Scanning electron micrograph (SEM) depicting a Giardia lamblia protozoan undergoing binary fission, creating what appears to be a microscopic “heart.” This flagellated protozoan parasite inhabits and reproduces in the lumen of the small intestine and is responsible for the diarrheal infection giardiasis.

It looks cute but this little protozoan will give you terrible diarrhea. Scanning electron micrograph (SEM) depicting a Giardia lamblia protozoan undergoing binary fission, creating what appears to be a microscopic “heart.

Microscopic HUMAN egg. Color-enhanced. "The egg is coated with the zone pellicuda, a glycoprotein that protects the egg but also helps to trap and bind sperm. Two coronal cells are attached to the zone pellicuda."

This image is of a purple, colour-enhanced human egg sitting on a pin. The egg is coated with the zona pellicuda, a glycoprotein that protects the egg but also helps to trap and bind sperm. Two coronal cells are attached to the zona pellicuda.

Red blood cells trapped by fibrin threads, Macro

red blood cells trapped by fibrin threads Fibrinogen is an insoluble protein made by the liver and floats around in the blood. It is converted to fibrin by thrombin, a clotting enzyme, at bleeding sites.

MICROSCOPIC HAIRS IN INNER EAR:  Inner ear help divers (like the one in today's pic) know their up down orientation in water.  Sounds under water are magnified. When we hear sounds (whether under water or above) microscopic hairs in our inner ears vibrate.

Human Red and White Blood Cells Description: Coloured scanning electron micrograph (SEM) of human blood showing red and white cells. Magnification at an image size of 10 cm wide

Coloured scanning electron micrograph (SEM) of glomeruli (green) and blood vessels (pink) in the human kidney. Glomeruli are made up of a tight knot of blood capillaries covered in podocyte cells

Red blood cells exposed inside a torn venule. A venule is a very small blood vessel in the microcirculation that allows deoxygenated blood to return from the capillary beds to veins.

"Vesicles bursting out of a synapse" From now think of your mood swings as a colourful party in your brain with the synapses throwing confetti.

Nerve bundle. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through a bundle of myelinated nerve fibres. Myelin sheaths (yellow) can be seen surrounding the axons (blue). Perineurium (connective tissue, pink) surrounds the nerve bundle while endoneurium divides the individual fibres.
