Question 1

Where in the adult body does reticular connective tissue still predominate?&#10;A) Soft palate&#10;B) Tendons and bone&#10;C) Lymph nodes&#10;D) Dermis

Accepted Answer

Reticular connective tissue still predominates in the lymph nodes and spleen of the adult.Collagen fibers (Type I) are found in dermis,bone,tendons,and virtually all other types of connective tissue.Certain regions in the oral cavity,such as the soft palate,contain elastic fibers in the connective tissue of lamina propria.

Question 2

What is the term used to describe the amount of time it takes for newly divided cells to be completely replaced throughout a tissue?&#10;A) Fusion&#10;B) Mitosis&#10;C) Turnover&#10;D) Meiosis

Accepted Answer

The turnover time is the time it takes for the newly divided cells to be completely replaced throughout the tissue.The turnover time differs for each of the basic tissue types in the orofacial region,as well as for specific regions of the oral cavity.Fusion occurs during prenatal development when processes join together.Mitosis or cell division is the process,in the cell cycle,by which a cell duplicates into two genetically identical daughter cells.Meiosis is a special type of cell division necessary for sexual reproduction.

Question 3

The main superficial layer of the basement membrane is the _____ and is produced by the epithelium.&#10;A) reticular lamina&#10;B) basal lamina&#10;C) lamina lucida&#10;D) lamina densa

Accepted Answer

The main superficial layer of the basement membrane is the basal lamina and is produced by the epithelium.The deeper layer of the basement membrane is usually the reticular lamina produced by the underlying connective tissue.The lamina lucida is a clear layer that is closer to the epithelium,and the lamina densa is a dense layer that is closer to the connective tissue.

Question 4

The macrophages found in the connective tissue are derived from:&#10;A) neutrophils.&#10;B) monocytes.&#10;C) basophils.&#10;D) mast cells.

Accepted Answer

Within the connective tissue proper is the macrophage,which is considered a monocyte before it migrates from the blood into the tissue.The polymorphonuclear leukocytes or neutrophils are the first white blood cells to appear at an injury site when the inflammatory response is triggered.The basophil is a white blood cell in the blood involved in the hypersensitivity response,along with the mast cell in the connective tissue.

Question 5

Which type of blood cell is directly responsible for immunoglobulin production?&#10;A) Neutrophils&#10;B) Basophils&#10;C) Plasma cells&#10;D) Mast cells

Accepted Answer

The B-cell lymphocytes are white blood cells that divide during the immune response to form plasma cells.Once mature,plasma cells produce an immunoglobulin.The polymorphonuclear leukocytes or neutrophils are the first white blood cells to appear at an injury site when the inflammatory response is triggered.The basophil is a white blood cell in the blood involved in the hypersensitivity response,along with the mast cell in the connective tissue.

Question 6

What is the special term used for the simple squamous epithelium that lines the vessels and serious cavities of the body?&#10;A) Endothelium&#10;B) Reticular&#10;C) Pseudostratified columnar&#10;D) Epidermis

Accepted Answer

Simple squamous epithelium consists of flattened platelike epithelial cells,or squames,lining blood and lymphatic vessels,heart,and serous cavities,as well as interfaces in the lungs and kidneys.The term endothelium is used to refer to the simple squamous epithelium lining of these vessels and serous cavities.Epithelium can also be considered pseudostratified columnar epithelium because all the cells line up to contact inner the basement membrane even if all the cells do not reach the outer surface of the tissue.Epidermis is the superficial layer of the skin.The reticular fibers of connective tissue can be found in relationship to an evolving embryonic tissue.

Question 7

Which type of bone tissue has a Haversian system with osteons?&#10;A) Cancellous bone&#10;B) Compact bone&#10;C) Osteoid&#10;D) Immature bone

Accepted Answer

Deep to the periosteum is a dense layer of compact bone.Deep to the compact bone is a spongy bone,or cancellous bone.Both compact bone and cancellous bone have the same cellular components,but each has a different arrangement of those components.The highly organized arrangement of concentric lamellae in compact bone is the Haversian system.In the Haversian system,these lamellae form concentric layers of matrix into cylinders or osteons.Bone matrix is initially formed as osteoid,which later undergoes mineralization.The first bone to be produced is considered primary or immature bone.

Question 8

Which of the following tissue types provides nutrition for the underlying compact bone?&#10;A) Cartilage&#10;B) Periosteum&#10;C) Compact bone&#10;D) Cancellous bone

Accepted Answer

Periosteum is a double-layered,dense connective tissue sheath that covers the outer part of bone and provides nutrition for the underlying compact bone.Cartilage is present at articular surfaces of most freely movable joints,such as the temporomandibular joint.Deep to the periosteum is a dense layer of compact bone.Deep to the compact bone is a spongy bone,or cancellous bone.

Question 9

Which of the following basic tissue types is usually composed of fewer cells spaced farther apart and containing larger amounts of matrix between the cells?&#10;A) Epithelium&#10;B) Nerve tissue&#10;C) Muscle tissue&#10;D) Connective tissue

Accepted Answer

Connective tissue is composed of fewer cells spaced farther apart and containing larger amounts of matrix between the cells.Epithelium generally consists of closely grouped polyhedral cells surrounded by little or no intercellular substance or tissue fluid.A neuron is the functional cellular component of the nervous system.Each muscle is composed of numerous muscle bundles,or fascicles.

Question 10

The extensions of epithelium into connective tissue,as appear on histologic section,are the:&#10;A) connective tissue papillae.&#10;B) squames.&#10;C) basement membrane.&#10;D) rete ridges.

Accepted Answer

Interdigitation of the outer epithelium with the deeper connective tissue occurs with the epithelial tissue forming rete ridges,but there is always a basement membrane located between these two tissue types.Flattened platelike epithelial cells are called squames.
