Each organ listed below contains connective tissue embedded among parenchymal cells except: A) Skin B) Brain C) Pancreas D) Liver E) Spleen
Answer (1)
Connective tissue is a type of tissue in the body that provides structural and metabolic support for other tissues and organs. It is typically found between organs, binding them together and supporting their function. Parenchymal cells, on the other hand, are the functional cells of an organ.
In this context, the question asks which organ does not have connective tissue embedded among its parenchymal cells:
Skin - The skin is composed of connective tissue in the dermis layer, whereas the epidermis above it consists of parenchymal cells like keratinocytes.
Brain - The brain primarily consists of neurons and glial cells, which are parenchymal cells. Generally, the brain has very little connective tissue compared to other organs. The supportive structure is mostly provided by other specialized cells, not connective tissue.
Pancreas - This organ contains connective tissue, which divides its parenchymal cells into lobules.
Liver - Similar to the pancreas, the liver has connective tissue forming a framework that separates the parenchymal cells into lobes and lobules.
Spleen - The spleen contains a capsule made of connective tissue and trabeculae that extend inward, providing structure and support for the organ's parenchymal cells.
Considering these details, the answer is B) Brain , as it contains the least amount of connective tissue and primarily relies on its specialized cells for structure.
