A section through the C-7 spinal ganglion and clavicle.

Observe:
1. The nasal capsule condensation surrounding the primitive nasal cavity.
2. The primordium of the first digit of the hand.
3. The recurrent laryngeal nerve between the trachea and esophagus.
4. The jugular lymph sac lateral to the internal jugular vein.
5. The sympathetic trunk lateral to the esophagus.
