Label	Id	Description
primitive knot	UBERON_0003062	[organizer for gastrulation in vertebrates. The primitive knot starts as a regional knot of cells that forms on the blastodisc immediately anterior to where the outer layer of cells will begin to migrate inwards - an area known as the primitive streak. Posterior to the node is the primitive pit, where the cells of the epiblast (the upper layer of embryonic cells) initially begin to invaginate. This invagination expands posteriorly into the primitive groove as the cells layers continue to move into the space between the embryonic cells and the yolk. This differentiates the embryo into the germ layers - endoderm, mesoderm, and ectoderm. The primitive knot migrates posteriorly as gastrulation proceeds, eventually being absorbed into the tail bud.[WP]. the regional thickening of cells at the rostral tip of the vertebrate primitive streak through which gastrulating cells migrate anteriorally to form tissues in the future head and neck; this region organizes the formation of the three embryonic layers and establishes the longitudinal axis and the polarity of the embryo[MP].]

alar plate midbrain	UBERON_2001357
midbrain	UBERON_0001891	[The midbrain is the middle division of the three primary divisions of the developing chordate brain or the corresponding part of the adult brain (in vertebrates, includes a ventral part containing the cerebral peduncles and a dorsal tectum containing the corpora quadrigemina and that surrounds the aqueduct of Sylvius connecting the third and fourth ventricles)[GO].]
obsolete pineal complex	UBERON_2001359
obsolete regional part of septum	UBERON_0023163
corpus spongiosum of penis	UBERON_0011183	[Corpus spongiosum (also known as corpus cavernosum urethrae in older texts) is the mass of spongy tissue surrounding the male urethra within the penis.]
erectile tissue	UBERON_0008324	[with numerous vascular spaces that may become engorged with blood]
periurethral tissue	UBERON_0009010	[Any portion of tissue that surrounds a urethra.]
intestinal epithelium	UBERON_0001277	[Epithelial layer that lines the intestine.]

auditory ossicle endochondral element	UBERON_0035130
auditory ossicle cartilage element	UBERON_0035131

ventral tubercle of humerus	UBERON_0011187	[The greater tubercle of the humerus is situated lateral to the head of the humerus and posteriolateral to the lesser tubercle. Its upper surface is rounded and marked by three flat impressions. the highest of these gives ('superior facet') insertion to the Supraspinatus the middle ('middle facet') to the Infraspinatus. the lowest one ('inferior facet'), and the body of the bone for about 2.5 cm. below it, to the Teres minor. The lateral surface of the greater tubercle is convex, rough, and continuous with the lateral surface of the body. Between the greater tubercle and the lesser tubercle is the intertubercular sulcus (bicipital groove).]
tubercle	UBERON_0005813	[A round nodule, small eminence, or warty outgrowth found on bones, skin, or within the lungs in tuberculosis. They are also found on the leading edge of Humpback Whale's flippers, improving fluid flow over the flipper's surface[WP].]
