1. Loose
   1. Areolar

      Annotations:

      • forms membranes between organs and binds them together
   2. Adipose

      Annotations:

      • Stores fat, cushions, and insulates
   3. Reticular

      Annotations:

      • thin branched reticular fibers that support the walls of the liver and the spleen
2. Dense
   1. Dense Regular

      Annotations:

      • strong collagen fibers that bind structures as parts of tendons and ligaments
   2. Dense irregular

      Annotations:

      • thicker, randomly distributed collagen fibers and is found in the dermis
   3. Elastic

      Annotations:

      • elastic fibers that make up hollow internal organs like the lungs and blood vessels
3. Specialized
   1. Cartilage

      Annotations:

      • provides support Consists of fibers and a gel-like substances Lacks a direct blood supply, so it is slow to heal Found at the ends of various bones; in the ear; in the larynx; and in the pads between the bones of the spinal column, pelvic girdle, and knees
   2. Bone

      Annotations:

      • matrix consists of mineral salts and collagen, heals rapidly, compact and spongy bone
   3. Blood

      Annotations:

      • Composed of cells suspended in fluid, produced in the tissue of hollow parts of certain bones

1. Shape
   1. Cuboidal
   2. Columnar
   3. Squamous
2. Number of Cell Layers
   1. Stratified
   2. Simple
   3. Pseudostratiied

      Annotations:

      • only columnar cells can be pseudo stratified 
   4. Transitional

Annotations:

• function is movement attached to bones, in the walls of hollow internal organs, heart able to contract in response to stimuli

1. Skeletal

   Annotations:

   • contains striations long cellsresponsible movement of body parts, facial expressions, writing, talking, singing, chewing, swallowing, and breathingvoluntaryattached to bones
2. Smooth

   Annotations:

   • contains no striations short cells multinucleate involuntary
3. Cardiac

   Annotations:

   • found in the heart striated, branched, and joined end to end one nucleus  intercellular junctions called intercalated disc involuntary  can function without nervous simulation

Annotations:

• conduct impulses for coordination, regulation, and perception found in brain, spinal cord, nervescells communicate with each other and other body parts

1. Neurons

   Annotations:

   • dendrites transmit electrical signals to axons function is to coordinate, regulate, and integrate
2. Neuroglia

   Annotations:

   • supporting cells of the nervous tissue carryout phagocytosis some are involved in cell to cell communication
