Histology look-a-like #46
Hair follicles (in the dermis) v A meteor shower (in space)
A look-a-like that is out of this world and craters to histologists at all levels of expertise. Amateurs to your left and meteorite.
Don’t you think armageddon better at finding these look-a-likes?
Anyway, if this post has left a deep impact, don’t forget to leave a comet below!

Prostatic concretion v A storm on Saturn
If I was ever asked which planet of our solar system reminded me of the histology of the prostate gland, my natural instincts would of course tend towards Uranus.
That is until…
…I saw these amazing pictures of Saturn sent back to Earth by the Cassini spacecraft. They show a 2000 kilometers (1200 miles) diameter hurricane raging over Saturn’s north pole.

Fibrocartilage from an intervertebral disc (IVD) v A Mars Sky
The purple sky ‘trails’ are Type I collagen fibers within the annulus fibrosus. These resist the tensile forces applied to a disc during movement of the vertebral column.
The red ‘comets’ are chondrocytes. Mature cartilage cells trapped within lacunae.
The orange-red material at the lower aspect of the image is the core of the IVD – termed the nucleus pulposus.This forms a gel that is composed of the proteoglycan aggrecan. Aggrecan is hydrophilic and draws water into this region of the IVD. Water is difficult to compress, therefore this central region is specialized for resisiting compressive forces applied to the vertebral column.
You can see that the histological organization of fibers and aggrecan molecules in the IVD allows it to function in resisting both the tensile and compressive forces applied to the vertebral column every single day.
Simply A-mars-ing,

Pacinian corpuscles v Xibalba (from the movie “The Fountain”)
Pacinian corpuscles are one type of mechanoreceptor found in the body. Located in the skin they detect pressure and vibration.
This is in complete contrast however to the Mayan underworld ruled by death Gods and their demon buddies. Depicted here in the movie The Fountain as the Orion nebula.
According to The Sacred Book of the Maya: The Great Classic of Central American Spirituality, 2007, (translated by Allen J. Christenson), the residents of this terrifying place are the Lords of Xibalba, namely, Hun-Came (One Death) and Vucub-Came (Seven Death). Their cronies are demons who work in pairs to oversee various forms of human suffering .
Xiquiripat (Flying Scab) and Cuchumaquic (Gathered Blood) like to sicken people’s blood;
Ahalpuh (Pus Demon) and Ahalgana (Jaundice Demon) make it thier mission to make people’s bodies to swell up;
Chamiabac (Bone Staff) and Chamiaholom (Skull Staff) do their bit for the environment by turning dead bodies into skeletons;
Ahalmez (Sweepings Demon) and Ahaltocob (Stabbing Demon) promote health and safety in our homes by hiding in the unswept areas of people’s houses and stabbing them to death;
Xic (Wing) and Patan (Packstrap) have the very specific job of causing people to die coughing up blood while out walking on roads.
Perhaps even more terrifying is while editing this image (submitted by daydreamingwanderer – thanks ddw – this is awesome). The width of both images randomly came to span 666 pixels. Read into that what you will, but I couldn’t bring myself to change it. Somehow it seemed so fitting.
Moral of this story: There is a reason why your parents pressure (there’s the Pacininan link) you into cleaning your room when you are a kid. It seriously is for your own safety.
Thanks again to daydreamingwanderer for this fantastic submission!
