Which branch of anatomy focuses on the study of all structures in a single body region?

All of the cavities contain serous fluid.

surface anatomy

C. the study of shapes and markings on the body surface that reveal underlying organs

Which of the following terms indicates the neck region?

Cervical

Which type of cell junction is also referred to as an anchoring junction?

Desmosomes are called anchoring junctions because proteins extending from adjacent cell membranes link adjoining cells. These junctions allow for movement and greater spacing between adjacent cells.

The mediastinum contains the following viscera:

ESOPHAGUS HEART TRACHEA

Which statement below is NOT a characteristic of epithelia? -Epithelia have a "free" apical region and a basal region adjacent to underlying connective tissue. -Epithelia contain many cells closely packed together with little extracellular material. -Epithelia is innervated; it contains nerve endings. -Epithelia are highly vascularized.

Epithelia are NOT vascularized. All epithelia receive oxygen and nutrients, and get rid of cellular wastes via diffusion with the underlying highly vascularized connective tissue.

The inguinal regions are medial to the umbilical region.

False

The orbits in the skull house the eyes and present them in a posterior position.

False

What is the advantage of functional magnetic resonance imaging (fMRI) over positron emission tomography (PET)?

Functional MRI pinpoints smaller brain areas, does not use radioactive tracers, and works faster.

The axillary region is _____ to the sternum.

LATERAL

The right upper quadrant contains all or portions of which of the following organs?

Liver, stomach, and transverse colon

Which of the following statements describing cilia is false? -Cilia contain microtubules. -At the base of each cilium is a centriole, called a basal body. -Cilia produce a propulsive thrust to create the one-way flow of fluid over an epithelial surface. -Cilia increase the apical surface area of an epithelial tissue to maximize transport across the surface membrane.

Microvilli, not cilia, are extensions of the plasma membrane that increase the apical surface area.

The __________ cavity surrounds many visceral organs in the abdominopelvic cavity.

Peritoneal

The plasma membrane is composed of all of the following

Phospholipids ,cholesterol, glycoproteins

Which of the following statements is correct about scanning electron microscopy (SEM)?

SEM provides three-dimensional pictures of whole, unsectioned surfaces.

Which is false concerning the anatomical position?

The person is standing erect, with the head facing caudally.

The lateral surfaces of epithelial cells are characterized by _____.

Tight junctions, desmosomes, and gap junctions join the lateral surfaces of adjacent epithelial cells.

The macromolecules—such as carbohydrates, lipids, proteins, and nucleic acids—are the building blocks of cells, which are the smallest living units in the body.

True

Someone studying anatomy by the regional approach could study __________.

all the muscles, nerves, and blood vessels of individual areas of the body.

The __________ region of the body consists of the limbs or "extremities."

The scapular, vertebral, lumbar, and sacral regions are all part of the __________.

back

All vertebrates share certain identifying characteristics, at least during some point of development. A partial listing of these characteristics is __________.

The appendicular region ______.

consists of the arms, legs, feet, and hands

The right ear and left eye are __________.

contralateral

Which of the following pairs consists of anatomical opposites?

cranial, caudal

Parietal peritoneum covers the ______.

deep surface of the wall of the abdominal cavity

What imaging technique provides an unobstructed view of small arteries?

The olecranal region is ______ to the acromial region.

distal

An example of a tissue in the body is

The elaborate steps of preparing human or animal tissue for microscopy are __________.

fixation, sectioning, staining

Which of the following is not a basic feature that distinguishes all vertebrates at some point in their development?

four-chambered heart

The thumb is __________ to the index finger.

lateral

Which set of orientation and directional terms is not a pair of anatomical opposites?

lateral

The descending colon is located in which abdominal quadrants?

left upper and lower quadrants

Visceral peritoneum covers the __________.

liver

The right upper quadrant contains all or part of the __________.

liver, stomach, and gallbladder

________ are membranous sacs containing acid hydrolases and are sites of intracellular digestion.

lysosomes

Large molecules such as proteins are called

macromolecules

The sternal region is ______ to the axillary region.

medial

The dorsal hollow nerve cord runs along the back of vertebrate embryos in the __________ plane.

median

Embryonic pharyngeal pouches give rise to which of the following structures in humans?

middle ear cavity

The median plane is the same as the __________.

midsagittal plane.

The levels of structural organization in order of decreasing complexity are ______.

organism, organ system, organ, tissue, cellular, chemical

The word ________ always refers to the part of the serosa that lines a body cavity.

parietal

The uterus is located in which body cavity?

pelvic cavity

Which advanced imaging technique uses sound waves to construct a sectional image of the outlines of organs or other internal structures?

positron emission tomography (PET)

Which imaging technique is often used to diagnose cancer?

positron emission tomography (PET)
