Cognitive quiz 2

Question 1

__________________ receptors have large receptive fields

Answer 1

Ruffini’s endings and Pacinian corpuscles.

Ruffini’s endings (corpuscles - тельца) and Pacinian corpuscles are types of mechanoreceptors in the skin that respond to different types of mechanical pressure. These mechanoreceptors are responsible for detecting and transmitting information about mechanical stimuli, such as sustained pressure on skin (длительное надавление на кожу), stretch (растягивание), and vibration.

Медленно адаптирующиеся кожные механорецепторы, расположенные в соединительной ткани. Инкапсулированные чувствительные нервные окончания вытянутой формы.

Ruffini’s endings help you know where your body parts are and how they are moving. They allow the organism to respond to stimuli such as grasp (хватание).

Question 2

Pacinian corpuscles

Answer 2

are rapidly adapting mechanoreceptors that respond to sudden disturbances (нарушение) in the skin. They’re responsible for sensitivity to vibration and pressure. They are located in the skin and also in various internal tissues.

Ruffini’s endings and Pacinian corpuscles cover larger (крупные) areas of the skin, making them less sensitive to precise (точный) stimuli but more responsive to broader pressure changes or vibrations.
