Platelets (thrombocytes) are not cells, they are just pieces of the megakaryocytes (their mighty parents).
Platelets are called thrombocytes because they will help form a clot (thrombus)...At least they form a temporary platelet plug to stop bleeding in small vessels (primary hemostasis).
The normal platelet count is 150,000 to 400,000/ microliter.
Get all of my notes at / medicosis
Hemostasis is defined as "cessation of blood bleeding”
There are 2 types of hemostasis:
1. Primary hemostasis: formation of weak, temporary platelet plug (by platelets)
2. Secondary hemostasis: formation of stronger fibrin meshwork (by coagulation factors).

Platelet counts between 400 and 650 are significant! I was referred to a hematologist for an unexplained platelet counts of 500 to 630 over a few years. I now have a diagnosis of Essential Thrombocythemia with JAK2 mutation

[@doriskuen2874]

My platelet count is after 2 years finally in a normal range according to my hematologist. Was at 25 and now at 309 however my monocyte number has been at a high number of 29 area ever since thrombocytopenia diagnosis. What do monocytes have to do with?
So I supposedly have monocytosis and hematologist can’t explain.
Can you or anyone explain the significance or seriousness if at all ,of that?

[@sandral5087]

A decrease of the platelet count causing increase TPO is positive feedback, not negative feedback. You are an excellent teacher and I like your way of teaching. Keep going. Great job.

[@MedicosisPerfectionalis]

It’s a negative feedback, not a positive feedback!
Positive feedback would go like this: during labor, the descent of the fetal head will stretch the cervix, which will increase oxytocin, which contracts the uterine wall which increase the descent of the fetal head, which stretches the cervix,....and again, and again...etc!
You an read the first chapters of Guyton’s physiology to learn more!
Hope it helps!

Please help this question
Why the color of platelets is yellowish

[@christophermaddish5540]

Coined a new term-"Cytobudding." A special type of cell division that is NOT mitosis, NOT meiosis, and NOT binary fission. Here is the pitch: Platelets are created by a special king of cell division called "CYTOBUDDING," which is always a terminal division.
Why are platelets not cells? They have the suffix "-cyte" after all. They have an outer cellular membrane, they are metabolically active (make proteins), and even have mitochondria. So they don't divide and represent a terminal form, mature red blood cells don't divide and have no nucleus either, but they are allowed to be called cells?
Looks like cell, acts like a cell, but not a cell? What the H*||? Just because they are "born differently" they are kicked out of the Cell Club? I have even heard of platelets killing bacteria and are able to moving on their own will. But.if..you....can......expand.............your.....................mind.............................................to recognize the process of Cytobudding as specialized form of cell division, then just maybe, we can let the little guy into the club?
