3. A hallmark syndrome of achondroplasia is what? (hint: _______ finger)

AHHHHHHH I'LL ANSWER THIS SOON

i was going to sooner but school happened

but i promise i will!

3. A hallmark syndrome of achondroplasia is what? (hint: _______ finger)

1. I assume you mean sensory receptors my anatomy game has been declining slightly need to practice more O-O
Meissner corpuscles-light vibrations, changes in vibration
End bulbs of Krause-Cold temperatures
Ruffini endings-stretching
Pacinan corpuscles-deep pressure and vibrations
Merkel Discs-sustained touch/pressure

2. Tetanospasmin is the nuerotoxin of tetanus, and causes muscles spasms, rigidity, and lockjaw, one of the main symptoms of tetanus.

3. I was gonna say short stature, but the hint was finger, so I'll go with small fingers.
finally finished my homework

alrighty also the astronomy thread is trying to beat us and succeeding, so let mess up their goal >:)

here are some fun diseases and histology!

1. What disease is shown in the image below? are males affected more than females? Are patients with this disease symptomatic?


2. What type of tissue is shown below? In what layer of the skin is it found in?


3. Name the type of diseases each condition is below (viral, bacterial, autoimmune, etc.)
Poliomyelitis
Tetanus
Myasthenia Gravis
Muscular Dystrophy

2. Areolar Connective Tissue, Hypodermis
3. Viral, Bacterial, Autoimmune,(irdk what to say here) Genetic/Inherited?[

All good! Your turn!

Alright, guess I'll ask a few questions.
1.What are osteoprogenitor cells?
2.what is osteocytogenesis? And name some important molecules in the process
3.10%-20% of osteoblasts differentiate into osteocytes. True or false?
4.What are the steps of mesenchymal stem cell differentiation to form specialized mature cells? (what cells do they become in the process)
They're all skeletal, but I hope they help out :o)

yesss skeletal time >:D
1, Osteoprogenitor cells, also known as osteogenic cells, are the stem cells of the bone that give rise to more specialized bone cells
2. Osteogenesis is the formation of osteocytes in the bone. Some important molecules include matrix metalloproteinases and oxygen (i think)
3. True
4. I believe they start from perivascular progenitior cells, become mesenchymal stem cells, and then differentiate into osteoblasts.

hehe skeletal system best system >:D
1.yoo you're righ!! 2.yes that's very true 3.yes 4.this is what I have- mesenchymal stem cell-> osteoprogenitor-> pre-osteoblast->osteoblast-> pre-osteocyte->mature osteocyte. I'm not sure about the role of perivascular progenitor cells in forming specialized mature cells. If you know could you pls tell me? I only know about stem cells in boens not progenitor ones in depth hehe i love boens
