Epithelium

Question 1

Epithelium

Answer 1

Lining of the body surface and cavities, aggregated cells with small amount of extracellular matrix.

Question 2

Connective Tissue

Answer 2

Several types of cells with abundant amount of extracellular matrix. It is present between other tissues and provide support and protection.

Question 3

Muscular Tissue

Answer 3

Elongated cells with moderate amount of extracellular matrix, allow movement.

Question 4

Nervous Tissue

Answer 4

Cells with elongated processes specialized for receiving, generating and transmitting nerve impulses.

Question 5

Mesenchymal cells

Answer 5

These cells serve as a reservoir of cells that can differentiate into any other type of connective tissue cells.

Question 6

Fibroblast cells:

Answer 6

Most common cells and responsible for the synthesis of fibers and intercellular ground substance (wound repair).

Question 7

Myofibroblast:

Answer 7

Fibroblasts that contain actin filament; play role in contraction during wound healing.

Question 9

Reticular cells:

Answer 9

Stellate-shaped cells, with spherical nucleus and basophilic cytoplasm - produce reticular fibers.

Question 10

Unilocular Adipocytes

Answer 10

filled with large lipid droplets and nucleus is displaced to the periphery.

Question 11

Multilocular adipocytes (brown fat)

Answer 11

have a centrally located nucleus with multiple lipid droplets and high concentration of the mitochondria in the cytoplasm.

Question 12

Pericytes

Answer 12

Pericytes are elongated cells that wrap around the endothelial cells lining small blood vessels. These cells contain actin and myosin to regulate the blood flow.

Question 13

Mast cells:

Answer 13

Common in loose CT and are abundant around blood vessels. These cells produce heparin (anticoagulant) and histamine (vasodilator to increase permeability).

Question 14

Plasma cells:

Answer 14

These cells are abundant in lymphatic tissues and produce antibodies.

Question 15

Macrophage:

Answer 15

Phagocytic cells found in connective tissue and contain numerous lysosomes.

Question 16

Pigment cells:

Answer 16

cells containing pigments (melanin), e.g., dermis, uterine caruncles, choroid, and iris.

Question 17

Leukocytes:

Answer 17

lymphocytes, monocytes, and granulocytes (blood cells) that migrate through the wall of the capillaries to the connective tissues.

Question 18

Collagen fibers

Answer 18

These are present in tendon, ligament, and organ capsules.

Question 19

Reticular Fibers

Answer 19

These fibers form the framework of liver, endocrine, lymphatic organs.
