Viral infections are common in babies and children and often cause a minor rash of the skin. These rashes are usually harmless and will go away on their own. Different viruses can cause different rashes, and sometimes different viruses can cause rashes that look the same.
receptors for both lipid-soluble and lipid-insoluble hormones are found within the cell and usually within the nucleus. receptors for lipid-soluble hormones are on or in the cell membrane, whereas receptors for lipid-insoluble hormones are inside the cell.
Once inside of the cell, these lipid soluble hormones... bind with a specific receptor molecule inside the cytoplasm. In response to injury, cell fragments called platelets get activated to induce clotting. Activated platelets release factors that can in turn bind to specific membrane receptors on nearby cells.
