C-6 spinal ganglion, brachiocephalic artery, cerebral vein, cervical fold, cervical lamina (platysma muscle), common carotid artery, ectomeninx, esophageal muscularis, frontonasal elevation, greater thymic bud (pouch 3), inferior alveolar nerve, infraorbital nerve, lateral nasal elevation, levator scapulae muscle, longus muscles, mandibular prominence of pharyngeal arch 1, maxillary prominence of pharyngeal arch 1, medial nasal elevation, notochord, olfactory nerve, recurrent laryngeal nerve, right subclavian artery, rostral parathyroid bud (pouch 4), splenius muscle, thyroid isthmus, trabecular cartilage in nasal septum, trachea, transverse process, trapezius muscle, vagus nerve (CN X), vomeronasal nerve and nervus terminalis, vomeronasal organ

A section through the greater thymic bud (third pouch) and the isthmus of the thyroid gland.

Observe:
1. The trabecular cartilage forming in the nasal septum.
2. The infraorbital nerve in the maxillary process and the inferior alveolar nerve in the mandibular process.
3. The cervical muscle lamina in the mandibular process from which the platysma develops.
4. The origin of the right subclavian from the brachiocephalic artery.
5. The relation of the glands, vessels and nerves to the trachea and esophagus.
