The Anthromica Library
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.

- Posterior commissureCommissura posteriorA rounded band of crossing white fibres at the back of the third ventricle, just above the entrance to the cerebral aqueduct.
- Posterior quadrangular lobuleLobulus quadrangularis posteriorA lobule on the upper surface of each cerebellar hemisphere, lying just behind the primary fissure at the front of the posterior lobe.
- Posterior transverse collateral sulcusA short, variable groove on the inferior surface of the occipital lobe, crossing the territory near the back end of the collateral sulcus.
- Precentral gyrusGyrus precentralisThe convolution at the back of the frontal lobe, in front of the central sulcus, that holds the primary motor cortex.
- PrecuneusThe square-shaped area of parietal cortex on the inner surface of each hemisphere, just in front of the occipital cuneus.
- PutamenThe large rounded outer nucleus of the basal ganglia, lying deep in each cerebral hemisphere between the external and internal capsules.
- Pyramid of medulla oblongataPyramis medullae oblongataeA paired ridge on the front of the medulla oblongata, carrying the descending corticospinal and corticobulbar fibres beside the midline.
- Pyramis of vermisPyramis vermisA part of the inferior vermis of the cerebellum, between the tuber above and the uvula below, flanked by the biventral lobules.
- Red nucleusNucleus ruberAn oval, pinkish nucleus in the tegmentum of the upper midbrain, a relay between cerebellum, motor cortex and spinal cord.
- Septal nucleiNuclei septalesA group of grey matter nuclei in the septal area below the front of the corpus callosum, linked to the hippocampus, hypothalamus and habenula.
- Septum pellucidumA thin, vertical, two-layered partition in the brain's midline that separates the front horns of the two lateral ventricles.
- Straight gyrus (Gyrus rectus)The narrow, straight convolution along the medial edge of the underside of the frontal lobe, beside the longitudinal fissure.
- Stria medullaris thalamiA slender band of white fibres along the upper medial edge of the thalamus, running back to the habenula in the epithalamus.
- Stria terminalisA curved band of fibres running from the amygdala along the floor of the lateral ventricle, in the groove between the caudate nucleus and thalamus.
- Subparietal sulcusSulcus subparietalisA groove on the inner face of each hemisphere above the splenium, separating the precuneus from the posterior cingulate gyrus.
- Superior cerebellar pedunclePedunculus cerebellaris superiorA paired band of white matter that joins the cerebellum to the midbrain, carrying most of the cerebellum's output upward.
- Superior colliculusColliculus superiorOne of the paired upper mounds on the midbrain roof, a layered centre that turns eyes and head towards things seen and heard.
- Superior frontal gyrusGyrus frontalis superiorThe uppermost convolution of the frontal lobe, running front to back beside the longitudinal fissure and onto the medial surface.
- Superior frontal sulcusSulcus frontalis superiorA long groove on the outer surface of the frontal lobe that separates the superior frontal gyrus from the middle frontal gyrus.
- Superior occipital gyriGyri occipitales superioresThe upper convolution on the outer surface of the occipital lobe, lying above the intraoccipital sulcus and close to the midline.
- Superior parietal lobuleLobulus parietalis superiorThe upper part of the parietal lobe behind the postcentral gyrus, above the intraparietal sulcus, used for spatial awareness and reaching.
- Superior salivatory nucleusNucleus salivatorius superiorA small parasympathetic nucleus in the pontine tegmentum whose fibres travel in the facial nerve to the tear, nasal and salivary glands.
- Superior semilunar lobuleLobulus semilunaris superiorA large lobule on the upper and back part of each cerebellar hemisphere, lying just above the horizontal fissure.
- Superior temporal gyrus (Lateral part)The exposed outer face of the superior temporal gyrus, the top convolution of the temporal lobe just below the lateral sulcus.
