Anatomy 1

Front 1

Nucleus pulposus is a remnant of and serves as

Back 1

notochord
shock absorber

Front 2

The disc is reinforced by

Back 2

the anterior and posterior longitudinal ligaments

Front 3

In adults the spinal cord ends at
In newborns the spinal cord ends at

Back 3

LV2
LV3

Front 4

In the cervical region, the cervical nerves exit

Back 4

superiorly to the respective pedicle of the vertebrae, this happens all the way through Cv7

Front 5

Cv8 exits

Back 5

inferiorly to the pedicle of cv7, from here on the nerves exit inferior to the respective vertebrae

Front 6

All sacral cord segments S1-S5 and coxygeal 1 lie

Back 6

opposite (posterior) to the body of Lv1

Front 7

Lumbar enlargment

Back 7

the lumbar enlargement givea attachment to the nerves which supply the lower limbs

Front 8

At each level where the spinal nerves come out theres a

Back 8

radicular artery which follows the roots into its respective canal. These do not reach the anterior and posterior spinal arteries

Front 9

How do radicular arteries help supply vertebral column?

Back 9

They connect to spinal arteries via anterior and posterior medullary arteries in lower levels of the spine

Front 10

In the thoracic region, segmental medullary arteries come off

Back 10

intercostal arteries

Front 11

In the cervical region segmental medullary arteries come off

Back 11

vertebral artery, ascending cervical artery, and deep cervical artery.

Front 12

Artery of Adamkieves significance

Back 12

associated to proper functioning of lumbar enlargement. It arises from lower intercostal arteries or the first lumbar artery. Usually found on the left side.

Front 13

In order to properly perform a lumbar puncture, in the lumbar cystern, we need to follow what plane at what level?

Back 13

supracrystal plane on Lv4.

Front 14

Which structures are penetrated in a lumbar puncture>

Back 14

Skin, superficial fascia, supraspinous ligament, innerspinous ligament, ligamentum flava, epidural fat, dura.

Front 15

Epidural injenction involves penetrating

Back 15

ligamentum flava and injecting an anesthetic which will diffuse through epidural fat and get to the nerve roots.
