Cardiac and skeletal muscles1
Cardiac and
 skeletal is muscles
Cardiac muscles: a type of
involuntary
Striated muscle found in the walls of the
heart specially in the myocardium.



                            Myocardium
Cardiac muscles
Main types of cells:
- Myocardial cells: Make up the artrium (the chamber in
  which blood enters the heart) and ventrical (where blood is
  pumped out of the heart) of the heart. These cells are
  necessary to the beating of the heart.
Cardiac muscles
Main types of cells:                   Heart Cell
-     Electrical cells:
      -They carry the impulses
that are responsible for the beating
of the heart.
      - Responsible for several
functions, like generate and send
out electrical impulses and receive
and respond to electrical impulses
from the brain.
Cardiac muscles
Structure of cardiac
tissue
 - Cardiac muscle fibers are
striated, branched, and have a
single central nucleus. These
cells are attached at their ends to
the fibres by thick plasma
membranes.
Cardiac muscles
- Structure of Cardiac Tissue
Cardiac muscles
- The types of tissue:
- Endocardium
- Myocardium
- Epicardium
Cardiac muscles
• Endocardium
  The endocardium is the smooth layer of tissue that
 lines the walls of the heart. It has a shiny surface that
 allows blood to flow freely.




  Endocardium
Cardiac muscles
• Myocardium
 The myocardium is the thick, muscular, middle layer of
 the heart. This layer is responsible for contracting the
 heart and sending blood to the body tissues.




                                 Myocardium
Cardiac muscles
• Epicardium
 The epicardium or outer layer is a thin layer that serves to
 support in place and protect the heart.
Cardiac muscles
Organ:
We can find cardiac muscles tissues in the heart.
Cardiac muscle
- The functions:
  Pumping of blood through the heart:
  Alternate contraction and relaxation of cardiac
  muscle pumps
Cardiac muscles
• Infectious Diseases of the Heart
 - Some infectious diseases cause inflammation of
  one of the cardiac tissue layers, resulting in
  permanent heart damage. A virus or type of
  bacteria typically causes these conditions.
Skeletal muscle
          tissue
Skeletal muscle tissue:
It’s a type of striated muscle that allows to do
voluntary physical movements of all types.
Skeletal
              muscle
Main types of cells:
Skeletal tissue is mainly made up of myocites.
The cells that make up skeletal muscle tissue are

              Tissue
long and fibrous.




      Myocyte
Skeletalmuscle
         tissue
Structure of skeletal tissue:
Skeletal muscle
We can find
            tissue
skeletal muscle
tissue in the
muscular
system.
Skeletal muscle
         tissue
Functions of skeletal tissue:
- Skeletal tissue work in pairs to coordinate the
movements of the limbs, trunk, etc.
- They are directly involved in breathing.
Skeletal muscle
        tissue
Diseases of the
skeletal muscle:
Fibromyalgia is a
disorder that causes
muscle pain and fatigue.
People with fibromyalgia
have "tender
points" in the body.
                           Tender points
Cardiac and skeletal muscle
              tissue
• Questions:
1. What is the main difference between cardiac and
   skeletal tissues?
- Cardiac tissues are involuntary
   and skeletal tissue is voluntary.
1. What is the main function of the cardiac muscle
   tissue?
- Pumping blood through the
   heart.
