Animal's Specialized Structures Flashcards
a group of similar cells that performs a common function
Tissue
Study of animal and plant tissues
Histology
instrument used to cut tissues into ultra-thin sections
Microtome
4 types of tissues found in animals
Epithelial Tissues Cover
Connective Tissues Connect
Muscular tissues contract
Nervous tissue conduct
it may be simple or stratified
Epithelial Tissues Cover
Single layer of cells
Simple epithelium
more than 1 layer of cells
Stratified epithelium
single layer of FLATTENED cells
Simple Squamous Epithelium
Single layer of ELONGATED CELLS
Simple Columnar Epithelium
single layer of CUBE-SHAPED cells
simple cuboidal epithelium
increases the surface are of absorption
Microvili
found in small bronchioles of the respiratory tract for mucus movement
Ciliated simple Columnar epithelium
Columnar cells of tall and thin, forming irregular shapes
Pseudostratified epithelium
Large group of different tissues characterized by having dispersed cells and large extracellular space -extracellular matrix, includes protein fibers such as collagen, elastic, or reticular.
Connective Tissues Connect
Functions of Connective Tissues Connect
-bind and support other tissues
-protection
-filling body space
-storage fats
3 Large Classifications
- Connective Tissue Proper
- Supportive connective tissue (cartilage and bones)
- Fluid connective tissue (blood and lymph)
also called “areolar connective tissues”.
Loose Connective Tissues
packed bundles of collagen fibers with few cells
Dense connective tissues
Made of cells called reticulocytes
Reticular Connective Tissues
-highly elastic (flexible)
-can reach 1.5 times its normal length and then recoil
-provides elasticity to tissues
Elastic Connective Tissues
-store fats
Adipose Tissues
A type of Connective tissue with cells called CHONDROCYTES, separated but strong yet flexible matrix made up of substance called chondrin, a protein - carbohydrate complex
Cartilage
the hardest connective tissue contains cells called osteocytes
Bone
A connective tissue with a liquid matrix called the blood plasma.
