General Characteristics of Muscle Tissue Powered By Docstoc
					     General Characteristics of
          Muscle Tissue
   Function
     movement

   Location
     attached to bones, in the walls

      of hollow organs, heart
   Distinguishing characteristics
     contractile
      General Characteristics of
           Muscle Tissue
   Fibers pull at the attached end
    to move body parts
   3 main types:
      Skeletal

      Smooth

      Cardiac
         Skeletal Muscle -
        Key Characteristics
   Most abundant type found in
    the body
   Striated
   Voluntary
   Long, nonbranching cylindrical
    cells
   Multiple nuclei along
    perimeters
      Skeletal Muscle -
    Locations in the Body
 Found around cartilage and
  bone
 Attach muscles to the

  skeleton
Skeletal muscle
          Cardiac Muscle -
         Key Characteristics
   Weak striations
   Involuntary
   Cylindrical, branching cells
   Have intercalated disks at end of
    cells
   Centrally located nuclei
   Once differentiated - does not go
    through mitosis (aka -
    reproduce)
         Cardiac Muscle -
       Locations in the Body
   Only found in the heart
Cardiac Muscle
               Smooth Muscle -
              Key Characteristics
   Involuntary
   Lack striations
   Single, centrally located nuclei
   Cells shorter than skeletal tissue and spindle
    shaped
   Used in the contraction of the bladder
   Peristalsis of the digestive system
   Constricts blood vessels
         Smooth Muscle -
       Locations in the Body
   Found in walls of visceral
    organs (stomach,
    esophagus, uterus)
Smooth Muscle
         General Characteristics of
             Nervous Tissue
   Function
       transmit impulses for
        coordination, regulation,
        integration, & sensory reception
   Location
       brain, spinal cord, nerves
   Distinguishing characteristics
       cells connect to each other &
        other body parts
    General Characteristics of
        Nervous Tissue
 Cells contain a single nuclei
 Cells are called neurons

 Highly branched

 May have a covering called
  myelin
 Cannot reproduce once

  differentiated
Neurons
Neurons in CNS
    Neurons in CNS
   Sense changes in the surroundings
   Transmit impulses along nerve
    fibers
   Coordinate, regulate, & integrate
    body functions
   Locations in the body
       Brain
       Spinal Cord
Neuroglial Cells
 Support and bind
  components of nervous
  tissue
 Phagocytosis

 Supply nutrients to neurons
