Mechanoreceptors: Merkel cells, Ruffini endings and more
Oct 8, 2024 · Bulbous corpuscles or Ruffini endings are slowly adapting, encapsulated mechanoreceptors located deep in the skin, ligaments and tendons. They are elongated, spindle-shaped specializations with their long axis usually oriented parallel to the stretch lines in the skin.
Bulbous corpuscle - Wikipedia
The bulbous corpuscle, Ruffini ending or Ruffini corpuscle is a slowly adapting mechanoreceptor located in the cutaneous tissue between the dermal papillae and the hypodermis. It is named after Angelo Ruffini.

Mar 26, 2024 · Bulbar corpuscles, also known as Ruffini corpuscles or Ruffini endings, are mechanoreceptors found in the reticular dermis and hypodermis of both glabrous and hairy skin, as well as in ligaments. They are slowly adapting mechanoreceptors which respond to stretch and movement and do not transmit discriminative touch stimuli.

Ruffini endings detect skin stretch and are also located within the dermis layer of the skin. The Meissner corpuscles are stimulated by skin motion and are located in the epidermis layer. The Merkel cells are located at the border between the dermis and epidermis and are specialized to detect edges and points.

Sep 4, 2023 · There are four major categories of tactile mechanoreceptors: Merkel’s disks, Meissner’s corpuscles, Ruffini endings, and Pacinian corpuscles. [1] Not much is known about the molecular actions that lead to tactile mechanoreceptor activation, which leads to subsequent signal transduction.
Mechanoreceptors – Introduction to Sensation and Perception
The bulbous corpuscles (also known as Ruffini endings) detect tension deep in the skin and fascia. The Merkel nerve endings (also known as Merkel discs) detect sustained pressure. The lamellar corpuscles (also known as Pacinian corpuscles) in the skin and fascia detect rapid vibrations (of about 200–300 Hz).
The Human Cutaneous Sensory Corpuscles: An Update - PMC
Ruffini corpuscles (Figure 5 and Figure 6) or endings are elongated, spindle-shaped formations, with a length of up to 2 mm and a transverse dimension of 150 m in their central or equatorial portion and 40 m at extreme losses or poles.
Touch sense: Functional organization and molecular determinants …
Ruffini endings are thin cigar-shaped encapsulated sensory endings connected to Aβ nerve endings. Ruffini endings are small connective tissue cylinders arranged along dermal collagen strands which are supplied by one to three myelinated nerve fibers of 4–6 µm diametre.
Ruffini endings - (General Biology I) - Fiveable
Ruffini endings are specialized sensory receptors located in the skin and connective tissues that respond to sustained pressure and skin stretch. They play a key role in proprioception, helping the body perceive its position and movement in space.
