In which areas of the body would you expect to find the most merkel discs and tactile corpuscles? why?

Merkel discs and tactile corpuscles are found in the hairless skin layers like in lips and finger tips among the body parts.

Explanation:

Merkel cells was first discovered by Friedrich Merkel in 1875 and hence the cells were named after him. They are found in the epidermal layer of the cell.

They are found in the layer of the skin which helps in transmitting tactile signals. There are various types of tactile mechanoreceptors that work together during the process of touch. The Markel cells are encapsulated when touched.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
