Name the four tissue types | Epithelial, Connective, Muscle, Nervous |
Connective Tissue is found where? | In all organs of some sort |
What is Connective Tissue made of? | cells and matrix |
Immature Connective Tissue cells are called what? | "-blasts" |
Mature Connective Tissue cells are called what? | "-cytes" |
Name the two types of Embryonic Connective Tissue | Mesenchyme, and Mucous |
Mucous Connective Tissue is also called what? | Wharton's Jelly |
Fibroblasts are responsible for what? | Synthesize collagen, elastic, reticular fibers, and most of ground substance |
Matrix is made of what? | fibers and ground substance |
Function of ground substance | Fills the space between cells and fibers, and the type of ground substance = type of tissue (jello mould) |
Name the main proteoglycan (part of ground substance) | Hyaluronic acid |
Name the three types of fibers in Connective Tissue | Collagen, Elastic, and Reticular |
Function of Collagen Fiber | Strength (thick and straight) |
Function of Elastic Fiber | Strength and Flexibility (thin/ wavy) |
Function of Reticular Fiber | Strength and support (delicate/ branch) |
Where are collagen fibers found? | Cartilage |
Where are Elastic fibers found? | skin and walls of lungs |
Where are Reticular fibers found? | basement membrane of cells and dermis layer of skin |
What is Scurvy? | Disease resulting from Vitamin C deficiency (Vitamin C needed to make collagen= strength) |
Name the three types of Loose Connective Tissue | Aereolar CT, Adipose tissue, and Reticular tissue |
What are mast cells? | cells found in blood vessels and nerves and places of external environment that respond to injury/ inflammation of body tissues |
Dense Connective Tissue includes: | Regular (parallel), Irregular (multiple directions), and Elastic (sweatpants) |
Where is dense connective tissue found? | tendons, ligaments, skin, lung tissue, and elastic arteries |
What is a type of Phagocytic cell? | Macrophages: they filter blood by engulfing foreign objects |
What makes up dense connective tissue? | collagen and elastic fibers for strength and flexibility |
Name the three types of Cartilage | Hyaline, Fibrocartilage, and elastic |
Where is Hyaline cartilage found? | bone surfaces, trachea, and costal/ nasal cartilages |
Where is Fibrocartilage found? | only in sympheses (pubic, vertebrae) |
Where is Elastic cartilage found? | epiglottis, external ear, ear canal |
What are cartilage cells called? | Chondrocytes |
Where are cartilage cells located? | chondrocytes located in lacunae of bone cavity |
Name the two types of bone | Spongy and Compact |
What does ground substance of blood include? | liquid matrix/ blood plasma |
