These line the Choroid Plexus, a layer of tissue that lines the inside of the ventricles of the The swollen tips of these cells secrete the cerebrospinal fluid which bathes the in glucose and proteins, and prevents it from collapsing under its own weight.
Adipose cells or adipocytes are specialized connective tissue for the storage of fat. The large adipocytes are held in place by strands of collagen fibers and a fine network of reticular fibers. A large capillary is seen near the cell surface.
Coloured SEM of a cultured cancer cell moving through a hole in a support film. Numerous pseudopodia, fillipodia and surface blebs can be seen and are characteristic of highly mobile cells which enable them to metastasise rapidly.
Human Body Ingredients via imaginaryfoundation: 'The average human has approximately 100 trillion cells and each cell is made of approximately 100 trillion atoms, each of which were originally created in the center of a star.' Here it is by mass: http:/
A cross section of a bundle of nerve fibers. Axons (orange) are wrapped in myelin (purple); an extension of the membrane of glial cells. Myelin has high lipid content, and acts to insulate the axons, causing them to transmit nerve impulses much faster.
It's pretty awesome to see an actual neuron and be able to identify it's components A neuron from the hippocampus at magnification. There are approximately 100 billion neurons in the human brain. Image by Dr. Carlo Sala, CNR Institute of Neuroscience
Very devious - The common cold virus, constantly mutates to avoid detection. Just how totally viruses can overcome a healthy host is seen when an infected human cell ruptures, releasing a stream of new viruses (blue) into the system.
