(1) What is the function of a sensory receptor? - A sensory receptor is a dendrites that specializes in detecting certain types of stimuli.
 * Senses**

(2) What is a exteroceptor? EXAMPLES TOO. - An exteroceptor is a sensory receptor that detects stimuli from outside the body, such as smell, vision, taste and equilibrium.

(3) What is an interoceptor? EXAMPLES TOO. - An interorceptor recieves stimuli from inside the body, for example, changes to blood pressure and the pH in blood.

(4) What is a chemoreceptor? EXAMPLES TOO. - A chemoreceptor responds to chemical substances in the immediate vicinity, for example the combination of smells, sights and taste.

(5) What is a pain receptor? EXAMPLES TOO. - A pain receptor is a type of chemoreceptor that is a naed dendrite that responds to chemicals released by damaged tissues. For example, without pain receptors, we could never know if we have a stomach ulcer or internal bleeding.



(6) What is a photoreceptor? EXAMPLES TOO. - A photoreceptor is a type of sensory receptor that responds to light energy and provides us with a sense of vision. For example, we cannot see anything in the dark because our photoreceptors respond to light energy.

(7) What is a mechanooreceptor? EXAMPLES TOO. - A mechanooreceptor is a type of sensory receptor that is stimulated by mechanical forces. For example, we can feel someone pinch our arms because of our mechanooreceptors.

(8 What is a thermoreceptor? EXAMPLES TOO. - A thermoreceptor is a is a type of sensory receptor that is located in the hypothalamus and skin that is stimulated by changes in temperature. For example, without thermoreceptors, we would not be able to notice when we are burning ourselves.

(9) Explain sensation. - Sensation is when the nerve mpulses arrive at the cerebral cortex of the brain and conscious perception of stimuli occurs.

(10) What is sensory adaptation? - Sensory adaptaion is a type of integration where a decrease in a response to a stimulus occurs. For example, once you are aware and familiar with a certain smell, you stop noticing the smell.
