Central nervous system & spinal nerves in situ
Product code: HP1216
-
Whole Whole region / system / unpaired organ.
The central and peripheral nervous systems function as a cohesive whole to monitor, modulate, and control all body functions. The connections and continuity between these nervous systems, their topographical layout and relationship with surrounding structures are normally difficult to visualise. This Silicone Plastinate uniquely reveals the morphology, orientation, and connections between the central and peripheral nervous systems, in relation to the axial skeleton. The brain, cranial nerves (most), spinal cord, spinal nerves, and major plexuses are revealed, alongside the structure of the thoracic and abdominal walls and the deep muscles of the back.

Typical Features
General
- Cerebrum, brainstem, spinal cord and spinal nerves (cerebellum not visible).
- Brachial and lumbosacral plexuses.
- Base of cranium (part), vertebral column (part), pelvis and parts of the thoracic and abdominal walls.
Cranium & Brain
- Most of cranium removed (parts of temporal and occipital bones remain) to reveal the cerebrum and brainstem with arachnoid removed.
- External features of the cerebrum including its hemispheres, lobes, lobules, fissures, sulci, and gyri.
- Olfactory bulb and tract.
- Optic chiasm and its relationship with the pituitary gland, and optic nerves.
- External features of the anterior pons and medulla oblongata, including the pyramids and olives.
- Facial nerve (CN VII) emerging from the stylomastoid foramen.
- Glossopharyngeal (CN IX), vagus (CN X) and spinal root of accessory (CN XI) nerves emerging from the jugular foramen.
- Internal carotid artery within the carotid canal and cranium.
- Course of the vertebral and basilar arteries.
Vertebral Column & Spinal Cord
- Bodies of most cervical, thoracic and lumbar vertebra removed.
- Dura and arachnoid opened via a median sagittal cut to reveal the spinal cord and cauda equina in the lumbar cistern.
- Continuity between the brainstem and spinal cord.
- Changing morphology of the spinal cord across regions.
- Anterior spinal artery.
- Spinal nerves exiting the intervertebral foramina.
- Deep dissection of the back revealing posterior rami of spinal nerves
- Various epaxial muscles of the back including the suboccipital and transversospinal muscles.
- Suboccipital triangle with the suboccipital nerve and vertebral artery.
- Greater occipital nerve and the dorsal ramus of C3.
- Structure of the posterolateral thoracic wall.
- Cross sectional view of the layered structure of the abdominal wall, and the inferior lumbar triangle.
- Morphology, bony landmarks and various ligaments of the pelvis.
- Greater and lesser sciatic foramina and the obturator membrane.
Peripheral nerves
- Rootlets, roots, and posterior (dorsal) ganglia of the spinal nerves.
- Differential sizes of the spinal nerves relative to their function.
- Brachial, lumbar, and sacral plexuses and various branches.
Possible variants or pathology
- Morphology of the vertebral column (e.g. thoracic kyphosis)
- Position and extent of sulci, gyri and fissures.
- Amount of the olfactory bulb retained.
- Length of the spinal nerves.
- Pattern of spinal nerves contributing to a plexus.
- Branching pattern of vessels, nerves and plexuses.
- Position and course of vessels and nerves.
- Tortuosity of arteries.
- Arterial aneurysm and atherosclerosis.
- Orthopaedic implants.
- Osteoarthritis and disease-related joint deformity.
- Rheumatological bone and soft tissue changes.
- Morphology and position of muscles.
- Muscle attachment points, morphology, and fibre arrangement.
- Age-related changes to muscles.
Available customisations
- Retain sympathetic trunks with associated ganglia and various splanchnic nerves.
- Retain arachnoid on one cerebral hemisphere.
- Retain arachnoid on both cerebral hemispheres.
- Retain retina.
- Laminectomy to also show spinal cord and nerves from a posterior perspective.
- Retain strip of dura with superior sagittal sinus.
- Please contact us to discuss bespoke customisations.
Plastinate designs are standardized, yet no Plastinates are alike. Feature uniqueness occurs due to the use of real human tissue and hand craftsmanship. Learn more here.
