Tissue Flashcards
Tissue
Group of specialised cells with a common function
Components
Cells, Intercelular components, fluid
Classification
Muscle, Nervous, Epithelial, Connective
Muscle Tissue
Contractil with Actin and Myosin
Classification of muscle
Smooth, cardiac, striated
Nervous tissue
Made out of neruons, controls and coordinates the rest of the body
Epithelial tissue
covers and lines, cells closely packed with basement membrane
Functions of epithelial tissue
protect, absorb, secrete
Arragment of cells (epithelial)
simple or stratified
Shape of cells (epithelial)
cuboidal, quamous, columnar
simple squamous
blood vessels, air sacs
simple cuboidal
gut and respiratory tract lining
simple columnar
gut and respiratory tract lining
pseudostratified ciliated cells
nasal cavity
stratified swuaoums
skin
stratified columnar
anus
transitional epithelium
bladder and urethers
glandular tissue
modified epithelial tissue
exocrine glands
have contact with the exterior via a duct
endocrine glands
no connection with the exterior
classification of ducts of glands
tubular, saccular, colled/ simple, compound
mixed gland
found in the pancreas
connective tissue
cells widely separated in a viscous fluid with fibres embedded (matrix)
functions of connective tissue
bind, support, transport, store energy, separate, attach
categories of connective tissue
loose, dense, bone, blood, cartilage
loose connective tissue
many cells in a loose network with collagen and elastic fibres. blood and nerve supply
Dense connective tissue
cells closely packed with collagen fibre and little matrix , great for strenght
classification dense connective tissue
rregular and irregular
Cartilage
collagen and elastic fibres, made up of chondrocytes with no blood supply (perichondrium)
types of cartilage
hyaline, elastic, fibro
bone
forms the skeleton and provides protection for internal organs
blood
carry nutrients, oxygen adn waste products. Plasma with products
