The human body one structure at a time. Every page has a 3D model you can turn, with its parts numbered on it, where it sits, what it does and what supplies it.

- Nucleus of trochlear nerveNucleus nervi trochlearisA small motor nucleus in the lower midbrain whose axons cross and leave the back of the brainstem as the trochlear nerve to superior oblique.
- Oculomotor nerve (III)Nervus oculomotorius (III)The third cranial nerve, running from the midbrain to the orbit to move most eye muscles, lift the upper lid and narrow the pupil.
- Olfactory nerve (I)Nervus olfactorius (I)The first cranial nerve: fine bundles carrying smell from the roof of the nasal cavity through the ethmoid bone to the olfactory bulb.
- Ophthalmic nerveNervus ophthalmicusThe smallest, uppermost trigeminal division, sensory to the eye, upper eyelid, forehead, scalp and part of the nose.
- Optic nerve (II)Nervus opticus (II)The second cranial nerve, a bundle of axons from the retina running through the optic canal to the optic chiasm.
- Posterior division of mandibular nerveDivisio posterior nervi mandibularisThe larger hind trunk of the mandibular nerve, mainly sensory, ending in three large nerves for the ear, tongue and lower teeth.
- Posterior nucleus of vagus nerveNucleus posterior nervi vagiThe main parasympathetic nucleus of the vagus nerve, lying in the medulla beneath the fourth ventricle and serving the gut and lungs.
- Sensory root of trigeminal nerveRadix sensoria nervi trigeminiThe large sensory root of the fifth cranial nerve, running from the trigeminal ganglion into the side of the pons.
- Trigeminal nerve (V)Nervus trigeminus (V)The fifth cranial nerve, leaving the side of the pons to give feeling to the face and to work the chewing muscles.
- Trochlear nerve (IV)Nervus trochlearis (IV)The fourth cranial nerve, a slender motor nerve leaving the back of the midbrain to supply the eye's superior oblique muscle.
- Tympanic membraneMembrana tympanicaThe eardrum: a thin, slightly conical membrane at the inner end of the ear canal, separating the outer ear canal from the middle ear cavity.
- Vagus nerve (X)Nervus vagus (X)The tenth cranial nerve, which wanders from the medulla through the neck and chest into the abdomen to serve the viscera.
- Vestibular nerveNervus vestibularisThe balance division of the eighth cranial nerve, carrying signals from the semicircular canals, utricle and saccule to the brainstem.
- Vestibulocochlear nerve (VIII)Nervus vestibulocochlearis (VIII)The eighth cranial nerve, which carries hearing and balance signals between the inner ear and the brainstem via the internal acoustic meatus.
- Zonular fibresFibrae zonularesFine fibres that hold the lens of the eye in place, running from the ciliary body to the lens capsule around its equator.
