9.1 Sensory Reception Stimulus & Response Stimulus – detectable change in internal or external environment of an organism that produces a response in an organism • Ability to respond to stimuli – increases chance of survival e.g. detect and move away from harmful stimuli • Surviving organisms have greater chance of raising offspring – passing alleles to next generation‚ therefore a selection pressure favouring organisms with more appropriate responses Stimuli – detected by receptiors‚ transform

More Than One Reality By: Ethan Caldwell Reality is kind of like a memory. Everyone has their own different ideas of what it should be but none are necessarily the truth. For example two people who were both in the great depression could have totally different thoughts on the difficult times.

Both of them would have very different memories

Cutaneous receptors are sensory receptors located in the dermis‚ which is a layer of the skin. These receptors are responsible for sensations of touch‚ pressure‚ heat‚ cold‚ and pain. They are classified asmechanoreceptors which are associated with pressure‚ thermoreceptors which are associated with temperature‚ and nociceptors which are associated with pain (Brodal). Functional Anatomy There are five mechanoreceptors‚ free nerve endings‚ Meissner’s corpuscles‚ Pacinian Corpuscles‚ Merkel’s

concluded my discovery of space worm touch receptors is definite. Regardless of the type‚ sensory receptors are influenced by physical actions and various stimulus. My research and experiments show that space worm touch receptors are no different. Stimulus is a change discernible by the body (Sherwood 2004) or in my case‚ a space worm. Certain receptors like touch receptors respond to stimulus weakly or strongly when involved with a different stimulus (Sherwood 2004). This perfectly related to

SENSORY ORGANS Introduction The knowledge of the world around us stimulates our sensory organs to provide us with the information of what is going on around us. All sensory information is picked up by the sensory receptors‚ specialised cells that monitor internal and external conditions. Examples of sensory organs are: SENSE ORGAN Eye Ear (Organ of Corti) Ear (Semicircular Canals) Ear (utricle and saccule) Olfactory mucous membrane Taste Buds Skin Skin Skin Skin Various Muscle Spindle Golgi tendon
