State whether the following statements are true or false. Purkinje's fibres are nerve fibres supplying the ventricular muscle.

Explanation

To determine whether the statement "Purkinje's fibres are nerve fibres supplying the ventricular muscle" is true or false, we can follow these steps:

### Step 1: Understand the Role of Purkinje Fibres
Purkinje fibres are specialized muscle fibres found in the heart. They are part of the cardiac conduction system and are responsible for conducting electrical impulses that stimulate the contraction of the ventricles.

### Step 2: Identify the Composition of Purkinje Fibres
Purkinje fibres are not nerve fibres; they are modified cardiac muscle cells. Their primary function is to ensure that the electrical signals are transmitted quickly and efficiently throughout the ventricles, leading to coordinated contraction.
