14

What happens inside the IVF

Spinal nerve is born, called the radical. Created from the ventral root and dorsal root combining. Also where the radicular arteries enter the vertebral column to meet the spinal cord.

15

GSA function

Sensory information from the skin, as well as muscle sense, tendon sense and joint sense from deeper structures

16

What does the ANS innervate

Smooth muscle, glands,

17

Is the vagus parasympathetic or sympathetic?

parasympathetic

18

Where are there intermediolateral nuclei?

From T1-L2, but the sympathetic chain ganglion can exist in higher cervical areas or lower lumbar areas. There are only grey and white communicans T1-L2.

19

Do GVAs express pain?

No they do not. They express pain through GSAs through referred pain.

20

Can GSAs express reffered pain?

Yes they can to other somatics. Example is the phrenic nerve to the diaphragm, pain is felt in the C3, C4, C5 dermatomes.

21

Where is T10 dermatome

above the belly button

22

Where is T4 dermatome

nipple line

23

Where is T6 dermatome

Xyphoid process

24

late pain vs. reffered pain

referred pain is felt early on, in the nerve specific dermatome. Late pain is felt later, and is activiated through a nearby GSA nerve that is in the muscle/dermatome

25

What is the sympathetic highway?

The GVEs have specific root values, and then they descend down to their effectors through a two nerve system. GVAs travel back up from the effector back to the DRGs that have the same root values. They then activate GSAs in those DRGs, leading to the referred pain patterns.
