bones

Question 1

Central canal (in osteon)

Answer 1

holds a nerve, artery, and vein

Question 2

Canaliculus(in osteon)

Answer 2

Tiny canals that connect mini caves known as Lacuna

Question 3

Lacuna(in osteon)

Answer 3

house matured osteoblasts that become trapped by their bone matrix secretion and
mature into Osteocytes to maintain bone matrix

Question 4

Lamella(in osteon)

Answer 4

rings of bone tissue

Question 5

Bone tissue

Answer 5

Specialized connective tissue

Question 6

Bone matrix

Answer 6

secreted by osteoblasts
Maintained: by osteocytes
broken down by osteoclasts

Question 7

spongy bone

Answer 7

is found deep to the compact bone,
where there are medullary cavities for bone marrow

Question 8

why is their compact bone on the outside and spongy on the inside?

Answer 8

This organization of bone allows it strength to withstand weight distribution of body while
ensuring they are light enough to allow for efficient gross body movement.

Question 9

structural unit of bone:

Answer 9

osteon

Question 10

Irregular bones:

Answer 10

vertebre

Question 11

Sesamoid bones

Answer 11

almond shaped bones that form within tendons

Question 12

Sutural bones:

Answer 12

tiny bones between cranial bones

Question 13

Diaphysis

Answer 13

Shaft of long bone

Question 14

Periosteum

Answer 14

a fibrous membrane covering made up of dense irregular connective tissue

Question 15

Perforating fibers

Answer 15

collagen fibers of the periosteum that penetrate into the bone

Question 16

Epiphysis

Answer 16

The ends of the long bone

Question 17

Articular cartilage

Answer 17

covers the epiphysis in place of the periosteum. The glassy hyaline cartilage
provides a smooth surface to minimize friction at joints

Question 18

Epiphyseal lines:

Answer 18

Once the long bone has stopped growing, these epiphyseal plates are replaced
with bone and appear as thin, barely discernible remnants

Question 19

Yellow bone marrow:

Answer 19

adipose tissue found in medullary cavities

Question 20

Red bone marrow:

Answer 20

Blood forming tissue found in medullary cavities

Question 21

Endosteum

Answer 21

Delicate lining of shaft(medullary cavity)

Question 22

Axial skeleton

Answer 22

Cranium, Vertebral Column, Ribcage

Question 23

Appendicular Skeleton

Answer 23

Pectoral girdle, bones of the upper limb, pelvic girdle, Bones of the
lower limb.
