Question

Fill ups with correct stains:

1. ______ stain fills neurons black
2. ______ stain is nuclear, stains somas
3. ______ stain fills axons

Answer 1

The correct stains are: Golgi stain for entire neurons, Nissl stain for cell bodies, and neurofibrillary or silver stains for axons. These histological techniques are pivotal in neuroscience for visualizing different neuron structures.

Step-by-step explanation:

The correct stains needed to fill in the blanks for the student's question about neuron components are:

1. Golgi stain fills neurons black.
2. Nissl stain is nuclear, stains somas.
3. Neurofibrillary stain or silver staining fills axons.

These stains are used in neuroscience to visualize different parts of neurons. The Golgi stain is used to impregnate the entire neuron, including dendrites, axons, and the cell body, giving a black appearance under a microscope. The Nissl stain binds to RNA, which is abundant in the cell body or soma, making it appear purple or bluish. For axons, neurofibrillary stains, mainly silver stains, are utilized to identify the long processes of neurons that are otherwise difficult to see.
