Bundle of His is a network of

• A. Muscle fibres distributed throughout the heart walls
• B. Muscle fibres found only in the ventricle wall
• C. Nerve fibres distributed in ventricles
• D. Nerve fibres found throughout the heart

The Bundle of His is a crucial component of the heart's electrical conduction system. It is primarily responsible for transmitting signals that coordinate heartbeats.

What is the Bundle of His?

The Bundle of His consists of specialized muscle fibers that play a key role in the heart's function.

Location and Function

• A. Muscle fibres distributed throughout the heart walls: This option is incorrect as the Bundle of His is not found throughout the entire heart.
• B. Muscle fibres found only in the ventricle wall: This is also incorrect; while it is associated with the ventricles, it is not limited to just their walls.
• C. Nerve fibres distributed in ventricles: This option is misleading; the Bundle of His is not made up of nerve fibers.
• D. Nerve fibres found throughout the heart: This is incorrect as well; the Bundle of His consists of muscle fibers, not nerve fibers.

Correct Answer

The Bundle of His is best described as a network of muscle fibers that is part of the heart's conduction system, specifically located in the interventricular septum. Therefore, none of the provided options accurately describe it, but it is closest to being a network of muscle fibers involved in heart function.
