characteristics of connective tissue
- most abundant, able to replicate.
- lots of inorganic intercellular material, produced by cells
- highly vascular, except cartilage.
- 4 gen. purposes (of different types):
- supports/binds other tissues.
- provides for metabolic needs: organs
- manufacture protective/regulatory chemicals
- store nutrients.
loose aerolar purpose
binds organs, holds fluids
dense regular purpose
strong, flexible support.
dense irregular
tensile strength - any direction.
elastic connective purpose
supports, provides framework
reticular connective
stores, provides phagocytic function
adipose purpose(s)
stores fat, insulates.
loose aerolar structure and example
loose, spongy arrangement:fibrocytes and fibres (collagen, elastic, reticular) and matrix.

eg: superficial fascia, beneath skin.
dense irregular structure and example
proportionately more fibres than loose connective tissue, mainly collagen fibres: strength.

eg: intramuscular septa, fibrous organ capsules, joints.
dense regular structure and example
lowest proportion of cells, highest proportion of fibres.
highest tensile strength.

eg. found where subject to *force*: tendons, aponeurosis, ligaments.
elastic connective tissue structure and purpose
mainly branching elastic fibres.
can stretch 1.5 times length.
eg: walls of large arteries and passageways
reticular connective structure and example
network of reticular (lattice) fibres through jelly-like matrix. contains phagocytes - injests foreign materials.

eg: forms framework of spleen, liver, thymus, lymphnodes.
adipose tissue 3 purposes
food reserve, insulator, protects organs.
adipose tissue structure (micro/macro)
stores fat droplets. grouped into lobes separated by fibrous tissue.
adipose tissue found where
around organs, and in hypodermis of skin.
name three types of cartilage
elastic, fibrous, hyaline
what is a lacunae
cavity that a chondrocyte occupies.
where is hyaline cartilage found
articular surfaces of bone, costal cartilage of thoracic cage, trachea and bronchi
which is the most abundant cartilage in the body
hyaline
which type of cartilage is a precursor to bone?
hyaline cartilage
which type of cartilage has a blood supply
NONE.
describe the structure of fibrocartilage
dense matrix with many collagen fibres.
where is fibrocartilage found?
wherever there is a need for a DURABLE and STRONG cartilage: menisci of knee, intervertebral discs, symphysis pubis
what is the structure of hyaline cartilage
homogenous matrix with fine collagenous fibres
what does cartilage do?
is associated with bone, and is a supportive and connective tissue.
where is elastic cartilage found?
outer ear, larynx
what are two kinds of specialized connective tissue?
blood and bone
describe the structure of vascular tissue
BLOOD.
liquid matrix (plasma) intercellular material.
has formed elements within plasma (erythrocytes, leukocytes, and thrombocytes.) (RBC, WBC, platelets)
What is lymph?
filtrate of extracellular fluid
describe the structure of bone tissue
large amount of intercellular material (solid matrix) containint inorganic salts, filled with organic material.
Salts make it strong/rigid, yet organic material makes it flexible.
where are mast cells found?
In loose aerolar connective tissue
what does a mast cell do?
produces chemicals (such as histamines and anticoagulants) that are required by the body
what is a fibroblast
produces fibres within connective tissue. (collagen, reticular, elastic, )
