25
Location: urinary bladder, ureter, urethra
Transitional Epithelium
26
Function: accommodate fluctuation of volume of the liquid in an organ
Transitional Epithelium
27
Is the most abundant & widely distributed tissue
Connective Tissue
28
What are the three types of connective tissue
Connective tissue proper, supporting connective tissue, fluid connective tissue
29
Consists of relatively few protein fibers that form a lacy network, with numerous spaces filled with ground substances & fluid
Loose connective tissue
30
This is where the basement membrane of the epithelial tissues often rest
Loose Connective tissue
31
3 kinds of loose connective tissue
Areolar, reticular, adipose
32
Has extracellular matrix consisting mostly of collagen fibers & a few elastic fibers
Areolar Tissue
33
The most common cells is fibroblasts (responsible for producing the matrix)
Loose connective tissue
34
Where are areolar tissues located?
Location: glands, muscles & nerves in the skin
35
What is the function of an Areolar Tissue?
Function: support & nourishment
36
Large cells that are closely packed & a small amount of extracellular matrix
Adipose tissue
37
Adipose tissue contains?
Fat cells or adipocytes
38
Contains large amounts of lipid for energy storage mostly of collagen and reticular fibers & a few elastic fibers
Adipose tissue
39
What is the function and location of adipose tissue?
Function: thermal insulator, energy storage & protection Location: mesenteries, renal pelves, around kidneys, colon surface, mammary glands
40
It has a branched and mesh-like pattern, often called reticulum, due to the arrangement of reticular fibers (reticulin)
Reticular Tissue
41
What is the function and location of reticular tissue?
Function & location: forms the framework of lymphatic tissue, such as in the spleen, lymph nodes, and as well as in bone marrow & liver
42
Consists of many closely packed, thick, collagenous fibers & a fine network of elastic fibers; it has relatively few cells mostly fibroblasts
Dense connective tissue
43
What are the two major categories of dense connective tissue?
Elastic and Collagenous
44
The collagen fibers are oriented in the same direction like in tendons and ligaments
Dense Regular Collagenous Tissue
45
The fibers are oriented in many different directions as in the dermis and organ capsules
Dense Irregular Collagenous Connective Tissue
46
Matrix of collagen fibers & elastic fibers are oriented in the same direction like in the vocal cords
Dense Regular Elastic Connective Tissue
47
3 kinds of supporting tissues
Cartilage, bone and blood
48
Composed of chondrocytes (cartilage cells) located in spaces called lacunae (small spaces)
Cartilage
49
3 types of cartilage
Hyaline, fibrocartilage, elastic cartilage
50
Clear or glassy; the most abundant type of cartilage
Hyaline Cartilage
51
Covers the ends of bones where they come together to form joints
Hyaline cartilage
52
Has more collagen than hyaline cartilage
Fibrocartilage
53
Found in the disks between vertebrae and some joints (knee and jaw)
Fibrocartilage
54
Contains elastic fibers in addition to collagen & proteoglycans
Elastic cartilage
55
Provides rigidity with even more flexibility; found in the external ears, epiglottis & auditory tubes
Elastic cartilage
56
Able to return to its original shape after being stretched
Elastic Cartilage
57
A specialized form of connective tissue made up of blood cells & is surrounded by a non-living fluid called plasma
Blood
58
What is the non-living fluid found in the blood?
Plasma
59
What is the function of the blood?
It functions to deliver nutrients & oxygen to the cells & transports waste away from the same cells
60
Hard connective tissue that consists of living cells & mineralized matrix
Bone
61
Supports & protects tissues & other organs
Bone
62
Two types of bones
Compact and Spongy Bone
63
It is a specialized tissue which functions for contraction
Muscle tissue
64
What are muscle cells composed of?
Composed of long, cylindrical cells called muscle fibers or muscle cells or myocytes
65
3 types of muscle tissue
Cardiac, skeletal and smooth muscle
66
Striated (alternating series of bands or stripe), voluntary muscle
Skeletal Muscle Tissue
67
Muscle fibers are long cylindrical & multinucleated
Skeletal Muscle Tissue
68
Striated, involuntary muscle
Cardiac Muscle Tissue
69
Muscle fibers are short branching fibers; have a single centrally located nucleus
Cardiac Muscle Tissue
70
are fused end-to-end by intercalated disks
Cardiac Muscle Tissue
71
Non-striated, involuntary muscle
Smooth Muscle Tissue
72
Muscle fibers are spindle-shaped (fusiform); have a single centrally located nucleus; and are generally parallel with one another
Smooth Muscle Tissue
73
Where can smooth muscles be found?
Found in the walls of the hollow organs like intestines, stomach & uterus
74
It is the main tissue component of the nervous system
Nerve cells
75
