BASAL GRANULE Meaning and
Definition
-
A basal granule refers to a small, dense, and round organelle found within the cytoplasm of certain cells, specifically in the basal region or base of the cell. These granules are usually present in cells involved in secretion, such as mucous or serous glands, as well as in some specialized cells like nerve cells or neurons.
Basal granules are composed of vesicles, which are small, membrane-bound sacs containing various substances. These vesicles may contain secretory products, such as proteins, enzymes, hormones, or neurotransmitters, depending on the specific type of cell they are found in. The granules are formed by the process of exocytosis, where the vesicles fuse with the cell membrane and release their contents to the outside of the cell.
In secretory cells, the basal granules play a crucial role in transporting and storing the secretory substances until they are ready to be released. They act as reservoirs or depots, enabling the cell to produce and accumulate the secretion over time, so it can be released in a controlled and regulated manner.
The presence of basal granules is often indicative of a cell's secretory activity, as they are a prominent feature seen under a microscope. These granules can be visualized using specific staining techniques or electron microscopy, enhancing their visibility and aiding in their identification.

Etymology of BASAL GRANULE
The word "basal" comes from the Latin word "basalis", which means "of or pertaining to the base". It is derived from the Latin word "basis", meaning "foundation" or "base".
The word "granule" comes from the Latin word "granulum", which means "small grain". It is a diminutive form of the Latin word "granum", meaning "grain" or "seed".
In the context of biology and anatomy, "basal granule" often refers to small granules present at the base or bottom of certain structures, such as cells or organelles. The term "basal granule" is formed by combining the two words, "basal" and "granule", to describe these specific granules located at the base.
