Bone, Tissue, and Cartilage

Question 1

What are the Three Types of Muscles?

Answer 1

1) Skeletal
2) Cardiac
3) Smooth

Question 2

Skeletal Muscle

Answer 2

Is responsible for the movement of the skeleton and organs (capable of voluntary/conscious control). Histologically appears as striped, multi-nucleated, and have muscle fibers that are long cylinders

Question 3

Smooth Muscle

Answer 3

Muscle tissue in which the contractile fibrils are not highly ordered (involuntary control). Histologically appears as having no striations and each fiber is spindle shaped with one nucleus

Question 4

Cardiac Muscle

Answer 4

Provides for the continuous, rhythmic, contractibility of the heart (involuntary control). Histologically appears as branched and striated, with each muscle fiber having one nucleus and their ends have intercalated discs

Question 5

Cartilage

Answer 5

A semi-rigid form of supporting tissue

Question 6

Chondroblasts

Answer 6

A cell that produces cartilage

Question 7

Chondrocytes

Answer 7

A cell which has secreted the matrix of cartillage and become embedded in it; maintains the integrity of the cartilage

Question 8

What are the Three Types of Cartilage?

Answer 8

1) Hyaline
2) Elastic
3) Fibrous

Question 9

Hyaline Cartilage

Answer 9

Provides firm support with some pliability and holds the surrounding structures in place

Question 10

Fibrous Cartilage

Answer 10

Resists compression, prevents bone to contact and limits relative movement

Question 11

Elastic Cartilage

Answer 11

Cartilage with abundant elastic fibers; provides elastic flexibility

Question 12

Osteoid

Answer 12

Unmineralized bone matrix (resembles bone)

Question 13

Osteocytes

Answer 13

A bone cell, formed when an osteoblast becomes embedded in the matrix it has secreted

Question 14

Osteoclasts

Answer 14

Bone-destroying cells

Question 15

Osteoblasts

Answer 15

Bone-building cells

Question 16

Compact Bone

Answer 16

Hard, dense bone tissue that is beneath the outer membrane of a bone

Question 17

Cancellous Bone

Answer 17

Spongy Bone

Question 18

Haversian System

Answer 18

Concentric rings of interconnecting osteocytes surrounding a Haversian canal

Question 19

Haversian Canal

Answer 19

Passageways that run longitundinally in blood vessels to supply oxygen and nutrients to osteocytes within the Haversian system

Question 20

Endochondral Ossification

Answer 20

The formation of a continuously growing cartilage model which is progressively replaced by bone

Question 21

Ossification Center

Answer 21

Where bone formation begins
