Q

At the intervertebral foramen, what is the relationship between spinal nerve number and vertebral number along the cervical spine?

A

in the cervical spine, spinal nerves exit above the segment they are numbered after (C8 is exception)
ex: C3 nerve exits above C3/between C2 and C3

2
Q

At the intervertebral foramen, what is the relationship between spinal nerve number and vertebral number along the thoracic and lumbar spine and the sacrum?

A

in the thoracic and lumbar spine and for the sacrum, spinal nerves exit below the segment they are numbered after (Co1 is exception)
ex: T6 nerve exits below T6/between T6 and T7

3
Q

What is the relationship between rib number and vertebral numbers at the costocentral joint?

A

rib number always equates to same vertebral number at the costocentral joint
rib 3 articulates with T3 segment and also with the T2 segment
only ribs 1, 11, and 12 typically joint with a single segment

4
Q

What is the relationship between spinal nerve number, rib number and vertebral number in a thoracic intervertebral foramen?

A

the spinal nerve number relates to the upper segment number in the vertebral couple
the rib number relates to the lower segment number in the vertebral couple
ex: T3 nerve exits the intervertebral foramen formed by T3/T4 and rib 4 joints with the vertebral couple
