15. The most significant nerve sensations in the
human body are:
 The sensation of touch: the corpuscles
responsible for such sensation are called
Meissners and Merkels corpuscles.
 The sensation of pain: this is transported
by the nerve endings in the skin.
 The sensation of heat: this is the
responsibility of Ruffini cylinders
corpuscles.

19.  2- Burns of second degree:
epidermis and dermis are injured.
 In such a case, a
detachment occurs between
epidermis and dermis, causing
the collection of secretions
between these two layers (Figure
2).

20.  The injured person suffers from severe
pain, and excessive increase of pain
sensation, due to irritation of exposed
nerve ending particularly after the
outburst of blisters.
 The skin starts to heal within 14 days as a
result of the process of renovation and
inversion under the skin.

21.  3- Burns of third degree: the whole skin
thickness is burned and perhaps the injury
may reach the muscles or the bone.
 The skin loses elasticity and becomes
rough and dry.
 In this case, the injured person do not feel
much pain, as nerve endings have been
damaged almost completely due to
burning (Figure 3).
