The term "plexus gastricus inferior" refers to the lowest branch of the gastric plexus found in the abdomen. The spelling of this word can be tricky due to its complex structure. Using the International Phonetic Alphabet (IPA), we can break down the pronunciation: /ˈplɛksəs ˈɡæstrəkəs ɪnˈfɪəriər/. The first two syllables are pronounced as "pleks-us", with a short "e" sound. In the third syllable, "gastro", the "a" is pronounced as "æ". The fourth and fifth syllables are pronounced as "in-feer-ee-er".
The term "plexus gastricus inferior" refers to a complex network of nerves located in the lower part of the stomach. It is also known as the inferior gastric plexus. The stomach is innervated by a series of interconnected nerve fibers that form this plexus, which plays a crucial role in regulating various digestive functions.
The plexus gastricus inferior is primarily responsible for local regulation of gastric motility and secretion. It receives fibers from both the sympathetic and parasympathetic divisions of the autonomic nervous system. The sympathetic fibers, originating from the celiac ganglia, inhibit gastric activity and promote relaxation of the stomach muscles. Conversely, the parasympathetic fibers, originating from the vagus nerve, stimulate gastric activity and enhance contraction of the stomach.
This network of nerves connects with other digestive plexuses, such as the superior gastric plexus and the celiac plexus, to collectively coordinate the overall functioning of the gastrointestinal system. Dysfunction or damage to the plexus gastricus inferior can lead to various gastrointestinal disorders, such as delayed gastric emptying, gastroparesis, or abnormal gastric motility.
Overall, the plexus gastricus inferior is essential for regulating gastric movement, secretion, and overall digestive processes. Its intricate connections with other nerve networks ensure the harmonious functioning of the stomach, allowing for proper digestion and absorption of nutrients.
