What is the molecular basis of touch sensation?
A)Pressure on the skin squeezes out chemical signals from epidermal glands.
B)Cell membrane distortion opens touch receptors,creating a receptor potential.
C)Pressure damages the delicate strands of skin cell DNA,activating a complex signalling cascade.
D)Pressure on sensory axons bursts vesicles and causes neurotransmitter release.

Question

Quizplus · Accepted Answer

When pressure is applied to the skin, it causes deformation of the cell membrane of touch receptors, which in turn open ion channels and create a receptor potential. This potential generates an electrical signal that is transmitted through sensory neurons to the brain, where it is interpreted as a sensation of touch.
