Head, ventral aspect: level of Zymbal's gland.
Head, dorsal aspect after removal of skull cap and brain: Zymbal's gland (Ma: meatus acusticus externus, P: pituitary gland, Eb: ethmoidal bullae).
| Species: | Rats and Mice |
| Organ: | Zymbal gland |
| Localization: | Adjacent to the auditory canal |
| Number of sections: | 1 |
| Direction: | Transverse |
| Remarks: | A preparation of the Zymbal's gland is not advisable, instead a transverse section across the base of the decalcified skull at both ethmoidal bullae is performed. |

 Zymbal's gland (Z), ethmoidal bullae (Eb). |
The Zymbal's glands are made up of several lobules of modified sebaceous glands which are located at the base of the external ear (anterio-ventral). A section through the base of the skull at the level of the external ears generally results in a section plane through one or more lobules of Zymbal's glands tissue.
