A detailed medical educational infographic titled "Types of Receptors in the Human Body" showing all major receptor categories and their locations. Include these sections: 1. SENSORY RECEPTORS (Skin & Body): - Mechanoreceptors (Meissner's corpuscles, Pacinian corpuscles, Merkel's discs, Ruffini endings) - in skin layers - Thermoreceptors - in skin (hot/cold) - Nociceptors (pain receptors) - in skin, muscles, organs - Proprioceptors (muscle spindles, Golgi tendon organs) - in muscles and tendons - Chemoreceptors - in carotid body, aortic arch, brainstem - Photoreceptors (rods and cones) - in retina of eye - Osmoreceptors - in hypothalamus - Baroreceptors - in carotid sinus, aorta 2. CELL SURFACE / MEMBRANE RECEPTORS: - G-Protein Coupled Receptors (GPCRs) - throughout body - Ion Channel Receptors (Ligand-gated) - neurons, neuromuscular junction - Enzyme-Linked Receptors (tyrosine kinase) - liver, muscle - Cytokine Receptors - immune cells 3. INTRACELLULAR RECEPTORS: - Nuclear Receptors (steroid, thyroid, vitamin D) - in cell nucleus/cytoplasm 4. NEUROTRANSMITTER RECEPTORS: - Adrenergic (alpha, beta) - heart, blood vessels, lungs - Cholinergic (muscarinic, nicotinic) - autonomic ganglia, NMJ - Dopaminergic - brain (basal ganglia) - Serotonergic - GI tract, brain - Histamine - skin, stomach, brain Use a human body silhouette in the center with color-coded arrows pointing to locations. Use bright medical colors (blue, green, orange, red, purple). Clean white background. Professional anatomy textbook style with clear labels and legend.
