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
