Reflex and Sensory Physiology
Purpose:
What is the purpose of this exercise?
The purpose of this lab is focus towards testing our reflexes and sensory physiology. We use these every day but we rarely do understand how much they contribute to our ability to function normally. A reflex is a rapid, involuntary motor response to stimuli. We will be conducting several experiments to test our reflexes throughout this lab.
Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken.

So if our nasal passages are blocked we would be able not distinguish flavors.
Questions:
A. Why are taste and smell receptors called chemoreceptors?
Taste and smell receptors are called chemoreceptors because specialized sensory organs adapted for excitation by chemical substances.
B. Why is taste so closely associated with smell?
Taste and smell share similar pathways to the brain and are influenced by the same stimuli. Both taste buds and olfactory bulbs are in a group of receptors known as chemoreceptors in the case of smell it’s the aromatic gases that trigger a response. In taste, it’s the mixture of chemicals with saliva in the mouth that trigger a response.
C. Propose a reason why appetite may be lost when someone has a head cold.
A reason why appetite may be lost when someone has a head cold is because you cannot taste as well because your nose is congested.
Exercise 8: Hearing
Observations:
Distance from ear to where ticking became inaudible ___18___ cm
Describe what was observed as you moved the ticking device around to different areas of the …show more content…
The subject’s foot off the floor, eyes closed had to put hand out for balance after 30 seconds or so.
Questions:
A. Where is balance processed in the brain?
The Cerebellum
B. What can be concluded about the effect of vision on balance?
Vision plays a direct and important role in stabilizing balance by means of providing the nervous system with continually updated information regarding the position as well as movements of body segments in relation to each other and the environment.
C. What is the function of the otolithic membrane?
The otolithic membrane is a gelatinous membrane is located in the vestibular apparatus of the inner ear, and it plays an essential role in the brain's interpretation of equilibrium.
Conclusions:
What do sensory and reflex tests tell about the functions of the nervous system as a whole?
The central nerves system receives sensory information from other parts of the body or the body's external environment and it transmits motor information to other parts of the body by way of the peripheral nervous system. Cranial nerve function is commonly assessed as part of a general physical examination of the head, eyes, ears, nose, throat, and neck. The tests provide a frame for how well our nervous system is taking in, processing, and also dispensing information to and from the Central Nerves System through the Peripheral Nervous
