FIBRILLA Meaning and
Definition
-
A fibrilla is a term used in anatomy and biology to describe a very slender, thread-like structure or element. It refers specifically to a small, fine fiber or filament that forms a part of a larger structure or tissue.
In the context of muscle anatomy, fibrilla commonly refers to a myofibril. Myofibrils are tiny, cylindrical structures found within muscle fibers that are responsible for muscle contractions. Each myofibril is composed of even smaller fibrils, known as sarcomeres, and these sarcomeres are further made up of protein filaments called actin and myosin. The precise arrangement and interaction of these filaments within the fibrilla allows for muscular contraction and relaxation.
Additionally, fibrilla can also pertain to other biological structures, such as nerve fibers. In the nervous system, fibrilla refers to the thread-like extensions emanating from neurons, which transmit signals to and from other nerve cells. These extensions, often referred to as axons or dendrites, contain bundles of even smaller fibrils, known as microtubules, that play a crucial role in the transmission of electrical impulses across the nervous system.
Overall, fibrilla embodies the concept of slender, thread-like structures found within various tissues and systems of the body, fulfilling important physiological functions.
