WHAT are the secrets of the human cell? (3)

Slim nerve cells that are more than 3 feet long and about 1/40,000th of an inch wide, transmit impulses between the body-cells and the brain-cells.  

Red blood cells , sculpted like poker chips and 3/10,000th of an inch in diameter, carry life giving oxygen around the body.

Researchers remain baffled by the innate intelligence of the body using chemical mechanisms that enable particular genes in different cells to switch themselves on and off and perform differently in varying circumstances.

WHAT are the secrets of the human cell? (2)

Scientists discovered three centuries ago that living things contain cells and it is only in the last eight decades that they have begun to piece together the puzzle of how cells operate.

They know a few fundamental things:  every single adult cell (except ova and sperm) contains the same set of genes as the original cell.  Still, cells come in all shapes, sizes and functions.

How do you account for  that feat?

Secret of the human cell (5)

The human cell and its organelles or interior parts still guard many secrets.  Scientists want to know most of all, what mechanism causes the process known as “cell regulation“, why certain cells in the pancreas produce insulin, others supply muscles with their power and still others serve the thousands of remaining bodily needs.

How do the outer skins or membranes of the cell cooperate with the genes to repel invaders while allowing necessary chemicals and food supplies to move in and out?

What controls how genes transmit their instructions for creating vital chemicals in the cells’ “factories” or ribosomes?

What would be YOUR answers to these questions?

Secrets of the human cell? (2)

Scientists discovered three centuries ago that living things contain cells and it’s only within the last five decades that they have begun to piece together the puzzle of how cells operate.  They know a few fundamental things:

Every single adult cell (except ova and sperm) contains the same set of genes as the original parent cell.  Still, cells come in all shapes, sizes and functions: slim nerve cell, more that 3 feet long and about 1/40,000th of an inch wide, transmit impulses between the body-cells and the brain-cells, while red blood cells sculpted like poker chips and 3/10,000th of an inch in diameter, carry life giving oxygen around the body.

What is “self”? (2)

Nearly every substance known to mankind bears a chemical identity card made of a characteristic pattern of molecules at its surface.  Each of these cells that make up our own tissues and organs carries such an identity card.  Because the innate intelligence of the body uses genes to determine the shape and nature of these human selfmakers, they are unique to each individual.

Lodged in the outer surface of our cells, they stand as flags of our identity.

Amazing isn’t it?
