Anatomy, Head

Anatomical Model Showing The Internal Structures Of An Adult Human Head And Neck Left Lateral Median Cutaway View. The Head Skeleton In Beige Includes The Skull Bones And The Facial Architecture. For A Global Description Of The Head, See Image No. 1140405; For A Full Description Of The Vertebral Structures Seen Here, See The Caption Of Image No. 1140405; For Details Of The Anatomy Of The Mouth And Pharynx, See Image No. 1140505. Within The Skull, The Brain, Or Encephalon, Is Protected By The Meninges, Composed Of Three Membranes: The Dura Mater, The Arachnoidea And The Pia Mater. The Nourishing Cerebrospinal Fluid In Blue Circulates Within The Subarachnoid Space, Located Between The Arachnoidea And The Pia Mater. The Encephalon Is Made Up Of The Diencephalon Ii, Covered By The Cerebrum I, Flesh Colored. The Cerebellum 3, In Brown And The Brain Stem In White Lie Under The Cerebrum In The Posterior Area. The Latter Stems Off Into The Spinal Cord, Which Follows Through A Central Canal, Carrying Nerve Impulses Throughout The Organism. The Brain Is Divided By A Longitudinal Fissure Into Two Hemispheres, Each Of Which Is Composed Of Four Lobes The Frontal Lobe Anterior, On The Left The Image, Parietal Lobe Superior, Temporal Lobe Lateral And Occipital Lobe Posterior. The Corpus Callosum 4, In White, A Wide Strip Of White Matter, Links The Two Hemispheres And Anatomically Separates The Cerebrum From The Diencephalon. It Is Made Up Of Four Regions: The Rostrum A, The Genu B, The Body Middle Third And The Splenium Posterior Portion. Ventral To The Corpus Callosum, The Septum Lucidum 5, Flesh Colored Is A Thin Membrane Separating The Lateral Ventricles, Two Of The Four Cerebral Cavities Filled With Cerebrospinal Fluid In Blue. The Third Ventricle Is Connected To Them Through The Interventricular Foramen 11. Cerebrospinal Fluid Is Produced In The Choroid Plexus, Consisting Of Fo (Photo By BSIP/UIG Via Getty Images)
