Körtelartad

Körtelartad is a Swedish term that translates to "glandular" in English. It is used in biological and medical contexts to describe tissues or structures that have the characteristics of glands. Glands are organs that produce and secrete substances, such as hormones, enzymes, mucus, or sweat.

When a tissue is described as körtelartad, it means it possesses the microscopic features associated with glandular tissue. This typically includes specialized cells arranged in specific patterns, such as acini (sac-like structures) or tubules, which are responsible for the production and release of their secretory products. These cells often have abundant endoplasmic reticulum and Golgi apparatus, which are involved in protein synthesis and modification, and the transport of secretory vesicles.

In histology, the study of microscopic anatomy, identifying körtelartad structures is crucial for diagnosing diseases and understanding normal physiological processes. For example, many types of tumors can arise from glandular tissue, and their microscopic appearance as körtelartad is a key diagnostic feature. Conversely, the absence or alteration of körtelartad features in a normally glandular tissue can indicate disease. The term can be applied to a wide range of tissues, including those in the digestive system, endocrine system, and exocrine glands.
