28 sie 2024 · The pharyngeal nerve is a nerve of the head and neck. It is a branch of the maxillary division of the trigeminal nerve. It supplies sensory and parasympathetic innervation to the mucosa of the superior nasopharynx.
25 paź 2022 · The network of nerves supplying the heart is called the cardiac plexus. It receives contributions from the right and left vagus nerves , as well as contributions from the sympathetic trunk . These are responsible for influencing heart rate, cardiac output, and contraction forces of the heart.
30 paź 2023 · The maxillary nerve (CN V/II) supplies the anterior and superior nasopharynx, while the tonsillar nerves carry fibers from both the glossopharyngeal nerve (CN IX) and the vagus nerve (CN X). The motor branches come from the pharyngeal plexus and carry fibers from the vagus nerve (CN X).
7 paź 2023 · The vagus nerve innervates the majority of the muscles associated with the pharynx and larynx. These muscles are responsible for the initiation of swallowing and phonation. Pharynx.

Supplying muscles of the pharynx and larynx. b. Visceral sensory. This component of the vagus nerve is responsible for transmitting information from a wide variety of anatomical sites including the heart and lungs, pharynx and larynx, and upper part of the gastrointestinal tract. c. Visceral motor
1 maj 2023 · Specifically, the motor innervation of the STP muscle is mostly from the glossopharyngeal nerve, while the vagus nerve supplies the innervation to the other pharyngeal muscles. The pharyngeal muscles have a high nerve-muscle fiber ratio of 1:2 to 1:6 which allows for precisely coordinated pharyngeal functions. [2]
