Neuron Collection (#15)

Acetylcholine crystals, light micrograph
Acetylcholine crystals, polarised light micrograph. Acetylcholine (ACh) is a neurotransmitter (nerve signalling chemical) that plays an important role in relaying impulses at myoneural (muscle-nerve)

Myelinated nerves, SEM
Myelinated nerves. Coloured scanning electron micrograph (SEM) of a section through myelinated nerve fibres and Schwann cells

NMDA crystals, light micrograph
NMDA crystals, polarised light micrograph. NMDA (N-methyl-D-aspartic acid) is an amino acid derivative and a neurotransmitter (nerve signalling chemical)

Glial cells, SEM
Glial cells. Coloured scanning electron micrograph (SEM) of a glial cell (centre). Glial cells are nervous system cells that provide structural support and protection for neurons (nerve cells)

Nerve cells and glial cells, SEM
Nerve cells and glial cells, coloured scanning electron micrograph (SEM). The nerve cells have small cell bodies (orange) and fine extensions called axons and dendrites (brown)

Gecko retina, SEM
Gecko retina. Coloured scanning electron micrograph (SEM) of an oblique freeze-fracture through the retina of a gecko (family Gekkonidae)

Glial cell, SEM
Glial cell. Coloured scanning electron micrograph (SEM) of a cultured glial cell (centre). Glial cells are nervous system cells that provide structural support and protection for neurons (nerve cells)

Nerve cell trauma response. Fluorescent light micrograph of a section through a spinal cord affected by multiple sclerosis (MS)

Brain tissue, light micrograph
Brain tissue. Light micrograph of a section through tissue from the mammalian brain, in this case from the cerebellum. The cerebellum is the part of the brain that controls sensory perception

Nerve growth factor, molecular model
Nerve growth factor. Molecular model showing the secondary structure of nerve growth factor (NGF). NGF is a small protein, which is involved in the growth

"Unveiling the Intricacies of Neurons: Exploring the Wonders Within Our Brain" Delving into the depths of our brain, we encounter a histological diagram of a mammalian retina. This intricate network showcases the complexity and beauty of neurons that enable us to perceive light and color. Moving further, we explore cerebellum tissue through a light micrograph. The mesmerizing patterns reveal nerve and glial cells working in harmony, orchestrating our body's movements with precision. Zooming in closer, we witness a synapse nerve junction captured by TEM. This microscopic marvel highlights how information is transmitted between neurons, forming connections crucial for our thoughts and actions. Shifting gears to SEM imagery, we are introduced to an awe-inspiring nerve cell. Its intricate structure resembles an elaborate work of art—a testament to nature's ingenuity in crafting these building blocks of intelligence. Tracing back history, we stumble upon Santiago Ramon y Cajal's 1894 drawing depicting cell types within the mammalian cerebellum. His meticulous observations laid foundations for understanding neural networks that govern our motor skills. Venturing deeper into brain tissue, we discover hippocampus tissue—an essential region responsible for memory formation and spatial navigation. Here lies another realm where neurons weave together memories that shape who we are. Intriguingly unique are Purkinje nerve cells found within the cerebellum—majestic giants among their peers. Their distinctive appearance signifies their vital role in coordinating movement and maintaining balance. As if peering through a microscope lens once again, another nerve cell captures our attention—the epitome of elegance amidst complexity; it reminds us how intricately woven life truly is at its core. Diving into glial stem cell culture under bright illumination reveals their remarkable regenerative potential—a beacon of hope for treating neurological disorders as they hold promises yet untapped. Examining brain tissue blood supply uncovers an indispensable lifeline, nourishing neurons with oxygen and nutrients.
