Question

I need a visual diagram of the neuons and how tbey are connected on number 32. (muscle of ONLY the larynx .... explaning an efferent nervous pathway. on how it projects voice and how its neurons connect to the primary motor cortex , corticobular tract , medulla or spinal cord , accessory juglar foramen to the larynx .

31. Medulla oblongata --> motor Vagus (jugular foramen) (PARASYMPATHETIC) -> Stomach/intestines (Enteric nervous system), pancreas 32. Primary motor cortex --> Corticobulbar tract --> Medulla oblongata/Spinal cord --> Accessory (jugular foramen) --> muscles of soft palate, pharynx, larynx, sternocleidomastoid, trapezius

Answer 1

Visual diagram :-

Accessory nerve To soft palate and pharyngeal muscles Cranial roots Spinal roots (C1-C6) External branch of - accessory nerve Trapezius muscle Stemocleidomastoid muscle

Jugular foramen Pons Vagus nerve (X) Cranial root diverges and joins vagus nerve Medulla oblongata Cranial root Spinal root Foramen magnum Cervical region of spinal cord (C-C) Accessory nerve (XI) Trapezius muscle Sterno- cleidomastoid muscle
