Deep structures of the head & neck
Product code: HP0204
-
Single Side Left or right side of a region / system / organ.
The deep anatomy of the neck, face and orbit can be difficult to visualise due to numerous layers of overlying structures. This Silicone Plastinate provides clear views of the deep structures of the neck, parapharyngeal space, infratemporal fossa, face, and orbit. In addition, the median sagittal section enables exploration of the nasal and oral cavities, pharynx, and larynx. Removal of the calvaria and brain reveals the cranial fossae, and the points of cranial nerve exit from and arterial entry into the cranial cavity.

Key features include
General
- Half head and neck (left or right), including the superior thoracic vertebrae and ribs, sternum, and medial clavicle.
- Deep spaces (regions) and structures of the head and neck.
- Medial view of a median sagittal section of the head and neck.
- Superior part of calvaria and associated soft tissue removed to provide clear views of the base of skull.
- Most veins removed to provide clear views of underlying structures.
Head
- Zygomatic arch and part of the mandible (condyle, coronoid process and superior part of ramus) removed to reveal the infratemporal fossa and its main neurovascular contents.
- Anterior and superior views of the orbit and its contents (eyelids removed and orbital septum removed, and roof of orbit removed), including the lacrimal gland, the position and innervation of extraocular muscles (some), and arteries.
- Branches of the external carotid artery and their distribution.
- Brain removed to reveal the dura-lined cranial cavity and base of skull, and the sites of cranial nerve and blood vessel exit from/entry into the cranial cavity.
- Position and course of meningeal arteries (visible through cranial dura).
- Tentorium cerebelli and associated dural venous sinuses (not all).
- Position of the frontal and sphenoid sinuses.
- Relationship between the pituitary fossa and sphenoid sinus.
- Nasal cavity, nasal meatae, nasal concha and nasal choana: Part of the nasal septum may remain.
- Auricle and muscles of mastication removed.
- Lips and orbicularis oris muscle.
- Oral cavity, and the position and structure of the palate (soft and hard), tongue and floor (inferior region) of mouth.
- Parotid gland removed.
- Buccinator and the penetration of the parotid duct.
- Emergence of supraorbital, infraorbital, and mental nerves, onto the face from their respective foramen.
- Facial nerve emerging from the stylomastoid foramen, including its initial branching (parotid gland removed).
- Inferior alveolar artery and nerve and their course through part of the mandibular canal.
- Arterial supply to the face and part of the scalp.
Neck
- Partial or complete removal of sternocleidomastoid, trapezius, various hypaxial and epaxial muscles of the back, and veins to provide clear views of deeply located spaces, arteries, nerves, and muscles of the neck.
- Course and bifurcation of the common carotid artery.
- Cervical branches of the external carotid artery.
- Position and course of the vagus (CN X), hypoglossal (CN XII), and phrenic nerves, and ansa cervicalis.
- Suprahyoid and infrahyoid muscles.
- Arrangement and relations of the scalenus muscles.
- Brachial plexus, subclavian artery and cervical plexus emerging from between the scalenus muscles.
- Structure and position of the thyroid gland, and superior thyroid artery.
- Structure of the larynx, including the thyroid and cricoid cartilages, associated membranes, and the vocal and vestibular folds.
- Hyoid bone and related (attached) structures.
- Position, structure, regions, and communication of the pharynx, including the torus tubarius.
- Location and communication of the retropharyngeal (danger) space.
- Structure of the vertebral column (superior part), including the intervertebral discs and median atlanto-axial joint (medial view).
- Spinal cord in the vertebral canal, with meningeal coverings and epidural space.
- Suboccipital region and its contents, including regional muscles, triangles, and nerves.
- Apical region of thorax, with parietal pleura removed to reveal the superior thoracic aperture and associated structures, including the root of the T1 spinal nerve and the sympathetic trunk and ganglia.
- Structure of the superior part of the thoracic wall, including the intercostal spaces, sternoclavicular joint, and medial clavicle.
