Non-glandular

Referring to or characteristic of tissues, cells, or structures that are not glands and therefore do not secrete substances like hormones, enzymes, or mucus. These tissues lack the specialized cells required for secretion and primarily serve structural, protective, or supportive functions within the body. non-glandular structures can vary widely in their composition and location, playing diverse roles in maintaining overall organismal health. They are distinct from glandular tissues which are dedicated to the synthesis and release of specific products.
