Anatomy ch 4- extra credit quiz
Which of the following is NOT an age-related change of tissues?
Collagen fibers decrease in number, yet become more flexible.
In the process of tissue repair, which of the events listed below occurs last?
Granulation tissue develops.
What type of gland accumulates its secretion in the cytoplasm of the cell, with the cell then rupturing and becoming part of the secretion?
Holocrine
Cell ruptures and dies during secretion.
Holocrine gland
Entire cells are shed by the gland and become part of the secretion.
Holocrine gland
Sebaceous (oil) glands of the skin are examples of this type of gland.
Holocrine gland
A student is completing her first anatomy practical and is struggling with the last histology slide. She cannot determine if the slide is of an epithelial tissue or connective tissue. Which of the following is an accurate and helpful clue to determine the tissue type?
If the tissue has an obvious free surface, it is most likely epithelial tissue.
A portion of the cell containing secretory products is pinched off the cell.
Apocrine gland
Milk-producing mammary glands are examples of this type gland.
Apocrine gland
Secretory products are stored in the cells of the gland.
Apocrine gland
Protection against abrasion, barrier against infection
Stratified squamous
Support, attachment of tissues, cushioning, and protection are examples of functions for __________ tissues.
Connective
Which body membrane protects the body from water loss and harm to internal organs?
Cutaneous
Which of the following occurs when the permeability of blood vessels increases during inflammation?
Edema
Cells of the gland produce secretions by active transport.
Merocrine gland
Cells of the gland produce vesicles that contain secretory products.
Merocrine gland
Cells secrete products with no loss of cellular material.
Merocrine gland
Vesicles empty their contents into the duct through exocytosis at the free surface of the cell.
Merocrine gland
Lining of the nasal cavity, pharynx, and trachea
Pseudostratifed columnar
Absorption in the small and large intestines
Simple columnar
Kidney tubules, secretory cells of glands
Simple cuboidal
Indicate the type of epithelium that is best suited for allowing diffusion of substances, as would be found lining the air sacs (alveoli) of the lungs.
Simple squamous
Lining of blood vessels and alveoli of lungs
Simple squamous
Associated with each hair follicle is a small muscle that, when it contracts, changes the angle of the hair relative to the surface of skin. A student has incorrectly identified the muscle tissue as skeletal muscle. Which statement best explains why skeletal muscle is incorrect?
Skeletal muscle is voluntary and the movement of the hairs is involuntary; the correct identification would be smooth muscle.
Mammary gland ducts, larynx, parts of the male urethra
Stratified columnar
Sweat gland ducts, ovarian follicular cells
Stratified cuboidal
Which kind of tissue would you expect to find in an area of the body that experiences friction and wear and tear?
Stratified squamous epithelial tissue
Cervical cancer is often caused by human papillomavirus (HPV) infection and is typically detected by swabbing the cervix (Pap test) and examining the collected cells for abnormal growth. The cervix is covered with an epithelium consisting of many layers of flattened cells. What type of epithelium is being tested?
Stratified squamous epitheliium
What is a collection of similar cells and surrounding substances?
Tissue
Lining of the urinary bladder and ureters
Transitional
The _________ is a thin layer of specialized extracellular material beneath the deepest cells of an epithelium, serving to bind the epithelium to underlying tissue.
basement membrane
Marfan syndrome is a genetic disorder that results in abnormal collagen production. Marfan syndrome is most likely associated with _____ tissue.
connective
A tissue membrane, such as a serous membrane, consists of
epithelium and underlying connective tissue.
Support cells of the brain and spinal cord are called __________.
glia cells
A lab technician is observing a secretion released by an unknown exocrine gland. The secretion includes lipids, proteins, and nucleic acids (DNA and RNA). This gland is
holocrine; the presence of nucleic acids indicates that the secretion involves whole cells.
The secretions of endocrine glands are released directly
into bloodstream
Epithelium, of a single layer, with both tall columnar cells reaching the free surface and shorter basal cells, is called __________ epithelium.
pseudostratified columnar
An epithelial tissue is exposed to constant abrasion and is often stretched during normal activities. This type of tissue is most likely to be
stratified squamous with many desmosomes to connect adjacent cells.
A tissue that has the ability to contract, is not consciously controlled, and has a banded appearance is
striated involuntary muscle.
The various types of epithelium are classified by
the shape of cells and number of cell layers.
Epithelial tissue is characterized by
tightly packed cells.
