English to Spanish Medical Medical (general) Bone physiology

To tell you the truth, I'm translating from Portuguese to Spanish a presentation on Ca & P metabolism - NOT from English. The only option I can think of at present is transporting it to English (no entries for the expression in Proz from Portuguese>Spanish or English>Spanish).
The text says...in Portuguese "Os ossos são tecidos que contêm poucas células e muita matriz. A matriz óssea é constituída de colágeno e outras proteínas, impregnada por cristais de vários minerais (mineralizada)".
I inferred that this was a rough translation from English that would read something like this (I'm leaving out the previous sentence): "Bone matrix consists of collagen and other proteins, impregnated with crystals of several minerals (mineralized).
Here's an example I found online:
Dentine: supports enamel and acts as the skeleton of the tooth; hard material of collagen fibrils, impregnated with crystals of calcium salts; penetrated from the pulp side by dentinal tubules enclosing long, thin processes of odontoblasts, whose bodies lie outside the dentine at the pulp.
Now...what I need is the translation into Spanish (Latin American, preferrably).
Thank you in advance! I know there are many of you out there who are trilingual. Best regards!
