Connective tissues Flashcards
Learn CT,functions and structures
The 4 classes of Connective tissues are?
CT proper
Cartilage
Bone
Blood
Tissue that give rise to all tissues
Mesenchymal tissue/mesenchyme
Cell that gives rise to blood tissue?
Hemapoietic stem cell
Types of CT proper?
Loose connective
Dense connective
Types of loose CT tissues
Areolar
Adipose
Reticular
Types of Dense CT?
Regular
Irregular
Elastic
Types of cartilage tissue
Hyaine
Fibrocartilage
Elastic
Types of bone tissues
Compact
Spongy bone
Structural Properties of tissues
Tensile strength
Elasticity
Volume
Fibres + ground substance
Extracellular matrix
Fibres and cells found in tissues
Fibres:
CER(Collagen,Elastic and Reticular)
Cells: Mast Macrophage Fibroblasts Adipose Plasma cell
Which cells are fixed
Fibrocyte
Fibroblasts
Adipocyte(fat cells)
Which cells are wandering cells?
Macrophages Monocyte Lymphocytes Plasma cells Mast cells
Fibroblasts?
Fibroblasts secrets fibers+ground substance
Mast cells?
produce histamine that help dilate small blood vessels in reaction to injury
Plasma cells?
antibody secreting cells that arise from b-lymphocytes
Adipocytes
fat cells that secrete triglycerides,They support protect and insulate
Macrophages
phagocytes that develop from monocytes
Four Types of tissues
Epithelial
Connective
Muscle
Nervous
Epithelial
Protection,absorption,secretion
They lack blood vessels
Cover body surfaces and internal organs
Which is the backbone of tissues
Hyaluronic acid
Type 1 collagen
Supporting tendon ligament tissues and skin
Types II
for hyaline cartilage
Areolar T
- structure
- location
- function
A.Consist of all 3 types of fibres
common cells : Fibroblasts & macrophages
B.found in subcutaneous layer,around organs and blood vessels
3.Support and act as biological packing n wrapping materia
Important role in inflammation
Adipose T
- Structure
- location
- functions
A. Adipocytes
B.subcutaneous layer
n the yellow marrow
Around organs(in breasts,around kidneys and eyeballs)
C.Supports,protect and insulate against heat loss
Reticular T
- Structure
- Location
- Function
A.Reticular fibres and cells
B. Spleen,liver and lymph nodes
C.forms stroma of organs that supports other cell types and binds smooth cells together
Dense irregular
Structures?
Forms?
Provides?
A Irregularly arranged collagen fibres
Has fibroblasts
Forms dermis of skin and submucosa of digestive tract
Provide strength attachment
Dense regular
Function?
Location?
Attaches bone to bone,muscle to bones,great tensile stress
Forms tendons,ligaments and aponeuroses
