Definition

Noun: - A network of interwoven sympathetic and parasympathetic nerve fibers. This term refers to an intricate web of nerves that are part of the autonomic nervous system, which controls involuntary bodily functions.

Usage

• The term "plexus autonomici" is a specialized anatomical term. It is used in medical, biological, and scientific contexts to describe the complex neural networks that regulate automatic processes like heart rate, digestion, and glandular secretion.
• It is often discussed in relation to specific autonomic plexuses, such as the cardiac plexus or the celiac plexus.

Examples

• The surgeon carefully avoided the plexus autonomici surrounding the aorta during the procedure.
• Damage to the plexus autonomici can lead to dysautonomia, a disorder of autonomic nervous system function.
• The study focused on how neurotransmitters affect signal transmission within the plexus autonomici.

Advanced Usage

• The term is typically used in its plural form ("plexus autonomici") as it denotes a collective network system. The singular form "plexus autonomicus" is less common but may be encountered.
• In detailed anatomical descriptions, it may be specified as part of a compound structure, e.g., "the pelvic part of the plexus autonomici."
