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.
841–864 of 1303
- Plantar venous archArcus venosus plantarisA deep venous arch across the sole of the foot, lying beside the plantar arterial arch and gathering the plantar metatarsal veins.
- Plantaris muscleMusculus plantarisA small calf muscle behind the knee whose very long, thin tendon runs down between gastrocnemius and soleus to the heel.
- PlatysmaPlatysma is a broad, thin sheet of muscle lying just under the skin of the front and side of the neck, from chest to jaw.
- PleuraThe thin serous membrane that covers each lung and lines the inside of the chest wall, enclosing a slit-like pleural cavity between.
- PonsThe middle part of the brainstem, a broad bulge lying below the midbrain and above the medulla, with the cerebellum behind it.
- Popliteal arteryArteria popliteaThe femoral artery's continuation behind the knee, running through the popliteal fossa to divide below popliteus.
- Popliteal veinVena popliteaThe deep vein behind the knee, formed by the tibial veins and continuing upwards as the femoral vein.
- Popliteofibular ligamentLigamentum popliteofibulareA short, strong band at the back and outer side of the knee joining the popliteus tendon to the fibular head.
- Popliteus muscleMusculus popliteusA thin, triangular muscle in the floor of the popliteal fossa that unlocks the fully straightened knee.
- Postcentral arterial branchArteria sulci postcentralisA cortical branch of the middle cerebral artery that climbs in the postcentral sulcus to supply the postcentral gyrus and front of the parietal lobe.
- Postcentral gyrusGyrus postcentralisThe convolution of the parietal lobe just behind the central sulcus, holding the primary somatosensory cortex for touch and body position.
- Postcentral sulcusSulcus postcentralisThe groove on the parietal lobe that runs behind and parallel to the central sulcus, forming the back edge of the postcentral gyrus.
- Posterior antebrachial cutaneous nerveNervus cutaneus posterior antebrachiiA cutaneous branch of the radial nerve, given in the arm, that supplies a strip of skin down the back of the forearm.
- Posterior auricular veinVena auricularis posteriorA scalp vein that descends behind the ear and joins the retromandibular vein to form the external jugular vein.
- Posterior axillary nodesNodi axillares posteriores nodi subscapularesThe subscapular group of axillary lymph nodes, lying on the posterior wall of the armpit along the subscapular vessels.
- Posterior belly of digastric muscleVenter posterior musculi digastriciThe posterior belly of digastric is the longer rear half of the digastric, running from the mastoid notch forwards to the hyoid.
- Posterior branch of medial antebrachial cutaneous nerveRamus posterior nervi cutanei medialis antebrachiiThe smaller terminal branch of the medial cutaneous nerve of the forearm, supplying skin on the back of the ulnar side of the forearm.
- Posterior branch of obturator nerveRamus posterior nervi obturatoriiThe deep division of the obturator nerve, passing through obturator externus to supply the deep adductors and send a twig to the knee.
- Posterior branch of renal arteryRamus posterior arteriae renalisThe smaller of the two primary divisions of the renal artery, passing behind the renal pelvis to supply the back of the kidney.
- Posterior cells of ethmoid boneCellulae posteriores ossis ethmoideiThe back group of air cells in each ethmoidal labyrinth, lying in front of the sphenoidal sinus and draining into the superior meatus.
- Posterior cerebral arteryArteria cerebri posteriorA terminal branch of the basilar artery that curves round the midbrain to supply the occipital lobe, lower temporal lobe and thalamus.
- Posterior circumflex humeral arteryArteria circumflexa posterior humeriA branch of the third part of the axillary artery that accompanies the axillary nerve across the quadrangular space and round the humeral neck.
- Posterior circumflex humeral veinVena circumflexa posterior humeriA vein that winds around the back of the surgical neck of the humerus with the axillary nerve and drains into the axillary vein.
- Posterior cochlear nucleusNucleus cochlearis posteriorThe layered auditory nucleus on the back and side of the inferior cerebellar peduncle where the pons and medulla meet.
