Lab Quiz #4- Histology Cell Locations & Functions

Simple squamous

Capillaries; diffusion, filtration, secretion

Simple cuboidal

Thyroid; absorption, active transport, secretion

Simple columnar

Lines digestive tract; secretion of mucous, absorption

Stratified squamous

Esophagus; protection against abrasion

Stratified cuboidal

Ovary follicle; protection, secretion

Stratified columnar

Large ducts of some glands; protection, secretion

Pseudostratified

Respiratory tract; specialized goblet cells that secrete mucous to coat passageways

Transitional

Bladder; allow stretching as it fills

Loose areolar

Everywhere; anchors skin-tissue, tissue-tissue, around organs/capillaries

Loose adipose

Center of femur; cusioning, insulation, energy storage

Dense regular

Tendons, ligaments, aponeuroses; attach muscle-bone (tendon) and bone-bone (ligament)

Dense irregular

Dermis of skin; strong in all directions

Hyaline cartilage

Covering articular surfaces (eg., end of ribs); provides support and reinforcements

Fibrocartilage

Discs of knee and jaw joint; can absorb a large amount of compressive force

Elastic cartilage

Nose; gives support while remaining flexible

Skeletal muscle

Attached to bones in skeleton (eg., biceps); moves body & maintains posture

Cardiac muscle

Walls of heart; continously pumps blood throughout body

Smooth muscle

Blood vessel walls; pushes substances through organs

Nervous tissue

Brain, spinal cord, nerves; carry electrical signals (action potentials)
