Lymphatic drainage of larynx above the vocal cord drains into
The larynx is divided into supraglottic and glottic regions. The vocal cords are part of the glottis. I remember that lymphatic drainage patterns can differ based on the region. The supraglottic area, which is above the vocal cords, usually drains to the upper deep cervical nodes. The glottic area, including the vocal cords themselves, might drain into the pretracheal or paratracheal nodes. But the question specifically asks about above the vocal cords, so that's the supraglottic region.
Wait, there's also a distinction between the lymphatic drainage of the supraglottic and glottic regions. The supraglottic part drains to the jugulodigastric nodes, which are part of the upper deep cervical chain. The glottic part, like the vocal cords, drains to the pretracheal nodes. So if the question is about above the vocal cords, the answer would be the upper deep cervical nodes. Let me check some sources or my notes to confirm.
Yes, the larynx above the vocal cords (supraglottic) drains to the upper deep cervical lymph nodes, specifically the jugulodigastric nodes. The lower part (glottic) goes to pretracheal and paratracheal nodes. So the correct answer should be the upper deep cervical nodes. The options might include other nodes like pretracheal, paratracheal, or submandibular. I need to make sure the distractors are other nodes. Now, the user didn't provide the actual options, but based on common MCQs, the options are likely A: Upper deep cervical, B: Pretracheal, C: Paratracheal, D: Submandibular. So the correct answer is A. Upper deep cervical.
Let me verify again. The supraglottic larynx (above vocal cords) drains to upper deep cervical nodes. The glottic (vocal cords) to pretracheal and paratracheal. So the answer is A. Now, the incorrect options: pretracheal and paratracheal are for glottic, submandibular is for other areas like the oral cavity. So the explanation should clarify that. The clinical pearl is that cancer above the vocal cords tends to spread to upper cervical nodes, whereas below might spread to pretracheal. That's important for staging and treatment planning.
**Core Concept**
The larynx is divided into supraglottic (above vocal cords) and glottic (vocal cords) regions. **Supraglottic lymph** drains to **upper deep cervical (jugulodigastric) nodes**, while glottic lymph drains to **pretracheal/paratracheal nodes**. This distinction is critical for staging laryngeal cancer and planning neck dissections.
**Why the Correct Answer is Right**
The supraglottic larynx (epiglottis, aryepiglottic folds, false vocal cords) has **
