Orbit & deep structures of the head & neck
Product code: HP0302
-
Whole Whole region / system / unpaired organ.
The deep anatomy of the head, neck and orbit is difficult to visualise due to numerous overlying structures and the complexity of dissection. This Silicone Plastinate provides clear views of the structures within the parapharyngeal space, neck triangles, infratemporal fossa, cavernous sinus, face, oral cavity, and orbit, with different levels of dissection shown across the left and right sides. The arrangement and contents of the orbit can be explored from multiple and unique perspectives, both with and without the eyeball, allowing the position and functions of the extraocular muscles to be visualised. In addition, the points of exit of the cranial nerves through the cranial dura, the trigeminal ganglion and the cervical spinal cord are also revealed.

Key features include
General
- Whole head and neck.
- Calvaria opened via a transverse cut and the brain removed.
Head
- Transverse view of the meningeal arteries in an extradural position.
- Position of the transverse and sigmoid dural venous sinuses.
- Cranial dura covering the cranial fossae (one side) and partially removed (opposite side) to reveal the contents of the cavernous sinus and trigeminal cave.
- Cranial nerves passing through the cranial dura (exit points).
- Infundibular (pituitary) stalk covered by the diaphragma sellae.
- Sites of vertebral and internal carotid artery entry into the subarachnoid space.
- Trigeminal ganglion, including its three branches exiting the cranium, and their subsequent course and branching.
- Orbit and its contents, revealed from lateral and superior perspectives (one side) and from an anterior perspective with eyeball removed (opposite side).
- Relationship of orbit and eyeball with the infraorbital nerve.
- Relationship of the optic nerve (CN II) with the covering meningeal layers (sheaths) and subarachnoid space.
- Part of the nose and maxilla removed to reveal the nasolacrimal duct and inferior nasal concha.
- Facial nerve (CN VII) emerging from the stylomastoid foramen.
- External acoustic meatus (cartilaginous and bony parts) opened anteriorly (one side).
- Centrally located facial muscles retained (one side) and removed (opposite side).
- Emergence of supraorbital and infraorbital nerves onto the face from their respective foramen.
- Infratemporal fossa with the pterygoid muscles removed to reveal its neurovascular contents variably across the left and right sides.
- Muscles and ligaments originating from the styloid process.
- Mandible, buccinator and lips removed (one side) to reveal the maxillary alveolar processes, and muscles and nerves in the floor (inferior region) of the mouth.
- Sublingual gland and its relationship with the submandibular duct.
Neck
- Internal jugular veins removed to reveal the common carotid arteries, their bifurcation and relationship with nerves within the neck.
- Morphology, course, and relations of the external carotid artery and some of its branches.
- Position and course of the vagus (CN X), spinal accessory (CNXI), hypoglossal (CN XII), and phrenic nerves, and ansa cervicalis.
- Hyoid bone and the external structure of the larynx, including the thyroid and cricoid cartilages, associated membranes, and cricothyroid muscle.
- Thyroid gland, and the origin and course of the superior thyroid artery.
- Arrangement and relations of the scalenus muscles, including their inferior attachment.
- Subclavian artery and some of its branches.
- Structures emerging from between the scalenus muscles, including the brachial plexus, cervical plexus, and subclavian artery.
- Posterior arch of Atlas (vertebra C1) and its relationship with the vertebral artery.
- Laminectomy of the cervical and superior thoracic vertebrae, with the meninges opened and arranged in layers, reveals the epidural space and a posterior view of the spinal cord in the vertebral canal and posterior roots of the spinal nerves.
- Apical region of the thoracic cavity, with cervical parietal pleura removed to reveal the superior thoracic aperture and associated structures, including the T1 spinal nerve, sympathetic trunk, and sympathetic ganglia.
- Structure of the superior part of the thoracic wall, including the sternoclavicular joint, medial clavicle, and attachments of subclavius.
