Purkinje Fiber

Description:

Purkinje fibers, also known as Purkinje cells or Purkinje neurons, are specialized cardiac muscle fibers that play a vital role in the conduction of electrical impulses through the heart. These fibers are responsible for transmitting signals from the atrioventricular node to the muscles of the ventricles, allowing for efficient and coordinated heart contractions. Purkinje fibers are larger and have more extensive branching than regular cardiac muscle cells, enabling them to rapidly distribute electrical signals throughout the ventricles.

Senses and Usages:

1. Medical:

   • Noun: Purkinje fiber refers to a specialized cardiac muscle fiber involved in the conduction system of the heart.
   • Noun: Purkinje cells are found predominantly in the ventricles of the heart and are responsible for efficient electrical signal transmission within the heart.
   • Noun: Purkinje neurons are specialized cells located in the cerebellum that play a crucial role in coordinating movements and maintaining balance.

Sample Sentences:

• The doctor observed abnormal signals in the patient's Purkinje fibers, indicating potential heart conduction issues.
• Studies have shown that damage to the Purkinje cells can result in irregular heart rhythms.
• Researchers are investigating the role of Purkinje neurons in motor coordination and balance disorders.
