Tissues

• Epitherial (epithelium) tissue:

  • covering or lining tissue, cells very close together
  • function: secretion and protection
  • location: outer layer of skin and organs such as kidneys, heart, intestines etc
  • examples: blood vessles, lining stomach, nose, tounge
• Connective tissue:

  • cells seperated by non-cellular matirial called matrix (can be hard or liquid)
  • Fuction: support, holds body parts together
  • Location: in between other tissues in all parts of the body
  • Examples: loose or dense CT, adipose tissue, cartilige, bone, blood
• Skeletal muscular tissue:

  • attached to bones, are voluntary muscles
  • Function: contract to produce movement
  • Location: attached to bones via tendons
  • Examples: tongue, diaphram, eye socket, upper oesophagus
• Smooth muscular tissue:

  • involantary, can't contract voluntaraly
  • no striations (smooth)
  • Fuction: help with digestion and nutrience collection
  • Location: in walls of viceral organs (exept heart)
  • Examples: liver, pancreas, intestines
• Cardiac muscular tissue:

  • cannot be volantarily contracted
  • fuction: responsable for contracting (pumping) of the heart
  • location: thick middle layer of heart
  • example: heart wall
• Nervouse tissue:

  • specialised nerve cells called neurons
  • fuction: to carry messages around body
  • location: brain, spinal cord, nerves
  • examples: CNS, PNS
