What is the earliest time that centers of ossificatoin appear in the. Cartilaginous vertebra?
during the 7th embryonic week
Ossification begins in which region of the embryonic vertebral column?
the lower cervical-upper thoracic region
What is the ratio of primary to secondary centers of ossification for a typical vertebra?
3 primary centers: 5 secondary centers
What are the names of the primary centers of ossification for a typical vertebra?
centrum centers and neural arch centers
How many primary centers of ossification appear in the typical vertebra?
three… 1 for the centrum, 2 for the neural arches
What is the classification of the joint forming between primary centers of ossification?
cartilage synchondrosis/amphiarthrosis synchondrosis
What are the names of the synchondroses forming between primary centers of ossification in the typical vertebra?
neuro Central synchondrosis and neural arch synchondrosis
What are the names of the five secondary centers of ossification for a typical vertebra?
tip of the transverse process, tip of the spinous process, epiphyseal plate centers
How many secondary centers of ossification appear in the typical vertebra?
five… 1 for the tip of each transverse process, 1 for the tip of the spinous process, 1 for each epiphyseal plate
What is the classification of the oint forming between secondary centers of ossification and the rest of the typical vertebra?
cartilage synchondrosis/amphiarthrosis synchondrosis
What are the names of the synchondroses forming between secondary centers of ossification and the rest of the typical vertebra?
tip of the transverse process synchondrosis, tip of the spinous process synchondrosis, and epiphyseal ring synchondrosis
