Bones of the Vertebral Column Flashcards
main support of the body and protects the spinal cord
vertebral column
vertebral bones are classified into two:
typical and atypical
consists of all parts of the ordinary vertebrae
typical vertebrae
The second to eighth vertebrae
typical vertebrae
lack some of the parts of the ordinary vertebrae
atypical vertebrae
first, ninth, and tenth
atypical vertebrae
the central mass of the body of the vertebra which concave anteriorly and convex posteriorly
centrum
large central opening which lodges the spinal cord
neural canal
the posterior projection from the centrum of a vertebra and it forms the roof of the vertrbral canal
neural arch
it consists of median posteriorly directed spines known as?
neural spine
paired prominent lateral projection known as
transverse processes
two types of zygapophysis
prezygapophyses and postzygapophyses
types of typical vertebra
centrum
neural canal
neural arch
zygapohysis
the first vertebral bone which articulates with the occipital condyle of the skull
atlas
it has no transverse process and prezygapophyses
atlas
locate the other parts which have baeen preiously studied in a typical vertebra
atlas
the ninth vertebral bone which articulates with the eight typical vertebra superiorly and with the urostyle inferiorly
sacral vertebra
the tenth vertebral bone. it is a long, slender trangular shaped bone between the anterior portions of the pelvic girdle
urostyle
at the dorsal part it has a medial elevation known as the
keel
extends the entire length of the bone
