Question

tonic receptors Sound waves reaching the olfactory mucosa do not elicit olfactory perception due to the matching the type of stimulus of the receptor. not intensity To protect the body, potentially harmful substances emit an odor perceived as. modality A human's inability to perceive smells apparent to dogs represents insufficient of stimulus. unpleasant The unpleasurable chemical smells of dissection rooms become nonperceptible over time due to of phasic receptors. sensory adaptation equilibrium

Explanation / Answer

Answers:

Modality- Sound waves reaching the olfactory mucosa do not elicit olfactory perception due to the modality not matching the type of stimulus of the receptor

Unpleasant- To protect the body potentially harmful substances emit an odor perceived as unpleasant

Intensity- A human's inability to perceive smells apparent to dogs represents insufficient intensity of stimulus

Sensory adaptation- The unpleasurable chemical smells of dissection rooms become non perceptible over time due to sensory adaptation of phasic receptors

Other options in the question and their explanation:

Tonic receptors: Tonic receptors receive the stimulus constantly and slowly adapt such as receptors of pain, joint and muscle spindle

Equilibrium: It is divided into static equilibrium and dynamic equilibrium and not a general sense. The components involved in equilibrium in the body are vestibule, utricle, semicircular canals, vestibular nerve

When a person is still the kinocilia in the macula sacculi bend towards the inferior position and gives a static equilibrium. When there is a relative movement or when the body is in acceleration or changing the direction, it relates to the dynamic equilibrium

Explanation of the answers:

Modality: It refers to the sensory or stimulus modality which explains the perception after stimulus. The sensory modalities consist of light(photoreceptors), sound (mechanoreceptors), temperature (thermoreceptors), pressure(noci and tactile receptors) and smell (chemoreceptors).

In the given options sound waves are a kind of sensory modality which involves mechanorecptors and related to hearing, and they cannot have any effect on the olfaction (chemoreceptors), since olfaction has modality of smell which do not match with the sound.

Hence, the given question suits with modality

Unpleasant: The stimuli which are perceived are considered as unpleasant even without learning. This serves as a protective mechanism and warns the body to avoid the stimulus. It is helpful in avoiding harmful exposure to toxins, fumes etc

As the second definition speaks about harmful odour and protective behavior of the body, the blank is filled with unpleasant

Intensity: Sensory perception assess various aspects of stimuli perceived like modality (discussed in 1st option), intensity, location and duration of the stimuli

Although there are a number of stimuli brought afferent nerves, only some of them are selectively processed by the sensory system. Sometimes stimuli themselves are not perceived by the body as they lack the intensity to ring the threshold calibrated into the sensory system. The differential in various organisms is attributed to the minimum threshold or intensity of stimuli that they can perceive. It can be compared to the least count of instruments

As the given question, speaks about the perception in dogs which humans lack, it is due to the intensity of the stimuli and our body's inability to recieve such stimuli as it is below our threshold. Hence the answer is chosen as Intensity

Sensory adaptation: When a stimulus is recieved a number of times, brain slowly neglects the stimulus which is refered to as sensory adaptation. It is seen in almost all types of stimuli except pain stimulus

A common example is clothing, where stimulus from constant touch of clothes is neglected by the brain after sometime giving preference to other important stimuli

In the given question, it states that, unpleasant dissection smell stimulus getting non perceptible after habituation, this can be attributed to sensory adaptation

Hence, the answer is sensory adaptation
