For example, the Scarabaeidae have lamellate antennae that can be folded tightly for safety or spread openly for detecting odours or pheromones. The insect manages such actions by changes in blood pressure, by which it exploits elasticity in walls and membranes in the funicles, which are in effect erectile.
For example, the temperature modality is registered after heat or cold stimulate a receptor. Some sensory modalities include: light , sound , temperature , taste , pressure , and smell . The type and location of the sensory receptor activated by the stimulus plays the primary role in coding the sensation.
Taste buds are clusters of taste receptor cells, which are also known as gustatory cells. [1] The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue , soft palate , upper esophagus , the cheek , and epiglottis .
Taste is the perception stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with the sense of smell and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food and other substances.
Object A is a taste bud, object B is a taste receptor cell within object A, and object C is the neuron attached to object B. I. Part I is the reception of hydrogen ions or sodium ions. 1. If the taste is sour, H+ ions, from an acidic substances, pass through their specific ion channel. Some can go through the Na+ channels.

Sucrose (table sugar) is the prototypical example of a sweet substance. Sucrose in solution has a sweetness perception rating of 1, and other substances are rated relative to this. [13] For example, another sugar, fructose, is somewhat sweeter, being rated at 1.7 times the sweetness of sucrose. [13]
Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with smell ( olfaction ) and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food or other substances.
