connective tissue Flashcards
areolar connective tissue
jelly-like matrix
a network of long, branched fibres
adipose tissue or fatty tissue
areolar connective tissue that contains fat
dense, connective tissue
white, non-elastic fibres
functions of dense, connective tissue
as ligaments, it binds bone to bone
tendons bind muscle to muscle, bone, or other structures
forms fibrous sheaths of muscle
forms the membranes around bone and cartilage
yellow, elastic connective tissue
large quantities of yellow, elastic fibres
hyaline cartilage
elastic tissue
jelly-like
contains chondrin
no blood vessels
functions of hyaline cartilage
prevents friction in joints
gives shape to the structures
fibrous cartilage
non-elastic white fibres
cartilage cells in the matrix
white fibrous cartilage
between the bone and muscle
connect muscle to bone
prevents friction
elastic cartilage
contains yellow, elastic fibres
contains chondrin
bone
large quantities of calcium with carbonate and phosphate
collagen ensures that bone is not brittle
lamallae
appear to be layered lamellae arranged around a central canal (Haversian canal)
osteocytes
bone cells
in lacunae
they reach into the canaliculi
lacunae
cavity
between lamellae
they reach into the canaliculi
canaliculi
connect the osteocytes with the haversian canal
canals between bone cells
haversian canal
haversian canals contain blood vessels, a nerve fibre, and a lymph vessel
a number of haversian canals with the lamellae form a haversian system
lamellae
thin layers/plates that are typically arranged in circles around central canals
where to find lamellae
in compact bone tissue and hyaline cartilage
haversian system
bone tissue consists of a number of haversian systems
periosteum
a hard connective tissue membrane
surrounds bone
spongy bone
generally the inside of bony structures has a system of bone platelets
blood
opaque, salty, sticky fluid with a bright red colour when it flows from arteries and a darker red colour when flowing from veins
almost metallic smell
slightly alkaline
blood plasma
the liquid component of blood
inorganic substances
water
salts
gases
organic substances
proteins
glucose
fats
waste products
main function of the blood plasma
- transport blood components
- maintenance of a constant body temperature
- transport of blood corpuscles
three types of blood corpuscles
red blood cells (erythrocytes)
white blood cells (leucocytes)
blood platelets (thrombocytes)
red blood corpuscles
erythrocytes
flat biconcave discs
no nucleus when mature
where are red blood corpuscles produced
in the red marrow of bones
function of red blood corpuscles
transport of oxygen and carbon dioxide
haemoglobin in a compound with oxygen
oxyhaemoglobin
white blood corpuscles
leucocytes
produced by the red marrow, spleen, and lymph glands
play an important role in the immune system
have nuclei
how white blood is classified
granular or agranular
blood platelets
thrombocytes
small discs
without nuclei
the function of blood platelets
forming of clots and clotting of blood
haemophilia
a genetic condition where one of the blood clotting factors is absent
sufferers can bleed to death from a small wound.
