Tissue Types

Question 1

Epithelial Tissue

Answer 1

Structure: Thin sheets of tightly packed cells covering the surfaces and lining of internal organs

Function:
protection from dehydration
low friction surfaces
protection

Examples: Skin, lining of the GI tract

Question 2

Connective Tissue

Answer 2

Structure: various types of cells and fibres held together by a liquid, a solid, or a gel known as a “MATRIX” e.g. extracellular matrix

Fuction: Support and insulation

Examples: Blood, bone, cartilegde, tendons

Question 3

Muscle Tissue

Answer 3

Three Types: skeletial, cardiac, smooth

Strcuture: bundles of long cells called muscle fibres that contain specialized proteins capable of shortening or contracting

Function: Movement (both consious and unconious)

Examples: bicep (skeletal), mayocardium (cardiac), throughout the digestive tract: Peristalsis (smooth)

Question 4

Nervous Tissue

Answer 4

Structure: long thin cells with fine branches at the ends capable of conducting electrical impulses

Function: sensory, communication within the body, coordination of movement & other functions

Examples: brain, nerves in sensory organs
