TISSUE TYPES

TISSUE TYPES

1. NERVOUS

   • MUSCLE
     • EPITHELIAL
       • Simple columnar
         • Function: protection, secretion, absorption
         • Location: lining of digestive tract and uterus
       • Stratified squamous
         • Location: lining air passages like the trachea and tubes of the reproductive system.
         • Function: protection
       • Transitional
         • Function: forms barriers to block diffusion
         • Location: urinary bladder
       • Simple cuboidal
         • Function: secretion and absorption
         • Location: lining of kidney tubules, ducts of glands, covering surface of ovaries
       • SIMPLE SQUAMOUS
         • Function: diffusion and fibration
         • Location: found in air sacs of lungs
       • Pseudostradified
         • Function: secretion and cilia-aided movement
         • Location: lining air passages like the trachea and tubes of the reproductive system.
     • CONNECTIVE
       • Bone
         • Functions: protection/ support, quick-healing
         • Locations: all over the body
       • Blood
         • Functions: transports oxygen and carbon dioxide, maintains body temp. controls pH, removes toxins from body
         • Locations: inside blood vessels, within the chambers of the heart
       • Elastic
         • Functions: allows respiratory organs to recoil after inhalation and helps push blood
       • Regular
         • Functions: forms ligaments and tendons, pulls fibers in direction its pullings
         • Locations: found in the tendons and ligaments
       • Reticular
         • Functions: supports walls of certain internal organs, and allows the liver to not collapse in on themselves.
         • Locations: found in the kidney, spleen, lymph nodes, and bone marrow
       • Irregular
         • Functions: holds skin on and allows it to stretch and reflects the direction of the pulling forces to which it is exposed
         • Locations: Internal to skin, around muscles and organs
       • Cartilage
         • Functions: support, frameworks, attachments
         • Locations: found in joints between bones, elbows, knees, and ankles
       • Adipose
         • Functions: provides fuel and insulation, cushions joints and some organs and forms tissue beneath the skin
         • Locations: Under the skin, around heart, kidneys, and nerve tissue
     • Cardiac. Function. Function: pumps blood throughout the body. Location: found in the heart and makes up bulk of the hearts mass
     • Smooth. Function: changes the volume of the organ they surround, and contracts to push food throughout the body. Location: found in the walls of hollow organs
     • skeletal. Function: moves bones/body. Location: muscles attached to the skeleton
   • Functions: sensory input, integration, control of muscles, homeostasis, and mental activity
   • Locations: found in nerves throughout the body, organs at nervous system, brain and spinal cord
