What provides innervation of the epineurium.

Answer 1

Nervi nervorum. They are afferent branches off the primary nerve fibers.

Question 2

What is the Epineurium histologically?

Answer 2

Deep Fascia

Question 3

What provides blood supply to nerves?

Answer 3

Segmental arteries along the epineurium and the vasa nevorum

Question 4

What provides blood supply to the nerve roots?

Answer 4

Segmental/radicular arteries

Question 5

What is the outermost layer of arteries?

Answer 5

Tunica adventitia

Question 6

Which nerve fibers innervate the outermost layer of arteries?

Answer 6

Unmyelinated C fibers

Question 7

Question 9

How does Brian explain a Tender Point?

Answer 9

Areas of surface hyperalgesia that can be related to any anatomical (MS, viscera, vascular, neural…) system. Trigger points (Trp) are a MS version of Tender Points. They are hyperalgesia (TP) locations located in the MS system. Trp are part of the nocifensive “muscle guarding” reflex, protecting underlying fascial dysfunction of any MS or non-MS structure.
