Testing ANS #shorts (Part B)

The video tutorial covers various aspects of spinal nerves, including the identification of a splanknik nerve and a post-ganglionic parasympathetic neuron. It explains the role of the Gray Ramus communicons in neuron exit from the sympathetic ganglion and outlines the CNS levels for sympathetic origin, specifically T1 to L2. The tutorial also identifies the celiac ganglion as a pre-aortic ganglion and discusses the lateral horn gray matter, which houses cell bodies for pre-ganglionic sympathetic neurons.

Which type of neuron is associated with the S4 spinal cord level?

• Motor neuron

• Sensory neuron

• Post-ganglionic parasympathetic neuron

• Pre-ganglionic sympathetic neuron

What is the function of the Gray Ramus communicons?

• It connects the spinal cord to the brain.

• It transmits sensory information.

• It houses cell bodies for motor neurons.

• It allows neurons to exit the sympathetic ganglion.

What are the CNS levels for sympathetic origin?

• T1 to L2

• L3 to S1

• S2 to S4

• C1 to C7

What type of ganglion is the celiac ganglion?

• Pre-aortic ganglion

• Dorsal root ganglion

• Cranial ganglion

• Paravertebral ganglion

What does the lateral horn gray matter house?

• Cell bodies for post-ganglionic parasympathetic neurons

• Cell bodies for pre-ganglionic sympathetic neurons

• Cell bodies for sensory neurons

• Cell bodies for motor neurons
