture
connects occipital bone with the 2 parietal bones
What is a process
Bony projection used for muscle attachment
What is a condyle
smooth, rounded projection where bones meet, sits in fossa, moveable joints
What is a fossa
depressions in bone that can either be a apart of a moveable joint or holds an entire skeletal muscle, condyle sits in it
What is a foramen
openings that allow for blood vessels and nerves to pass through
What is a canal
openings that have a bony wall and resemble a tunnel of bone rather than a shallow foramen opening
What is a meatus
passageway to inner ear and middle ear
What bone does the zygomatic process articulate with?
zygomatic bone
What is the function of the external auditory meatus
passage to inner/middle ear that amplifies sound
Why is the zygomatic process called zygomatic process?
It is a process that articulates with the zygomatic bone
What bones have paranasal sinuses?
Ethmoid, frontal, maxillary, sphenoid
2 functions of sinuses
decrease weight of skull, resonate voice
What attaches to the crista galli?
Falx galli
Are inferior nasal conchae attached to ethmoid bone?
No they are free standing bones
What does the sphenoid bone look like?
A bat
What important structure is located in the sella turica of the sphenoid bone?
Pituitary gland
All foramina associated with sphenoid bone
foramen rotundum, foramen ovale, foramen spinosum
What general funtion do all sphenoid bone foramina share?
openings that allow blood vessels and nerves to pass through
Where is mandibular fossa located?
Temporal bone
Why is palatine process called that?
articulates with palatine bone
The palatine bones and two maxillae form what?
hard palate
Function of the foramen magnum
passage of the CNS through the skull, connects brain to the spinal cord
What bone do the occipital condyles articulate with?
Atlas vertebra
What bone do the foramen rotundum and optical canal belong?
sphenoid bone
Hyoid bone is where compared to larynx?
superiorly connected
Hyoid bone is where compared to the trachea?
trachea is inferior to the larynx and hyoid bone
Hyoid bone is where compared to the epiglottis?
epiglottis is posterior to the hyoid bone; directly behind it
What connective tissue makes up the epiglottis?
Elastic cartilage
What does the hyoid bone articulate with?
None
What crime was commited if the hyoid bone is found broken?
Strangulation
what are wormian bones
like tile filler in between the main cranial bones
what runs through the jugular foramen
jugular vein and cranial nerve
what part of the ethmoid bone is porous
cribriform plate
what is the dura mater
outer most part is made of dense fibrous tissue and attaches to the crista galli so we dont smack out frontal lobe on it
what are the foramen in the sphenoid bone
ROSL
rotundum
ovale
spinosum
lacerum
what runs through the foramen lacerum
carotid artery
what is the function of the nasal conchae
turbinance/acts like a mini centrifuge to get particulates out of the mucous membrane of the respiratory tract
