2.5:1 Enlarged 12 pairs cerebral nervous Anatomical model Head neck vessels

Description: This new design, with a high magnification (2.5 times magnification), shows in detail the direction of the twelve pairs of human cranial nerves in the head with a longitudinal cut design and the eye can be removed to see the detailed optic nervous system and the neck with a layer cut design showing the muscles, arteries and veins in the neck. Is the neurology and cosmetic surgery and so on medical teaching and learning demonstration of a rare product! Size: 40*26*41.5CMhigh quality PVC material The cranial nerve is also called "cranial nerve". From the brain comes a pair of nerves. There are 12 pairs, the order of which is usually expressed in Roman order. · Olfactive nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, auditory nerve, glossopharyngeal nerve, vagus nerve, accessory nerve and hypoglossal nerve, among which trigeminal nerve is composed of eye meridian, maxillary nerve and mandibular nerve respectively. The model has part of the skull base. The superior and lateral walls of the orbit have been dissected, exposing the eyeball, the extraocular muscles and the orbital nerves, the mandibular rami and part of the temporal bone, the superficial muscles of the neck, and the distribution of the cranial nerves in the neck. Twelve pairs of cranial nerves entering and leaving the fissure of the skull base can be seen in the inner surface of the skull base. On the median surface, olfactory nerve fibers can be seen in the mucosa of the superior turbinate through the ethmoid into the olfactory bulb, and the lateral wall of the nasal cavity is cut open to expose the pterygopalatine ganglion and its branches. The orbit shows the distribution of the location of the eyeball, the extraocular muscle, the oculomotor nerve, the trochlear nerve, the abducens nerve, the ophthalmic branch of the trigeminal nerve and the ciliary ganglion. The mandibular rami and part of the temporal bone have been removed to reveal the maxillary nerve of the trigeminal nerve, the course, branch, distribution of the mandibular nerve and the submandibular ganglion. The facial nerve is separated from the superficial nerve and the chordae tympani in the facial nerve canal; the glossopharyngeal nerve and the vagus nerve run and distribute in the neck; the accessory nerve innervates the sternocleidomastoid muscle and the trapezius muscle; and the hypoglossal nerve enters the tongue.
