Question 1

Upon entering the sympathetic chain ganglion,  a preganglionic sympathetic neuron can do :

Accepted Answer

SYNAPSE with postglanglionic neurons in the sympathetic chain ganglion it entered, or ascend/descend (up or down) the sympathetic chain to synapse in another trunk ganglion.

Question 2

It can do one pf the following

Accepted Answer

1- The postganglionic neuron can pass through the gray ramy communicans into the ventral or dorsal rami (through the back), to supply Visceral effectors (blood vessels, glands) of the head, neck, body wall, upper and lower limbs.

Question 3

Or 2)

Accepted Answer

The postganglionic neuron leaves the sympathetic chain ganglion by forming a sympathetic nerve (without passing the gray rami communicans)

Question 4

That innervates organs-

Accepted Answer

In the thoracic cavity (heart T1-T4 / lungs/bronchis T2-T4)

Question 5

Pass through the sympathetic chain ganglion, emerge without synapsing and do one of the following

Accepted Answer

Merge with other neurons that did the same to form the Splanchnic Nerve.
