#collagen

• Albuminoid — Resembling albumin or possessing similar properties; an old term given to scleroproteins, a class of insoluble proteins with a structural and supportive role in the organism (such as keratin, collagen, or elastin), found in connective tissues, bones, nails, and hair strands.
• Anticollagenase — A biological substance, inhibitory enzyme, or cosmetic agent that blocks, neutralizes, or reduces the activity of collagenase (the enzyme responsible for breaking down collagen in tissues). In dermatology and advanced anti-aging cosmetics, anticolagenase substances are structurally utilized to protect the skin's extracellular matrix, maintaining its firmness and elasticity and preventing wrinkle formation.
• Aponeurosis — A graphical variant or scholarly anatomical term for an aponeurosis, denoting a fibrous, whitish, and pearly membrane composed of dense collagen bundles that serves as a protective investment for muscles or as a broad attachment structure fixing them to bones. Biomechanically, these fascial structures are essential for transmitting kinetic forces and maintaining anatomical posture.
• Aponeurosis — A wide, whitish, pearly, and extremely resistant fibrous membrane, composed of dense collagen bundles, that serves as a protective investment for muscles or as a structure attaching them to bones; a flattened tendon. Biomechanically, these fascial structures are essential for transmitting kinetic forces, maintaining anatomical posture, and defining muscular compartments within the body.
• Areolar — Belonging or relating to an areola, or exhibiting small structural spaces, networks, or cavities. In anatomy and histology, the term is fundamentally utilized to describe loose (areolar) connective tissue, characterized by a structural mesh of elastic and collagen fibers leaving open spaces between them, playing an essential role in supporting organs, binding skin to underlying muscles, and allowing nutrient diffusion.
