Tactile input from the larynx, carried along the Blank______ nerve, can initiate coughing. Multiple choice question.hypoglossalfacialaccessoryvagus

Step 1: Break Down the Problem

To answer the question, we need to identify which of the listed nerves is responsible for carrying tactile input from the larynx that can stimulate coughing.

Step 2: Relevant Concepts

• The vagus nerve (Cranial Nerve X) plays a crucial role in the autonomic nervous system and is responsible for carrying sensory information from the larynx.
• The hypoglossal nerve (Cranial Nerve XII) primarily controls tongue movements.
• The facial nerve (Cranial Nerve VII) is involved in facial expressions and does not supply sensory fibers to the larynx.
• The accessory nerve (Cranial Nerve XI) mainly innervates the sternocleidomastoid and trapezius muscles.

Step 3: Analysis and Detail

The sensory input from the larynx is predominantly carried by the vagus nerve. When the larynx is stimulated (e.g., by irritants), the vagus nerve signals the cough reflex.

Step 4: Verify and Summarize

Given that the vagus nerve is indeed responsible for transmitting tactile sensations from the larynx, it facilitates the cough reflex when activated by irritants.

Final Answer

The correct answer is vagus.
