Stratified cuboidal
27
Found in the larger duct glands and male urethra
Stratified columnar

46
3 types of loose connective tissue
Areolar tissue, adipose tissue, reticular connective tissue
47
5 types of specialized connective tissue
Hyaline cartilage, elastic cartilage, fibrocartilage, bone, blood
48
The function of this tissue is to wrap and cushion organs
Areolar loose connective
49
The location of this tissue is widely distributed under epithelial tissue of body
Areolar loose connective
50
Soft, pliable tissue
Areolar loose connective
51
Contains all fiber types
Areolar loose connective
52
Can soak up excess fluid
Areolar loose connective
53
The function of this tissue is to provide and store fuel, insulate, and support and protect organs
Adipose loose connective
54
The location of this tissue is under skin, around kidneys and eyeballs
Adipose loose connective
55
Matrix is an areolar tissue in which fat globules predominate
Adipose loose connective
56
Many of these cells large lipid deposits
Adipose loose connective
57
This tissue is composed of thin, reticular fibers in a three-dimensional network. it helps provide the framework of certain internal organs, such as the liver and spleen
Reticular connective tissue
58
This tissue consists of many densely packed, thick, collagen fibers and a fine network of elastic fibers. It has few cells, most of which are fibroblasts.
Dense connective tissue
59
3 types of specialized tissue
Cartilage, blood, bone
60
A rigid connective tissue that provides support, frameworks, and attachments, and protects underlying tissues and form structural models for many developing bones
Cartilage
61
Dense network of elastic fibers and thus is more flexible than hyaline cartilage. It provides framework for the external ears and for parts of the larynx.
Elastic cartilage
62
A very tough tissue, has many collagen fibers, a shock absorber for structures that are subjected to pressure
Fibrocartilage
63
A type of tissue that harbors bone marrow, aids in protection, and mineral storage
Bone tissue
64
A type of tissue that transports nutrients and oxygen to the body
Blood tissue
65
Type of tissue found in the brain, spinal cord, and nerves
Nervous tissue
66
Neurons are the cells responsible for action in this system
Nervous system
67
The function of this tissue is to send and receive electrical signals
Nervous tissue
68
Responsible for supporting the neurons. Maintains a clean and healthy environment and can carry out phagocytosis
Nervous tissue
