Stratified columnar epithelium is the most common type of epithelium and is found in many areas throughout the body.

Question 21

The primary germ layers that are formed in the embryo are epithelial,connective,muscular,and nervous.

Question 22

Because connective tissue is avascular,food and oxygen must pass through the basement membrane to reach the blood vessels in the epithelial tissue.

Question 23

Skeletal muscle cells are referred to as muscle fibers and are characterized by a high degree of contractility.

Question 24

Cells in the embryo begin the process of cell differentiation.

Question 25

Epithelial tissue performs different functions based on the different types of matrix that make up the tissue.

Question 26

Osteoblasts are specialized cells that build bone tissue.

Question 27

Basic characteristics of the nervous system are excitation and conduction.

Question 28

The upper layer of stratified cuboidal epithelium can be keratinized for protection of the tissue below them.

Question 29

Connective tissue makes up the glycoprotein part of the basement membrane.

Question 30

Striated muscle tissue can be controlled both voluntarily and involuntarily.

Question 31

Hormones are released into ducts by exocrine glands.

Question 32

Epithelial tissue produces the glycoprotein part of the basement membrane.

Question 33

All the cells that make up tissues are held together by intracellular structures called desmosomes.

Question 34

Skeletal muscle tissue is striated and voluntary.

Question 35

In some tissues,the cells are held together by desmosomes and in other tissues they are held together by nonliving matrix.

Question 36

About 40% of the bone matrix is made of inorganic material.

Question 37

Adhesive molecules called integrins help bind epithelial cells to the basement membrane.

Question 38

Epithelial tissue can be classified by the number of layers the tissue has.

Question 39

When transitional epithelium stretches,the cell shape changes from cuboidal to squamous in appearance.

Question 40

Epithelial tissue can be classified by the shape of the cells.

Question 41

Tendons have more elastic fibers than do ligaments.

Question 42

Apocrine gland cells die as a result of their functioning.

Question 43

Both neurons and neuroglia are found in nervous tissue.

Question 44

Hyaluronidase assists in the absorption of injected drugs.

Question 45

Proteoglycans are composed of glucosamine bound to a polysaccharide core.

Question 46

Canaliculi allow osteocytes to stay alive within the bone tissue.

Question 47

Hormones are released into the blood by endocrine glands.

Question 48

When epithelial tissue is badly injured,a thick scar,or keloid,may develop.

Question 49

Because of the stripes visible under the microscope,smooth muscle is called striated muscle.

Question 50

Elastic fibers are made of the protein elastin.

Question 51

Osteoclasts are bone-destroying cells.

Question 52

Osteocytes were once osteoclasts that became trapped in the hardening bone tissue.

Question 53

The lack of blood vessels in cartilage tissue hinders its ability to heal.

Question 54

Connective tissue tends to have large quantities of extracellular matrix.

Question 55

Many of the sugars attached to the protein backbone of a proteoglycan molecule are fibronectin.

Question 56

Endocrine glands can be classified by the shape and complexity of their ducts.

Question 57

Both collagenous fibers and reticular fibers are made of collagen.

Question 58

Connective tissue can be classified based on the type of matrix it contains.

Question 59

The matrix for blood tissue is plasma.

Question 60

The most numerous type of cell found in areolar tissue is the macrophage.

Question 61

The serous membrane covering the lungs is the visceral pleura.

Question 62

In the process of endochondral ossification,the bone that is formed replaces cartilage.

Question 63

Connective tissue membranes are made up of two kinds of tissue.

Question 64

Epithelial tissue can be subdivided into two types: squamous and columnar.

Question 65

A group of cells that performs a common function is called tissue.

Question 66

Important functions of connective tissue include protection,secretion,and absorption.

Question 67

The concentric layers of bone matrix are called lacunae.

Question 68

Simple cuboidal epithelium is one cell layer thick; stratified cuboidal epithelium is more than one layer thick.

Question 69

A malignant tumor that arises from epithelial tissue is generally called a sarcoma.

Question 70

Astrocytes form the blood-brain barrier that helps protect the brain from harmful substances.

Question 71

An example of a cutaneous membrane is the skin.

Epithelial tissue is generally able to renew itself throughout life.

Question 73

Pseudostratified columnar epithelial tissue is only two layers thick.

Question 74

The type of tissue that lines the vagina,mouth,and esophagus is called keratinized squamous epithelium.

Question 75

Because stratified squamous epithelium is found in the urinary system,it is sometimes called urothelium.

Question 76

Oligodendrocytes help destroy damaged tissue and pathogens in the brain.

Question 77

A type of abnormal gene that seems to cause cancer is called an oncogene.

Question 78

The term squamous comes from the Latin word meaning scaly,which describes the flat,plate-like cells.
