Mr. Phettuccine is a 65 year old man who has been blind from birth and relies heavily on reading via Braille (touch-reading using raised dots). He has recently been diagnosed with a neurodegenerative disease and is worried it will affect his ability to read using Braille.

Using your knowledge of touch sensory physiology (M1L6), please answer the following questions with one or two (1-2) sentences each in the text box below.

Part A. Describe how lateral inhibition allows for localization of a touch stimulus. (1.5 marks)

Part B. If the neurodegeneration has reduced his touch lateral inhibition, what do predict would happen to his Braille reading? (1 mark)

Part C. What type of touch receptors do you predict would most be affected? Explain your reasoning. (1 mark 1).

As a dental radiographer, how do you feel you can become a better communicator with your patients?
Give three examples of things you can say (either verbal or non-verbal) to a patient to make them more comfortable.
Also, give three examples of how you would handle a patient with special needs to initiate cooperation during the exposure process.

Alan stands on a sharp object at home causing sharp pain in his foot. His knee buckles/bends immediately after standing on the sharp object.
Using your knowledge of somatic and autonomic reflexes (M4L4) answer the following questions. Be sure to clearly label the different parts.
Part A. Provide one example of a somatic reflex and one example of an autonomic reflex. (1 mark)
Part B. Identify two reflex pathways that are activated as a result of Alan standing on the sharp object. For each pathway identify: the specific receptor, all neurons and synapses involved and the impact on the specific effector tissue.

Make sure to highlight at least 3 areas; Must also include at least one research statement or specific scientific reference within this section. For example you could say “The Institute of Medicine recommends sports beverages over water when exercise exceeds blah, blah, blah

2.  touch on safety for all three beverages( water, sports drinks and coconut water); Do not include a general statement only; Be specific and think about safety from all angles (overhydration, specific ingredients, health concerns, etc

3.discuss the disadvantages of water over the sports beverage and coconut water, the sports beverage and coconut water over water. Make sure to highlight at least 3 areas; Must also include at least one research statement or specific scientific reference within this section. For example you could say “The Institute of Medicine discourages sports beverages when exercise is less than blah, blah, blah

4. include a specific recommendation of one of the three beverages for the main provider of fluids for the average person. You need to include three specific reasons as to why you are recommending that one beverage. you must state 3 specific reasons as to why you are selecting the beverage that you chose.

2. List the sequence of events that occurs between the entry of a sound wave into the external auditory canal and the firing of action potentials in the cochlear nerve.
3. Describe the functional relationship between the scala vestibuli, scala tympani, and the cochlear duct.

1. List at least two ways the retina has adapted to minimize the potential problem caused by the photoreceptors being the last layer of the retina that light reaches.
2. Describe the events that take place during accommodation for near vision.
3. Detail the separate mechanisms activated in photoreceptor cells in the presence and in the absence of light.
