PRACTICAL TASK 15
Theme: THE SENSE OF TOUCH. SKIN RECEPTORS
Task № 1
Complete the sentences:
Free nerve endings, The Meissner's body, The tactile discs, The Pacini corpuscle.
1.__________________, is an encapsulated nerve ending, localized in the dermis of
the skin immediately under the epidermis, perceives light touches. It has a high
sensitivity (low threshold).
2._______________________ respond to faint vibrations and a deep motionless
touch. Because of the small perceptual field, detailed information is given.
3._________________ can detect temperature, mechanical stimuli (touch, pressure,
stretching) or danger (nociception).
4.____________________________, or lamellar corpuscle, is an encapsulated
mechanoreceptor formed by processes of epithelial cells that come into contact with
glial cells of the nerve process.
Task № 2
Label the image about the skin receptors:
Lamellated corpuscle (Pacinian corpuscle), free nerve endings, root hair plexus,
tactile corpuscle (meissner’s corpuscle), root hair plexus, merkel cell (Tactile discs)
