Alexey Kashpersky is a Ukrainian artist who created these impressive digital gross anatomy specimens using the program, ZBrush, along with a few other graphics tools. Many of the cadaver images were designed from real anatomical photographs, thus explaining the level of detail Alexey was able to achieve. buy kamagra gold online https://alvitacare.com/wp-content/languages/en/kamagra-gold.html no prescription
I think it would be great if medical students were given access to 3D Cadavers for learning purposes. I know this has been tried before, but not at this level of anatomical detail. buy vidalista online https://alvitacare.com/wp-content/languages/en/vidalista.html no prescription
Laura Facci is an artist from Caracas, Venezuela (she graduated from Design Institute of Caracas – Illustration Degree – in 2012). She created this anatomical alphabet for a school project, the assignment was simple — create an illustration for each letter of the alphabet, choosing a specific theme.
As you can tell, Laura chose the human body as her inspiration, and it turned out really well. buy naprosyn online buybloinfo.com no prescription
You may notice that the alphabet follows the Spanish language instead of English. buy Revatio online infoblobuy.com no prescription
B for Boca = Mouth. P for Piernas = Legs. O for Orejas = Ears… and so on. It might be a good Spanish test to see if you can name all of the words that match the drawings. buy neurontin online buybloinfo.com no prescription
Lucia Giacani is a fashion photographer hailing from Milan, Italy. Seen here is an editorial photo shoot for Vogue Italia called “Under My Skin.” I especially appreciate how the model’s glistening red hair matches the animal’s striated muscles.

The folks at Fabulous Cat Papers in Athens, Georgia have put together an incredible collection of hand embroidered notebooks featuring a bunch of beautiful designs. The classic anatomical illustrations really come to life with the addition of red and blue (arteries and veins, respectively) thread accents.
Welcome to “A Journey Through The Visual System”! I made this video to promote brain awareness for the general public. As a neuroscience researcher, I’ve always believed it’s important to help people understand the complexities of the human nervous system. Thus, I hope this video can be appreciated by kids and adults alike, and something will be learned by all.
The project was inspired by the old Magic School Bus show I used to love as a kid. In the video, you will go on a 5-minute journey from the eye all the way to brain, learning the neuroanatomy along the way.
If you are feeling kind, you can vote for the video here (before Sept. 30th). This was submitted as part of a contest hosted by the Society for Neuroscience and BrainFacts.org.
Anyway, thanks for watching!
Here is the script for the video in case you missed something important:
“We begin our journey with the eye, specifically the iris, which gives the eyes its distinctive color. Now, the iris can be green, or blue, or brown, or black depending on the level of melanin which it contains. When the lights go off, the muscles connected to the iris contract, which makes the dark circle in the center of the eye, the pupil, get bigger. When the light goes on, the pupil gets smaller to allow less light to enter. This is how the eye adapts to light.
Ahh, that must be Ellie. She’ll be our tour guide on this journey through the visual system. Hi Ellie, how are you? To get a better look at the visual system, we’ll need some light. Let’s observe the anatomy of the eye in a little bit more detail. If we peel away the skin, we can see the arteries and veins, which supply important nutrients to the area. Next, we can see the surrounding muscles, which help move the eye in all directions. Now, let’s cut the eye in half to see how light enters the visual system. First, it hits the cornea, the protective layer of eye. Then, through the whole in the iris known as the pupil. Lastly, the job of the lens is to bend light to focus it correctly on the retina.
It’s time to enter the eye. Ellie has her jetpack and now we’re looking at the surface of the inside of the eye. The optic nerve on the right is where all the nerve fibers leave the eye heading toward the brain. Let’s follow Ellie has she heads toward that dark spot in the distance. This is the fovea centralis, a small pit in the retina responsible for our sharpest, clearest vision. Foveal vision allows us to do things like read books, or drive cars, or play video games.
Now, let’s look at a cross-section of the retina to see how neurons respond to light. Light is absorbed by rods and cones, which are specialized photoreceptors. This starts a chain reaction, which excites the bipolar cells and then subsequently the ganglion cells, to send electrical signals off toward the brain. The amacrine and horizontal cells work to modulate the circuit. buy cialis sublingual online https://healthcoachmichelle.com/wp-content/languages/en/cialis-sublingual.html no prescription
Visual information flows along the optic nerve like a river of electricity. At the optic chiasm, the signals split such that images from the left visual field head to the right brain, and images from the right visual field head to the left brain.
After the optic chiasm, the visual signals make a quick stop at the lateral geniculate nucleus, or LGN. The LGN is organized into 6 layers, which all receive extensive feedback control from higher visual areas.
From the LGN, the visual signals travel along optic radiations back to the visual cortex. The cortex is where we use the signal that originally came from the eye to construct our visual reality. The billions of neurons in the human brain work to encode and process the information. Information is sent forwards and backwards. See, the beauty of the visual system is that everything we see is affected by our memories, and our feelings, and what we’ve seen before.
Well, that concludes our journey through the visual system, see you next time.”
