🔬 Mammal Cerebellum
– The occipital and temporal lobes of the cerebral cortex are supported by a tissue called the cerebellum, also known as the “little brain.” Over 50% of all neurons in the brain are found in the cerebellum, while making up only 10% of the overall volume of the brain. Because most of the cerebellum’s outputs go to areas of the motor system and because injury to the cerebellum impairs posture and motor control, the cerebellum has historically been regarded as a motor structure. The cerebellum does not produce motor orders; instead, it changes the descending pathways’ motor commands to improve the accuracy and adaptability of movements.

🔬 Epithelial Tissue
– The epithelium, also known as epithelial tissue, lines the body cavity and forms the skin’s outer layer. It creates the lining of the reproductive, digestive, respiratory, and excretory systems. They carry out a number of tasks, including secretion, sensation, protection, and absorption.

🔬 Nerve Fiber Teased
– The long, thin projections of nerve cells, also known as neurons, that transmit electrical impulses away from the nerve cell body are known as nerve fibers, or axons. Normally, a neuron’s cell body has a single nerve fiber that sends impulses to neighboring neurons, muscles, or glands. Additionally, it makes it possible to measure the size of the myelin segments made by Schwann cells and characterize pathologic alterations that impact the invested axons, internodia, and paranodal areas.

🔬 Frog Simple Squamous Epithelium
– Desquamated cells from the outermost layer of the oral mucosa exhibit the shape and behavior of isolated squamous cells. The preparation displayed here uses a standard bright field microscope to capture little detail; differential interference contrast is used to improve the image. A entire mount of the layer of flattened cells that makes up the peritoneal lining of the coelom can be seen, along with the nuclei, cytoplasm, cell membrane, and thin, scale-like appearance of the cells.
