Example Questions
Example Question #5 : Connective Tissue
Which of the following roles does connective tissue NOT fill?
Relay of electrical signals
Transport of important substances throughout the body
Support of internal organs
Protection of internal organs
Relay of electrical signals
Relay of electrical signals is performed by the nervous system, not by connective tissue.
Example Question #1 : Understanding Properties Of Connective Tissue
Which of the following is an example of the function of connective tissue?
Detecting changes in the environment
Covering body surfaces
Binding organs together
None of these answers
Contracting to generate force
Binding organs together
Connective tissue is responsible for binding organs together and is defined by a set of common cells suspended in an extracellular matrix. Blood, bone, adipose, and ligaments are all considered connective tissue.
Epithelial tissue covers body surfaces, nervous tissue detects changes in the environment, and muscular tissue generates force by contracting.
Example Question #2 : Understanding Properties Of Connective Tissue
Which of the following is not a function of connective tissue?
Supporting body organs
Protection of body organs
Binding organs together
All of these are functions of connective tissue
Energy storage
All of these are functions of connective tissue
Connective tissue has a wide variety of functions, including all of the given answer options. Along with epithelial tissue, connective tissue is one of the more versitile tissues in the body. Bone, cartilage, and fibrous connective tissue provide support and protection to organs. Loose connective tissue and fibrous connective tissue are common components of basement membranes and connective structures that bind organs together; ligaments and tendons perform similar functions for muscle and bone connections. Adipose tissue (fat) is used to store energy for long periods.
Example Question #3 : Understanding Properties Of Connective Tissue
Which of the following is true of connective tissue?
Cells are separated by a large amount of extracellular material
It does not contain any blood vessels
None of these
Cells are tightly packed together
It is responsible for producing many hormones
Cells are separated by a large amount of extracellular material
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 #4 : Understanding Properties Of Connective Tissue
Which of the following is a type of connective tissue cell?
Adipocyte
White blood cell
All of these
Plasma cell
Fibroblast
All of these
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 #5 : Understanding Properties Of Connective Tissue
Which of the following is not a type of blood cell?
Neutrophil
Leukocyte
Erythrocyte
Thrombocyte
Pinocyte
Pinocyte
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.
