BSC 2085 Exam 2 UPDATED ACTUAL Questions and CORRECT
Answers
Three basic characteristics of connective tissue 1. Specialized cells (more than 1 cell type present)
2. Solid extracellular protein fibers
3. Fluid extracellular ground substance
What makes up the matrix of connective tissue Fibers and ground substance
Functions of connective tissue 1. Establishing a structural framework for the body
2. Transporting fluids and dissolved materials
3.Protecting delicate organs
4. Supporting, surrounding, and interconnecting other types of tissue
5. Storing energy reserves, especially in the form of triglycerides
6. Defending the body from invading microorganisms
Three general categories of connective tissues 1. Connective tissue proper
2. Fluid connective tissues
3. Supporting connective tissues
Functions of connective tissue proper and examples Connect and protect
(ex: Tendons and adipose tissue)
Functions of fluid connective tissues and examples Transportation
(Ex: Blood and lymph)
Functions of Supporting connective tissues and examples provides structural strength
(Ex: Cartilage and Bone)
Connective Tissue Proper Cell Populations 1.Fibroblasts
2.Fibrocytes
3.Adipocytes
4.Mesenchymal cells
5.Macrophages
6.Mast cells
7.Lymphocytes
8.Microphages
9.Melanocytes
Most abundant cell type found in all connective tissue Fibroblasts
proper
, Which cell type secrete proteins and hyalurnan Fibroblasts
Which cell type is second most abundant found in Fibrocytes
connective tissue proper
Functions of Fibrocytes maintain fibers of connective tissue proper
Functions of adipocytes energy reserve and cushions tissues/organs
What are mesenchymal cells? Stem cells that respond to injury or infection
(Differentiate into fibroblasts, macrophages, etc. in response to injury or infection)
What are macrophages? Large, amoeba-like cells of the immune system
Functions of macrophages Eat pathogens and damaged cells
Two classes of macrophages 1. Fixed macrophages
2. Free Macrophages
Characteristics of Fixed macrophages stay in tissue. Frontline defense, reinforced by free macrophages and other cells
characteristics of Free macrophages migrate through tissue
Functions of mast cells Stimulate inflammation after injury or infection
What do Mast cells release after injury or infection Release:
1. histamine (dilates blood vessels)
to stimulate local inflammation
2. heparin (anticoagulant)
to prevent blood clots in areas of slow blood flow
