× Our skin is the largest sensor; it can sense texture, pressure, warmth, coldness and pain.
✓ Our skin is the largest sensor; it can sense texture, pressure, warmth, cold and pain.
× (To be accurate, Merkel's discs exist just between epidermis and dermis.)
✓ (To be accurate, Merkel's discs exist just between the epidermis and dermis.)
× In the dermis, we have Meissner's corpuscles (changing in texture and slow vibrations receptors), Ruffini's corpuscles (skin stretch receptors), Pacinian corpuscles (deep pressure, fast vibrations receptors) and Krause's corpuscle (coldness, pressure and texture receptors).

× Additionally, nerves ending called palisade ending cling around hair follicle and sense the movement of hair.
✓ Additionally, nerves ending called palisade ending wrap around hair follicles and sense the movement of the hair.
× The more receptors exist, the more sensitive the skin is.
✓ The more receptors the are, the more sensitive the skin is.
× We can know how sensitive the skin is by using two needles; sting two points simultaneously and test the minimize distance of two needles that you can notice.
✓ We can know how sensitive the skin is by using two needles; by poking two points simultaneously and test the minimal distance between the two needles that you can notice.
× Tongue and fingertip is the most sensitive; we can notice only one millimeter space.
✓ The tongue and fingertips are the most sensitive; we can distinguish a one millimeter distance.
× On the other hand, back and neck is the most insensitive; we cannot notice even five centimeter space.
✓ On the other hand, the back and neck are the least sensitive; we cannot distinguish even a five centimeter space.
× Referred pain is a skin pain caused by visceral pain.
✓ Referred pain is a type of pain caused by visceral pain.
× Very strong visceral pain can stimulate nearby nerve in the spine and it causes skin pain.
✓ Very strong visceral pain can stimulate nearby nerves in the spine and causes skin pain.
