Q

Column shaped cells.
Oval nuclei at near base.
Nonciliated n ciliated

A

Simple columnar epithelium

22
Q

Columnar cells with microvilli at their apical surface or goblet cells. Mucus serves as lubricant.

A

Nonciliated simple columnar epithelium

23
Q

Columnar epithelial cells with cilla at the apical surface

A

Ciliated simple columnar epithelium

24
Appears to have several layers due to nuclei are various depths. Ciliated cells bear cilia
Pseudostratified columnar epithelium
25
Keratinized form contain the fibrous protein keratin
Stratified Squamous Epithelium
26
Fairly rare type of epithelium. Functions in protection. Salivary and sweat glands
Stratified Cuboidal Epithelium
27
Columnar cells in multiple layers. Functions in protection and secretion. Male urethra and anus
Stratified columnar epithelium
28
Found only in the urinar system
Transitional Epithelium
29
Secretions, called hormones, diffuse directly into the bloodstream
Endocrine Glands
30
Secrete products into ducts that empty onto the surface of epithelium
Exocrine Glands
31
Secretions of the exocrine gland include mucus, sweat, oil, earwax, saliva.
Exocrine Glands
32
Binds tissues together. | Supports and strengthen tissue
Connective Tissue
33
Extra cellular matrix is the material located between the cells. Consist of protein fibers and ground substance.
Extra cellular matrix of Connective Tissue
34
Between cells and fibers. | Fluid, semifluid, gelatinous, or calcified.
Ground Substance (connective tissue extracellular matrix)
35
Functions to support and bind cells, store water, and allow exchange between blood and cells.
Ground Substance (connective tissue extracellular matrix)
36
Collagen fibers: protein collagen, provides strength/ flexibility. Elastic fibers: protein elastin, provides stretching capacity. Reticular fibers: protein collagen and glycoprotein, provides support
Fibers (connective tissue extra cellular matrix)
37
Cells. Fibers. Ground substance.
Connective tissue components
38
Most widely distributed in the body. | Contains several types of cells and all 3 fibers.
Loose Connective Tissue: Areolar
39
Contains adipocytes. | Good for insulation and energy reserves.
Loose Connective Tissue: Adipose
40
Fine interacting reticular fibers and cells. | Forms the stroma (c.t. Of an organ) of liver, spleen, and lymph nodes.
Reticular connective tissue
41
Contains numerous, thicker, and dense fibers.
Dense Connective Tissue
42
Bundles of collagen fibers n regularly arranged in parallel. Tendons and most ligaments.
Dense Regular connective
43
Collagen fibers are usually irregularly arranged. | Dermis of skin and heart.
Dense Irregular Connective Tissue
44
Contain branching elastic fibers. Strong and can recoil to original shape after stretching. Lung tissue and arteries.
Elastic Connective Tissue
45
Cartilage is a dense network of collagen fibers and elastic fibers firmly embedded in chondroitin sulfate.
Cartilage
46
Cartilage cells found in the spaces called lucunae.
Chondrocytes
47
No blood vessels or nerves, except pericondrium.
Cartilage
48
Most abundant cartilage in the body. Provides flexibility and support. Reduces friction. Location is costal cartilage in the rib cage.
Hyaline Cartilage
49
Chondrocytes are scattered among bundles of collagen fibers within the extra cellular matrix. Strongest type of cartilage. Found in intervertebral disc (between vertebrae)
Fibrocartilage
50
Chrondrocytes are located within a threadlike network of elastic fibers.
Elastic Cartilage
51
Bone composed of cells, mineral salts and collagen fibers.
Bone Tissue
52
What is the building block of bone tissue?
Osteon or haversian system (compact bone)
