Chapter 4- Tissues Flashcards
Exam 2
Study of tissues
Histology
4 Primary Tissues
Epithelial Tissue
Connective Tissue
Muscle Tissue
Nervous Tissue
Tissue that lines body cavities and cover surfaces
Epithelial Tissue function
Epithelial cells adapted to form glands called
Glandular epithelia
Type of gland, secretes products onto hollow organs/ducts and secrete onto the surface of the skin
Exocrine glands
Exocrine gland that keeps skin plyable by oil secretion
Sebaceous gland
Exocrine gland that releases sweat to make you cooler in dry environments
Sweat gland
Type of glad, secretes products (hormones) into the blood for distribution in the body
Endocrine glands
Epithelial cell Classification is by
Shapes and Number of layers
Epithelial cell Shape Classification (3 types)
1) Squamous 2) Cubidal 3)Columnar
Epithelial cell type, fattened cell, line vessels, part of lungs, body surface
Squamous Cells
Epithelial cell type, cube shaped, form lining of tubules (kidneys), and glands
Cubidal Cells
Epithelial Cell Type, column shaped, line respiratory, digestive, and reproductive tracts
Columnar Cells
Epithelial Cell # Layer Classification (2 types)
1) Simple (single-layered)
2) Stratified (multiple-layered)
Multiple layered
Stratified
Single Layered
Simple
Non cellular layer directly beneath epithelial tissue, provides structural support
Basement Membrane
Groups of cells with common functions
Tissues
Type of tissue, contains cells embedded in non-living extracellular matrix, matrix provides the strength
Connective Tissues
Tissue type that supports softer organs of body, connects parts of body, stores fat, and produces blood cells
Connective tissues
