Meaning of the word laminae

Question

Can you tell me the meaning of the word "laminae"? I have found this word in a book about the spinal cord, The book also uses the word "lamina", but this word means "láminas", I think. The specific topic is about the architectural organization of the spinal cord made by Rexed, that´s why lots of neuroanatomists call it: the Rexed lamination.

As the other say, layers of specialized tissue, organized tissue, see Margherites illustration. - annierats, May 25, 2013

Answer 1

Hi luisssito,

I don't know if this will help you, but In the horse, the laminae is the portion inside the hoof that connects the outer shell to the sensitive structures that are much deeper inside.

In this picture, the right half of the outer part of the hoof is shown peeled up. The red part is the laminae.

Thanks, Margherite! - luisssito, May 25, 2013

Quite right, hence laminitis, the inflammation of the laminae, socommon in fat ponies. - annierats, May 25, 2013

Answer 2

I don´t have specific spinal knowledge, but in general, lamina and the plural, laminae, are from latin and mean layers, but can also mean linings in some technical fields, including micro-chips on the micro-level, and layers of the earths surface on a macro level. Como láminas o capas. Spinal specific, I can´t say, but a quick poke around diagrams makes me think is is the tissue lining the spinal cord that helps form a conduit for the central nerve trunk. We need a medical person here to know for sure. I only know about fingers, ribs, and shoulders (the things I´ve already broken)

Thanks, rogspax, your answer is very helpful! - luisssito, May 25, 2013

Answer 3

Lamina (f. sing) is indeed Latin in origin, and means "layer", whether of wood, metal, or anything else. Some form of it appears in almost all the "European" languages, including English. The interesting aspect is that the Romans (used generically, that is those who lived under the empire, including Greeks) had ways of layering metal that are still not understood, and cannot be duplicated. The late empire coinage, for example, apparently without any sort of electroplating, has silver layers over copper or bronze, and no one is sure how they did it. Also the metal used in Roman swords, as it turns outs, is, a little like that of the Japanese masters, stronger and longer lasting than modern attempts to duplicate it. Some of this may (or may not) have to do with very sophisticated layering techniques that the moderns are just getting hints of.

Are you talking about the history of the languages? :) - luisssito, May 25, 2013

Thanks, anyway! - luisssito, May 25, 2013
