A+GRADED. Buy Quality Materials!
Collection of cells of the same type that performs common function
What is a tissue
What are 4 major tissue types in the body
Connective tissue, muscular tissue, Nervous tissue, Epithelial tissue
What do connective tissues do
Binds and supports body parts
What do muscular tissue do
Moves the body snd its parts
What do the nervous tissue do
Conducts nerve impulses
What do epithelial tissue do
Covers body surfaces, lines body cavities
What are the three main components of connective tissue
Specialized cell, ground substance, protein fibers
What are 3 protein fibers
Collagen , elastin and reticular
What is ground substance?
Non cellular between the cells and ranges from solid to fluid
What is matrix made of
Ground substance + protein fibers
What does collagen do
provides flexibility and strength
What does reticular do
Branched to provide supporting network
What does elastin do
Elasticity, it stretches and coils
Components of connective tissues
Adipose cell, Ground substance, Elastic fiber, Stem cell, Collagen Fiber, Fibroblast,
Reticular fiber, blood vessels, white blood cells
adipose cells
store fat
Ground substance
fills spaces between cells and fibers
elastic fibers
Branched and stretchable
stem cells
Divide to produce other types of cells
collagen fibers
Unbranched strong but flexible
Fibroblasts
Divides to produce other types of cells
, Reticular fiber
Branched thin and forms network
white blood cell
engulfs pathogens or produces antibodies
3 Main types of connective issues
Fibrous, Supportive, Fluid
what do fibroblast connective tissues contain
fibroblast, cells with a matrix of collagen and elastic fibers
Loose fibrous tissue
found supporting epithelium and many internal organs.
loose fibrous tissues allow
organs like lungs and arteries to expand
Dense fibrous connective tissue
found in tendons (muscles->bone) and ligaments (bones-> bones)
Connective tissues found in the knees
loose fibrous tissue , hyaline cartilage , dense fibrous tissue , adipose tissue, compact
bone.
Chondrocytes
cells present in champbers called lacunae
Cartilage
lacks direct blood supply , heals very slowly.
Matrix of cartilage
solid but flexible
3 types of cartilage
Hyaline Cartilage, Elastic cartilage, Fibrocartilage
Hyaline cartilage
fine collagen fibers
elastic cartilage
lots of elastic fibers
Fibrocartilage
Strong collagen fibers , whithstand P
kinds of supportive tissues
Bone, Cartilage
Osteocytes
cells present in chambers called lacunae
matrix of bones
solid and rigid , made of collagen and calcium salts
2 types of bone
compact and spongy
what do Compact bone consist of
consist of cylindrical units called osteons .
central canal of compact bone contains
blood vessels and nerves
Spongy bones
lighter than compact bones but stron
2 types of fluid connective tissue
