Label	Id	Description
definitive endoderm	UBERON_0005439
clivus of occipital bone	UBERON_0004108	[Part of the cranium, the clivus is a shallow depression behind the dorsum sellC& that slopes obliquely backward. It forms a gradual sloping process at the anterior most portion of the basilar occipital bone at its junction with the sphenoid bone. On axial planes, it sits just posterior to the sphenoid sinuses. Just lateral to the clivus bilaterally is the foramen lacerum which contains the internal carotid artery, proximal to its anastamosis with the Circle of Willis. Posterior to the clivus is the basilar artery. The clivus supports the upper part of the pons.]
head of femur	UBERON_0006767	[The hemispheric articular surface at the upper extremity of the thigh bone[Stedman, 26th ed]. The femur head is the highest part of the thigh bone. It is supported by the neck of the femur. The head is globular and forms rather more than a hemisphere, is directed upward, medialward, and a little forward, the greater part of its convexity being above and in front. Its surface is smooth, coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis femoris, which is situated a little below and behind the center of the head, and gives attachment to the ligament of head of femur. If there is a fracture of the neck of the femur, the blood supply through the ligament becomes crucial. In orthopedic surgery, the head of the femur is important because it can undergo avascular necrosis and consequent osteochondritis dissecans. The head is removed in total hip replacement surgery [WP].]
epiphyseal line	UBERON_0006768
conus medullaris	UBERON_0005437	[The conus medullaris is the terminal end of the spinal cord. It occurs near lumbar vertebral levels 1 (L1) and 2 (L2). After the spinal cord tapers out, the spinal nerves continue as dangling nerve roots called cauda equina. This terminal nerve root tail is referred to as the filum terminale. The upper end of the conus medullaris is usually not well defined.]
UBERON_0004102	UBERON_0004102
right anterior vena cava	UBERON_0006766
upper part of cisterna chyli	UBERON_0005435	[A dilated sac at the lower end of the thoracic duct into which lymph from the intestinal trunk and two lumbar lymphatic trunks flow.]
nasolabial region	UBERON_0004101	[.]
hairline	UBERON_0004104	[Anatomical line demarcating the boundary between forehead and scalp.]
epithelium of conjunctiva	UBERON_0006763	[Layer of nonkeratinized squamous epithelium lining the conjunctiva, overlying scleral tissue]
anterior communicating artery	UBERON_0006764	[A blood vessel of the brain that connects the left and right anterior cerebral arteries. The anterior communicating artery connects the two anterior cerebral arteries across the commencement of the longitudinal fissure. Sometimes this vessel is wanting, the two arteries joining together to form a single trunk, which afterward divides; or it may be wholly, or partially, divided into two. Its length averages about 4 mm, but varies greatly. It gives off some of the anteromedial ganglionic vessels, but these are principally derived from the anterior cerebral artery. It is part of the cerebral arterial circle, also known as the circle of Willis.]
obsolete peripheral part of autonomous nervous system	UBERON_0005433
dorsal pancreatic duct	UBERON_0005429	[A pancreatic duct that develops from the dorsal pancreatic bud.]
tibiofibula	UBERON_0006714	[Paired, endochondral bones formed by the fusion of the tibia and fibula. They form the shanks, extending from the knees to the ankles.]
foramen cecum of frontal bone	UBERON_0006713	[The frontal crest of the frontal bone ends below in a small notch which is converted into a foramen, the foramen cecum, by articulation with the ethmoid. This foramen varies in size in different subjects, and is frequently impervious; when open, it transmits a vein from the nose to the superior sagittal sinus. This has clinical importance in that infections of the nose and nearby areas can be transmitted to the meninges and brain from what is known as the danger triangle of the face.]
spiral ligament	UBERON_0006725	[A spiral thickening of the fibrous lining of the cochlear wall. Spiral ligament secures the membranous cochlear duct to the bony spiral canal of the cochlea. Its spiral ligament fibrocytes function in conjunction with the stria vascularis to mediate cochlear ion homeostasis.]
osseus spiral lamina	UBERON_0006724	[The osseous spiral lamina is a bony shelf or ledge which projects from the modiolus into the interior of the canal, and, like the canal, takes two-and-three-quarter turns around the modiolus. It reaches about half-way toward the outer wall of the tube, and partially divides its cavity into two passages or scalae, of which the upper is named the scala vestibuli, while the lower is termed the scala tympani.]
pterygoid muscle	UBERON_0006720
medial pterygoid muscle	UBERON_0006718	[The medial pterygoid is a pharyngeal arch 1 muscle that participates in oral/pharyngeal behaviors and is innervated by the nerve to the medial pterygoid and attaches to the cranial base and the medial side of the mandibular angle.]
