Grey Matter: The dark tissue of the brain and spinal cord, consisting mainly of nerve cell bodies and branching dendrites. White Matter: The paler tissue of the brain and spinal cord, which consists of nerve fibres with myelinated axons.

This 6 mins video from Khan Academy was by the far the best explanation than my whole semester in class. Thank you Khan Academy!

@emmag4355 2 года назад

A great bite-sized chunk of information. Just what I needed, as a new A&P student! If it's too long or slow for you, just change the playback speed of course. It was perfect for me & my ADHD.

Thank you for this. I have severe cervical stenosis and was just given my first MRI four years later and now found White matter brain disease. I had the MRI because the symptoms were very much like MS and I was growing concerned but there were no MS lesions. This helped me understand so much more what is occurring.

@mikeross1945 4 года назад

Question- So are the Nuclei in the gray matter of the brain self sustaining cells? I am confused because a nucleus is usually the control center WITHIN a cell

@Ginajoyy 2 года назад

In this case it's the name given to a group of nerve cells in the PNS it's called ganglia in the CNS it's called nuclei

@shagverywellable 2 года назад

Damn good info

@kmalkamel2999 9 лет назад

is ganglion the site where two neurons meet and what is the difference between pre and post ganglionic nerves

@salikte 4 года назад

ganglion is a site where there are a lot of PNS neurons. Pre GNs are nerves that synapse with the ganglion. Post GNs are nerves that emanate from the ganglion to the target cell

@Zetsuke4 2 года назад

Nice

@angelahurst3529 5 лет назад

Sir so basically the cell body of neuron face inside forming grey matter and axon part of it face outside forming white matter?

Could you please tell me if a brain has evidence of a generalised extensive white matter injury typically seen in children born prematurely would it be expected that there spine also would be effected by white matter?

🎯 Key Takeaways for quick navigation: 00:00 🧠 Gray matter holds neuron somas, and white matter has myelinated axons. 01:04 📚 Spinal cord's gray matter forms an "H," with white matter surrounding it. 03:03 🧠 Brain's gray matter is the cortex, while white matter is deep within. 04:57 🧠 Brain's deep gray matter is nuclei, and axon groups are tracts. 05:55 🧠 Central nervous system handles cognition, emotion, and consciousness, with a key role for the cerebral cortex.

@kingnostalgia7911 2 года назад

@j5hp 8 лет назад

If this was a good video, it would explain first what a nerve cell looks like. That the "soma" is the body of the cell and the "axon" is like a cable to transfer impulses from cell to cell.. Then gray and white matter would make more sense immediately.

@samm5893 8 лет назад

+j5hp There are videos that explain that stuff previous to this one by either Khan Academy or Khan Academy Medicine :)

How about dark matter?

@EnclaveHater07 3 года назад

But before we get into that, first let's talk parallel universes

@violinsheetmusicblog 7 лет назад

So why is the gray matter on the inside for the spinal cord??

@marklyne996 7 лет назад

violinsheets it is the collective neurones initially collecting around the brain stem, with the white matter/cerebrospinal fluid coating the spinal cord on the outside.

@dannichols6261 6 лет назад

I can't answer exactly, but it might be helpful to understand that the white matter is axons (signal conveying 'cables') that are running UP & DOWN in the spinal cord, conveying both motor and sensory information/signals, and the grey matter is the cell bodies (soma) & dendrites (inputs to those soma) which interface to some of those axons .
