Question 14

What happens inside the IVF

Answer 14

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.

Question 15

GSA function

Answer 15

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

Question 16

What does the ANS innervate

Answer 16

Smooth muscle, glands,

Question 17

Is the vagus parasympathetic or sympathetic?

Answer 17

parasympathetic

Question 18

Where are there intermediolateral nuclei?

Answer 18

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.

Question 19

Do GVAs express pain?

Answer 19

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

Question 20

Can GSAs express reffered pain?

Answer 20

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

Question 21

Where is T10 dermatome

Answer 21

above the belly button

Question 22

Where is T4 dermatome

Answer 22

nipple line

Question 23

Where is T6 dermatome

Answer 23

Xyphoid process

Question 24

late pain vs. reffered pain

Answer 24

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

Question 25

What is the sympathetic highway?

Answer 25

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.

Question 26

Heart referred pain DRG

Answer 26

Found C1-T5
