• Group of cells similar in structure and function

• 4 types of tissues 1. Epithelial 2. Connective 3. Muscle 4. Nerve

Epithelial Connective Muscle Nerve Credits

• Polarity• Specialized

contacts• Supported by

connective tissue• Avascular but

innervated• Regeneration

Simple Stratified

Very thin Concerned about

absorption Secretion Filtration

Squamos Cuboidal Columnar

• Large• Spherical central

nuclei• Functions in

secretion and absorption

• Present in kidney tubules

Simple Topic Cuboidal Columnar

Single layer of cube-like cells with large spherical central nuclei

Function in secretion and absorption

Simple Tissue Squamos Columnar

• Single layer of tall cells with oval nuclei (many contain cilia)

• Goblet cells are often found in this layer

• Ciliated type line small bronchi

Simple Tissue Squamos Cuboidal

Contain two or more cell layers

Major role of Epithelial Stratified is Protection

Squamos Cuboidal Columnar

Thick membrane Function in

protection Forms the external

part of the skin’s epidermis

Stratified Topic Cuboidal Columnar

Quite rare in the body

Found in some seat and mammary glands

Typically two cell layers thick

Stratified Topic Squamos Columnar

Limited distribution in the body

Also occurs at transition areas between two other types of epithelia

Stratified Topic Squamos Cuboidal

Found throughout the body

Most abundant and widely distributed in primary tissues

Living cells surrounded by a matrix

Proper Cartilage Bone Blood

2 Subclasses - Loose Connective

tissues - Dense Connective

Tissues

Topic Adipose Areolar Dense Regular & Irregular

Areolar connective Tissue

Wrap and cushion organs

Widely distributed throughout the body

Proper Topic Adipose Dense Regular &Irregular

Adipose Connective Tissue

Nutrient-Storing ability is much greater

Richly vascularized, indicating its high metabolic activity

Proper Topic Areolar Dense Regular & Irregular

Parallel collagen fibers with a few elastic fibers

Major cell type is fibroblast

Attaches muscles to bone or to other muscles

Proper Topic Areolar Adipose Dense Irregular

Irregular arranged collagen fibers with some elastic fiber

Major cell type is fibroblasts

Withstands tension in many directions providing structural strength

Proper Topic Areolar Adipose Dense Regular

Both tension and compression

Flexible-providing a resilient rigidity to the structures it supports

Lacks nerve fibers and is avascular

Connective Topic Proper Bone Blood

Chonchorytes lie in lacunae

Supports, reinforces, cushion, and resists compression

Forms the coastal Cartilage

Cartilage Topic Elastic Cartilage Fibrocartilage

Similar to hyaline cartilage but with more elastic fibers

Supports external ear and the epigittis

Cartilage Topic Hyaline Cartilage Fibrocartilage

Matrix similar to hyaline cartilage but less from with thick collagen fibers

Provides tensile strength and absorbs compression shock

Cartilage Topic Hyaline Cartilage Elastic Cartilage

Hard calcified matrix with collagen fibers found in bone

Stores calcium, minerals and fat

Connective Topic Proper Cartilage Blood

Red and white cell in a fluid matrix

Contained with blood vessels

Connective Topic Proper Cartilage Bone

Highly cellular Well-cascularized

tissues that are responsible for most types of body movement

Skeletal Cardiac Smooth

Long Cylindrical Multinucleate cell

with obvious striations

Initiates and controls voluntary movement

Muscle Topic Cardiac Smooth

Branching, Striated uninucleate cells interlocking at intercalated discs

Propels blood into the circulation

Muscle Topic Skeletal Cardiac Smooth

Sheets of spindle shaped cells with central nuclei that have no striations

Found in the walls of hollow organs

Muscle Topic Skeletal Cardiac

Branched neurons with long cellular processes and support cells

Transmits electrical signals from sensory receptors to effectors
