Lecture 1: Types of Tissues Flashcards
What are the 4 basic tissues of the body?
Epithelial tissue, Connective tissue, Muscle Tissue, Nervous Tissue
What does Epithelial tissue do?
Covers exposed surfaces, lines internal passage ways and chambers. And forms secretory glands
Provides protection and sensation, and specialised secrition.
Controls permeability
What 2 components does Epithelial tissue include
Epithelia and glands
What does connective tissue do?
Fills internal support
Provides structural support
Stores energy
What does nervous tissue do?
Conducts electrical impulses
Carries information
What does muscle tissue do?
Contracts to produce movement
What does muscle tissue include
muscle tissue includes skeletal muscle, cardiac muscle, and smooth muscle
What are the three types of connective tissue
Connective tissue proper
fluid connective tissues
supporting connective tissues
What are the two types of connective tissue proper
Loose and Dense
What are the two types of fluid connective tissues
Blood and Lymph
What are the two types of supporting connective tissue
Cartilage and Bone
Apart from the heart, what other parts of the body do we find cardiac muscle
Blood vessels such as veins that provide blood supply to the body
What basic tissue includes blood and lymph?
Connective tisssue (Fluid)
What is lymph
Lymph is a clear, watery fluid that carries white blood cells, nutrients, and other substances throughout the body.
What basic tissue forms glands?
Epithelial tissue
What basic tissue allows information to be sent quickly around the body?
Nervous tissue
What basic tissue can be divided into skeletal cardiac and smooth
Muscle tissue
What basic tissue is the most common in the body? (and the least common)
Muscle is most common, nervous is least
What is the most common connective tissue in adults
Areolar tissue (Loose connective proper). It is the general packing material of the body. It is the least specialised and most common
What is Reticular tissue
Reticular tissue provides a framework for other cells. It forms a tough flexible network that provides support and resists distorsion
What part of neurons is responsible for electrical communication
Axon (long bit)
Where are the dendrites on the neuron and what do they do
The end of the cell body (tree branches). They recieve information mainly from other neurons
What are the two types of cells that make up nerve tissue
Neurons and Neuroglia
What is the function of Neuroglia
They maintain structure
repair nervous tissue framework
Perform phagocytosis (eating dead or foreign or ‘bad’ cells)
Provide nutrients to neurons
Regulate the composition of the interstitial fluid surrounding neurons
What is the difference between loose and dense connective tissue proper
They are both fibres, the difference is in the packing.
Loose is Fibres that create loose open framework. Dense is densely packed fibres
