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.
