You can see the node of ranvier in the longitudinal view

17
Q

Ventral root

A

Forward part of the peripheral nervous system

18
Q

dorsal root

A

Back part of the peripheral nervous system

19
Q

Spinal cord soma

A

Looks like a traditional neuron cell body, defined processes

20
Q

Spinal cord neurological cell nuclei

A

the dark spots behind the neuron, those are the cells that supply nutrients

21
