TissueThere are four types of tissue:
Epithelial tissueConnective tissueMuscle tissueNervous tissue
Simple squamous epitheliumFunction: passage of
materialsLocation:
glomerulus (kidney), alveoli (lung), endothelium (capillaries)
Simple squamous epithelium from: http://www.bu.edu/histology/i/16002hoa.jpg
Stratified squamous epithelium
Function: protectionLocation: skin,
mouth, esophagus, anus, vagina
Stratified squamous epithelium from: http://www.udel.edu/biology/Wags/histopage/colorpage/cep/cepssq.GIF
Simple cuboidal epithelium
Function: secretion and absorption
Location: tubules of the kidney, glands (e.g. thyroid) and ducts
Simple cuboidalepithelium from: http://science.tjc.edu/Course/BIOLOGY/1409/cuboidal2.6-9.jpg
Stratified cuboidal epitheliumFunction: secretionLocation: larger
glands and ducts e.g. mamary glands

Function: absorption, secretion, protection
Location : stomach, small intestines, uterus
Pseudostratified cloumnar epithelium
Function: secretion Location: respiratory
tract, portion of male uerethra

cilia
Transitional epitheliumFunction:
distensibilty, protection
Location: ureters, urinary bladder, proximal urethra

Fluid/ Liquid connective tissueFunction:
transportationLocation:
cardiovascular system
Blood from: http://lifesci.rutgers.edu/~babiarz/Histo/Blood/Smear2.jpg
Blood
Loose connective tissue
Areolar tissue from: http://www.tvcc.edu/depts/Biology/HotPot/Images/A&P/connective_tissue_loose_areolar.jpg
Areolar tissue Function: surrounds and supports organs; packing
Location: below epithelia e.g. skin, between muscle, around capiliaries
Loose connective tissueFunction: energy
reserve, insulator, cushioning, protection
Location: within joints, breasts, hypodermis; around eyeballs and kidney
Adipose tissue from: http://www.tvcc.edu/depts/Biology/HotPot/Images/A&P/adipose_tissue.jpg
Adipose tissue
adipocytes
Dense connective tissue
Dense regular tissue from: http://www.bu.edu/histology/i/01302hoa.jpg
Dense regular Function: attachment: resist tensile stress; can be pulled in one direction
Location: tendons and ligaments
Dense connective tissueFunction: withstand
tension in any direction
Location: capsules of organs and joints, dermis of skin
Dense irregular tissue from: http://www.pathguy.com/histo/052.jpg
Dense irregular
Structural/ Hard connective tissue: Cartilage
Hyaline cartilage from: http://www.tvcc.edu/depts/Biology/HotPot/Images/A&P/hyaline_cartilage.jpg
Hyaline cartilage Function: flexible support; reduces friction
Location: larynx, trachea, nasal septum, ends of bone
Structural/ Hard connective tissue: Cartilage
Elastic cartilage from: http://www.cytochemistry.net/microanatomy/bone/ecartilage.jpg
Elastic cartilage Function: very flexible; maintains shape
Location: pinna, epiglottis
Structural/ Hard connective tissue: Cartilage
Fibrocartilage from: http://science.tjc.edu/Course/BIOLOGY/1409/fibrocartilage1.6-11.jpg
Fibrocartilage Function: tensile strength; shock absorber
Location: intervertebral disks, pubic symphysis
Structural/ Hard connective tissueFunction:
protection, support, movement, red blood cell formation
Location: bone

Longitudinal section
Skeletal muscle l.s. from: http://clcpages.clcillinois.edu/home/bio567/pages/newtissues/Skeletal%20muscle%2003a.jpg
Characteristics: long, striated, multinucleated, nuclei at periphery, voluntary
Function: movement, generate heat
nuclei
Cardiac muscleCharacteristics:
striated, uninucleated (most times), branched, intercalated disks, involuntary
Function: propels blood
Cardiac muscle from: http://www.cytochemistry.net/08_016.jpg
Intercalated disk
Smooth/Visceral muscleCharacteristics:
lacks stiations, uninucleated, central nuclei, spindle shaped cells, involuntary
Function: propels substances along passageways
Smooth muscle from: http://www.daviddarling.info/images/smooth_muscle.gif
Nervous tissueStructure: dendrite,
body, axonFunction: transmit
electrical impulsesLocation: brain,
spinal cord, nerves
