Functional Anatomy - Integumentary Flashcards
What are the 3 main components of tissue?
Cells, intracellular products and fluid
What are cells?
One type forms the majority and gives the tissue its name
What are intracellular products?
Produced by cells and lie in the spaces between them
What does collagen fibres do?
Give strength
What allows tissue to stretch?
Elastic fibres
What do Mast cells produce?
Histamine
What do macrophages engulf?
Foreign particles
What makes up intracellular products?
Collagen fibres, elastic fibres, mast cells and macrophages
What is the fluid in tissue?
Interstitial fluid flows between the tissues and bathes the cells
What are the 4 main classifications of tissue?
Muscle, nervous, epithelial and connective
What are the protein fibres in muscle tissue?
Actin and Myosin
What are the 3 types of muscle tissue?
Skeletal, cardiac and smooth
What does nervous tissue do?
Controls and coordinates body activity
What are nerve cells called?
Neurons
What is a nerve made up of?
Many neurons held together by connective tissue
Where are nerve tissue impulses sent?
To the CNS
Where does epithelial tissue cover?
Covers the outside of the body
Where does epithelial tissue line?
The body cavities and organs
How are cells arranged in epithelial tissue?
Cells are closely packed together with very little intercellular space
What does the bottom layer of epithelial tissue sit on?
A basement membrane of connective tissue
