Connective Tissue Flashcards
most abundant tissue in body of animals
connective
structure of connective tissue
three components: matrix, cells and fibres
what cells occur in matrix of connective tissue
fibroblasts, macrophages, mast cells, adipose cells, etc
in all connective tissues except _____, the cells secrete fibres made of structural proteins called _______ or ______
blood
collagen
elastin
collagen and elastin provide what to the tissues
strength
elasticity
flexibility
three types of connective tissue
loose
dense
specialised
types of loose connective tissue
areolar
adipose
types of dense connective tissue
dense regular
dense irregular
types of dense regular connective tissue
tendon
ligament
types of specialised connective tissue
skeletal
fluid
types of skeletal connective tissue
bone
cartilage
types of fluid connective tissue
blood
lymph
often areolar connective tissue serves as a support framework for ________
epithelium
location of areolar connective tissue
beneath the skin
matrix of areolar connective tissue is made up of
fibroblasts, macrophages, mast cells
functions of fibroblast in areolar tissue
produce and secrete fibres
adipose tissue is a ___________ connective tissue
fat storing
how are these fat cells in adipose tissue formed
excess of nutrients which are not used immediately are converted into fats and are stored in this tissue
location of adipose connective tissue
mainly beneath the skin
which cells are completely packed in matrix of dense connective tissue
fibres and fibroblast cells
structure of dense regular connective tissue
collagen fibres are present in rows between many parallel bundles of fibres
tendons join
muscle to bone
ligaments join
bone to bone
dense regular connective tissue consist of parralel bundles of _____________
collagen fibres
location of dense irregular connective tissue
skin
cartilage are found more abundantly in ______
vertebrate embryos
in matrix of cartilage are fluid-filled substances called
lacunae
lacunae in cartilage contain which cells
cartilage forming cells called chondrocytes
location of cartilage
tip of nose
outer ear joints
between adjacent bones of vertebral column, limbs and hands in adults
what gives bones its strength
calcium salts and collagen fibres
in long bones such as limb bones, a cavity called as _______ is present
bone marrow cavity
the bone marrow in some bones is the site of production of ________
blood cells
location of bones
forms endoskeleton of adult vertebrates
function of bones
provides structural framework to the body
supports and protects softer tissues and organs such as brain, lungs, etc
provides surface for attachment of muscles and thus helps in locomotion
functions of fluid connective tissue
transport of various materials
blood comprises of
plasma which contains rbc, wbc and platelets
