Lazarus Hunter on Instagram: "READ THE CAPTION📖 While often celebrated for the beautiful range of skin tones it creates, melanin is far more than just a pigment—it’s a sophisticated biological polymer with deep roots in our physiology. • Brain Power: Beyond the skin, neuromelanin is found in key areas of the brain like the substantia nigra, where it acts as a protective shield for neurons. • Neural Origins: Melanin-producing cells share the same embryonic origin as our nervous system (the neura

Medical Student on Instagram: "Parkinson’s disease is a long-term (chronic) neurological disorder that mainly affects movement, but it can also affect thinking, mood, sleep, and the autonomic nervous system. What’s going wrong in the brain? • Deep in the brain is an area called the substantia nigra. • Cells there make dopamine, a chemical that helps control smooth, coordinated movement. • In Parkinson’s, these dopamine-producing cells gradually degenerate and die. • Less dopamine → the brain has

medicoshub on Instagram: "🧠 Parkinson’s Disease – Understanding the Festinating Gait In Parkinson’s disease, degeneration of dopaminergic neurons in the substantia nigra pars compacta leads to classic Parkinsonian symptoms—resting tremor, rigidity, bradykinesia, and changes in gait. 🚶‍♂️ Festinating Gait is a hallmark feature: • Short, small shuffling steps • Steps may rapidly accelerate • Often preceded by freezing episodes, where the patient struggles to initiate movement This gait pattern o

What is Parkinson’s Disease? Parkinson’s disease is a progressive neurological disorder that affects movement. It happens when nerve cells in the brain (especially in an area called the substantia nigra) gradually break down and produce less dopamine — a chemical that helps control smooth and coordinated muscle movements. It usually develops slowly and commonly affects people over 60 years, but it can occur earlier. #trioshospitalityacademykhandbari #trioshospitalityacademy #nepalicoffee #coffee

Dopamine is a chemical substance (neurotransmitter and hormone) produced in the brain specifically within the substantia nigra, ventral tegmental area (VTA), and hypothalamus. It is released into the synapse (the space between two neurons) to communicate messages throughout the brain and body. Dopamine isn’t solely responsible for happiness But is a key neurotransmitter in the brain’s reward system, creating feelings of happiness, pleasure, motivation, and satisfaction. #health #happiness #menta
