Example Question #11 : Connective Tissue

Which of the following is true of connective tissue?

Possible Answers:

Cells are separated by a large amount of extracellular material

It is responsible for producing many hormones

Cells are tightly packed together

It does not contain any blood vessels

None of these 

Correct answer:

Cells are separated by a large amount of extracellular material

Explanation:

Connective tissue is mostly extracellular material, with cells scattered sparsely throughout. One of the main components of the extracellular material involved in most connective tissue is collagen, a fibrous protein that plays a structural role. 

Example Question #12 : Connective Tissue

Which of the following is a type of connective tissue cell?

Possible Answers:

Plasma cell

White blood cell

Fibroblast

Adipocyte

All of these

Correct answer:

All of these

Explanation:

Most connective tissue cells are fibroblasts (fiber-producing cells), which secrete the proteins that comprise the extracellular matrix. All blood cells are considered connective tissue, including white blood cells and plasma cells (mature B-lymphocytes). Adipocytes (fat cells) are responsible for connecting and surrounding body organs, and providing structural support, as well as storing energy for the body. 

Example Question #13 : Connective Tissue

Which of the following is not a type of blood cell?

Possible Answers:

Neutrophil

Pinocyte

Erythrocyte

Leukocyte 

Thrombocyte

Correct answer:

Pinocyte

Explanation:

Blood cells, also called hematocytes, fall into three general categories: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).  

Erythrocytes primarily carry oxygen and collect carbon dioxide through hemoglobin. Leukocytes are involved in the immune system, defending the body against infections and foreign materials. One type of leukocyte is a neutrophil. Thrombocytes are very small cell fragments that are involved in hemostasis (stopping bleeding) and the formation of blood clots.

Pinocytes do not exist. However there is a mechanism called pinocytosis by which cells ingest extracellular fluid and its contents.
