Chart 4-6. The give and take. PTH also holds calcium in the kidney and asks the gut, with vitamin D.CGI copy of her Draw · Atlas keeps the original.

Usually four parathyroid glands on the back of the thyroid. When serum calcium is low they release PTH: osteoclasts resorb, calcium comes into blood, the kidney is asked not to spill it, the small intestine is asked to absorb it — that last wants vitamin D. When serum calcium is high, C cells of the thyroid release calcitonin and the arrow on her board turns the other way.

What the board got right, and what it simplified

The diagram is a fair teaching arrow: calcitonin in, PTH out. PTH does not personally sprinkle enzymes on a clast; it speaks to osteoblasts and lining cells, RANKL recruits the clast. Keep the arrow. Name the extra step if a student asks. Glucocorticoids in excess can push PTH and slow proline — Course 02 already taught steroids as a class that can thin tissue.

Influence on this door

Calcitonin, on her board, is increased with progesterone, confused by fluoride, and wants proline at the end of the molecule. Those three stand as emotional influence of the material. Vitamin D is asked on the same door as the gut’s absorption arrow — not as a fourth of those three. You ask.

Practice

Trace the two arrows on 4-6 with a finger: into bone, out of bone. Ask fluoride, vitamin D, progesterone, calcium as influence.

Check

Parathyroid hormone’s teaching job on this board is to:

  1. Take calcium out of bone when the blood is low — and ask kidney and gut to help ✓
  2. Put calcium into bone when the blood is full — that arrow is calcitonin
  3. Unlock the knee, with popliteus, because GB oversees bone

Out of bone, hold in kidney, absorb in gut. Calcitonin is the other arrow. Popliteus waits on Course 05.

You use the arrows by:

  1. Naming PTH out and calcitonin in, then asking fluoride, vitamin D, progesterone, calcium as influence ✓
  2. Parking PTH on kidney with psoas, because both say kidney
  3. Parking calcitonin on gallbladder so C cells share the tendon door

Two arrows, then influence. Kidney as organ on the chart is not iliopsoas as translator. GB is tendon-and-bone as address, not a C cell.

PTH and slow proline on this hour:

  1. Proof of supernatural status
  2. Course 02 already taught steroids as a class that can thin tissue ✓
  3. A dose you write from a yield

PTH and slow proline — Course 02 already taught steroids as a class that can thin tissue

This hour teaches that:

In and out of bone — keep this:

  1. A bottle that finishes the feeling
  2. PTH also holds calcium in the kidney and asks the gut, with vitamin D. ✓
  3. A tourist empty-mind contest

PTH also holds calcium in the kidney and asks the gut, with vitamin D.

Practice on this hour is to:

  1. Collapsing two houses into one word
  2. Trace the two arrows on 4-6 with a finger: into bone, out of bone. ✓
  3. Prescribe so the quiet looks finished

Method before bottle. Trace what the lesson names.

Chart 4-5 on this hour is used as:

  1. Squeezing the gate until it 'opens'
  2. Four small glands. PTH out. Calcitonin as antagonist. Fluoride and progesterone stand… ✓
  3. Opening a chakra by squeezing it

Translator map — Chart 4-5. Not a prescription pad.

The lab on this hour is for:

  1. A graded exam that invents the next curriculum
  2. Feeling and naming what the lesson maps — journal, not a bottle ✓
  3. A prescription pad for the lab name

Lab is literacy. Not a dose from the yield.

"In and out of bone" here is best treated as:

  1. A tourist collection of special experiences
  2. Usually four parathyroid glands on the back of the thyroid. ✓
  3. A rigid diagnosis tool that replaces sleep

Train with the map. Do not invent a second sky.
