A medullary bone is a specialized bone tissue that acts as a calcium reservoir, found primarily in female birds and dinosaurs during their reproductive cycle.
Understanding Medullary Bone
Medullary bone is a unique skeletal element, playing a crucial role in avian and dinosaur physiology. Here’s a breakdown:
-
Definition: According to provided information, medullary bone is a layer of material found inside a regular bone in birds and dinosaurs.
-
Composition and Function: It is a porous and spongy layer of bone tissue rich in calcium. This calcium is essential for the formation of eggshells in female birds. Medullary bone is full of extra calcium.
-
Occurrence: This type of bone forms inside the bones of females when they are going to lay eggs.
Medullary Bone: Key Features
To summarise, here's a table highlighting the key characteristics of medullary bone:
| Feature | Description |
|---|---|
| Location | Inside regular bones |
| Composition | Porous, spongy, and rich in calcium |
| Function | Calcium reservoir for eggshell formation |
| Occurrence | Female birds and dinosaurs prior to egg-laying |
| Timing | Forms when females are preparing to lay eggs |
