 * Senses Homework**

(1) What is the function of a sensory receptor? They detect different types of stimuli.

(2) What is a exteroceptor? EXAMPLES TOO. Sensory Receptors that detect stimuli from outside the body. For example, taste, smell, sight, noises, etc.

(3) What is an interoceptor? EXAMPLES TOO. Sensory receptors that come from inside the body. For example, blood pressure, change in water-salt balance, monitor the pH level in blood.

(4) What is a chemoreceptor? EXAMPLES TOO. Chemoreceptor's respond to chemical substances close by. Taste and smell use the chemoreceptors as well as organs that are sensitive to internal stimuli.

(5) What is a pain receptor? EXAMPLES TOO. Pain receptors are types of chemoreceptors that respond to chemicals released by damaged tissues. They alert us to possible dangers.

(6) What is a photoreceptor? EXAMPLES TOO. A photoreceptor is sensitive to light energy. Our eyes use photoreceptors to provide to us a sense of light.

(7) What is a mechanooreceptor? EXAMPLES TOO. A Mechanooreceptor is stimulated by mechanical forces which most often result in some sort of pressure. When we hear mechanooreceptors are used.

(8 What is a thermoreceptor? EXAMPLES TOO. Thermoreceptors are located in the hypothalamus and skin and are stimulated by temperature change. Warmth receptors react to temperature rise and cold receptors respond when the temperatures drop.

(9) Explain sensation. Sensation is when the sensory receptors respond to environmental stimuli, sending off nerve impulses. Sensation is triggered when these impulses arrive at the cerebral cortex of the brain.

(10) What is sensory adaptation? Integration is what happens before sensory receptors initiate nerve impulses. Integration is the summing up of signals. Sensory adaption is a type of integration, and is a decrease to the responses of stimuli.
