Pharynx & cranial sinuses, cavities & base
Product code: HP0303
-
Whole Whole region / system / unpaired organ.
The head and neck contain the superior (upper) parts of the respiratory system and alimentary canal. The component parts of these systems act in harmony to permit eating, drinking, and breathing. This Silicone Plastinate provides unique views the oral cavity, nasal cavity and paranasal sinuses, and their relationship with the orbit via a coronal cut through the face. The pharynx is opened posteriorly to reveal the pharyngeal (posterior) surface of the tongue, soft palate and laryngeal inlet, and the cranial fossae are exposed revealing the points of cranial nerve exit through the cranial dura.

Head
- Transverse view of the meningeal arteries in an extradural position.
- Brain (cerebrum, brainstem and cerebellum) and most of the calvaria and occipital bone removed to reveal the anterior, middle and posterior cranial fossae covered in cranial dura.
- Sites of the cranial nervesy1 passing through the cranial dura (trochlear nerve (CN IV) is variably visible).
- Infundibular (pituitary) stalk covered by the diaphragma sellae.
- Site of internal carotid artery entry into the subarachnoid space from the cavernous sinus.

- Apical region of the orbits and their contents, shown with (one side) and without (opposite side) intervening connective and adipose tissues.
- Relationship of the optic nerve (CN II) with the covering meningeal layers (sheaths) and subarachnoid space.
- Coronal view of the nasal cavity, conchae, and meatae.
- Position and morphology of the ethmoidal cells (sinus) and maxillary sinuses, and their relationship with the nasal cavity and orbit.
- Temporalis (some) and masseter, and their anatomical relations.
- Parotid gland removed to reveal the facial nerve (CN VII) emerging from the stylomastoid foramen and the parotid plexus and its branches.
- Course of the parotid duct and the position of its opening (entry) into the oral vestibule.
- Alveolar ridges and dental alveolar syndesmoses.
- Relationship of the maxillary teeth with the maxillary sinus.
- Coronal view of the structure of the tongue and floor (inferior region) of the mouth, including, mylohyoid, geniohyoid, genioglossus and lingual glands.
Neck
- Cervical vertebral column removed providing posterior view of the pharynx, and the peripharyngeal space and its contents.
- Emergence of the glossopharyngeal (CN IX), vagus (CN X), spinal accessory nerve (CN XI), and hypoglossal (CN XII) nerves from their respective foramen and their course in the neck.
- Sympathetic trunk and the superior cervical ganglion.
- Common carotid artery and its bifurcation.
- Internal jugular vein passing to the jugular foramen (one side).
- Pharynx opened via a posteriorly located median sagittal incision to reveal its internal structure and connections with oral cavity, nasal cavity, larynx, and oesophagus.
- Relationship between the pharyngeal part of tongue, soft palate, vallecula, epiglottis, piriform fossae, and oesophagus.
- Mucosa of piriform fossa removed (one side) to reveal the position and course of the recurrent and internal laryngeal nerves and the internal laryngeal artery.
- Hyoid bone and structure of the larynx, including the thyroid and cricoid cartilages, associated membranes, and cricothyroid muscle.
- Attachments of the infrahyoid muscles.
- Submandibular gland and the thyroid gland shown on one side and removed on the opposite side to reveal the recurrent laryngeal nerve.
Possible variants or pathology (not guaranteed)
- Presence/visibility of all cranial nerves (e.g., trochlear nerve).
