Connective Tissue
Functions
-
-
Medium for exchange of nutrients, oxygens and waste products between other tissues
-
-
-
-
-
-
- Spindle-shaped, Smaller
than active fibroblasts
- Fewer processes
- Small amount of rER
- Smaller, darker and elongated
nucleus
-
- Abundant and irregularly branched cytoplasm
- Large ovoid pale-staining nucleus
- Rich in rER, well developed Golgi complex
-
- Features of both fibroblast and
smooth muscle
- Numerous in wound healing
- Morphologic characteristics of fibroblast
- Contain increased amounts of actin & myosin
-Behave like smooth muscle
- Structure : Narrow rim of cytoplasm,
flattened and eccentric nucleus and appear
as empty cells
- Lipid droplet
- Function : Store fats and produce heat
- Location : Throughout loose connective tissue
- Structure : Large, ovoid cells with spherical nucleus, cytoplasm filled with large basophilic secretory granules
- Location: Not easily identified
- Function : Store chemical mediators of inflammatory response
-Substance release: Histamin
-
-
-
- Migrate from blood vessels
- Do not return to blood exc lymphocytes
- Spherical cells
- Dense staining nuclei
- Natural killer cells
- Migrated in response to specific stimuli
- Derived from b- lympocytes
- Function :Synthesis antibodies
- Location : Loose connective tissue associated with epithelial tissue
- Structure: Large ovoid cells with eccentric and deeply stained nucleus (clock-face appearance)
- Flexible and have high tensile strength
- Stain with eosin
- Appear as wavy structures of variable width and intermediate length
- Appear as bundles of fine, thread-like subunits-collagen fibrils
- Very strong & great resistance
to tensile strength
- Skin, tendons, ligaments and bone
- Provide resistance to pressure
- Hyaline and elastic cartilage
- Thin and branching reticular fibers
- Forms meshwork in liver, lymph node,
spleen and hematopoietic organs
- Basal lamina of basement membrane
- Mainly type III collagen
- Arranged in a mesh-like pattern or network
- Abundant in liver, lymph node, spleen and hematopoietic organs
- Support capillaries, nerves and muscle cells
- Only visible when stained with SILVER STAIN
- Thinner than collagen fibers
- Arranged in branching pattern to form 3D network
- Interwoven with collagen fibers to limit distensibility of tissue and prevent tearing from excessive stretching
- Stain with eosin but not well
- Ligamentum flava of vertebral column, vocal folds, elastic arteries
- Viscous, clear substance that has a slippery feel
- High water content
- Fills the space between cells and fibers, lubricant and barrier to penetration of invaders
- Forms glycosaminoglycans, proteoglycans and multi adhesive glycoproteins
- Areolar
- Thin fibers and relatively sparse
- Ground substance abundant
- Beneath epithelia that covers body surfaces and line internal surfaces of the body
- Abundance of fibers that are arranged in bundles oriented in various direction and few cells
- Little ground substance
- Present in submucosa of hollow organs and reticular layer of the dermis
- Collagen bundles are arranged according
to a definite pattern
- eg : tendons, ligaments , aponeuroses
- Unilocular
- Hypodermis
- Predominet in adult
- The distribution and density are determined by age and sex
- Insulating function in skin
- Richly vascularzed
- Polyhedral or spherical
- Thin ring of cytoplasm surrounding the vacuole left by the dissolved lipid droplet
- Eccentric and flattened nuclei
- Moltilocular cells
- Location: Human embryo, newborn and certain areas
- Produce heat and protect newborn against cold
- Polygoal and smaller than white
- Cytoplasm -numerous lipid droplets and mitochondria
- Nucleus - eccentric but not flattened
