pedunculopontine tegmental nucleus	UBERON_0002142	[The pedunculopontine nucleus (PPN) (or pedunculopontine tegmental nucleus, PPTN) is located in the brainstem, caudal to the substantia nigra and adjacent to the superior cerebellar peduncle. It is composed by a wide variety of neurochemical cell types, including cholinergic, glutamatergic and GABAergic cells. In the classical sense, the PPN is considered to be one of the main components of the reticular activating system. [WP,unvetted].]
reticulotegmental nucleus	UBERON_0002147	[The tegmental pontine reticular nucleus (or pontine reticular nucleus of the tegmentum) is an area within the floor of the midbrain. This area is known to affect the cerebellum with its axonal projections. These efferent connections have been proven to project not only ipsilaterally, but also to decussate and project to the contralateral side of the vermis. It has also been shown that the projections from the tegmenti pontis to the cerebellar lobes are only crossed fibers. The n.r. tegmenti pontis also receives afferent axons from the cerebellum. This nucleus is known for its large amount of multipolar cells and its particularly reticular structure. The n.r. tegmenti pontis is topographically related to pontine nuclei (non-reticular), being just dorsal to them. The nucleus reticularis has been known to mediate eye movements, otherwise known as so-called saccadic movement. This makes sense concerning their connections as it would require a nucleus which receives and projects to the cerebellum to mediate that kind of complex circuitry. Also, behaviorally this makes sense as no one thinks about saccadic movements when scanning a room and the saccadic movements are not directly controlled by the cortex. The nuclei of the cerebellum are the most traditionally studied mostly because it is easy to see which nuclei degrade when the cerebellum is amputated. The neurons of the lateral reticular formation are very important for reflexes and the mediation of posture. It has been shown in cats that electrical stimulation of the reticular formation can make a standing cat lie down. Conversely if the cat is stimulated in an alternate spot it can make a lying cat stand.]
vein of lower lip	UBERON_0003478	[The inferior labial vein is the vein receiving blood from the lower lip.]
vein of lip	UBERON_0013136	[A vein that drains a lip.]
dorsal tegmental nucleus	UBERON_0002143
ureteric vein	UBERON_0003475	[A vein that is part of a ureter [Automatically generated definition].]
peripeduncular nucleus	UBERON_0002144	[A group of neuron cell bodies that form a thin, caplike configuration over the dorsolateral aspect of the crus cerebri; many of its cells are acetylcholinesterase positive.]
vein of upper lip	UBERON_0003477	[The inferior labial vein is the vein receiving blood from the upper lip.]
interpeduncular nucleus	UBERON_0002145
anterior lingual gland duct	UBERON_0015445	[A duct that is part of a anterior lingual gland.]
vein of trabecular bone	UBERON_0003482	[A portion of vein that is part of a trabecular bone tissue [Automatically generated definition].]
pontine nuclear group	UBERON_0002151	[Nuclei in the basal pons, intermingled among the descending axons from the cortex, that receive neocrotcial input and give rise to many axons that cross the midline to enter the contralateral cerebellum (Butler and Hodos, Comparative Vertebrate Neuroanatomy, 2nd ed., 2005, pg 135)]
eye sebaceous gland	UBERON_0003484	[A sebaceous gland that is part of a camera-type eye. Example: a tarsal gland.]
eye skin gland	UBERON_0003605	[A skin gland that is part of a camera-type eye [Automatically generated definition].]
skin sebaceous gland	UBERON_0003487	[A holocrine gland of the dermis that secretes sebum into hair follicles.]
thymus lymphoid tissue	UBERON_0003483	[A portion of lymphoid tissue that is part of a thymus [Automatically generated definition].]
fastigial nucleus	UBERON_0002153	[the most medial of the cerebellar nuclei; it receives its afferent input from Purkinje cells of the flocculonodular lobe and the vermis, and most of its efferent connections travel via the inferior cerebellar peduncle to the vestibular nuclei and to the medullary reticular formation]
