Question 1

What are the functions of bones

Answer 1

-Supports and protects organs, cranial cavity, and thoracic cavity

Question 2

yellow bone marrow

Answer 2

stores lipids

Question 3

How are bones classified

Answer 3

shape
-Long bones, short bones, flat bones, and irregular bones

Question 4

Long Bones

Answer 4

• greater in length than width
  -distribute stress on bone from weight by being slightly curved
  -located in legs, arms, toes, forearm, and fingers

Question 5

Short Bones

Answer 5

-have lengths and widths that are roughly equal
-usually cube- like
-located in wrist and ankle

Question 6

Flat Bones

Answer 6

-plate- like structures, thin
-usually areas for muscle attachment
-located in cranium, sternum, ribs, and shoulder blade

Question 7

Irregular Bones

Answer 7

-variety of shapes
-usually are connected to other bones
-located in vertebrae, and facial bones

Question 8

what do bones and limbs help support

Answer 8

weight

Question 9

bone remodeling

Answer 9

breaking down and remodeling of bones

Question 10

formation of blood cells=

Answer 10

red, white, and platelets
-called hemoglobin

Question 11

what does yellow done marrow store

Answer 11

lipids

Question 12

sesamoid bones

Answer 12

-small bones that are embedded with tendons next to joints
-located at patella, 4 in your hand, and 2 in foot

Question 13

diaphysis

Answer 13

shaft or long main portion of bone
-lies between the epiphyses

Question 14

epiphysis

Answer 14

distal and proximal ends of bone
-forms joints with other bones
-covered in hyaline cartilage

Question 15

what does articular cartilage cover

Answer 15

covers the epiphyses

Question 16

articular cartilage

Answer 16

-where bone forms an articulation or joint
-reduces friction and absorbs shock

Question 17

periosteum

Answer 17

-membrane around the surface of the bone that is NOT covered by articular cartilage
-vascular, fibrous tissue
-helps in forming bone tissues ans repair

Question 18

medullary cavity

Answer 18

-rigid tube with a hollow chamber
-space within the diaphysis filled with marrow
-it is red and yellow

Question 19

which cavity is filled with bone marrow

Answer 19

medullary cavity

Question 20

endosteum

Answer 20

-thin membrane surrounding medullary cavity
-contains bone-forming cells
-muscle contractions and action potentials

Question 21

(Mneumonic device)
Diaphysis
Epiphysis
Articular cartilage
Periosteum
Medullary cavity
endosteum
(you can change if you have better)

Answer 21

-D get it shaft yuh long hehe lies between e brake bc we no like men
-E looks like locked arms with someone joints
-Pe like pediatriction repairs bone and tissue doctor
-M marrow
-End of our bone forming process

Question 22

How are bones classified

Answer 22

According to their SHAPE

Question 23

Why are long bones slightly curved

Answer 23

to distribute stress on bone from weight

Question 24

what 2 types of bone tissue is bone made of

Answer 24

compact and spongy bone

Question 25

osteoprogenitor cells

Answer 25

-unspecialized cells that make bone cells
-CAN undergo Mitosis
-develop into osteoblasts or osteoclasts
-located in periosteum, endosteum, and canals containing blood vessels `

Question 26

osteoblasts

Answer 26

-cells that form bone tissue (=deposition)
-cannot undergo mitosis
-secrete collagen and other components to help build bone
-located in surfaces of bones

Question 27

osteocytes

Answer 27

-mature bone cells
-form from osteoblasts
-cannot undergo mitosis
-no longer secrete matrix material
-carry out nutrient exchange and waste removal with blood
-location= buried within solidified bone matrix

Question 28

osteoclasts

Answer 28

-complete bone resorption (destruction of matrix)
-important in growth maintenance and repair of bone
-located in bone surfaces
