CRANIUM
Occipital Bone
51
largest foramen, cranial fossa
foramen magnum
52
oval/convex, yes
occipital condyle
53
occipital medial, nerves
hypoglossal canal
54
- the most prominent midline projection on the posterior surface of the bone just above the foramen magnum
external occipital protuberance
55
- lies at the middle part of the base of the skull
| - This is also called the keystone of the cranial floor
sphenoid bone
56
- a bony saddle-shaped structure on the superior surface of the body of the sphenoid
sella turcica
57
- The anterior part of the sella turcica, which forms the horn of the saddle, is a ridge
tuberculum sellae
58
- The seat of the saddle is a depression
- contains the pituitary gland. The posterior part of the sella turcica, which forms the back of the saddle, is another ridge called the dorsum sellae
hypophyseal fossa
59
- project laterally from the body and form the anterolateral floor of the cranium
greater wings of the sphenoid bone
60
- which are smaller, form a ridge of bone anterior and superior to the greater wings.
- Forms the floor of the cranium and posterior orbit of the eye
lesser wings of the sphenoid bone
61
- through which the optic (II) nerve and ophthalmic artery pass into the orbit.
optic foramen or canal
62
- This fissure may also be seen in the anterior view of the orbit
- Blood vessels and cranial nerves pass through this fissure.
supraorbital fissure
63
- project inferiorly from the points where the body and greater wings of the sphenoid bone unite
pterygoid process
64
- At the base of the lateral pterygoid process in the greater wing
foramen ovale
65
- covered in part by a layer of fibrocartilage in living subjects
- It transmits a branch of the ascending pharyngeal artery
foramen lacerum
66
- The maxillary branch of the trigeminal (V) nerve passes through the foramen rotundum.
- Anterior and medial parts of the sphenoid
foramen rotundum
67
- a delicate bone located in the anterior part of the cranial floor medial to the orbits and is spongelike in appearance
ethmoid bone
68
- a partition that divides the nasal cavity into right and left sides
nasal septum
69
- anterior floor of the cranium and forms the roof of the nasal cavity
- The cribriform plate contains the olfactory foramina through which the olfactory nerves pass.
cribriform plate
70
- which serves as a point of attachment for the falx cerebri, the membrane that separates the two sides of the brain.
- Triangular process
crista galli
71
- which forms the superior portion of the nasal septum
perpendicular plate
72
- ethmoid bone compose most of the wall between the nasal cavity and the orbits
- contain 3 to 18 air spaces called ethmoidal cells
- two scroll like shaped
lateral masses
73
- small, flattened, rectangular-shaped bones that form the bridge of the nose
- These small bones protect the upper entry to the nasal cavity and provide attachment for a couple of thin muscles of facial expression
nasal bone
74
- are thin and roughly resemble a fingernail in size and shape
- These bones, the smallest bones of the face, are posterior and lateral to the nasal bones and form a part of the medial wall
lacrimal bone
75
- Two L-shaped
- form the posterior portion of the hard palate, part of the floor and lateral wall of the nasal cavity, and a small portion of the floors of the orbits
palatine bone
76
- which are inferior to the middle nasal conchae of the ethmoid bone, are separate bones, not part of the ethmoid bone
- scroll-like bones
inferior nasal conchae
77
- a roughly triangular bone on the floor of the nasal cavity that articulates superiorly with the perpendicular plate
vomer
78
- unite to form the upper jawbone
| - They articulate with every bone of the face except the mandible (lower jawbone)
maxillae
79
- the bony roof of the mouth, and is formed by the palatine processes of the maxillae and horizontal plates of the palatine bones
hard plate
80
- that empties into the nasal cavity
maxillary sinus
81
- a ridgelike arch that contains the alveoli (sockets) for the maxillary (upper) teeth
alveolar process
82
- horizontal projection of the maxilla that forms the anterior three-quarters of the hard palate.
palatine
83
- an opening in the maxilla inferior to the orbit, allows passage of the infraorbital blood vessels and nerve, a branch of the maxillary division of the trigeminal (V) nerve.
infraorbital foramen
84
- posterior to the incisor teeth
| - It transmits branches of the greater palatine blood vessels and nasopalatine nerve
incisive foramen
85
- structure associated with the maxilla and sphenoid bone
| - located between greater wing shaped of the sphenoid and maxilla
inferior orbital fissure
86
- Cheekbones
| - They articulate with the frontal, maxilla, sphenoid, and temporal bones.
zygomatic bones
87
- projects posteriorly and articulates with the zygomatic process of the temporal bone to form the zygomatic arch
temporal process
88
- lower jawbone, is the largest, strongest facial bone
| - only movable skull bone (other than the auditory ossicles, the small bones of the ear).
manible
89
- an anterior coronoid process (KOR-ō-noyd) to which the temporalis muscle attaches
TMJ
