These are the Anatomical Society's arms, from the photo of the LPs on their website.
According to their website :
"The design alludes to the professions of members of the Anatomical Society who comprise medical practitioners, dentists, vets, scientists and artists.
"The frets in the Arms represent neural cells and the roundels within them, stem cells (for the scientists).
"A chevron is one of a series of bones on the ventral side of the tail in many reptiles and some mammals.
"The lion, the king of beasts (for the vets), in the Crest and in the Badge supports a Rod of Aesculapius (for the medical practitioners) and rests its paw on a skull (with teeth for the dentists).
"The Supporters are a male écorché and a female nude (for the artists). The motto ‘ex conformatione usus’ means ‘from structure comes function’."
The use of the fretty pattern to represent neural cells contrasts somewhat with Lord Lyon's use of "a human neuron Or" in the Rhetorical Company's arms ( viewtopic.php?f=7&t=955
