MHS 285 Spinal Ganglion

Tissue sections of .

What dye(s) was used to stain these specimens? [ + ]

Toluidine blue - a basic dye that binds nucleic acids, but preferentially stains RNA.

Are these sensory neurons bipolar, pseudounipolar, or multipolar? [ + ]

Pseudounipolar - single axon that splits into two branches - one process passes centrally, and another that originates peripherally

Where is the located? [ + ]

Centrally located nucleus

Are there synapses in these ganglia? [ + ]

No, just the cell bodies and axons of the sensory neurons

What are the aggregates in the cytoplasm of ? [ + ]

Nissl (or chromophil) substance

What are the supporting that surround ganglion cells? [ + ]

Satellite (or capsule) cells

Do sensory neurons relay information into or out of the CNS? [ + ]

They conduct impulses to the CNS (i.e., afferent neurons)
