Growing Bones

Ossification and Growing Bones

QuestionAnswer
The process of bone formation is called WHAT? Ossification
Ossification takes place during the late embryonic period with the formation of fibrous connective tissue and BLANK cartilage. Hyaline cartilage
Bone forming cells are called WHAT? Osteoblasts
These bone forming cells secrete calcium and other minerals to form bone. Osteoblasts
Most bones are formed by endochondral ossification as bone tissue replaces WHAT? Cartilage
Longitudinal growth takes place at what part of the bone? Epiphyseal disc (band of hyaline cartilage at proximal/distal ends of bone)
These are the proximal and distal ends of the bone where there is a band of hyaline cartilage where longitudinal growth takes place is called WHAT? Epiphyseal disc
Cartilage is invaded by WHAT and becomes ossified. Osteoblasts
Osteoblasts are WHAT? Bone cells
Cartilage that is invaded by Osteoblasts and becomes ossified and matures into bone called WHAT? Osteocytes (bone)
Longitudinal growth is affected by what 2 things? Growth hormones and sex hormones (estrogen/testosterone)
These cells break down bone tissue and hollow out bone on the inner bone surface like sculpting. They are called? Osteoclasts
The process whereby Osteoclasts (cells) break down bone (matrix) tissue is called bone WHAT? Resorbtion
These cells are continuously depositing bone on the external bone surface (the undersurface of the periosteum). Osteoblasts
There are 2 types of ossification. What are they? Intramembranous (tissue membrane with bone - skull) Endochondral ossification (replacement fetal cartilage skeleton with bone)
In this type of ossification, the thin connective tissue membrane in the skull is replaced with flat bones. Intramembranous ossification
In this type of ossification, the fetal cartilage skeleton is replaced with bone. Endochondral ossification

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
