Connection (and difference) between buccal membrane and buccopharyngeal or oropharyngeal membrane (Copilot)
Copilot says: The buccal membrane and the buccopharyngeal (or oropharyngeal) membrane are both important structures in the oral cavity, but they serve different functions and are l
The region where the crescentic masses of the ectoderm and endoderm come into direct contact with each other constitutes a thin membrane, the buccopharyngeal membrane (or oropharyngeal membrane), which forms a septum between the primitive mouth and pharynx.
In front of the buccopharyngeal area, where the lateral crescents of mesoderm fuse in the middle line, the pericardium is afterward developed, and this region is therefore desi
Sex-determining region Y protein (SRY), or testis-determining factor (TDF)
Sex-determining region Y protein (SRY), or testis-determining factor (TDF), is a DNA-binding protein (also known as gene-regulatory protein/transcription f
DAX1
DAX1 (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1) is a nuclear receptor protein that in humans is encoded by the NR0B1 gene (n
Steroidogenic factor 1 (SF-1) protein and a few related things
The steroidogenic factor 1 (SF-1) protein is a transcription factor involved in sex determination by controlling the activity of genes relat
Structure of DNA repair protein XRCC4 aka X-ray repair cross-complementing protein 4
XRCC4 protein is a TETRAMER that resembles the shape of a DUMBBELL containing two globular ends separated by a long, thin stalk. The tetramer is composed of two dimers, and each
Vitelline duct connects the yolk sac to the small intestine. This duct obliterates when the embryo is about 6 weeks old. Complete failure of the duct to obliterate results in a fistula from the ileum to the umbilicus (vitelline fistula).
In the human embryo, the vitelline duct, also known as the vitellointestinal duct, the yolk stalk, the omphaloenteric duct, or the omphalomesenteric duct, is a long narro
Rumplessness, pygostyles and more
Rumpless chickens are characterised by caudal dysplasia, the absence of the pygostyle or caudal appendage – the “parson’s nose”. This is the
Prenatal exposure to paracetamol/acetaminophen and precursor aniline impairs masculinisation of male brain and behaviour
Paracetamol/acetaminophen (N-Acetyl-p-Aminophenol; APAP) is the preferred analgesic for pain relief and fever during pregnancy. It has therefore caused concern that several studies
Agrin is a large chimeric proteoglycan, a heparan sulfate and chondroitin proteoglycan, whose best-characterised role is in the development of the neuromuscular junction during embryogenesis
Agrin was originally found in the electric organ of Tarpedo california and in the basal lamina at the neuromuscular junction as a protein that di
Cleavage (embryology)
In embryology, cleavage is the division of cells in the early development of the embryo, following fertilization. The zygotes of many species undergo rapid cell cycles
Vitellin is essential in the fertilization process, and embryonic development in egg-laying organisms
Vitellin is a protein found in the egg yolk. It is a phosphoprotein. Vitellin is a generic name for major of many yolk proteins. Vitellin has been known since the 1900s. The pe
Opioid growth factor receptor
Opioid growth factor receptor, also known as OGFr or the ζ-opioid receptor, is a protein which in humans is encoded by the OGFR gene. The protei
Pulmonary neuroendocrine cells
Neuroendocrine cells are cells that receive neuronal input (through neurotransmitters released by nerve cells or neurosecretory cells) and, as a consequence of this input, relea
CBP and p300 are critical for normal embryonic development
Mouse models CBP and p300 are critical for normal embryonic development, as mice completely lacking either CBP or p300 protein, die at an early embryonic stage. In addition, mice
Cadherin-1
Cadherin-1 or Epithelial cadherin(E-cadherin), (not to be confused with the APC/C activator protein CDH1) is a protein that in humans is encoded by the CDH1gene.[5] Mutation
