Mnemonic:
- Larger the alphabets, larger the diameter (V>F>B)
- Diameters with “sub” prefix are smaller than counterpart without it.
Mnemonic: MTP (Medical Termination of Pregnancy) in increasing order.
The pituitary gland (hypophysis cerebri) is derived from 2 sources. The anterior lobe is an upgrowth of ectoderm from the roof of the stomodeum (primitive buccal cavity), while the posterior lobe is a down growth of neuroectoderm from the diencephalon. 4th week: a diverticulum, Rathke’s pouch, grows upwards from the roof of the stomodeum towards the…
Hepatitis B surface antigen (HBsAg) Appears during incubation period (1-6 months), 2-7 weeks prior to symptoms. Peaks when the patient is most ill. Becomes undetectable in 3-6 months. Indicates infection – recent or chronic. Hepatitis B surface antibody (anti-HBs or HBsAb) Arises once the acute disease has resolved. Sometimes, not…
A: Autosomal dominant C: “Champange glass” pelvis in X-rays H: Hypotonia O: Ossification affected (Enchondral > Appositional) N: Nasal bridge small D: Disproportionate Dwarfism R: Rhizomelic (proximal i.e. humerus and femur shortening) O: Out knees (varus deformity) P: Proliferative zone quantitative defect L: Little phalanx (brachydactyly) and metacarpals with Leister…
Very useful information
why is submentovertical diameter less than mentovertical
Because it is measured from a closer point to the back of the head.
Bcz it is made by God n we can not change it
submento is from the side of the chin to vertex.so that is why it is smaller than mento vertical.
Pic is informative, could have been more clear graphically
