The spinal ganglion, located in the dorsal root of the spinal nerve, contains the cell bodies of sensory neurons. These neurons transmit sensory information from the periphery (like touch, pain, or temperature) to the central nervous system (CNS). The ganglion is situated just outside the spinal cord, near the point where the dorsal root enters…[Read more]

The cerebrum is the brain's largest region, responsible for functions like thought, movement, and sensory processing. When an Agranular (AG) stain is applied to cerebral tissue, it highlights the brain’s cellular structure, helping researchers examine the details of neurons and supporting cells. This technique makes it easier to study the…[Read more]

Smooth muscle is the quiet worker inside your body, always at work without you even thinking about it. You’ll find it in places like your stomach, blood vessels, and intestines, helping move things along without you noticing.
