Animal Physiology Question

1. How do sensory neurons encode stimulus modality (i.e. type of stimulus), stimulus location, stimulus intensity and stimulus duration? Provide the level of detail necessary to understand these concepts, for hearing specifically. How does your brain distinguish low vs. high frequency sounds?

Expert Solution

Sensory neurons are those nerve cells of the Nervous System which are responsible to convert the external stimuli of the organisms involvement in the internal electrical impulse. This is the stimuli that can activate the motor neurons to get the contraction of the muscles. These are also known as neurones in the central nervous system which convert the specific form of stimulus.

Sensory neurons can encode the stimulus modality and symbol in two different ways. In a first way, the frequency of coding can be observed in which sensory neurons. This enhanced with the increased intensity. The second way the stimulus coding is observed in which the number of the different afferents and localization of stimulus is observed.The process of hearing possess the inner ear sound with the help of sensory neuron.One can hear the sound with help of spiral ganglionic neurones. These are ctivated with nervous system that is responsible to convert the external stimuli of the organism environment.

The brain can distinguished with the low and high frequency with the perception of pictures of those sounds. The high and low frequency are based on the auditory system in which it becomes easier to hear than others. Cochlea is that specialized cell with the spiral and number of lengths of stereocilia. This allowed hearing both high and low frequency sound.

Animal Physiology Question 1. Dynamic Range is the range of stimulus intensities over which a receptor can respond. Receptors that have a smaller (or narrower) dynamic range have much better discrimination of changes in stimulus intensity than receptors that have a large dynamic range (although I can’t test figures here, you should be able to draw a neuron with a wide vs. narrow dynamic range). Please explain the trade-off between dynamic range and discrimination using the relationship between number of...

Animal Physiology Questions 1. How do decreases in PCO2, pH, temperature and organic phosphate modulators (i.e. 2,3-DPG) shift the oxygen equilibrium curve of animals? If the oxygen equilibrium curve shifts to the right, how does that change an animal’s P50? How does it change its oxygen affinity? 2. We talked about a diversity of respiratory strategies used by animals in class. One of the main differences between fish & frogs compared to reptiles, and mammals was that fish and frogs...

Animal physiology question 1. Neurons use both graded and action potentials to carry electrical signals from one point to another. In a neuron, where do we find graded potentials? Where do we find action potentials? Describe the similarities and differences between these two types of signals that could be seen within an individual neuron.

The following question regards action potentials and neurons: 1.) A.) How is the physiology different for an excitatory synapse vs. an inhibitory synapse? Consider neurotransmitter differences, ion channel differences, and how they affect the potential of the post synaptic cell B.) (3 points) How is an electrical gradient produced across a gradient? How is this related to having a membrane potential? C.) (4 points) A) Describe negative feedback in physiology. B) How is negative feedback important for maintaining homeostasis? D.)...

Animal Physiology Question 1. Contrast ionotropic and metabotropic receptors. Specifically describe how they differ in their mechanisms of converting a sensory stimulus to a change in membrane potential. Provide one example of an ionotropic receptor we discussed in class and briefly describe how it works. Provide one example of a metabotropic receptor discussed in the textbook and briefly describe how it works.

How do parasympathetic neurons in the medulla respond to increased blood pressure? Which stimulus is detected by a chemoreceptor? What hormone is released to decrease blood pressure? Sheena's B lymphocytes (B cells) produced antibodies to protect her about 3-5 days after she was exposed to a virus. What type of immunity do antibodies provide? What should NOT elicit an immune response in your own body? What initiates T cell activation?

Animal Physiology. Compare and contrast the factors that influence energy use (i.e. field and standard / basal metabolic rates) in birds, mammals, and invertebrates. (A) Consider how Anna’s hummingbird and green anole lizards in Louisiana use energy. Use a point-by-point essay to compare and contrast the effects of (i) body size, and (ii) thermoregulatory strategy (endothermy/ectothermy & homeothermy/ heterothermy) on energy use in these two animals. - (B) Consider how bats in the Australian summer and winter clusters of bees...
