In focus: Your teeth are a sensory system

This week’s post is from Kelsey Stilson, a PhD student in biology at the University of Chicago, specialising in neurobiology and functional anatomy. It’s a post with teeth, in more ways than one! If you would like to write for Anatomy to You, get in touch via Facebook or Twitter. I study opossums. Specifically, I study…

In focus: The fabella, the forgotten knee bone

This week’s post is from Dr. Michael Bertaume, an “anthroengineer”– combining studies of anthropology and mechanical engineering perspectives. This post is about his team’s scientific paper just published here.

In focus: The mysterious extra ‘digits’ of pandas, moles and elephants

The biological ‘five finger rule’ is strikingly consistent throughout living tetrapod vertebrates. Humans and other primates, most carnivorous mammals, crocodiles, lizards and tortoises all typically possess the five digits (fingers and toes) characteristic of tetrapod limbs. It wasn’t always so – the ancient ancestors of the first vertebrates to walk on land, such as Ichthyostega and Acanthostega, had up to…

#FossilFriday: A four-legged snake from Brazil points to the origins of modern snakes

It sounds like a contradiction, but palaeontologists from the UK and Germany have discovered a snake with legs! This stunning fossil, found in Brazil, dates from the time of the dinosaurs in the early Cretaceous period, which began more than 145 million years ago. The new species, Tetrapodophis [meaning four-legged] amplectus, has the characteristic anatomical features of a snake,…

In Focus: Can golden moles hear the earth move with a Thor-like ‘hammer’?

The golden moles (Chrysochloridae) are a group of silky and rather endearing group of mammals resembling, but distinct from, the true moles (talpids). Indeed, they are more closely related to elephants and manatees than to moles, shrews, rodents or other seemingly similar animals. They share many features with moles, such as adaptations to burrowing, and inhabit…

Water molecule tracking reveals intricate muscle patterns in a tiny heart

The fibres of a mouse heart resemble a neat bird’s nest structure, but their specific orientations and interactions come together to drive blood around the body. The individual muscle strands were visualised using diffusion tensor imaging, which essentially tracks the movement of water molecules through single cells, revealing their position, size and shape. The pattern of…
