Connection (and difference) between buccal membrane and buccopharyngeal membrane
A Tale of Two Tissues Prepare yourself for a thrilling journey into the world of microscopic membranes! Today, we’re diving deep into the oral cavity to explore the buccal membrane and its embryonic cousin, the buccopharyngeal (aka oropharyngeal) membrane. It’s a story of similarities, d
embryonic intrigue that’ll make your buccopharyngeal membrane quiver with excitement!
Picture, if you will, the humble beginnings of life, where a thin membrane known as the buccopharyngeal membrane (or oropharyngeal membrane for those who like their words extra fancy) plays the role of the ultimate gatekeeper between the primitive mouth and pharynx. It’s like nature’s ve
Sex-determining region Y proteinĀ (SRY), orĀ testis-determining factorĀ (TDF)
Sex-determining region Y protein (SRY), or testis-determining factor (TDF), is a DNA-binding protein (also known as gene-regulatory protein/transcription factor) encoded by the SRY gene that is responsible for the initiation of male sex determination 
Steroidogenic factor 1Ā (SF-1)Ā 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 related to the reproductive glands or gonads and adrenal glands. This protein is encoded by the NR5A
Structure of DNA repair protein XRCC4Ā akaĀ X-ray repair cross-complementing protein 4
XRCC4 protein is aĀ TETRAMER that resembles the shape of a DUMBBELL containing two globular ends separated by a long, thin stalk. The tetramer is composed of twoĀ dimers, and each dimer is made up of two similarĀ subunits. The first subunit (L) contains amino acid residues 1 ā 203 and has a longer
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 theĀ human embryo, theĀ vitelline duct, also known as theĀ vitellointestinal duct,Ā theĀ yolk stalk,Ā theĀ omphaloenteric duct,Ā or theĀ omphalomesenteric duct,Ā is a long narrow tube that joins theĀ yolk sacĀ to theĀ midgutĀ lumenĀ of the developingĀ fetus.Ā It appears at the end of the fourth w
A Mad Scientist’s Dream – Rumpless Chickens (and more)
Today, we delve into the bizarre phenomenon of rumpless chickensāa feathered marvel characterized by caudal dysplasia, or as some like to call it, the ultimate chicken makeover! These quirky birds are missing their pygostyle, that charming little appendage known as the āparsonās nose,ā a mut
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 have reported that prenatal exposure to APAP results in developmental alterations in both the reproductive tract and th
AgrinĀ is a largeĀ chimeric proteoglycan, a heparan sulfate and chondroitin proteoglycan,Ā whose best-characterised role is in the development of theĀ neuromuscular junctionĀ duringĀ 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 directs the aggregation of acetylcholine receptors (AChR) and acetylcholinesterase (AChE) at synaptic
Cleavage (embryology)
InĀ embryology,Ā cleavageĀ is the division ofĀ cellsĀ in the earlyĀ development of the embryo, followingĀ fertilization.Ā TheĀ zygotesĀ of many species undergo rapidĀ cell cyclesĀ with no significant overall growth, producing a cluster of cells the same size as the original zygote. The different cel
Vitellin is essential in the fertilization process, and embryonic development in egg-laying organisms
VitellinĀ is a protein found in theĀ egg yolk. It is a phosphoprotein.Ā Vitellin is a generic name for major of many yolk proteins. Vitellin has been known since the 1900s.Ā The periodic acid-Schiff method and Sudan black B dye was used to help determine that Vitellin is a glycolipoprotein because i
Opioid growth factor receptor
Opioid growth factor receptor, also known as OGFr or the Ī¶-opioid receptor, is a protein which in humans is encoded by the OGFR gene. The protein encoded by this gene is a receptor for opioid growth factor (OGF), also known as [Met(5)]-enkephalin. T
Pulmonary neuroendocrine cells
Neuroendocrine cellsĀ are cells that receive neuronal input (throughĀ neurotransmittersĀ released by nerve cells or neurosecretory cells) and, as a consequence of this input, release messenger molecules (hormones) into the blood. In this way they bring about an integration between theĀ nervous syste
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.Ā In addition, mice which lack one functional copy (allele) of both the CBP and p300 genes (i.e. areĀ heterozygousĀ for both CBP and p300) a
Cadherin-1
Cadherin-1Ā orĀ Epithelial cadherin(E-cadherin), (not to be confused with theĀ APC/C activator protein CDH1) is aĀ proteinĀ that in humans is encoded by theĀ CDH1gene.[5]Ā Mutations are correlated withĀ gastric,Ā breast, colorectal, thyroid, and ovarian cancers. CDH1 has also been designated asĀ CD3
