Definition of Pacinian corpuscle in English:
Pacinian corpuscle
nounpəˈsɪnɪənpəˌsinēən ˈkôrpəs(ə)l
Anatomy An encapsulated ending of a sensory nerve that acts as a receptor for pressure and vibration.
Example sentencesExamples
- Hair follicles and smooth muscle (arrector pili), sweat and sebaceous glands, and Pacinian corpuscles are located in the reticular layer.
- Snakes have simple nerve endings for vibration perception and Herbst corpuscles in birds and Pacinian corpuscles in Eutherian mammals allow for perception of vibrations.
- Lamellated corpuscles, similar to Pacinian corpuscles, ‘have been found in the legs of kangaroos and are thought to detect ground - borne vibrations.’
- Preliminary results reveal a high density of Pacinian corpuscles in the front of the foot and along the edges - a finding consistent with the notion that elephants are sensing seismic signals when they press their feet on the ground.
- The feet of elephants are more than mere clumping cylinders; their interiors are filled with vibration sensors known as Pacinian corpuscles, which have a structure similar to an onion, with a slimy gel between each layer.
Origin
Late 19th century: named after Filippo Pacini (1812–83), Italian anatomist.
