Examples of Special Connective Tissue

Study These Flashcards
A
  1. blood
  2. cartilage
  3. bones
  4. adipose
25
connective tissues that serve as packaging and binding material for most organs; connects muscle to bone and attaches bone to bone
Connective Tissue Proper
26
connective tissue that provides support, storage of fats, and transport and defense
Special Connective Tissue
27
other term for loose type connective tissue proper
areolar
28
examples of dense type connective tissue proper
1. tendon 2. ligament
29
examples of loose type/areolar connective tissue proper
1. fascia 2. hypodermis
30
an aggregation of cells with common origin and function
Tissue
31
addition to the 4 major types of animal tissue
blood vascular tissue
32
protective and superficially disposed tissues that line surfaces, tubules, and ducts
Epithelial tissues
33
membranes that are lined with epithelium
Mucus and Serous Membranes
34
consist of cells lined by one basement membrane
Sensory Epithelium
35
falsely stratified epithelium
Pseudo-stratified
36
applied to mucus linings of the lower urinary tract that may be distended or collapsed, according to the amount of urine contained within
Transitional epithelium
37
reveals round, cuboidal cells
Collapsed state
38
Epithelial cells can be classified as ____ or _____ based on the number of layers of cells
1. simple 2. stratified
39
underlined by a single basement membrane
Simple Epithelium
40
made up of layers of cells, each layer underlined by a basement membrane
Stratified Epithelium
41
Epithelium can also be classified based on the shape of the cells in the most superficial layers:
1. Squamous Epithelium 2. Cuboidal Epithelium 3. Columnar Epithelium 4. Transitional Epithelium
42
tissue linings made of thin, flat spherical to polygonal cells on the panoramic view, but fusiform on profile
Squamous Epithelium
43
tissue lining mostly tubules and ducts, as in those of the kidney, and are made up of cells that are cubical or with nucleus that is centrally placed in each cell
Cuboidal Epithelium
44
tissue linings found mostly in the digestive and respiratory tracts, made up of taller than wide cells, with basally located nucleus in each cell
Columnar Epithelium
45
consists of mucosal cells that change in shape when the organ is either distended or relaxed during the tissue preparation
Transitional Epithelium
46
Distension
allows the cells to assume fusiform and flattened cells when viewed in the cross-section of the bladder
47
shape of the cell when the bladder is empty
more cubical and bi-nucleate
48
4 types of Simple Epithelial Tissue
1. Simple Squamous Epithelial Tissues 2. Simple Cuboidal Epithelium 3. Simple Columnar Epithelium 4. Pseudostratified Columnar Epithelium
49
flat polygonal to spherical mucosal linings underlined by a single basement membrane
Simple Squamous Epithelial Cells
50
cubical cells supported by a single basement membrane mucosal lining of tubules and ducts
Simple Cuboidal Epithelium
51
taller than wide cells lined by a single basement membrane
Simple Columnar Epithelium
52
tissue lining made up of cells of various heights, but the location of nucleus varies - some found in the apex, in the base, or near the middle of the cell
Pseudostratified Epithelium
53
Stratified Epithelial tissue includes:
1. Stratified Squamous Epithelium 2. Stratified Cuboidal Epithelium 3. Stratified Columnar Epithelium 4. Transitional Epithelium
54
Stratified Squamous Epithelium can be classified into:
1. Keratinized Squamous Epithelium 2. Non-Keratinized Squamous Epithelium
55
mostly found in the corneal layer of the skin epidermis that are filled with the protein keratin
Keratinized Squamous Epithelium
56
make up the mucosal linings of cavities, such as oral cavity
Non-keratinized Squamous Epithelium
57
consisting several layers of cubical cells that make up glandular tissues, as in those of the mammary glands, sweat glands, and salivary gland
Stratified Cuboidal Epithelium
58
made up of layers of taller than wide columnar cells as those that make up the linings of pharynx, conjunctiva, and urethra of males
Stratified Columnar Epithelium
