life sciences: animal tissue

  1. 1. AnimalTissues Prepared by: MOKWENA CATHY BUITUMELO
  2. 2. AnimalTissues • Cells form groups to produce specialized tissues that function together in a specific activity • Classification:  Epithelial tissues  Connective tissues  Muscular tissue  Nervous tissues
  3. 3. Connective Tissue Types of ConnectiveTissue  Loose (Areolar) ConnectiveTissue  Adipose  Blood  Fibrous ConnectiveTissue  Cartilage  Bone
  4. 4. Loose Connective Tissue  Contain fibers and fibroblasts  Fibroblasts produce and secrete the fibers.  Loosely arranged in a semi fluid substance.  Acts as the framework for epithelium.  Forms a protective layer over muscle, nerves, and blood vessels. Elastic Fibers Collagen Fibers Fibroblast nuclei
  5. 5. Adipose Tissue  Adipose cells contain a large vacuole which in the live cell contains lipids.  Cell nucleus and cytoplasm are pushed out to edge of cell membrane.  Adipose tissue has enlarged fibroblasts storing fats and reduced intracellular matrix.  Adipose tissue facilitates energy storage and insulation.
  6. 6. Blood connective tissue  Red blood cells (erythrocytes) carry oxygen.  White blood cells (leukocytes) function in the immune system.  Plasma transports dissolved glucose, wastes, carbon dioxide and hormones, as well as regulating the water balance for the blood cells.  Platelets are cell fragments that function in blood clotting.
  7. 7. Blood connective tissue Blood vessel Red blood cells White blood cells Plasma Platelets
  8. 8. Fibrous Connective Tissue  Many fibers of collagen occurs in  Tendons, connect muscle to bone.  Ligaments connect bone to bone at a joint.  Contains elastic fibers that allow movement at joints
  9. 9. Muscular tissues
  10. 10. Smooth muscle • These have long cells which have single nucleus. • The cells of this muscle is spindle in shape. • They are also called unstrained because we can not control them
  11. 11. Cardiac muscle • It is the muscle which is present in heart. • These muscle are also called involuntary muscle. • These muscle have cylindrical &branched muscle.
  12. 12. Skeletal (striated) Muscle  These cells function in conjunction with the skeletal system for voluntary muscle movements.  Located in muscles that attach to bones.  Long, cylindrical cells are striated.  Cells are bundled closely together in parallel arrays.
  13. 13. Characteristics Skeletal Smooth Cardiac Location Attached to skeleton Walls of internal organs Walls of heart Cross-striations Present Absent Present Shape of fibers Cylindrical Spindle-shaped Branched Number of nuclei Many or multinucleate One or uninucleate One or uninucleate Position of nuclei Peripheral Center Center Type of control Voluntary Involuntary Involuntary Speed of contraction Most rapid slowest Intermediate
  14. 14. NervousTissue
  15. 15. Nerve (close-up view) 1. Endometrium 2. Epineurium 3. Axon 4. Schwann cell nucleus 5. Epineurium
  16. 16. 3. Axon (nerve fiber) 1. Myelin sheath 2. Neurilemma 3. Node of Ranvier 4. Schwann cell 5. Axon
  17. 17. Nervous tissues • Neuron • Cell body • Processes a. Axon b. Dendrites
  18. 18. Nervous tissue consists of neurons, which are the cells that conduct signals, and supporting neuroglia cells such as microglial cells, astrocytes and oligodendrocytes
  19. 19. Flattened, cuboidal, columnar Irregular or round Elongated Cell appendages branched Single  multilayered Scattered in matrix In sheets or bundles Isolated or networked Body covering or lining organs or cavities Supports other organs Lining internal organs, make skeletal muscles Concentrated in brain and spinal cord + all over the body Cilia, microvilli - - - Basement membrane Varied – protein fibers + liquid, gelatinous, firm to calcified - - Minimal Extensive Absent Absent No direct blood supply, except for glands Cartilage has no blood supply Can generate electrical signals, force and movement Can generate electrical signal
  20. 20. Cartilage • Chondrocytes (cartilage cells) • Avascular, lacking blood vessels ---- does not possess the regenerative capacity • contains a gelatinous ground substance called chondroitin sulphate • Embedded within the GS are collagen & elastic fibers • Together (chondroitin sulphate + fibers) -- flexible, yet very durable and also resistant to compression forces • produced by chondroblasts through the process chondrification • Types a. Hyaline cartilage – most common type; in fatal skeleton, cartilaginous fishes b. Elastic cartilage c. Fibrocartilage
