Vertebrae and Spinal Cord Anatomy Flashcards
The hole through which the spinal cord runs is called the…
vertebral foramen.
The site at which vertebrae connect to one another is called…
the articular process.
The transverse process of the thoracic vertebrae connects to…
the ribs
The portion of bone which connects the transverse process to the spinous process is called the…
lamina.
The portion of the vertebrae which connects the vertebral body to the transverse process is called the…
pedicle.
The body, pedicle, and lamina surround the…
vertebral foramen.
The first and second cervical vertebrae are respectively called the…
atlas and axis.
The _______ runs through the transverse foramina of the cervical vertebrae.
vertebral artery
What is the ligament that attaches all of the cervical vertebrae on the posterior side of the neck?
Ligamentum nuchae.
The three branches of the erector spinae are the…
in order of medial to lateral
Spinalis, longissimus, iliocostalis
The veins that permeate through the vertebral column are collectively known as…
Internal vertebral plexus of veins
The internal vertebral plexus of veins is unique because the veins…
have no valves.
The epidural space is rich in…
epidural fat.
The first membrane of the spinal cord deep to the epidural space is the…
dura mater.
The holes in the sacru through which nerves of the cauda equina go are called the…
anterior and posterior sacral foramina
The large opening at the bottom of the sacrum is called the…
sacral hiatus.
Outline the structures that protect the spinal cord, starting with the dura and proceed by going deeper.
Dura, arachnoid, subarachnoid space, pia mater
What structure anchors the protective spinal membranes together?
The denticulate ligaments.
What is the terminal portion of the spinal cord called?
Conus medullaris
After the spinal cord has ended, the spinal nerves proceed through the lower vertebral column in the form of a structure known as the…
cauda equina.
What structure is the distal extension of the pia?
Internal medullary filum (filum terminale)
The structure through which the dorsal root passes through is called the…
intervertebral foramen.
What are the two portions of the intervertebral disk?
Outside: Annulus fibrosis
Inside: Nucleus pulposis
