Germinal Layers
Jul. 17th, 2009 09:29 pmA human embryo starts out as three layers of tissue known as the ectoderm, mesoderm and endoderm. Most of us know, if we know anything about embryology at all, that the ectoderm becomes the nervous system and skin, the mesoderm becomes the bones and muscle, and the endoderm becomes the gut. But let's get more specific.
What layer originates the parenchyma of the tonsils and thymus?
Ectoderm? Mesoderm? or Endoderm??
( Go ahead, guess. You have a one in three chance. )

Pituitary Pathology
May. 24th, 2009 11:06 amWhat does pituitary mean, from the Latin? (think onomatopoeia...)
to spit mucus
ptuo = to spit, pituita = mucus
What do you call a hormone that acts on neighboring cells?
paracrine
Are pituitary hormones steroid, steroid type, or peptide hormones?
peptide, all of them are
What do you call the loss of lateral visual fields?
bitemporal hemianopsia
Damage to what part of the pituitary causes diabetes insipidus, and which hormone is lacking?

The urogenital system develops from urogenital ridges of the intermediate MESODERM. First stage is pronephros. Next is mesonephros, in which primitive nephrons form and produce some urine (as early as 9 weeks gestation) which goes into the gut tube (cloaca) of the pre-human. The MESONEPHRIC DUCT becomes the ductus deferens. The metanephros is the final form of the kidney. It forms when the URETERIC BUD (aka metanephric diverticulum) branches out from the mesonephric duct and forms the collecting system (ureter, calyces, collecting tubules). It signals the surrounding mesenchyme to become the metanephric blastema, which blasts out the rest of the kidney including the rental tubules. Vascular cells migrate into the blastema and form glomeruli.

Curvy Women Have Smarter Kids
Jan. 27th, 2008 01:37 pmI just ran across this article. I haven't really checked the science behind it, but what they are saying is that women with broader hips have fat stores of omega 3 fatty acids in their thighs and butts. Belly fat apparently is lower in omega 3's. The brain is built mostly of lipids. This article says that during child development, the brain of the fetus is built from the reserves of omega 3's that the mother has in her thighs. It says that a skinny pregnant woman can supplement omega 3 fatty acids, but that your body prefers to use stored lipids for building baby brains.

Vocababble: Embryonic Limb Development
Dec. 2nd, 2007 02:10 pmQUIZ YOURSELF
1. What is the first major tissue of the limb to differentiate?
2. How do myotomal cells find their way from the somites to the limb to become muscle?
3. What kind of neurons are formed from neural crest cells?
4. What kind of cells migrate medially from the axis to form vertebrae and ribs?
5. What does AER stand for?
6. What (the heck) does the AER do and why?
( answers and vocab )
