Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen.

Coloured scanning electron micrograph (SEM) of a red blood cell squeezing out of a torn capillary. A capillary is the smallest type of blood vessel, often only just large enough for red blood cells to pass through.

Brain and spinal cord with the meninges still intact. Viewed posteriorly

scienceyoucanlove: “ Brain and spinal cord with dural membranes (meninges) still intact, held aloft and viewed posteriorly. Below the skull and around the spinel cord are three special coverings called the meninges. You may have heard of the illness.

Photographs of the brains of different species

emt-monster: “ asapscience: “ A comparative look at the brain sizes of different species. ” Brain size is interesting if you compare it to body size. The larger the body, the more brain is needed to.

Medical illustration of Pseudomonas aeruginosa.

pseudomonas aeruginosa is contracted through warm moist environments. It can be contracted through tubs, soil, contact with an infected person, and through hospitalization over a week.

In this picture you can see reasonably well how closely adherent the dura is to both the brain and the skull (you can see how close it is to the skull near the bottom of the picture).

“ A brain autopsy demonstrating signs of meningitis. The forceps (center) are retracting the dura mater (white). Underneath the dura mater are the leptomeninges, which appear to be edematous and have.
