A Receptor in the Negative Feedback System for Ca2+ Homeostasis within the body

A disease that comes from an insufficient calcium level in the body, making bones thinner and more susceptible to fracture

PTH stands for what

Of these 4, Which does not play a role in Homeostasis: A.Thyroxine B.Calcitonin C.Parathyriod Hormone D.Vitamin D

7- Dehydrocholesterol is the precursor molecule found in what

True or False: The Negative Feedback System is rare in the body

A disease caused by a vitamin D deficiency in childhood, which results in low blood calcium levels, and bowing lower limb long bones

The number of Parathyroid Glands that are located on the Thyroid Gland

True or False: The Nervous System is affected when calcium levels are too high or too low

The precursor molecule 7-Dehydrocholesterol converts to what in Calcium Homeostasis

An organisms ability to maintain a consistent internal environment

This molecule is a necessary element of blood plasma, Important in muscle and nerve function, plays an important factor in blood clotting

When levels of Calcium are down, PTH activates what in the bones that breakdown Calcium and allows for reabsorption in the bloodstream

The primary place in the body for calcium storage

The organ that synthesizes calcidiol from Vitamin D

The most common body structures that act as Effectors

Having low amounts of Calcium in the bloodstream is a condition known as

In the Parathyroid Gland, when levels of Calcium in the blood stream are down, It will release more PTH through what process

The main way calcium gets into the body

The kidneys convert calcidiol to this

The type of response the Endocrine System gives

A condition that begins, as you lose bone mass and your bones become frail. This happens when the inside of your bones become brittle from a loss of calcium.

The Parathyroid Gland is located here

The three hormones involved in calcium homeostasis

A main dietary source that humans can obtain Vitamin D from
