BSC2085 Anatomy-Physiology 1 Exam 2 Study Guide, Chapters 5 & 6 (Professor Kachlan) PBSC-LW Campus A change from one type of mature tissue to another is called - Answer:metaplasia.
A decubitus ulcer (bed sore) - Answer:occurs when immobilized persons, such as those confined to a hospital bed or wheelchair, are unable to move, and continual pressure on the skin cuts off blood flow to an area.
A gland with secretory cells in both the tubular and acinar portions is called a -
Answer:tubuloacinar gland.
A keratinized - Answer:epithelium has a surface layer of dead cells.
A nonkeratinized - Answer:epithelium lacks the surface layer of dead cells but provides a moist and slippery surface that is well suited to resist stress.
A simple epithelium - Answer:consists of a single layer of cells with every cell touching the basement membrane.
A stratified epithelium - Answer:consists of 2 or more layers of cells with only the deepest layer of cells touching the basement membrane.
Adult stem cells are classified as either - Answer:multipotent or unipotent.
After puberty, the body forms the - Answer:axillary and pubic hair, the male facial hair, and some of the hair on the trunk and limbs.
Apocrine glands are - Answer:the sweat glands that act as 'scent' glands.
Apoptosis or programmed cell death - Answer:is the normal death of cells that have completed their function and best serve the body by dying and getting out of the way.
Basal cell carcinoma is the most - Answer:common type of skin cancer, but it is also the least dangerous because it seldom metastasizes.
Cardiac muscle is - Answer:striated and involuntary.
Cartilage is - Answer:a supportive connective tissue with a flexible rubbery matrix.
Compound glands - Answer:have branched ducts.
Connective - Answer:tissue serves in most cases to bind organs to each other.

Cyanosis is - Answer:blueness of the skin resulting from a deficiency of oxygen in the circulating blood. Erythema is; abnormal redness of the skin caused by increased blood flow in the dilated cutaneous blood vessels.
Dense regular connective tissue - Answer:is named for two properties; the collagen fibers are closely packed and leave relatively little open space, and the fibers are parallel to each other.Collagenous fibers are very abundant in; tendons and ligaments.
Dentritic cells stand guard against - Answer:toxins, microbes, and other pathogens.
Differences in the fibers provide a basis for classifying cartilage into three types -
Answer:hyaline cartilage, elastic cartilage, and fibrocartilage.
Elastic cartilage - Answer:is what gives the shape to our external ear.
Endocrine glands - Answer:secrete hormones into the blood.
Epithelial - Answer:tissue lines body cavities, covers the body surface, and forms the lining of many organs.
Ethnic differences in skin color are primarily caused by differences in - Answer:the quantity of melanin produced, NOT the number of melanocytes.
Exocrine glands - Answer:secrete their product by way of a duct that either opens onto a body surface or into a body cavity.
Fibrocartilage - Answer:is found in the intervertebral discs.
Fibrosis is - Answer:the replacement of damaged tissue with scar tissue, composed mainly of collagen. Scar tissue helps to hold an organ together but it DOES NOT; restore normal function.
First-degree burns involve - Answer:only the epidermis.
Goblet cells are - Answer:unicellular glands that produce the protective mucous coatings which cover the mucous membranes. They are usually found scattered throughout a simple columnar epithelium.
Holocrine glands - Answer:accumulate a product and then the entire cell disintegrates, so the secretion is a mixture of cell fragments and the substance the cell had synthesized prior to its disintegration. The oil-producing glands of the scalp are; holocrine glands.
Hyaline cartilage - Answer:makes up the tip of our nose.
If the duct and secretory portion are of uniform diameter the gland is called - Answer:tubular.
