Label the following structures on the
Subclavian A.
Label the following structures on the
Subclavian A.
What is this?
Where does this travel?
Vertebral A.
*Travels through the transverse foramena of the cervical vertebrae
***Goes along the posterior arch of tha atlas to enter the foramen magnum
What is this?
Suboccipital Triangle
What artery can be identified with this view?
What nerve can be identified with this view?
- Vertebral A. (*travels over posterior arch of atlas)
- Suboccipital N.
Why do we care about the vertebral A. when we are studying the muscles of the back?
The vertebral A. are what produce the…
Spinal Arteries
(Posterior and Anterior)
*they are tiny, not going to look for them in lab
Identify this:
Transverse Cervial A.
Identify this:
Transverse Cervical A.
Identify this:
Dorsal Scapular A.
Identify this:
Dorsal Scapular A.
When does the subclavian a. change name?
When it passes the 1st rib, becomes the…
axillary a.

Identify the following:
Thoracodorsal A.
Identify the following:
Thoracodorsal A.
In cadaver lab, typically how to you distinguish a

Darker
(b/c looking through thin wall of vein to preserved blood that’s stuck inside)
In cadaver lab, typically how to you distinguish a
ARTERY
ROUNDER
MORE SQUIGGILY
In cadaver lab, typically how to you distinguish a

The spinal cord is enlarged at:
- Cervical region
- Lumbosacral region
*more neural tissue there
What does the medullary cone represent?
Spinal cord ends
What is the cauda equina?
(Posterior to medullary cone)

Arch of the Aorta:
What are the three major arteries/trunks that come off the Arch of the Aorta?
- Brachiocephalic Trunk
- Left Common Carotid A.
- Left Subclavian A.
Off of the arch of the aorta, leading through the braciocephalic trunk…
What two arteries bifurcate?

Costocervical Trunk
What arteries come off of the thyrocervial trunk?
- Inferior Thyroid A. –> (Ascending cervial A. )
- Suprascapular A.
- Transverse Cervical A.
The ascending cervial a. produces what three branches in the upper cervical region?
- Equatorial Branches (supply vertebrae)
- Periosteal Branches (supply periostium of vertebrae)
- Spinal Branches (only at cervical regions)
What do spinal branches produce?
Anterior/Posterior Vertebral Canal Branches
Anterior/Posterior Radicular As.
