What does skeleton mean?

Dried up

1

What is osteology?

The study of bones

2

What are the extra bones in the sutures of the skull called?

Sutual bones or wormian bones

3

Bones that develop in tendons in response to stress as the tendons repeatedly move across a joint are called what?

Sesamoid bones

4

Where does everyone have a Sesamoid bone?

At the anterior surface of the kneecap or patellae

5

What is a semi-rigid connective tissue that is weaker than bone, but more flexible and resilient.

Cartilage

6

What is a chondroblast?

An immature cartilage producing cell. Matures into a chondrocyte

7

What does a chondrocyte do?

Maintains the matrix of the cartilage and ensures that it remains healthy and viable

8

What does avascular mean?

Not penetrated by blood vessels

9

Why doesn't cartilage heal well?

Its avascular so there isn't a blood supply to it

10

Major functions of cartilage

Supporting soft tissue, provides a gliding surface at articulations, provides a model for the formation of most bones in the body

11

What are the types of cartilage?

Hyaline cartilage, fibrocartilage, elastic cartilage

12

What is the most abundant cartilage type?

Hyaline cartilage

13

What cartilage is found in the nose, trachea, portions of the larynx, the articular cartilage on bones, Growth in growing bones, and the fetal skeleton?

Hyaline cartliage

14

Where it's Hyaline cartilage found?

In the nose, trachea, portions of the larynx, the articular cartilage on bones, growth plates in growing bones, and the fetal skeleton.

15

Which cartilage supplies support and flexibility and resilience, and it's extracellular matrix has a translucent appearance?

Hyaline cartilage

16

What does Hyaline mean?

Translucent appearance

17

What cartilage has an extracellular matrix with numerous thick collagen fibers that help resist both stretching and compression?

Fibrocartilage

18

Where is fibrocartilage found?

Between the vertebrae and where the pubic bones join at the pubic symphysis

19

What cartilage is between the vertebrae and where the pubic bones join at the pubic symphysis

Fibrocartilage

20

Which cartilage contains highly branched elastic fibers within its avascular extracellular matrix?

Elastic cartilage.

21

Where is elastic cartilage found?

The external ear, the ear canal, the epiglottis that guards the entrance to the larynx

22

What are the tissue types of bones?

Vascular, nervous, connective, muscular, cartilage, and osseous

23

What is calcification

A process of making bones sturdy and rigid because of deposits of in minerals in the matrix

24

What are the functions of bones?

Support and protection, movement, hemopoisis/hematopoiesis, and storage of mineral and energy reserves

25

What is hemopoiesis?

The process of blood cell formation

26

What is hematopoiesis?

The process of blood cell formation

27

What bones in adults have active red marrow?

Flat bones of the skull, vertebrae, ribs, sternum, bones of the pelvis (ossa coxae), proximal ends of the long bones

28

What happens to inactive red marrow in adults?

It turns into fatty tissue called yellow bone barrow
