System, cellular, organismal, chemical, tissue Cellular, chemical, organ, tissue, organismal Chemical, cellular, tissue, organ, system, organismal Tissue, cellular chemical, organismal, system Organismal, cellular, chemical, tissue, organ

Chemical, cellular, tissue, organ, system, organismal

stratified squamous epithelium

Consists of two or more layers of cells; cells in the apical layer and several layers deep to it are squamous; cells in the deeper layers vary from cuboidal to columnar.

In the figure shown, the carpals are ______ to the humerus? anterior posterior proximal distal superior

Distal

The sagittal plane is a vertical plane that divides the body into anterior and posterior segments. True False

False Sagittal plane is a vertical plane that divides the body or organ into right and left sides. A frontal (coronal) divides the body or an organ into front and back portions.

Medial

A system in the body is composed of related _______ with a common function.

Organs

The liver, heart, pancreas, and lungs would be good examples of ________. Systems Tissues Organs Chemicals Organ systems

Organs

Anatomy focuses on the __________________ of the human body. Function Biochemistry Structure Size

Structure

Cells with a common function form ________ which work together for a special role or function. Systems Tissues Organs Chemicals Organ systems

Tissues

which anatomical plane divides the body into top and bottom "halves"? Frontal Coronal Transverse Oblique Sagittal

Transverse

Pseudostratified columnar epithelium has one layer of cells. True False

True it gives the FALSE impression of a multilayered tissue—thus the name pseudostratified epithelium (pseudo-=false).

What is the difference between a plane and a section? a section is a cut whereas a plane is an imaginary flat surface that passes through the body a section is part of a plane with the section being a smaller part of the plane a section is a three-dimensional view of a plane a section and plane are actually the same thing

a section is a cut whereas a plane is an imaginary flat surface that passes through the body

Epithelial tissues play which important roles in the body? absorption filtration protection secretion all of these choices are important roles for Epithelial tissues

all of these choices are important roles for Epithelial tissues

The following terms/names - simple squamous; stratified cuboidal and simple columnar - reflect the ________ of epithelial cells. number of layers shape both number of layers and shape

both number of layers and shape

Epithelial tissues can be classified into various categories according to cell shape and number of layers type of fibers and number of layers presence or absence of blood vessels location in the body

cell shape and number of layers

Heart valves need to be able to resist stress in various directions. Which type of connective tissue best serves this purpose? dense regular reticular areolar dense irregular

dense irregular

Which tissue is characterized as having a free surface, being avascular (without blood vessels), and containing layers of cells? epithelial connective muscular nervous

epithelial

The major difference between ______________ tissue and _______________tissue is the percentage of cells to matrix. Use figure below as reference. muscle, connective epithelial, nervous epithelial, connective nervous, connective

epithelial, connective

Which of the following types of cells, found in connective tissue, are the most abundant? macrophages adipocytes mast cells fibroblasts white blood cells

fibroblasts

When the human body is in the anatomical position, the palm of the hand faces:

forward

Connective tissues differ from epithelia in that they have much extracellular material have tightly packed cells have no blood vessels have a free surface

have much extracellular material

Which of the following tissues has as a distinguishing characteristic, the ability to contract (shorten)? connective epithelial muscular nervous

muscular

In the figure shown, which type of epithelium is indicated? simple columnar epithelium simple cuboidal epithelium simple squamous epithelium stratified squamous epithelium transitional epithelium

simple columnar epithelium

Which type of epithelium consists of two or more layers of cells that protect underlying tissues in locations where considerable wear and tear occur? stratified epithelium simple epithelium pseudostratified epithelium two of the choices are correct

stratified epithelium doesn't include pseudostratified epithelium because it's actually a simple epithelium because all its cells rest on the basement membrane.

Which of the following is a typical characteristic of connective tissue? composed of cells closely joined together composed of cells that are able to conduct electrical impulses occur on body surfaces structure of extracellular matrix determines much of the tissue's qualities not supplied with nerve cells

structure of extracellular matrix determines much of the tissue's qualities
