| trapezoid nucleus | The trapezoid body is part of the auditory pathway. It is a bundle of fibers and cells in the pontine tegmentum. It consists of fibers arising from the ventral cochlear nucleus. A collection of nerve cells inside forms a trapezoid nucleus. The superior olivary nucleus is situated on the dorsal surface of the trapezoid body. Most nerve fibers pass directly from the superior olivary nuclei to the inferior colliculus [Wikipedia: http://en.wikipedia.org/wiki/Trapezoid_body]. | trapezoid body |
| cornea | The transparent part of the coat of the eyeball that covers the iris and pupil and admits light to the interior [Brenda]. | — |
| trabecular meshwork | The trabecular meshwork is an area of tissue in the eye located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea) [Wikipedia: http://en.wikipedia.org/wiki/Trabecular_meshwork]. | — |
| sclera | The tough white outer coat of the eyeball, covering approximately the posterior five-sixths of its surface, and continuous anteriorly with the cornea and posteriorly with the external sheath of the optic nerve [Brenda]. | — |
| dura mater | The tough fibrous membrane covering the brain and the spinal cord and lining the inner surface of the skull. It is the outermost of the three meninges that surround the brain and spinal cord [Brenda]. | — |
| thyroid | The thyroid gland or simply, the thyroid (ËθaɪrÉɪd ...), in vertebrate anatomy, is one of the largest endocrine glands. The thyroid gland is found in the neck, below the thyroid cartilage (which forms the laryngeal prominence, or "Adam's apple"). The isthmus (the bridge between the two lobes of the thyroid) is located inferior to the cricoid cartilage [Wikipedia: http://en.wikipedia.org/wiki/Thyroid]. | — |
| thoracic wall | The thoracic wall (or chest wall) is the boundary of the thoracic cavity. The bony portion is known as the thoracic cage. However, the wall also includes muscle, skin, and fascia [Wikipedia: http://en.wikipedia.org/wiki/Thoracic_wall]. | — |
| third ventricle | The third ventricle (ventriculus tertius) is one of four connected fluid-filled cavities comprising the ventricular system within the human brain. It is a median cleft between the two thalami, and is filled with cerebrospinal fluid (CSF) [Wikipedia: http://en.wikipedia.org/wiki/Third_ventricle]. | — |
| diaphragm | The thin muscle below the lungs and heart that separates the chest from the abdomen [Brenda]. | — |
| cerebellum cortex | The thin gray surface layer of the cerebellum, consisting of an outer molecular layer or stratum moleculare, a single layer of purkinje cells (the ganglionic layer), and an inner granular layer or stratum granulosum [Biology-Online: http://www.biology-online.org/dictionary/Cerebellar_cortex]. | cortex cerebelli; cerebellar cortex |
| reticular thalamic nucleus | The thalamic reticular nucleus is part of the ventral thalamus that forms a capsule around the thalamus laterally. However, recent evidence from mice and fish question this statement and define it as dorsal thalamic structure.[1][2] It is separated from the thalamus by the external medullary lamina. Reticular cells are GABAergic, and have discoid dendritic arbors in the plane of the nucleus. Thalamic Reticular Nucleus is variously abbreviated TRN, RTN, NRT, and RT [Wikipedia: http://en.wikipedia.org/wiki/Thalamic_reticular_nucleus]. | thalamic reticular nucleus |
| rectum | The terminal part of the intestine from the sigmoid flexure to the anus [Brenda]. | — |
| premamillary nucleus | The term premammillary nuclei refers to two groups of cells demonstrated by Nissl stain ventrally in the posterior hypothalamic region just rostral to the medial mammillary nucleus. They are the dorsal premammillary nucleus and the ventral premammillary nucleus. They are prominent in the rat (Swanson., 2004) and the mouse (Hof., 2000). Some authors report them also in the macaque (Bleier., 1984), though others indicate that they are represented only by a small group of cells in that species (Crosby., 1962; Paxinos., 2009). They are not detectable by Nissl stain in the human (Saper., 2004) [BrainInfo: http://braininfo.rprc.washington.edu/centraldirectory.aspx?ID=418]. | premammillary nuclei; premammillary nucleus; premamillary nuclei |
| motor | The term motor refers to a muscle, nerve, or center that effects or produces motion [TheFreeDictionary: http://medical-dictionary.thefreedictionary.com/motor]. | — |
| medial mamillary nucleus | The term medial mammillary nucleus refers to a well defined group of cells located ventromedially in the posterior hypothalamic region of the human, macaque, rat and mouse. Defined on the basis of Nissl stain it is the most prominent cell group in the volume bounded by the mammillary body. In the human (Saper., 2004) and the macaque (Paxinos., 2009) it is composed of two parts, the medial part of the medial mammillary nucleus and the lateral part of the medial mammillary nucleus. In the rat (Swanson., 2004) and the mouse (Hof., 2000) it is composed of two different parts: body of the medial mammillary nucleus and median part of the medial mammillary nucleus [BrainInfo: http://braininfo.rprc.washington.edu/centraldirectory.aspx?ID=414]. | medial mammillary nuclei; medial mammillary nucleus; medial mamillary nuclei |
| intermediomedial column | The term intermediomedial cell column refers to a cell column that occupies the medial portion of lamina VII along the central canal of the spinal cord (Anthoney-1994; Carpenter-1983) [BrainInfo: http://braininfo.rprc.washington.edu/centraldirectory.aspx?ID=1668]. | intermediomedial cell column; intermediomedial nucleus; nucleus intermediomedialis |

| cerebral cortex | The surface layer of gray matter of the cerebrum that functions chiefly in coordination of sensory and motor information [Brenda]. | — |
| superior vestibular nuclei | The superior vestibular nucleus (Bechterew's nucleus) is the dorso-lateral part of the vestibular nucleus and receives collaterals and terminals from the ascending branches of the vestibular nerve. Its axons terminate in much the same manner as do those from the lateral nucleus [Wikipedia: http://en.wikipedia.org/wiki/Superior_vestibular_nucleus]. | Bechterew's nucleus |
| superior salivatory nuclei | The superior salivary nucleus (or superior salivatory nucleus) of the facial nerve is a visceromotor cranial nerve nucleus located in the pontine tegmentum. Parasympathetic efferent fibers of the facial nerve (preganglionic fibers) arise according to some authors from the small cells of the facial nucleus, or according to others from a special nucleus of cells scattered in the reticular formation, dorso-medial to the facial nucleus. This is sometimes called the superior salivatory nucleus. These preganglionic fibers are distributed partly via the chorda tympani and lingual nerves to the submandibular ganglion, thence by postganglionic (vasodilator) fibers to the submandibular gland and sublingual gland. Some of the preganglionic fibers travel along the greater petrosal nerve through the pterygoid canal (where they join the postsynaptic fibers of the deep petrosal nerve and are called the Vidian nerve) and synapse in the pterygopalatine ganglion, whereupon the postganglionic, postsynaptic, efferent fibers travel to innervate the lacrimal gland and the mucosal glands of the nose, palate, and pharynx. The term "lacrimal nucleus" is sometimes used to refer to a portion of the superior salivary nucleus [Wikipedia: http://en.wikipedia.org/wiki/Superior_salivary_nucleus]. | superior salivary nucleus |
| superior olivary nucleus | The superior olivary complex (or SOC or superior olive) is a collection of brainstem nuclei that functions in multiple aspects of hearing and is an important component of the ascending and descending auditory pathways. The SOC is intimately related to the trapezoid body: most of the cell groups of the SOC are dorsal (posterior in primates) to this axon bundle while a number of cell groups are embedded in the trapezoid body. Overall, the SOC displays a significant interspecies variation, being largest in bats and rodents and smaller in primates [Wikipedia: http://en.wikipedia.org/wiki/Superior_olivary_complex]. | — |
| subthalamus | The subthalamus is a part of the diencephalon. Its major part is the subthalamic nucleus. Functionally, it also encompasses the globus pallidus, which is topographically part of the telencephalon [Wikipedia: http://en.wikipedia.org/wiki/Subthalamus]. | — |
| substantia nigra | The substantia nigra is located in the mesencephalon (mid brain) region of the brain. It is part of the basal ganglia [Brenda]. | — |
