A Typical Vertebrae Flashcards
Arch forms from joining of posterior extensions
Vertebral arch
Bridge
Pedicle
Connects processes
Lamont
Two parts of vertebral arch
Pedicle and lamina
Canal for spinal cord to pass
Vertebral foramen
Lateral projections from vertebral arch
Transverse processes
Single projection from posterior vertebral arch
Spinous process
The spinous process is what?
Fused lamina
Where muscles attach
Transverse and spinous process
What does the superior and inferior projects allow vertebra to do
Form joints with adjacent vertebrae
Paired projections lateral to vertebral Foramen
Superior or inferior articular process
Cervical vertebrae are what vertebrae
C1-C7
What does the cervical vertebrae form
Neck region
Which of the cervical vertebrae are different
Atlas and axis which are the first two
What is special about the atlas and axis
Perform functions unlike other cervical vertebrae
What does the atlas allow you to do
Nod yes
Superior surface of transverse processes have large depressions to receive occipital condyles
Atlas
Unique characteristics of atlas
No body
Acts as pivot for rotation of atlas and skull
Axis
The large upright processes are called what and do what
Send and acts as a pivot point
What allows you to indicate no
Joint between atlas and axis
C3-C7 are called what
Typical vertebrae
What is special about the typical vertebrae
Smallest and lightest vertebrae
Spinous processes of the typical vertebrae are what
Short and divided into 2 branches
The transverse processes of typical vertebrae are what
Contain foramina for vertebral arteries to pass on the way to the brain
T1-T12
Thoracic vertebrae
In comparison to the cervical the thoracic are ?
Larger
What is special about the thoracic vertebrae
Articulate with ribs
The body of the thoracic is what?
Heart shaped
The two costal facets of the thoracic vertebrae do what
Receive heads of ribs
The transverse processes of thoracic vertebrae do what
Articulate with know like tubercles of ribs
What does the thoracic vertebraes spinous process look like
Long and hooks downward and looks like giraffes head when looked at from the side
L1-L5
Lumbar vertebrae
The bodies of the lumbar vertebrae are what
Massive and block like
Spinous processes of lumbar vertebrae
Short and hatchet shaped to look like a moose head
Most of the stress of vertebral column occurs in what
Lumbar vertebrae
How is the sacrum formed
Fusion of fiver vertebrae
What does the sacrum articulate with
Superiorly with L5
Inferior my with coccyx
The sacrums wing like alae articulate laterally with hip bones to form what joint
Sacroilic joints
Forms posterior wall of pelvis
Sacrum
End of spinal cord
Sacral hiatus
How is coccyx formed
3-5 vertebrae
Shape of coccyx
Tiny irregularly shaped
What is the coccyx
Tailbone or remnant of a tail that other vertebraes have
Disc like weight-bearing part of vertebrae faces anteriorly in vertebral column
Body or centrum
