Mostly Vertebrae and ribs
Which vertabrae does not have a body?
When consecutive vertebrae articulate, notches in their _________ create the intervertebral foramina.
A herniated disk occurs when _______.
the annulus fibrosus ruptures and nucleus pulposis pushes its way out
Which structure of the sternum articulates with the appendicular skeleton?
Typically, how many sacral vertebrae fuse to form the sacrum?
As a child, Jane had an lateral curvature of her spine and had to wear a brace. What type of abnormal curvature did Jane have?
Which vertebrae are found in the neck region?
What feature of general vertebrae project laterally from the neural arch and provide attachments for deep back muscles?
This inferior portion of the sternum is a landmark for the anterior attachment of the diaphragm and the superior surface of the liver. It can also be broken off during CPR.
how many of each vertabrae are there?
5 sacral (fused)
4 coccygeal (fused)
what are the primary and secondary curvatures of the vertebral column?
the primary are sacral and thoracic; secondary are cervical and lumbar
exaggerated posterior curvature of the thoracic region
exaggerated anterior curvature of the lumbar region
lateral curvature of the lumbar or thoracic region
with what does the inferior articular process of a vertebrae form a joint with>
the superior articular process of the vertebrae just below it
what types of joints are between the vertebrae?
synovial plane joints
between which vertebrae are intervertebral discs found?
start at joint between c2 and c3. continue until L5 and S1 because after that they are fused
what is in the very center of the verterbral disc? and just superficial?
nucleus pulposis; anulus fibrosiss
What are the distinguishing features of the cervical vertebrae?
small body; bifid spinous process; transverse foramen; triangular vertebral foramen;
distinguishing features of thoracic vertebrae?
medium sized bodies, two costal facets; long sharp inferior projecting spinous processes; circular vertebral foramen
distinguishing features of lumbar vertebrae
massive bodies; short blunt spinous processes that project posterior; triangular vertebral foramen; thin and tapered transverse processes
be able to label parts of vertebrae
the arrow points to a transverse costal facet
be able to label rib features
how many true ribs are there and what is a true rib?
ribs 1-7 are true ribs and they attach directly to the sternum via their own costal cartilage
how many false ribs are there?
pairs 8-12 are false ribs
which ribs are floating ribs?
no attachment to sternum
inferior articular facet & process
which are the only vertebrae to have transverse foramina? what passes through there?
cervical vertebrae; vertebral arteries
structure and green and which vertebrae
odontoid process (dens) and C2 (axis)
which ribs are considered irregular? why?
one and two are irregular because they are short, wide and flat
eleven and twelve are irregular because they are free floating and have no anterior attachments
