BIO midterm Axial Appendicular skeleton Flashcards
axial skeleton consist of
skull
thoracic cage -sternum ribs
vertebral column (spine)
Appendicular skeleton
shoulder girdle: clavicle,spacula
upper limb
pelvic girdle
ilium, ischium, pubis
lower limb
axial bones form the _____
central axis of skeleton (spine)
Protects the
CNS-brain and spinal cord
Skull is divided into two regions such as (what bones)
facial and cranial bones
what are the cranial bones
frontal
parietal
occipital
temporal
sphenoid
ethmoid
what are the facial bones
mandible
maxilla
palatine
nasal
vomer
nasal conchae
zygomatic
lacrimal
when one cranial plate meets another is called
cranial suture: they are;
sagittal
coronal
lambdoidal
squamosal
frontal is positional at the
Front (anterior) (forehead) and superior region of the cranial vault
ethmoid and sphenoid forms the
anterior crania fossa
frontal create the
superior orbit of eyes
Frontal features
-supraorbital notch or foramen
-supraorbital margin
-glabella
-frontal sinus
-zygomatic process
frontal structure is associated with
coronal suture
coronal plane is
the superior surface of the cranial vault
cranial bones -parietal are
superior to the frontal, anterior to the occipital and posterior to the temporal lobe
create most of wall of cranial vault
Partial features list them
squamous suture
coronal suture
lambdoid suture
sagittal suture
temporal features of the cranial bone
-squamous and pterosal portions
-internal and external acoustic meatus
-mastoid process
-styloid process
-carotid canal
-zygomatic process
-mandibular fossa
