The glossopharyngeal nerve is involved in taste, salivation, swallowing, and speech. It also provides nerve supply to the tonsils and middle ear and regulates blood flow to the brain.

Researchers have measured the brain’s faint glow for the first time, hinting at a potential role of “biophotons” in cognition ...

Your first and shortest cranial nerve is the olfactory nerve. This nerve is one of two that don’t connect with your brainstem . Your olfactory nerve anatomy is a part of your central nervous system.

The obturator nerve begins in the lumbar plexus, a complex network of neural fibers located in your lower spine. It travels down through your pelvis and into your upper thigh, where it splits into ...

To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active ...

Next, the researchers genetically altered mice to disable the nerves carrying information from the inner ear to the brain ...

Diffuse axonal injury (DAI) is a type of traumatic brain injury (TBI). It refers to the shearing of the brain’s long connecting nerve fibers, or axons. DAI can occur during a motor vehicle ...

T he vagus nerve is a vine of nerve fibers with roots in nearly every organ and shoots in the brain. It helps us detect a racing heart, rising blood pressure, stomachache, discomfort, an ...

The sampled dorsal nerves contained between 4,926 and 5,543 nerve fibers each, or an average of 5,140 fibers. With two dorsal nerves per clitoris, that translates to about 10,280 nerve fibers that ...

Explore brain anatomy, from the cerebrum, cerebellum, ... (nerve fiber bundles), called ... Tightly packed endothelial cells lining the inside of the brain’s blood vessels work as a filter to ...
