correct answers



Alae - CORRECT ANSWERS-Wing-like projections formed by fusion of the transverse
processes, that articulate laterally with the hip bones

Alveolar process - CORRECT ANSWERS-Superior margin of mandible; contains
sockets in which the teeth lie

Axial skeleton - CORRECT ANSWERS-Divided into 3 parts: skull, vertebral column, and
thoracic cage

Carotid canal - CORRECT ANSWERS-Opening medial to the styloid process through
which the internal carotid artery passes into the cranial cavity

Centrum - CORRECT ANSWERS-Rounded central portion of the vertebra, which faces
anteriorly in the human vertebral column

Coccyx - CORRECT ANSWERS-Human tailbone

Condylar process - CORRECT ANSWERS-Articulation point of the mandible with the
mandibular fossa of the temporal bone

Coronal suture - CORRECT ANSWERS-Point of articulation of parietals with frontal
bone

Coronoid process - CORRECT ANSWERS-Jutting anterior portion of the ramus; site of
muscle attachment

Cribriform plates - CORRECT ANSWERS-Bony plates lateral to the crista galli through
which olfactory fibers (cranial nerve I) pass to the brain from the nasal mucosa through
the cribriform foramina

Crista galli (cock's comb) - CORRECT ANSWERS-Vertical projection providing a point
of attachment for the dura mater, helping to secure the brain within the skull

, Ethmoid bone - CORRECT ANSWERS-Irregular shaped bone anterior to the sphenoid.
forms the roof of the nasal cavity, upper nasal septum, and part of the medial orbit walls

External acoustic meatus - CORRECT ANSWERS-Canal leading to eardrum and
middle ear

Foramen lacerum - CORRECT ANSWERS-Jagged opening between the petrous
temporal bone and the sphenoid providing passage for a number of small nerves and
for the internal carotid artery to enter the middle cranial fossa

Foramen magnum - CORRECT ANSWERS-Large opening in base of occipital, which
allows the spinal cord to join with the brain

Foramen ovale - CORRECT ANSWERS-opening posterior to the sella turcica that
allows passage of a branch of the fifth cranial nerve

Foramen rotundum - CORRECT ANSWERS-Opening lateral to the sella turcica
providing passage for a branch of the fifth cranial nerve

Foramen spinosum - CORRECT ANSWERS-Opening lateral to the foramen ovale
through which the middle meningeal artery passes

Frontal bone - CORRECT ANSWERS-Anterior portion of cranium; forms the forehead,
superior part of the orbit, and floor of anterior cranial fossa

Glabella - CORRECT ANSWERS-Smooth area between the eyes

Greater wings - CORRECT ANSWERS-Portions of the sphenoid seen exteriorly anterior
to the temporal and forming a part of the eye orbits

Hypoglossal canal - CORRECT ANSWERS-Opening medial and superior to the
occipital condyle through which the hypoglossal nerve(XII) passes

Incisive fossa - CORRECT ANSWERS-Large bilateral opening located posterior to the
central incisor tooth of the maxilla and piercing the hard palate; transmits the
nasopalatine arteries and blood vessels

Inferior nasal conchae (turbinates) - CORRECT ANSWERS-Thin curved bones
protruding medially from the lateral walls of the nasal cavity; serve the same purpose as
the turbinate portions of the ethmoid bone.

Infraorbital foramen - CORRECT ANSWERS-Opening under the orbit carrying the
infraorbital nerves and blood vessels to the nasal region.

Internal acoustic meatus - CORRECT ANSWERS-Opening on posterior aspect of
temporal bone allowing passage of cranial nerves VII and VIII
