Imagine rubbing your fingertips across a pane of smooth glass and then across a brick. what kinds of skin receptors you distinguish the two surfaces?

1)Meissner corpuscles

2) Pacinian corpuscles

3) Merkel Cells

Explanation:

These receptors mentioned above contributes to the tactile preception of the texture of the surface. As the smooth glass surface is smooth while the surface of the brick is slightly rough, these receptors senses it and produces a response. The meissner corpuscles are innervated by rapidly adapting afferents , Pacinian corpuscles are innervated by Pacinian afferents while Merkel cells are innervated by slowly adapting type 1 afferents.

his week a heat wave will be hitting, and most of the country will be experiencing temperatures above average for july. due to humidity, the temperature outside can feel even warmer than it actually is. this adjusted temperature, often referred to as the “feels like” temperature is called the heat index. the chart shows the heat index, which is calculated based on temperature and relative humidity. use this chart to answer the following questions.
