Hormone Collection (#11)

Polarised LM of crystals of insulin
Insulin. Polarised light micrograph of crystals of the hormone insulin. The crystals appear hexagonal in shape. The insulin molecule is made up of two chains of amino acids (A & B chains)

Thyroid parafollicular cell, TEM
Thyroid parafollicular cell, coloured transmission electron micrograph (TEM). This section has revealed the cells nucleus (light brown)

Stomach pylorus glands, light micrograph
Stomach pylorus glands. Light micrograph of a section through glands (pink) in the pylorus region of the stomach. Pyloric glands contain mucus cells and G cells that secrete gastrin

Thyroid follicle structures, TEM
Thyroid follicle structures. Coloured transmission electron micrograph (TEM) of a section through structures in a thyroid follicle

Cortisol hormone molecule. Computer model of a molecule of the steroid hormone cortisol. Atoms are represented as blobs and are colour-coded: carbon (green), hydrogen (blue) and oxygen (red)

Follicle stimulating hormone molecule. Computer artwork showing the secondary structure of a molecule of follicle stimulating hormone (FSH, bottom) and its receptor (FSHR, top)

Corticosterone hormone molecule, computer model. Atoms are represented as spheres and are colour- coded: carbon (pink), hydrogen (white) and oxygen (blue)

Erythropoietin molecule bound to receptors. Computer model of a molecule of erythropoietin (EPO) (orange) bound to two extracellular EPO receptors (pink and purple)

Prostacyclin, molecular model. This is a hormone that acts to widen blood vessels (thus lowering blood pressure) and to prevent aggregation of platelets (preventing blood clotting)

Insulin hormone, molecular model
Insulin hormone. Molecular model of the bovine form of the hormone insulin, produced by the pancreas in mammals to aid the body in metabolising sugars

Adrenaline hormone molecule
Adrenaline. Computer model of a molecule of the hormone and neurotransmitter adrenaline. It is also known as epinephrine. Adrenaline is produced by the adrenal glands

Dopamine molecule. Computer model of a molecule of the neurotransmitter and neurohormone dopamine. The atoms are represented as spheres and are colour-coded: carbon (red), hydrogen (white)

Insulin molecule
Insulin. Computer artwork of a molecule of insulin. Insulin is a hormone produced by the pancreas. It consists of two peptide chains, A (centre to right) and B (left)

"Hormone: The Intricate Symphony of the Body's Messengers" The medulla oblongata in the brain, a masterpiece of nature's artwork, orchestrates an intricate dance of hormones. Among them, oxytocin hormone crystals shimmer like precious gems under the microscope (PLM C016 / 7196), revealing their profound role in human connection and bonding. Delving deeper into cellular realms, a colored SEM image showcases mitochondria within ovarian cells, highlighting their crucial involvement in hormone production. Meanwhile, light micrographs capture oxytocin crystals (LM C016 / 7195) and insulin crystals (C017 / 8249), unveiling their mesmerizing structures that hold vital functions within our bodies. Exploring athlete physiology through captivating artwork unveils the remarkable impact hormones have on performance and endurance. These chemical messengers drive athletes to push beyond limits and achieve greatness. Artistic depictions also shed light on the complex world of molecular biology. An intricately designed insulin molecule stands as a testament to its pivotal role in regulating blood sugar levels while offering hope for those with diabetes. The pancreas anatomy comes alive through vibrant illustrations showcasing its significance as both an endocrine and digestive organ. It secretes essential hormones such as insulin that keep our bodies functioning optimally. Testosterone takes center stage with PLM capturing crystal formations that symbolize strength and masculinity. This hormone plays a fundamental role not only in physical development but also influences mood, cognition, and overall well-being. Returning to oxytocin - known as the "love hormone" - we delve into its dual identity as both neurotransmitter and hormonal messenger. Its delicate crystalline structure reveals itself once again under microscopic scrutiny (Oxytocin hormone crystals). Lastly, an artistic portrayal of thyroid anatomy reminds us how this small gland holds immense power over metabolism regulation (artwork C013 / 4675). Hormones secreted by this butterfly-shaped organ impact our energy levels, weight management, and overall health.
