Practice Quiz Q’s For Chapter 4 Flashcards
A group of cells that have a common origin and function together to perform a specialized group of activities is called a(n)_______
Tissue
This tissue covers body surfaces and lines hollow organs of the body such as the stomach and bladder
epithelial tissue
This type of tissue can function as fat storage, pad out and bind an organ together, wrap skeletal muscles, or transport substances
connective tissue
Of the four basic tissue types, which one can generate electrical signals that can trigger muscles contractions or glandular secretions?
Nervous tissue
Which type of cell junction would you expect to find anchoring the cells of the epidermis to each other. This type of junction gives the skin its ability to endure stretching and other mechanical stresses without tearing
Desmosomes
This type of junction contains tiny fluid-filled tunnels called connexons which allow the movement of ions and small molecules between cells. It is found between muscles cells of the heart and in organs with smooth muscle tissue such as the gastrointestinal tract
Gap junctions
If you wanted to design a tissue that restricted the movement of water and other molecules between adjacent cells, which type of junction would you use to connect the cells?
Tight junctions
In this type of cell junction, the transmembrane proteins are integrins which anchor the cell to a basement membrane
hemidesmosomes
This tissue has an extensive extracellular matrix, usually has many blood vessels, and provides oxygen and nutrients to overlying tissues
Connective tissues
Which tissue, depending on its location, and functions, is sometimes called endothelia or mesothelia?
simple squamous epithelium
Which type of tissue is found in the tubules of kidneys, the covering of the ovaries, and also in glandular tissues such as the thyroid gland? Its function is absorption and secretion
simple cuboidal epithelium
This type of epithelium has elastic properties. It can stretch and return to a less stretched condition. When stretched, the cells at the top flatten out and when relaxed they become rounded. What is this tissue?
Transitional
Which type of exocrine gland are sebaceous (oil) glands?
holocrine
Mammary glands are classified as apocrine glands. Which of the glands is mammary glands?
compound acinar
Which of the following is not an example of an exocrine gland?
a) sweat glands
b) sebaceous glands
c) mammary glands
d) pituitary gland
e) salivary glands
D
Which type of connective tissue provides the supporting framework for the liver, spleen, lymph nodes, and red bone marrow?
Reticular
All connective tissues consist of two basic elements: cells and__________
Extracellular matrix
Where are mesenchymal cells found?
in embryonic connective tissues
The main adhesive protein of connective tissues is _______
fibronectin
The function of __________ is to store triglycerides
adipocytes
Where would you be able to find dense regular connective tissue in the body?
In tendons and ligaments
This type of connective tissue has no direct blood supply in its extracellular matrix, which makes it slow to heal
reticular
A flat sheet of tissue which covers or lines a body surface (either interior or exterior), and which has both an epithelial and connective tissue layer is called a _________
epithelial membrane
Which of the following is not an epithelial membrane?
a) mucous membrane
b) serous membrane
c) synovial membrane
d) cutaneous membrane
e) lamina propria
C
Which of these serous membranes lines the abdominal cavity and covers the abdominal organs?
a) pleurae
b) pericardium
c) peritoneum
d) cutaneous membrane
e) synovial membrane
C
Which type of muscle tissue would have these characteristics: branched cells, usually has one nucleus, has striations (a striped appearance)?
a) skeletal
b) cardiac
c) smooth
B
Which type of muscle tissue is under the voluntary control of our nervous system. We can consciously control the movement of this type of muscle tissue
Skeletal
Which type of muscle tissue is found in the walls of hollow organs and is not under voluntary control
Smooth
Which part of a neuron typically receives input?
Dendrites
Of the basic tissue types, which types have excitable cells?
muscle and nervous tissues
When a tissue or organ has become damaged; scarring and possible loss of functionality can occur, if ________ cells of the stroma (the supportive connective tissue of that organ) are damaged
fibroblasts
Faster healing with fewer scars in the young can be explained by which of the following factors?
a) better blood supply to tissues
b) better intake of nutrients in a younger person
c) more metabolically active cells
d) all of these are factors in faster and better healing
e) none of these are factors in faster and better healing
D
Tight junctions allow ions, nutrients, and waste products to freely move between cells
False
Collagen fibers are made up of a protein called collagen, which is one of the rarest protein in the body
False
Mast cells are found near blood vessels in connective tissue and release histamine to promote inflammation as a response to injury or infection
True
Mature connective tissues are all present in a newborn
True
Appositional growth of cartilage only occurs in childhood and adolescence
False
Blood has a fluid extracellular matrix with cellular elements in it
True
Each serous membrane is divided into a parietal layer and a visceral layer. The visceral layer is attached to and lines the wall of the body cavity
False
The cells of the nervous system which are able to generate nerve impulses (action potentials) are called neuroglia
False
Tissue regeneration is unlikely to leave a scar if parenchymal cells (the functional cells of the damaged region) are involved with repair
True
Formation of granulation tissue at a wound indicates the person is at higher risk for infection
False
