Connective tissue

  1. 1. What can I see? ByRoss, James, Halen, Josh, Verver
  2. 2. Epithelial Tissue By James
  3. 3. Simple Squamous• Consists of only one layer of flat, scale-like cells.• Microscopic air sacs of the lungs, for example, are composed of this kind of tissue.
  4. 4. Stratified Squamous• Characterized by multiple layers of cells with typical flattened squamous cells.
  5. 5. Transitional• Is a stratified tissue typically found in body areas, such as the wall of the urinary bladder, that are subjected to stress and tension changes
  6. 6. Simple Columnar• Composes the surface of the mucous membrane that lines the stomach, uterus, uterine tubes, and parts of the urinary tract
  7. 7. Stratified Columnar• Has multiple layers of columnar cells, only the most superficial cells are truly columnar in appearance
  8. 8. Psuedostratified• Found lining the air passages of the respiratory system and segments of the male reproductive system such as the urethra
  9. 9. Simple Cuboidal• Composed of one layer of cuboidal cells resting on a basement membrane
  10. 10. Stratified Cuboidal• Two or more rows of low cuboidal cells are arranged randomly over a basement membrane
  11. 11. Glandular• Regardless of the secretory product produced, glandular activity depends on complex and highly regulated cellular activities requiring the expenditure of stored energy
  12. 12. Connective Tissue By Ross
  13. 13. Loose Ordinary Fibrous• The substance contains a large proportion of ground substances and lacks the massive fibrous reinforcement.
  14. 14. Adipose • Adipose is a major storage site for fat in the form of triglycerides.
  15. 15. Reticular • Forms the basis of such hematopoietic organs.
  16. 16. Dense Regular Fibrous• Contains densely packed collagen fibers that run in the same direction.
  17. 17. Dense Irregular Fibrous • Contains fibers that are not parallel to each other.
  18. 18. Bone Tissue• Tight and packed closely together. Compact to hold form and structure.
  19. 19. Hyaline Cartilage• Is pearly bluish, consistent, and considerable collagen.
  20. 20. Fibrocartilage • Helps with flexibility and toughness to maintain structure and form.
  21. 21. Elastic Cartilage• Contains fiber networks and collagen fibers.
  22. 22. Blood • Carries oxygen in to the tissue and takes out carbon dioxide to be released from the body.
  23. 23. MuscleBy Josh
  24. 24. Skeletal• Skeletal muscles are used to facilitate movement, by applying force to bones and joints; contraction. They generally contract voluntarily, although they can contract involuntarily.
  25. 25. Cardiac• This type of muscle is found solely in the walls of the heart. It has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control. However this type of muscle is highly specialised. It is under the control of the autonomic nervous system, however, even without a nervous imput contractions can occur due to cells called pacemaker cells. Cardiac muscle is highly resistant to fatigue due to the presence of a large number of mitochondria, myoglobin and a good blood supply allowing continuous aerobic metabolism.
  26. 26. Smooth• Smooth muscles are found in the hollow parts of the body. This would be in places like the stomach, intestines, blood vessels and the bladder. Smooth muscles are arranged in layers with the fibers in each layer running in a different direction. This makes the muscle contract in all directions. A smooth muscle is an involuntary muscle. This means that you cannot consciously control this muscle. These muscles are under the control of autonomic nervous system. This system controls many systems without us being aware of them.
  27. 27. NervousBy Halen
  28. 28. Nervous Tissue• Is the 4th basic tissue in the body.• It is organized into 2 systems, the central nervous system and the peripheral nervous system.• The peripheral system sends impulses to the central nervous system.• The basic cell of nervous tissue is the neuron.("")
