Cell Organelles
Mitochondria
Mitochondria are pleiomorphic organelles whose main function is to produce energy through oxidative phosphorylation.
This slide is of amphibian skin, which plays an
important role in osmoregulation. Why would we find mitochondria here?
Meosthelium
This slide has been silver stained to show the plasma membrane
Golgi
This ganglion preparation has been prepared using a classical procedure developed by Camillo Golgi in the
late 1800's
Notice that the nuclear components have been extracted during the procedure (white holes in cells)
Numerous Golgi complexes can be found throughout the neuron cell bodies
Cell Surface Specializations
Jejunum
the microvilli the makeup the brush border in these intestinal cell contains extensive actin network
Trachea
Cilia contain a microtubule array similar to that of flagella.
Nissl Bodies
This section of brain tissue has been stained to show the rough endoplasmic reticulum (aka Nissl Bodies)
Can be found in the cell bodies of various neurons
Rough endoplasmic reticulum is abundant in cells involved in protein synthesis for secretion, incorporation into membranes, or packaging into vesicles.
Secretory vesicles
The zymogen granules in these pancreatic acinar cells are packed with digestive enzymes like lipase and trypsin which are activated once they reach the small intestine. They are easily visible with a basic H & E prep.
