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.

- Intraglandular parotid nodesNodi parotidei intraglandularesLymph nodes embedded within the substance of the parotid salivary gland, in front of and below the ear.
- Intraparietal sulcusSulcus intraparietalisA long groove across the outer face of the parietal lobe that divides the superior from the inferior parietal lobule.
- IrisThe coloured, ring-shaped diaphragm of the eye, lying between cornea and lens, whose central opening, the pupil, controls how much light enters.
- Lacrimal arteryArteria lacrimalisAn offshoot of the ophthalmic artery that runs along the lateral wall of the orbit to feed the lacrimal gland and nearby tissues.
- Lacrimal boneOs lacrimaleThe smallest and most fragile bone of the face, set in the front of the inner orbital wall where it cradles the tear sac.
- Lacrimal canaliculusCanaliculus lacrimalisA fine tear-draining channel in the medial part of each eyelid, running from the lacrimal punctum to the lacrimal sac.
- Lacrimal glandGlandula lacrimalisThe almond-shaped tear gland lying in the upper outer corner of each orbit, which makes the watery layer of the tear film.
- Lacrimal sacSaccus lacrimalisThe closed upper end of the nasolacrimal passage, lying in the lacrimal fossa at the medial wall of the orbit and receiving the canaliculi.
- Lateral frontobasal arteryArteria frontobasalis lateralisAn early cortical branch of the middle cerebral artery that runs forwards to the outer part of the orbital surface of the frontal lobe.
- Lateral geniculate bodyCorpus geniculatum lateraleA small, knee-shaped swelling at the back of the thalamus where the optic tract ends and vision is relayed to the cortex.
- Lateral occipital arteryArteria occipitalis lateralisOne of the two end branches of the posterior cerebral artery, running under the temporal and occipital lobes on the base of the brain.
- Lateral occipitotemporal gyrusGyrus occipitotemporalis lateralisThe spindle-shaped fusiform gyrus on the underside of the temporal and occipital lobe, a key region for recognising faces, bodies and words.
- Lateral pontine branches of basilar arteryRami laterales pontis arteriae basilarisBranches of the basilar artery that wind around the side of the pons to supply its lateral part and the middle cerebellar peduncle.
- Lateral process of nasal septal cartilageProcessus lateralis cartilaginis septi nasiThe flat triangular cartilage forming the upper side wall of the external nose, just below the nasal bone on each side.
- Lateral rectus muscleMusculus rectus lateralis bulbi oculiThe lateral rectus is the straight muscle on the outer side of the eyeball that turns the eye away from the nose.
- Lateral temporomandibular ligamentLigamentum temporomandibulare lateraleThe thickened outer wall of the jaw joint capsule, running from the articular tubercle down and back to the mandibular neck.
- Lateral ventricleVentriculus lateralisThe large, C-shaped cavity inside each cerebral hemisphere, filled with cerebrospinal fluid and opening into the third ventricle.
- LensThe transparent, biconvex focusing body of the eye, hung behind the iris from the ciliary body by the zonular fibres.
- Lentiform nucleusNucleus lentiformisA lens-shaped mass of grey matter deep in each cerebral hemisphere, made of the putamen and globus pallidus, beside the internal capsule.
- Levator anguli orisThe levator anguli oris is a deep facial muscle running from the maxilla's canine fossa to the mouth's corner, which it raises.
- Levator labii superiorisThe levator labii superioris is a flat facial muscle running from the lower orbital rim into the upper lip, which it lifts.
- Levator nasolabialisLevator labii superioris alaeque nasi: a narrow muscle beside the nose that lifts both the upper lip and the wing of the nostril.
- Levator palpebrae superiorisThe levator palpebrae superioris is the thin muscle in the roof of the orbit that raises the upper eyelid and keeps the eye open.
- Lingual gyrusGyrus lingualisA tongue-shaped gyrus on the medial and lower surface of the occipital lobe, lying between the calcarine and collateral sulci.
