The Common Integuments and Skin Anatomy

COMMON Integuments
The term common integument refers to study the
skin with  its covering of hair and variety of skin
glands as well as more specialized parts such as
claws, hoof and horns.
The skin
The skin completely encloses the body and blends
with the mucous membranes at the various natural
openings.
Function of the skin 
protects the body from tear and invasion by
microorganisms
play an important part in thermoregulation
Impermeable to water and prevent the body
from drying out .
Certain lipid substances can penetrate and
used as vehicles for administration the drug .
The color of the skin
Depends partly on the present of pigmented granules
in certain component cells. These protect against
ultraviolet radiation
The structure of the skin
The skin is composed of two parts ,a superficial
epithelium (epidermis) and a tough fibrous layer
(dermis ) . The epidermis is continuously renewed, by
cell division in the deepest layer followed by migration
of daughter cells toward the surface . The dermis; it
contains nerve endings, sweat glands, oil glands, and
hair follicles. Under these two skin layers is a fatty layer
of subcutaneous tissue (the word subcutaneous means
"under the skin").
 
NAILS , CALWS AND HOOFS
These Structures closing the distal phalanx

are basically similar , and serve primarily  to
protect the underlying tissues .
The nail(

 of primates  grow from the
epidermis , covering a curved fold of dermis at its
base .
The claw(

 of carnivorous  can be likened

so has obtained  a sharp dorsal border
The hoof of horse
 is the horny covering of the
distal end of the digit. It is divide it for description
into three parts, termed the wall, sole, and frog.
Topographically
  The wall may be divided into
an anterior part or "toe" , lateral parts or
"quarters" and the angles or "heels"). It
presents two surfaces and two borders.  The
outer surface is convex from side to side and
slopes obliquely from edge.  The curve of the
wall is wider on the external than on the
internal side. The inferior or  ground surface
normally arched—and more strongly in the
hind than in the fore foot—but the curvature
is subject to wide variation.
The wall of horse hoofs in addition  strongly
curved ,  the sides is sharply inflected(

)  to form so called bars . The space
between the bars is occupied by the frog , the
part of footpad that makes contact with the
ground . The sole horns that fills the ground
surfaces between the wall and frog meet the
wall at a junction  known as the white line .
The white line marks the border between the
sensitive and insensitive sole. It serves as a
guide to show where nails should be driven
when shoeing the horse
 
 
The wall grows distally from the epidermis
regions of the dermis; the combination of
horn types gives the tissue a finely striated
appearance. The (laminar) epidermis deep to
the wall  arranged as several hundred well
formed laminae that tightly interdigitate with
an equal number of dermal laminae  bonding
the wall to the underlying distal phalanx.

The common integuments encompass the skin, hairs, skin glands, claws, hooves, and horns, playing vital roles in protection, thermoregulation, and drug administration. The skin's structure consists of the epidermis and dermis layers, renewing continuously to maintain its functions. Additionally, nails, claws, and hoofs serve to protect underlying tissues. Explore the topographical features of the skin and its appendages for a comprehensive understanding.

  1. COMMON Integuments The term common integument refers to study the skin with its covering of hair and variety of skin glands as well as more specialized parts such as claws, hoof and horns. The skin The skin completely encloses the body and blends with the mucous membranes at the various natural openings.

  2. Function of the skin protects the body from tear and invasion by microorganisms play an important part in thermoregulation Impermeable to water and prevent the body from drying out . Certain lipid substances can penetrate and used as vehicles for administration the drug .

  3. The color of the skin Depends partly on the present of pigmented granules in certain component cells. These protect against ultraviolet radiation The structure of the skin The skin is composed of two parts ,a superficial epithelium (epidermis) and a tough fibrous layer (dermis ) . The epidermis is continuously renewed, by cell division in the deepest layer followed by migration of daughter cells toward the surface . The dermis; it contains nerve endings, sweat glands, oil glands, and hair follicles. Under these two skin layers is a fatty layer of subcutaneous tissue (the word subcutaneous means "under the skin").

  5. NAILS , CALWS AND HOOFS These Structures closing the distal phalanx ,they are basically similar , and serve primarily to protect the underlying tissues . The nail( ) of primates grow from the epidermis , covering a curved fold of dermis at its base . The claw( ) of carnivorous can be likened to a nail that has been laterally compressed and so has obtained a sharp dorsal border The hoof of horse is the horny covering of the distal end of the digit. It is divide it for description into three parts, termed the wall, sole, and frog.

  6. Topographically The wall may be divided into an anterior part or "toe" , lateral parts or "quarters" and the angles or "heels"). It presents two surfaces and two borders. The outer surface is convex from side to side and slopes obliquely from edge. The curve of the wall is wider on the external than on the internal side. The inferior or ground surface normally arched and more strongly in the hind than in the fore foot but the curvature is subject to wide variation.

  7. The wall of horse hoofs in addition strongly curved , the sides is sharply inflected( ) to form so called bars . The space between the bars is occupied by the frog , the part of footpad that makes contact with the ground . The sole horns that fills the ground surfaces between the wall and frog meet the wall at a junction known as the white line . The white line marks the border between the sensitive and insensitive sole. It serves as a guide to show where nails should be driven when shoeing the horse

  8. The wall grows distally from the epidermis regions of the dermis; the combination of horn types gives the tissue a finely striated appearance. The (laminar) epidermis deep to the wall arranged as several hundred well formed laminae that tightly interdigitate with an equal number of dermal laminae bonding the wall to the underlying distal phalanx.
