WebTactile receptors. Merkel cells- Specialised cells present in the epidermis, sense light touch and softness. Meissner corpuscles- An encapsulated nerve ending, present at the upper part of the dermis. They can sense light touch and vibrations. Ruffini endings- These are also encapsulated, present in the dermis. WebT-cells are a subset of lymphocytes that play a large role in the immune response. The TCR (T-cell receptor) is a complex of integral membrane proteins that participate in the activation of T-cells in response to an antigen. Stimulation of TCR is triggered by MHC (major histocompatibility complex) molecules on cells with the antigen. burigi chato national park
