Structure of Individual Vertebrae
Parts of a typical vertebra include…
Parts of a typical vertebra include….
a body, a vertebral arch, and several processes
Look at slide 121 / 122 / 123 images to differentiate between the following:
Parts of a typical vertebra include a body, a vertebral arch, and several processes
Four types of vetebral processes shown
You’re doing swell
What are the four types of vetebral processes shown (seven total processes per vertebrae with four types)… (answer is on slide 122)
All four TYPES of these processes (seven total processes per vertebrae with four types) connect to the….
Transverse Process (2/ vertebrae)
Superior Articular Process (2 /vertebrae)
Inferior Articular Process (2 /vertebrae)
Spinous Process (1 / vertebrae)
These processes above connect to the pedicle
Imagine how the superior articular process and inferior articular process come together. What do we see in between these two processes and the vetebral body?
The intervetrebral foramen (slide 123)
A typical vertebrae has the following parts?
Body
Vetebral Arch
Vetebral foramen
Seven processes
Vetebral notches
The body of a typical vetebrae is used for:
weight bearing
The vetebral arch is made up of the:
pedicles and laminae
The vertebral foramen is where?
A large hole in superior view and look at image on slide 124
How many processes are in a typical vertebrae and of which type?
Seven processes
- 2 transverse
- 1 spinous
- 4 articular
is all vertebral foramina together
Spinal canal
slide 125 image
are 2 vertebral notches together
Intervertebral foramina

There are _ cervical vertebrae
7
There are 7 cervical vertebrae:
The first cervical vertebra is the ___. It supports the skull
The second cervical vertebra is the ___, which permits side-to-side rotation of the head
The third to sixth correspond to the ___ ____ of the typical cervical vertebrae
The seventh called the ___ ___ is somewhat different from vertebrae 3 through 6
There are 7 cervical vertebrae:
The first cervical vertebra is the atlas. It supports the skull
The second cervical vertebra is the axis, which permits side-to-side rotation of the head
The third to sixth correspond to the structural patterns of the typical cervical vertebrae
The seventh called the vertebra prominens is somewhat different from vertebrae 3 through 6
There are 7 cervical vertebrae:

The seventh called the vertebra prominens is somewhat different from vertebrae 3 through 6
There are 7 cervical vertebrae:
The first cervical vertebra is the atlas. It supports the skull
The second cervical vertebra is the axis, which permits side-to-side rotation of the head
The third to sixth correspond to the structural patterns of the typical cervical vertebrae
The seventh called the vertebra prominens is somewhat different from vertebrae 3 through 6
Smaller bodies but larger spinal canal
Transverse processes: shorter, with transverse foramen for vertebral artery
Spinous processes of C2 to C6 often bifid (divided by a deep cleft or notch into two parts.)
1st and 2nd cervical vertebrae are unique - atlas & axis
Typical Cervical Vertebrae (C3-C6)
What is different about Typical Cervical Vertebrae (C3-C6) in relation to the vetebral bodies and spinal canal?
In regard
Smaller bodies but larger spinal canal
What is different about Typical Cervical Vertebrae (C3-C6) in regards to the transverse processes?
Transverse processes: shorter, with transverse foramen for vertebral artery
What is different about Cervical Vertebrae (C2-C6) in regards to the spinous processes?
Spinous processes of C2 to C6 often bifid (divided by a deep cleft or notch into two parts.)
The _____ transmit the vertebral arteries
transverse foramina
There are two craniovertebral joints:
Atlanto-occipital joint: between the atlas and occipital bone of the skull
Atlantoaxial joint: between the atlas and axis
Atlanto-occipital joint
Atlantoaxial joint
are the two what?
are they synovial?
What about their range of movement?
Articulations involve?
These are the two craniovertebral joints
Craniovertebral joints are synovial joints
They have a wider range of movement than the rest of the vertebral column
The articulations involve the occipital condyles, atlas, and axis
between the atlas and occipital bone of the skull
Atlanto-occipital joint:
between the atlas and axis
Atlantoaxial joint:
Craniovertebral joints are ____ joints
They have a _________than the rest of the vertebral column
The articulations involve the ______, _____, and ____
synovial
They have a wider range of movement than the rest of the vertebral column
The articulations involve the occipital condyles, atlas, and axis
