Biology 210 Homework #8 Fall 2023

10- Use the concept of sensory adaptation to explain how sensory adaptation occurs for either the sense of smell or touch. Be very detailed in your explanation and include the terms sensory receptor, firing rate, perception, and brain in your explanation.

eople entral hervous system. 2. What is meant by sensory transduction and how are ions and membrane potentials involved? 3. How can the brain interpret action potentials from different stimuli into meaningful integration? In other words how does the brain distinguish between different pitches of sound or distinguish between pain and heat signals 4. Briefly describe how action potentials are produced from mechanoreceptors, photoreceptors and chemoreceptors. rades anopto Recordings neck Shoreline E- lail ay Howard Library

3. The Sense of Hearing Sound Production - Labeling Activity 1 The figure below events are numbered A-G in the order they happen. Read the descriptions of the events bellow and place the correct letter in the blank before its description. represents the chain of events that result in the perception of sound. These A) B A. Oval window movement sets up fluid wave inside the cochlea that stimulates the hair cells of the organ of Corti. B. Temporal lobe interprets nerve impulses as sound or balance. C. Sound waves enter external auditory canal. D. Sound waves cause tympanic membrane to vibrate. E. Vestibulocochlear nerve carries impulses to temporal lobe of brain. F. Tympanic membrane causes auditory ossicles to move. G. Movement of stapes causes oval window to move in and out. 356 Special Senses: Hearing and Equilibrium | Laboratory 17 © bluedoor, LLC

3 pts Question 12 The human ear is able to hear an amazing range of sounds. As your movie begins, you hear the opening score, what is the first step in the hearing cess that allows you to hear these sounds? O Vibrations from the eardrum are passed to the ossicles (tiny bones). O The moving liquid bends tiny hairs in your inner ear. O The auditory nerves turn the movements of the tiny hairs into signals and sends them to the brain. O The outside part of the ear catches the sound waves traveling through the air.

Q4 Person who has problem with hearing but has fully function eardrum and middle ear is intend to use cochlear implant as hearing aid which functionally to carry sounds from environment into ears and make them louder. (a) Describe the common parts of hearing aid device. (b) Suggest additional components and functions of hearing aid device that could be improved to give more benefit to users.

9. Control of Breathing: Stimulus Sensory nerves Control center Motor nerves Effectors Response

11. Name and define the three routes of the visual system? Give an example of how each work.

Q3.Discuss the anatomy of ear with diagram and also explain its functions in short.

1. Explain the roles of sensory nerves in how do humans receive odors and scents?

32.Enumerates five sensory receptors? thanks asap

Can Dolt Exercise 1: Indicate the correct answer(s) and correct the false ones: 1- Light can be detected by human eye. ( ) 2- The speed of light is 300,000 m/s. ( ) 3- Light, like sound, cannot propagate in vacuum ( ) 4- Moon is an example on luminous objects ( ) 5- Light is an example on waves. (O

31. Enumerates five sensory receptors? thanks

Please ASAp. Thanku. What is the tonotopic anatomical organization of cells in the auditory brain? a.The anatomical organization of cells according to the temporal pattern of sounds b.The anatomical organization of cells according to the loudness of sounds c.The anatomical organization of cells direction from which a sound comes d.Anatomically organization of cells according to the frequency to which cells respond best

4. Use what you know about the anatomy and physiology of special sensory organs to evaluate how each of the following changes will impact an Animal's ability to sense its environment. A mutation produces a non-functional ligand-gated channel, which normally binds glucose. Which special sense(s) will be impacted by this mutation? The stereocilia on "hair cells" become stiffer as Vertebrates age. Identify the senses that will be impacted by this change; then, describe one specific example of how the perception of a stimulus will change due to this age related stiffening.

please asap. thanku You discover a new species of frog in extremely dark parts of the Amazon rain forest. You hypothesize that this frog detects light using a mechanism similar to mammals. If you are correct, which types of drugs would interfere with vision in this frog?

5. Review of sensory systems Choices: Olfaction; Audition; Nociception; Cones; Kinesthesis; Vestibular; Rods On your retina the and in combination these cells produce signals for all the colors of visible light. b. cells react to different wavelengths in particular blue-violet, red, and green a. Our sense of sound is called membrane and these cells can be permanently damaged if exposed to loud noise.. C. The sense of smell is called flavor of foods as you detect the spices and aromas of the dish. and depends on the movement of the hair cells on the basilar and it plays an important role in the perception of the d. contributes to staying balanced by providing information about position and motion of the body as the brain receives signals from your joints, tendons and muscles. The sense of pain is called injury, the more cells stimulated, the more signals to the brain, the more it hurts. е. and it relates to the number of cells stimulated by the

5. Explain the difference between hearing and listening. Include key points or limitations of either process

32.Enumerates five sensory receptors? thanks urgently

18. Establish the physical relations of sound wave length to frequency and pitch, and amplitude to loudness measured in decibels. *Describe how loud sounds damage hair cells.

Check Your Understanding 1. In what tissues or organs are Meissner's and Pacinian corpuscles located? What is the specific function of each? 2. Would you expect certain areas of the body to contain more sensory receptors? Why or why not? Did your results in Exercise 1 reinforce your expectations? 3. If the lips were tested for two-point discrimination, what results would you expect? Why?
