Summary Introduction
Introduction:
As a sensory receptor cell gets stimulated, it generates an electrical signal termed as receptor potential. Receptor potential differs in size, unlike the action potentials. Receptor potential contains large size in a sensory receptor cell and can stimulate action potentials with high frequency in axons leading from the sense organ to the brain. These type of receptor potentials are able to detect touch and temperature felt on the skin.

An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc.
How do we sense different types of pain (very painful vs. not painful at all)? Using your knowledge of threshold potential and the all-or-none principle, explain how it is possible to sense different levels of pain.
A pin can be pressed against the skin lightly and elicit no response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc.
Use what you know about threshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain)

The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination. Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity. A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.arrow_forward
