Nerves GSA Pathways

Question 1

1 blank

Answer 1

the “skin place” has a “d” dermatome and the “skin place” is innervated by the “n” nerve.

Question 2

2 blank

Answer 2

the signal travels down the “n” nerve, to lateral cord, to superior trunk,( how does it go through brachial plexus) to the ventral raumus of the “d” spinal nerve,

Question 3

3 blank

Answer 3

down the spinal nerve, through the dorsal root ganglion, through the dorsal root, into the dorsal horn of the “d” section of the spinal cord

Question 4

1 medial forearm

Answer 4

The medial forearm has a a T1 dermatome and the medial arm is innervated by the medial cutaneous nerve of the forearm

Question 5

2 medial forearm

Answer 5

The signal will travel down the medial cutaneous nerve of the forearm to medial cord, to inferior trunk, to the ventral ramus of the T1 spinal nerve

Question 6

3 medial forearm

Answer 6

down the spinal nerve, through the dorsal root ganglion, through dorsal root, into dorsal horn of the T1 section of the spinal cord

Question 7

1 skin of back directly over vertebral column

Answer 7

Does not specify location on back so will say T2 dermatome.

Question 8

2 skin of back directly over vertebral column

Answer 8

Signal will travel down along the dorsal ramus of T2, to the spinal cord

Question 9

3 skin of back directly over vertebral column

Answer 9

into dorsal root ganglion, through dorsal root, into the dorsal horn of the T2 section of spinal cord
