Random information on the term “Sensory organ”:

The Bulbous corpuscle or Ruffini ending or Ruffini corpuscle is a slowly adapting mechanoreceptor located in the cutaneous tissue of humans. More precisely, these detectors are located between the dermal papillos and the subcutaneous. It is named after Angelo Ruffini.

Ruffini corpuscles are enlarged dendritic endings with elongated capsules.

This spindle-shaped receptor is sensitive to skin stretch, and contributes to the kinesthetic sense of and control of finger position and movement. In particular they are at the highest density around the fingernails where they are believed to be useful for monitoring slippage of objects along the surface of the skin, allowing modulation of grip on an object.

Ruffini corpuscles respond to sustained pressure and show very little adaptation.

Ruffinian endings are located in the deep layers of the skin, and register mechanical deformation within joints, more specifically angle change, with a specificity of up to 2.75 degrees, as well as continuous pressure states. They also act as thermoreceptors that respond for a long time, so in case of deep burn there will be no pain as these receptors will be burned off. Classically regarded as a thermoreceptor, the Ruffinian endings/corpuscle is not actually a thermoreceptor but is rather a mechanoreceptor.

Random information on the term “EAR”:

An ear is the grain-bearing tip part of the stem of a cereal plant, such as wheat or maize. It can also refer to “a prominent lobe in some leaves”.

The ear is a spike, consisting of a central stem on which grow tightly packed rows of flowers. These develop into fruits containing the edible seeds. In corn, it is protected by leaves called husks.

In some species (including wheat), unripe ears contribute significantly to photosynthesis, in addition to the leaves lower down the plant.

A parasite known as Anguina tritici (Ear Cockle) specifically affects the ears on wheat and rye by destroying the tissues and stems during growth. With exception to North Africa and West Asia, the parasite has been eradicated in all countries by using the crop rotation system.
