I think we’ve all had that kind of pain. A headache, maybe, or an injury. The kind of pain…that THROBS. You know what I mean. When I get one of those throbbing headaches, it’s like every beat of my heart is pushing the blood up through my brain, and with the blood comes another throb […]
After somewhat of a hiatus, the cranial nerves RETURN! After all, we can’t quit now! Only four more to go. And here’s where we’re at: Oh: Olfactory Oh: Optic and Optic 2 Oh: Oculomotor To: Trochlear Touch: Trigeminal And: Abducens Feel: Facial Virginia’s: Vestibulocochlear and Vestibulocochlear 2 Gucci: Glossopharyngeal Vest: Vagus Ah:Accessory Heaven: Hypoglossal So […]
Sci loves Portal. I think it’s a magnificently clever game, and Portal 2 is the in the same vein. I love the songs, I love the humor, and I love the concept (puzzle solving with a giant gun! That makes portals!), and I DESPERATELY want to play. I can’t. Sci, not unlike many people on […]
Today we move on in our tour of the cranial nerves to another nerve that is basically responsible for an entire system. In fact, it’s an overachiever…and does TWO. We’ve had the olfactory and the optic, and now, we welcome the vestibulocochlear, which does both auditory AND your sense of balance. The auditory system is […]
Ok, I had a lot of fun writing about the Trigeminal. Making it all about a Bollywood movie makes EVERYTHING better. Unfortunately, Bollywood movies do not apply to everything (but they DO apply to most things). So now, we move on to Cranial Nerve VII, the Facial nerve. Why, you say, WHERE was Cranial Nerve […]
You know, doing a series on the Cranial Nerves can get you down sometimes. I know this thing is going to be MAD useful for everyone (and may already be useful to many of you!) when it’s done. But right now, it’s “blah de blah nerve goes to the herp derp nucleus located in the […]
Today we continue ONWARD with the series on the Cranial Nerves. But we’re doing something a little different. Because last time we covered the Oculomotor Nerve, which innervates FOUR of the SIX muscles which control the eye, today we’re going to round out the eye (heh, round, eye, heh) and do the other TWO. But […]
In the last few posts we’ve covered the first two cranial nerves, the Olfactory and the Optic nerves (remember our mnemonic: Oh, Oh, Oh, To Touch And Feel Virginia’s Gucci Vest, Ah Heaven). Both of these cranial nerves carry sensory information IN to the brain for processing, and don’t really control motion. For nerves like […]
Last time we talked about the very basic anatomy of the eye. It was a lot of material. It’s too much. For you, I will sum up. Light and images come through the cornea and hit the lens. The lens flips the image backward. The light continues to the back of the eye, often to […]
…or rather, the visual system. Cause you can’t really talk about the optic nerve unless you talk about the rest of the eye along with it. We humans rely pretty heavily on vision as a species. At least, being able to see is a lot more important to our daily lives than, say, being able […]
