- Abducens nerve (VI)Nervus abducens (VI)The sixth cranial nerve, a purely motor nerve from the pons that moves the eye outwards by supplying the lateral rectus muscle.
- Accessory branch of middle meningeal arteryRamus accessorius arteriae meningeae mediaeA small artery in the infratemporal fossa, from the middle meningeal or maxillary artery, that enters the skull through the foramen ovale.
- Accessory nerve (XI)Nervus accessorius (XI)The eleventh cranial nerve, a motor nerve that rises from the upper spinal cord, loops through the skull and supplies sternocleidomastoid and trapezius.
- Accessory nucleus of oculomotor nerveNucleus accessorius nervi oculomotoriiA small parasympathetic cell group in the midbrain, beside the oculomotor nucleus, that drives pupil constriction and focusing of the lens.
- Ampulla of lacrimal canaliculusAmpulla canaliculi lacrimalisA small widening at the bend of each lacrimal canaliculus, near the inner corner of the eyelid, on the tears' route to the lacrimal sac.
- Amygdaloid bodyCorpus amygdaloideumAn almond-shaped cluster of nuclei deep in the front of each temporal lobe, central to emotion, fear learning and emotional memory.
- Angular arteryArteria angularisThe final stretch of the facial artery, climbing beside the nose to the inner corner of the eye.
- Angular gyrusGyrus angularisA curved fold of cortex in the inferior parietal lobule, arching around the end of the superior temporal sulcus, important for reading and number.
- Angular veinVena angularisA short vein at the inner corner of the eye that forms the uppermost part of the facial vein beside the nose.
- Anterior cerebral arteryArteria cerebri anteriorThe smaller terminal branch of the internal carotid artery, curving over the corpus callosum to supply the medial surface of the frontal and parietal lobes.
- Anterior chamber of eyeballCamera anterior bulbi oculiThe fluid-filled space at the front of the eye, bounded by the back of the cornea in front and the iris and lens behind.
- Anterior cochlear nucleusNucleus cochlearis anteriorThe ventral division of the cochlear nuclei at the pontomedullary junction, the first relay of hearing in the brainstem.
- Anterior commissureCommissura anteriorA compact bundle of fibres crossing the midline in front of the fornix, linking the two temporal lobes and olfactory regions.
- Anterior communicating arteryArteria communicans anteriorA short midline vessel linking the two anterior cerebral arteries at the front of the cerebral arterial circle.
- Anterior deep temporal arteryArteria temporalis profunda anteriorA branch of the maxillary artery that climbs between the skull and the front part of temporalis, supplying that muscle from its deep surface.
- Anterior division of mandibular nerveDivisio anterior nervi mandibularisThe smaller front trunk of the mandibular nerve in the infratemporal fossa, mostly motor to the chewing muscles with one sensory branch to the cheek.
- Anterior division of retromandibular veinDivisio anterior venae mandibularisThe forward branch of the retromandibular vein, which leaves the parotid gland to join the facial vein below the jaw.
- Anterior ethmoidal arteryArteria ethmoidea anteriorAn ophthalmic artery branch that leaves the orbit through its medial wall to supply the ethmoid cells, the anterior cranial fossa and the nose.
- Anterior inferior cerebellar arteryArteria cerebelli inferior anteriorA basilar artery branch arising near the lower pons that supplies the front of the cerebellar undersurface and the lateral pons.
- Anterior intercavernous sinusSinus intercavernosus anteriorA small dural venous sinus crossing the midline in front of the pituitary gland, joining the two cavernous sinuses.
- Anterior jugular veinVena iugularis anteriorA superficial vein running down the front of the neck beside the midline, from near the hyoid bone to the root of the neck.
- Anterior quadrangular lobuleLobulus quadrangularis anteriorThe part of each cerebellar hemisphere in the anterior lobe that lies beside the culmen, in front of the primary fissure.
- Anterior segment of eyeballSegmentum anterius bulbi oculiThe front portion of the eyeball, comprising cornea, iris, ciliary body, lens and the two chambers of aqueous humour.
- Anterior septal branches of anterior ethmoidal arteryRami septales anteriores arteriae ethmoidalis anteriorisBranches of the anterior ethmoidal artery that run down the front and upper nasal septum, contributing to the vascular area where nosebleeds arise.
