My favorite Stephen Gammell illustrations from ‘Scary Stories to Tell in the Dark’.

Stephen Gammell was probably my biggest inspiration growing up, one of them anyway. 




How to construct a blood vessel!

Making sense of the histology of arteries and veins


If you like words, the full post about How to classify blood vessels (including this image) visit the ihearthisto.com post here

Or you can just sit back, watch and realize that you just learned about the tunics of a vessel. That’s histology folks!

Have fun,



Bovine Pulmonary Artery Endothelial Cell

Mouse monoclonal anti-α-tubulin antibodies were localized to the microtubules in this fixed bovine pulmonary artery endothelial cell (BPAEC) and subsequently visualized using goat anti-mouse IgG antibodies conjugated to Alexa Fluor® 350 dye (blue). Next, F-actin was labeled with phalloidin conjugated to Alexa Fluor® 594 dye (red). Finally, the cell was incubated with wheat germ agglutinin conjugated to Alexa Fluor® 488 (green) to stain components of the endosomal pathways. This superimposed and pseudocolored photomicrograph was acquired sequentially using bandpass filter sets appropriate for DAPI, the Texas Red® dye and fluorescein, respectively.

Satisfy your sweet tooth with some histology* blood smear cookies!

*also available in other scientific flavors

Multi-talented biological anthropologist/blogger/baker/stay-at-home mom Isla Humble made these mouth watering blood smear cookies.

If histology isn’t to your taste however why not try out some of her other scientific flavors including:

  • Pathologist
  • Test tube
  • SDS gel electrophoresis
  • Atom
  • Drosophila melanogaster
  • Bacteria colony


If you aren’t following her cooking blog already (seriously?), pay her a visit right now here, pick up some tips, marvel at her creations, become inspired and then just go ahead and bake me some histology related goodies to eat and display on my blog. Please and thanks ;-)

The aortic arch in a child.

This amazing picture shows the arch of the aorta, a part of the aorta between ascending aorta and thoracic aorta, with its three major branches: from the left to the right they are the brachiocephalic trunk, which supplies the right side of the head and neck, as well as the right arm and chest wall, the left common carotid artery, and the left subclavian artery. The latter two together supply the left side of the same regions.

Aorta originates from left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries) and it distributes oxygenated blood to all parts of the body through the systemic circulation.

The aortic arch contains baroreceptors and chemoreceptors that relay information concerning blood pressure and blood pH and carbon dioxide levels to the medulla oblongata of the brain. This information is processed by the brain and the autonomic nervous system mediates the homeostatic responses.
