When the p-value is less than the level of significance (α), the null hypothesis is rejected. If the p-value so observed is not less than the significance level α, then theoretically null hypothesis is accepted.

Self antigens are not uncommon in the periphery, Two factors contribute to this:                                                                                                                             a. not all self a. antigens are expressed in the central lymphoid organs where negative selection occurs

b. there is a threshold requirement for affinity to self antigens before clonal deletion is triggered, allowing some weakly self-reactive clones to survive the weeding-out process.

Somatosensory receptors are divided into the major groups of receptors according to specific sensation: 

Mechanoreceptors (for touch and proprioception)

Thermoreceptors (for temperature)

Nociceptors (for pain or noxious stimuli)
