Specialised structure of plasma membrane

 [A]Microvilli
*The cells of epithelium tissue of small intestine, fold Tu forma finger like structure call microvilli
*It cell contain 3000 of of that.
*Help the small intestine in absorption by increasing its absorption surface area.
[Invegination]
*This type of invegination all fold found in nephron of kidney
*Which type of fold help in absorption of solutes.

 [Tubules]
*Some cell membrane spread into the cytoplasm and former tube like structure called tubule.

 [Desmosome]
*Some part of endoplasmic reticulum store between the intercellular space to form a a tube like structure called desmosome.
*Diameter 200m strome
*The material which store is called desmosome on macula adherens.
*Link between two adjacent cell
*Made up of  mucopolysaccharide and protein

 *Find fibre that is tenofilament or tenofabril came out from desmosome.
*Desmosome can find the epidermis layer of skin
*when the pressure comes from the outside desmosome helps to bound together the cell.

 [Hemidesmosomes]
*Form inside the epithelial tissue of cell membrane
*Made up of collagen
*Help the sale to attached with the basal membrane

 [Interdigitation]
*Between two two adjacent cell membrane finger like projection shown.

 [Tight junction]
*Two cell membrane part is join together in some place storing some material informer junction call tight junction or zonula occludens.
*Blocks intercellular space.
[Gap junction]
*Between two Tu sale echannel form where ions and hormones transfer one cell to another called gap junction.
*Open form food also transfer from one to another sleep.
[Terminal bar]
*Indus mausam region structure that is not attached with any filament call terminal bar.
*Also called zonular adherens

 [Intercellular bridge]
*Two part of different addison cell form a bridge like structure cal intercellular bridge.
*Message transfer from one cell to another very easily,

  Ultrastructure of Nucleus 🟦 Introduction A Nucleus is made up of 4 part *Nuclear membrane or karyotheca *Nucleolus *Nuclear sap or nucleoplasm *Chromatin reticulum or nuclear reticulum 🟦 Nuclear membrane or karyotheca *Karyotheca is a bilayered membrane that surrounded nucleus 🟡 structure- 1)made up of lipoprotein 2) this is the trilaminar membrane 3) diameter 62-90 Å 4) distance between to memories 100-500 Å 5) intermediate space between two membrane is called perinuclear cisternae or perinuclear space. 6) the pores presentation nuclear membrane called nuclear pores 7) diameter of the pores 300-500 Å 8) ribosome and endoplasmic reticulum is is attached to it outer membrane of the nuclear membrane 🟡 Nuclear pore- ~nuclear pore is a complex structure. ~part of the pore is diaphragm, septum, plug or nucleoplasmin and various annuli. ~annulus is a circular part that covers the nuclear pores. ~a pore with annulus called pore complex. ~so

Cell Membrane   *Nageli and Cramer first discover cell membrane in 1855 *Plowe named the cell membrane in 1931. Origin - The outer layer of cytoplasm converted into cell membrane Appearance - *Observe under electron microscope as trilaminar means it has three layer *Outer and inner part is is electron dense layer or dark layer *Middle part is electron less layer or transparent layer. Structure of cell membrane- *Gorter & Grendel-1926- 2 layerd lipid-protein model  *Danielli(1935) & Schmitt (1940)-3 layerd protein lipid model *Daneielli & Davison (1934,52,70) -2 layed lipid surrounded with 2 layed protein layerd *Robertson(1959) protein-lipid-protein,3 layed unit membrane. Composition *Lipids(20-79%) *Protein (20-70%) *Carbohydrate (1-5%) *water(20%)  Example:RBC Protein-52% Lipids-40% Important component of plasma membrane *Lipids- Phospholipid, sterol, cholesterol, glycolipid spingolipid,etc *Carbohydrates- Branche

Malnutrition free India

Dream India,A Malnutrition-free India C hildrens are the ultimate investment of future.If we want to develop India, want some progress in near and far future,we must need to secure the health condition of newborns as well as their moms too. Even with a large development in education, mass production, media development, and in many more basic needs, we can't uplift a society without deleting the malnutrition stigma from our society.   Government have 1st time though about that in 1975 by introducing a plan called mid day meal scheme. But that was not enough. Even now India is witnessing  a large extent of under nutrition babies.   The main cause of this phenomena with not getting required nutrition in pregnancy to the mother. During pregnancy there are lots of family who can't effort or not willing to provide a proper diet to the pregnant one as well as the new born. As a result malnutrition and some vitamin deficiency occur. Vit A deficiency can increase measle
