The sense of pain is transduces by tonic receptors. What adaptive significance might this have?
Give typing answer with explanation and conclusion
Part II. Outline the events that shows the negative feedback loop that happens when
you (choose only one): get a wound, consume too much sugar, get hot by being in a
humid place, feel cold, drink too much water, touch a hot surface, get pinched or
pricked, or are in a poorly lit room. You are encouraged to do research on the
mechanisms that enables the responses for these.

Which is True and which is False?
The receptors that allow us to sense linear acceleration as our airplane takes off are located in the middle ear.
The human sensory homunculus devotes considerable space to the larger parts of the body, such as the torso and legs.
Athletes in contact sports like boxing and football readjust their sensitivity to pain, not just their attitudes.

- Distinguish between innate and learned behavior. Explain how an experiment using optogenetics could demonstrate the concept of “fire together, wire together” Predict whether a given change in receptors or neurotransmitter release is likely to strengthen or weaken a synaptic connection. Hypothesize how a channel or another molecule in a plant or animal would detect outside stimuli such as touch, chemicals, or light. Predict how perturbations in light levels, retinal, opsins, and cation channels in photoreceptors affects the photoreceptor’s membrane potential and neurotransmitter release. Given information about a neuron’s responses to stimuli, hypothesize what its receptive field might be.arrow_forwardwe are talking about the process of detecting a stimulus, processing it and then creating a response. pick an example and explain the process that takes places during these steps.arrow_forwardAfter a leg injury, pain makes a person avoid putting too much weight on the affected leg. Shielding the injury gives it time to heal. An injured insect shows no such shielding response. Some have cited lack of such a response as evidence that insects do not feel pain. But insects do produce substances similar to our natural pain killers. Is the presence of these compounds in insects sufficient evidence to conclude that they feel pain?arrow_forward
- You are listening to a deep bass beat (a very low pitched sound). Which statement best describes how neurons in the primary auditory cortex are activating? Group of answer choices Neurons in the rostral end of the primary auditory cortex are activating most Neurons in the caudal end of the primary auditory cortex are activating most Neurons in the middle of the primary auditory cortex are activating most All the neurons in the primary auditory cortex are activating a similar amountarrow_forwardThe brain’s somatosensory cortex does not consist of neurons that receive information equally from all parts of the animal’s body. Describe an example of this by identifying a relevant animal and the body parts that are disproportionately high in neuronal input to the somatosensory cortex.arrow_forwardSlowly adapting receptors include all the following types, except :-a- Golgi tendon organsb- warmth receptorsc- free nerve endingsd- Meissner corpusclesarrow_forward
- During a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. A second student responded that the behavior might frighten predators. Which statement best describes these explanations? A. The first explanation is correct, but the second is incorrect. B. The first explanation refers to proximate causation, whereas the second refers to ultimate causation. C. The first explanation is biological, whereas the second is philosophical. D. The first explanation is testable as a scientific hypothesis, whereas the second is not.arrow_forwardWhat would happen to the ability to smell if a drug that inhibited adenylate cyclase were applied to the olfactory epithelium of a vertebrate?
