Nervous or the nerve tissue is the major tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transfer nerve impulses and also gives nutrition to neurons.

This beautifully stained section of the cerebellum shows the classic three-layer organization: the outer molecular layer, the Purkinje cell layer, and the dense granule cell layer. The large Purkinje cells serve as key output neurons, while the medulla of white matter underneath supports rapid signal transmission. A perfect snapshot of how structure supports function in the nervous system!
This histologic, microscopic pictograph of the cerebellum reveals its multiple layers, including the molecular layer, Purkinje cells, granule cell layer, and the medulla of white matter. This image helps us visualize how the different layers work together to serve the function of the cerebellum, being a vital part of the brain that is responsible for coordinating motor control.
This image shows the cerebellum with its cerebellar cortex organized into three distinct layers, such as the outer molecular layer, the middle Purkinje layer, and the inner granular layer. The molecular layer appears light and contains few cells, mainly consisting of axons and dendrites. The Purkinje layer is a thin line of large, flask-shaped neurons that play a key role in motor coordination. Beneath the cortex is the white matter, which contains myelinated nerve fibers responsible for transmitting signals to and from the cerebellar cortex.
The cerebrum looks like a coral reef, it is the largest part of the brain. It controls thinking, memory, emotions, senses, and voluntary movements. It is divided into two halves called the left and right hemispheres.
It's amazing how the white matter is visible in this photo. The cerebellum contains both gray matter (cerebellar cortex) and white matter, with the gray matter further organized into three distinct layers: the molecular layer, the Purkinje cell layer, and the granular layer, each containing various specialized neurons and glial cells.
