blastoderm
|
UBERON_0004750 |
[A layer of cells formed at one pole of macrolecithal eggs such as the yolky egg of birds. The yolk prevents the division from taking place through the egg, resulting in meroblastic cleavage during the many cleavage divisions. At the animal pole (containing less yolk than the vegetal pole), the zygote divides and subdivides, forming the blastoderm, which gradually spreads around the yolk and forms the embryo. The blastoderm is composed of two layers, the epiblast and the hypoblast, which enclose the fluid-filled blastocoel cavity.] |
|
scapulocoracoid
|
UBERON_0004753 |
[Skeletal element that consists of the scapula and the coracoid[VSAO, modified].] |
|
palatoquadrate cartilage
|
UBERON_0004752 |
[The dorsal component of the mandibular arch.] |
|
obsolete autopalatine
|
UBERON_0004748 |
|
|
supraoccipital bone
|
UBERON_0004747 |
[Endochondral bone that is located at the dorsal part of the occipital region of the cranium or the dorso-posterior part of the skull[TAP,modified].] |
|
supraoccipital endochondral element
|
UBERON_0015015 |
[A supraoccipital bone or its cartilage or pre-cartilage precursor.] |
|
blastodisc
|
UBERON_0004749 |
[A small, circular, white spot (approximately 2-3 mm across) on the surface of the yellow yolk of an egg that has been laid. The nucleus of the egg is in the germinal disc.] |
|
gland of anal canal
|
UBERON_0004760 |
[A gland that is part of an anal canal [Automatically generated definition].] |
|
limb
|
UBERON_0002101 |
[A paired appendage that is evolved from a paired fin. The extent of this structure includes autopod, stylopod and zeugopod regions when present, but excludes the girdle and its parts.] |
|
visual system
|
UBERON_0002104 |
[The sensory system subserving the sense of vision.] |
|
vestibulo-auditory system
|
UBERON_0002105 |
[Sensory system responsible for the perception of spatial orientation and auditory stimuli.] |
|
spleen
|
UBERON_0002106 |
[The organ that functions to filter blood and to store red corpuscles and platelets.] |
|
vomerine tooth
|
UBERON_0004767 |
[A tooth that is on the vomer.] |
|
palatal tooth
|
UBERON_0012070 |
[A tooth that is on the roof of the mouth.] |
|
caudal anterior cingulate cortex
|
UBERON_0028715 |
[Component of the cingulate cortex. The rostral boundary was the first appearance of the genu of the corpus callosum whereas the caudal boundary was established as the first appearance of the mammillary bodies. The medial boundary was the medial aspect of the cortex. The supero-lateral boundary was the superior frontal gyrus whereas the infero-lateral boundary was the corpus callosum (Christine Fennema-Notestine).] |

|
|
cartilaginous neurocranium
|
UBERON_0004761 |
[The primitive cartilagionous skeletal structure of the fetal skull that grows to envelop the rapidly growing embyonic brain. In humans, the chondrocranium begins forming at 28 days from mesenchymal condensations and is fully formed between week 7 and 9 of fetal development. While the majority of the chondrocranium is succeeded by the bony skull in most higher vertebrates, some components do persist into adulthood.[1] In Cartilagious fishes and Agnathans, the chondrocranium persist throughout life.[2] Embryologically, the chondrocranium represent the basal cranial structure, and lay the base for the formation of the endocranium in higher vertebrates[WP].] |
|
trunk
|
UBERON_0002100 |
[Organism subdivision which is the part of the body posterior to the cervical region (or head, when cervical region not present) and anterior to the caudal region. Includes the sacrum when present.] |
|
intramembranous bone tissue
|
UBERON_0004764 |
[Bone tissue that forms directly within mesenchyme, and does not replace other tissues[TAO]. Intramembranous ossification is the formation of bone in which osteoblasts secrete a collagen-proteoglycan matrix that binds calcium salts and becomes calcified[GO]. Intramembranous ossification is the way flat bones and the shell of a turtle are formed[GO]. Unlike endochondral ossification, cartilage is not present during intramembranous ossification[WP].] |
|
endochondral bone tissue
|
UBERON_0004763 |
[Replacement bone tissue that forms within cartilage[VSAO, modified].] |
