Tissues
Groups of CellsSimilar in StructurePerform common or related functions
Muscle Neurons Epithelia Connective Credits
Muscle Tissue
Highly Cellular Vascular Composed of
Myofilaments Responsible for a
lot of the body’s movement
Smooth Cardiac Skeletal
Skeletal Muscle
Packed by Tissue sheets into organs
Made of long, cylindrical cells
Help with voluntary movement
Attached to bones and occasionally skin
Smooth Cardiac Muscle
Cardiac Muscle
Found in the wall of the heart
Has contractions Uninucleic Have branching cells
that fit tightly together
Made up of titrations
Smooth Muscle Skeletal
Smooth Muscle
No visible titrations Spindle shaped Contain closely
aligned cells which form sheets
In the walls of hollow organs
Muscle Cardiac Skeletal
Epithelial Tissue
Covers body’s surface Forms the outer layer
of the skin Lines the open
cavities of the systems
Covers walls and organs
Simple stratified
Simple Epithelial
Composed of a single layer
Typically found where absorption and filtration occurred
Thin epithelial barrier
Simple squamous Simple columnar Simple cuboidal Psuedostratified
Simple Squamous Epithelial Tissue
Flattened Laterally Disc shaped central
nuclei Simplest of epithelia Found in many body
parts
Epithelial Simple columnar Simple cuboidal Psuedostratified
Simple Columnar Epithelial Tissue
Single layer of tall cells
Round to oval nuclei
Some cells bear cilia
May contain mucus
Simple squamous Epithelial Simple cuboidal Psuedostratified
Simple Cuboidal Epithelial Tissue
Consists of a single layer of cells
Tall wide Spherical central
nuclei
Simple squamous Simple columnar Epithelial Psuedostratified
Pseudostratified Columnar Epithelial
Single layer of cells
Different heights Some do not
reach free surface
Simple squamous Simple columnar Simple cuboidal Epithelial
Stratified Epithelial Tissue
Contain 2 or more layers
More durable than simple epithelial tissues
Major role is protection
Stratified Squamous Stratified Columnar Stratified Cuboidal Transitional
Stratified Squamous Epithelial Tissue
Most widespread of the epithelial tissues
Composed of many thick layers
Protects the body
Epithelial Stratified Columnar Stratified Cuboidal Transitional
Stratified Cuboidal Epithelial Tissue
Rare in the body Found in the ducts
of some of the larger glands
Have 2 layers of cuboidal cells
Stratified Squamous Stratified Columnar Epithelial Transitional
Transitional Epithelial Tissue
Resembles stratified squamous
It has basal cells Dome shaped or
squamous depending
Stratified Squamous Stratified Columnar Stratified Cuboidal Epithelial
Connective Tissue
Found everywhere in the body
Consists of 4 types Has an extra
cellular matrix
Proper Cartilage Bone Blood
Proper Connective Tissue
Divided into 2 subclasses
Includes areolar, adipose, and reticular
Areolar Adipose Reticular Dense Regular Dense Irregular
Areolar Connective Tissue
Support and bind other tissues
Hold body fluids Stores nutrients
and fat Made of a gel like
matrix
Connective Adipose Reticular Dense Regular Dense Irregular
Adipose Connective Tissue
Good at storing nutrients
Made of closely packed adipocytes
Provides reserve food fuel
Supports and protects organs
Areolar Connective Reticular Dense Regular Dense Irregular
Reticular Connective Tissue
Has reticular fibers There are reticular
cells and fibroblasts are scattered along matrix
Supports many free blood cells
Areolar Adipose Connective Dense Regular Dense Irregular
Dense Regular Connective Tissue
Mainly consists of fibers
Closely packed bundles of collagen
Makes up tendons and ligaments
Areolar Adipose Reticular Connective Dense Irregular
Dense Irregular Connective Tissue
Found in body where tension is exerted
Found in skin Forms joint capsules Fibrous coverings
around some organs
Areolar Adipose Reticular Dense Regular Connective
Cartilage
Can stand up to tension and compression
Tough but flexible Lacks nerve fibers Made of 80% water Vascular and aging
cartilage
Hyaline Elastic Fibro Cartilage
Hyaline Cartilage
Most abundant Contains large
numbers of fibers Provides support Found in the
embryonic skeleton
Cartilage Elastic Fibro Cartilage
Elastic Cartilage
Many elastic fibers Found where
stretch and strength are needed
Forms external ear and epiglottis
Hyaline Cartilage Fibro Cartilage
Fibro Cartilage
Has a matrix similar to hyaline cartilage
Made of thick collagen fibers
Absorbs compressive shock
Hyaline Elastic Cartilage
Bone (Osseous Tissue)
Support body structure
Stores fat Many collagen
fibers Supports and
protects minerals
Proper Cartilage Connective Blood
Blood
Develops from mesenchyme
Consists of blood cells
Surrounded by non-living
Located with blood cells
Proper Cartilage Bone Blood
Nervous Tissue
Main component of nervous system
Purpose is to regulate and control body functions
Made of neurons Found in the brain
