List the 4 types of tissue
The four primary tissues are epithelial, connective, muscle and nervous.
________ tissue is the covering, lining, and glandular tissue of the body.
Epithelial
Name some functions of epithelial tissue.
protection, absorption, excretion, filtration, secretion, and sensory reception.
T/F Epithelial tissues exhibit specialized contacts, polarity, avascularity, support from connective tissue, and high regenerative capacity.
True
_______ is a single layer of squamos cells. Highly adapted for filtration and exchange of substances, it forms walls of air sacs of the lungs and lines blood vessels.
Simple squamos epithelium
_______, commonly found active in secretion and absorption, is found in glands and in kidney tubules.
Simple cuboidal epithelium
T/F Simple Columnar epithelium consists of a single layer of tall columnar cells that exhibit microvilli and often mucus-producing cells. Lines mos of digestive tract.
True
_______ is a simple columnar epithelium that appears stratified and lines most of the upper respiratory passages.
Pseudostratified columnar epithelium
________ is multi-layered, adapted to resist abrasion, and lines the esophagus, vagina, and forms the skin epidermis.
Stratified squamos epithelium
T/F Stratified cuboidal epithelia are rare in the body, and are found chiefly in ducts of large glands.
True
________ is a modified stratified squamos epithelium, adapted for responding to stretch. It lines hollow urinary system organs.
Transitional Epithelium
A ______ is one or more cells specialized to secrete a product.
Gland
Glands are classified as ______ or _______ and are classified structurally as multicellular or unicellular.
Exocrine or Endocrine
_______, typified by goblet cells and mucous cells, are mucus-secreting single-celled glands.
Unicellular glands
________ secrete their products by exocytosis as they are produced. The pancreas, most sweat glands, and salivary glands belong to this class.
Merocrine
Secretory cells of ________ accumulate their products within them until they rupture. Sebaceous (oil) glands of the skin are the only true example.
Holocrine
How are multicellular exocrine glands classified?
By duct and secretory unit types.
______ is found everywhere in the body and is the most abundant and widely distributed of the primary tissues.
Connective tissue
Name the four main classes of connective tissue.
Connective tissue proper, cartilage, bone tissue , blood
T/F Connective tissue's major functions include binding and support, protection, insulation, and transportation of substances within the body.
True
Name some common characteristics of connective tissue.
Common origin, degrees of vascularity, extracellular matrix.
T/F Because of connective tissue's extracellular matrix, it is able to bear weight, withstand great tension, and endure abuses such as physical trauma and abrasion that no other tissue would be able to tolerate.
True
What are the 3 main elements of connective tissue?
Ground substance, fibers, and cells
_____ and _____ make up the extracellular matrix of connective tissue.
Ground substance and fibers
T/F Connective tissue can be delicate and fragile to form a soft "packing" around an organ, or it can form "ropes" (such as tendons or ligaments) of incredible strength.
True
Name the 3 types of fibers found in connective tissue matrix.
Collagen, elastic, reticular
T/F Collagen fibers are the most strong and abundant of the 3 fibers found in connective tissue.
True
Each connective tissue has a primary cell type. Name the primary connective tissues and their cell types.
Connective tissue proper - fibroblasts
Cartilage - Chondroblasts
Bone - Osteoblasts
Blood - hematopoietic stem cell
T/F Loose connective tissue constists of areolar, adipose, and reticular.
True
T/F Connective tissue proper has 2 subclasses: Loose connective tissue and dense connective tissue
True
Name the dense connective tissue.
Dense regular, dense irregular, and elastic
T/F Hyaline cartilage is the most abundant type of cartilage.
True
_____ forms intervertebral discs and knee cartilages.
Fibrocartilage
The external ear is an example of _______
Elastic cartilage
______ consist of elongated cells specialized to contract and cause movement.
Muscle Tissue
Based on structure and function, muscle tissues are _________.
Skeletal, Cardiac, and Smooth
What is the body's 1st response to injury?
Inflammation
T/F The decrease in mass and viability seen in most tissues during old age often reflects circulatory deficits or poor nutrition.
True
The gland type that secretes products such as milk, saliva, bile or sweat through a duct is _______
exocrine gland
T/F Scar tissue is a variety of connective tissue.
True
Inability to absorb digested nutrients and secrete mucus might indicate a disorder in which tissue?
Simple columnar
T/F Muscle tissue is highly cellular and well vascularized.
True
T/F Simple squamos is a single celled layer of epithelium that forms the lining of serous membanes.
True
________ are commonly found wedged between simple collumnar epithelial cells.
Goblet cells
The presence of lacunae, calcium salts, and blood vessels would indicate ______.
Osseous tissue
Organized groups of cells (plus their intracellular substances) that have a common purpose form a _______
Tissue
What are glycosaminoglycans?
negatively charged polysaccharides
T/F Adipose tissue's primary function is nutrient storage.
True
T/F Inflammation causes capillaries to dilate and become permeable.
True
______ within the cartilage, divide and secrete new matrix.
Chondroblasts
T/F Macrophages are found in areolar and lymphatic tissues.
True
T/F Epithelial tissues have the capacity to regenerate.
true
What does not effect the tissue repair process?
Health
Does cartilage tissue heal faster than bone?
No
Intervertebral discs exhibit a large amount of tensile strength to absorb shock bc they possess _____
Collagen fibers
______ appears to have 2 or 3 layers of cells, but all the cells are in contact with the basement membrane.
Pseudostratified columnar epithelium
T/F Muscle is not considered connective tissue.
True
Thyroid glands are ______ .
Endocrine
T/F Merocrine glands are not altered by the secretory process.
True
