AnaphyLec Tissues

Which of these is NOT one of the four basic tissue types?

• Glandular

• Connective

• Muscle

• Epithelium

• Nervous

Understanding tissue structure and function is important because

• there is a relationship between the structure of each tissue type (how it is organized) and its function (what it does)

• there is a relationship between tissue structure and organ function.

• many diseases and pathologies are tissue and cell type specific.

• changes at the tissue level affect the function of organs.

• All of the choices are correct.

Which of the following is NOT a true statement about epithelial tissue?

• Epithelial tissue is vascular.

• Epithelial tissue provides physical protection for organs.

• Epithelial tissue functions in absorption and secretion.

• Epithelial tissue controls the permeability into and out of an area or organ.

• Epithelial tissue consists almost entirely of cells, with very little extracellular material between them, thereby forming a barrier against entry into the body.

Epithelial cells

• cover body surfaces or form glands.

• usually have a free surface that is not in contact with other cells.

• have a basement membrane that attaches to underlying tissues.

• can be somewhat far away from any blood vessel.

• All of the choices are correct.

When you get sunburn after a day at the beach, which of the following membranes have you damaged?

• Serous

• Cutaneous

• Peritoneal

• Synovial

• Pleural

The most correct classification of an epithelial tissue consisting of many layers of cells, in which the outer layers are flat and thin and the basal layers are cuboidal or columnar, is

• simple columnar epithelium.

• pseudostratified epithelium.

• stratified squamous epithelium.

• transitional epithelium.

• simple squamous epithelium.

Epithelial cells that appear cube-like when an organ is relaxed, and flattened when the organ is distended by fluid, are classified as

• simple columnar epithelium.

• pseudostratified epithelium.

• stratified squamous epithelium.

• transitional epithelium.

• simple squamous epithelium.

Connective tissue

• joins together cells and tissues and transports substances.

• provides a supporting framework for the body.

• is characterized by large amounts of extracellular matrix.

• Both "joins together cells and tissues and transports substances" and "is characterized by large amounts of extracellular matrix

• All of the choices are correct.

Which kind of connective tissue cells is NOT correctly matched with its function?

• -blast cells—make holes in extracellular matrix.

• -clast cells—break down the extracellular matrix.

• -cyte cells—maintain the extracellular matrix.

• Mast cells—release chemicals promoting inflammation.

• Macrophages—move about and ingest foreign substances.

Which of these is NOT a characteristic of cardiac muscle?

• Striated

• Branching fibers

• Intercalated disks present.

• Under involuntary (unconscious) control

• Many nuclei per cell
