Testing ANS #shorts (Part A)

The video tutorial provides an overview of the autonomic nervous system, focusing on the sympathetic chain and ganglion. It explains the role of the white ramus communicons in carrying preganglionic sympathetic neurons, detailing their pathways from the spinal cord to the sympathetic ganglion and back. The tutorial also covers the CNS levels associated with the parasympathetic system, specifically the brain stem and S2 to S4 spinal cord levels.

What is the anatomical structure referred to as the sympathetic chain?

• A group of parasympathetic nerves

• A series of sympathetic ganglia

• A collection of sensory neurons

• A network of blood vessels

Which part of the spinal nerve is associated with the sympathetic ganglion?

• Dorsal root

• Ventral root

• Sympathetic ganglion

• Cranial nerve

What type of neurons are found in the white ramus communicons?

• Postganglionic parasympathetic neurons

• Preganglionic sympathetic neurons

• Sensory neurons

• Motor neurons

At which CNS levels does the parasympathetic system operate?

• T1 to L2

• C1 to C5

• L5 to S1

• Brain stem and S2 to S4

Which of the following is NOT a function of the sympathetic nervous system?

• Increasing heart rate

• Relaxing airways

• Stimulating digestion

• Dilating pupils
