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.
721–744 of 1303
- NeurohypophysisThe neural back lobe of the pituitary gland and its stalk, which store and release vasopressin and oxytocin made in the hypothalamus.
- Node of arch of azygos veinNodus arcus venae azygosA lymph node of the right side of the mediastinum, lying beside the arch of the azygos vein above the right main bronchus.
- Node of ligamentum arteriosumNodus ligamenti arteriosiA lymph node of the superior mediastinum lying beside the ligamentum arteriosum, between the arch of the aorta and the left pulmonary artery.
- Nodule of vermisNodulus vermisThe front end of the inferior vermis, jutting into the fourth ventricle's roof and forming the midline part of the flocculonodular lobe.
- Nuchal ligamentLigamentum nuchaeA midline fibrous septum in the nape, running from the occipital bone to the spine of the seventh cervical vertebra.
- Nuclei pulposiThe soft, water-rich cores of the intervertebral discs, from the C2-C3 disc down to the lumbosacral disc, that spread load between the vertebrae.
- Nucleus ambiguusA column of motor neurons deep in the lateral medulla that drives the muscles of the palate, pharynx and larynx and slows the heart.
- Nucleus of abducens nerveNucleus nervi abducentisA motor nucleus in the lower pons beneath the fourth ventricle that drives the lateral rectus and coordinates sideways gaze of both eyes.
- Nucleus of accessory nerveNucleus nervi accessoriiA column of motor neurons in the upper cervical spinal cord whose axons form the accessory nerve to sternocleidomastoid and trapezius.
- Nucleus of hypoglossal nerveNucleus nervi hypoglossiA column of motor neurons near the midline of the medulla, under the fourth ventricle, whose axons form the hypoglossal nerve to the tongue.
- Nucleus of oculomotor nerveNucleus nervi oculomotoriusThe main motor nucleus of the third cranial nerve, a paired cell column in the upper midbrain that moves most eye muscles.
- Nucleus of solitary tractNucleus tractus solitariiA long sensory nucleus in the dorsal medulla that receives taste and visceral information through the seventh, ninth and tenth cranial nerves.
- Nucleus of trochlear nerveNucleus nervi trochlearisA small motor nucleus in the lower midbrain whose axons cross and leave the back of the brainstem as the trochlear nerve to superior oblique.
- Nucleus propriusA layer of grey matter in the head of the posterior horn, just deep to the substantia gelatinosa, made up of Rexed laminae III and IV.
- Oblique cordChorda obliquaA small flat ligament in the upper forearm, passing from the ulnar tuberosity down and outwards to the radius just below its tuberosity.
- Oblique head of adductor hallucisCaput obliquum adductoris hallucisThe larger, deeper head of adductor hallucis, slanting across the sole from the middle metatarsal bases to the great toe.
- Oblique head of adductor pollicisCaput obliquum adductoris pollicisThe oblique head of adductor pollicis is the upper part of the thumb adductor, arising from the central bones at the base of the palm.
- Oblique part of cricothyroid musclePars obliqua musculi cricothyreoideiThe oblique part is the rear, more horizontal set of cricothyroid fibres, running from the cricoid arch to the thyroid cartilage's lower horn.
- Oblique popliteal ligamentLigamentum popliteum obliquumA broad, flat band crossing the back of the knee capsule, formed as an expansion of the semimembranosus tendon.
- Obliquus inferior capitis muscleMusculus obliquus inferior capitisObliquus capitis inferior is a thick suboccipital muscle joining the spine of the axis to the atlas and turning the head.
- Obliquus superior capitis muscleMusculus obliquus superior capitisObliquus capitis superior is a small suboccipital muscle running up and back from the atlas to the occipital bone.
- Obturator arteryArteria obturatoriaA paired pelvic artery, usually from the internal iliac, that runs along the side wall of the pelvis and leaves it through the obturator canal for the medial thigh.
- Obturator externusA flat, fan-shaped muscle covering the outside of the obturator membrane and running behind the femoral neck to the trochanteric fossa.
- Obturator internusA fan-shaped muscle lining the side wall of the lesser pelvis, whose tendon turns out through the lesser sciatic foramen to the greater trochanter.
