|
Connective tissue |
Binding tissues together, support and strengthening tissues Protecting internal organs Transport Storage Insulation |
|
|
Matrix |
Ground substance and protein fibres E.g collagen and minerals |
|
|
Loose ct-areolar tissue |
Location: under skin Function: attaches skin to underlying structures |
|
|
Looses CT: adipose tissue |
Location: under skin, surrounding many organs Function: provides insulation, protects against knocks, chemical storage |
|
|
Dense connective tissue |
Very few cells Numerous thick Dense fibres Fibres packed close |
|
|
Dense CT: regular |
Location: tendons, ligaments - collagen fibres in parallel patterns for strength Function: strength in 1 direction |
|
|
Dense CT: elastic |
Location: arteries, lungs Function: strong, recoil to original shape after stretching |
|
|
Cartilage |
dense network of collagen fibres embedded in ground substance. few cells scattered throughout ground substance |
|
|
Cartilage: Hyaline cartilage |
Location: covers ends of bones at joints, forms costal cartilage (joins ribs to sternum), forms rings on trachea Function: Absorbs shock and reduces friction at joints |
|
|
cartilage: Fibro cartilage |
Location: in inter-vertebral discs, anterior pelvis Function: hold bones together and absorbs shock |
|
|
Cartilage: Elastic cartilage |
Location: part of external ear, epiglottis Function: provides strength and elasticity, maintains shape |
|
|
Bone Tissue |
Cells and matrix Matrix - fibres and ground substance (mainly Ca Ph) |
|
|
Bone tissue: Spongy bone |
arranged in an irregular network lots of small spaces often filled with red bone marrow Location: in the ends of long bones and within most short bones |
|
|
Bone tissue: Compact bone |
Location: makes up external layer of all bones Function: able to resist compression and tension |
|
|
Blood |
Made of red and white blood cells, cell fragments (platelets) and liquid matrix Liquid matrix made of ground substance (plasma) and dissolved fibres (fibrinogen) |
|
|
Blood |
Location: Within heart and blood vessels Function: red blood cells - carry oxygen White blood cells: help provide immunity from some diseases Platelets - help prevent blood loss Plasma - Transport dissolved substances |
|
|
Epithelial Tissues |
covers body surfaces lines hollow organs, body cavities packed close together |
|
|
Simple squamos |
single layered - squashed Location: filtering units of the kidneys, air sacs in lungs, blood capillaries Function: rapid diffusion of substances |
|
|
simple cuboidal |
single layered cube shaped Location: kidney tubules, ovaries function: secretion, absorption |
|
|
simple columnar |
Single layered column shaped Function and location: with cillia - move mucus (Uterine-fellopian tubes) with microvillie - involved with absorption (small intestine) |
|
|
pseudostratified columnar |
single layered column shaped, many contain cilia and goblet cells location: upper respiratory tract function: mucus traps inhaled particles and cilia move the mucus |
|
|
goblet cells |
secrete mucus |
|
|
stratified squamos |
keratinised and non keratinised outer layer is flat deeper cells continuously divide and push new cells towards surface and they die |
|
|
straftified squamos |
keratinized - protein (keratin) makes tissues waterproof and very resistant to wear and tear non-keratinized - found lining wet surfaces exposed to the exterior |
|
|
transitional |
Location: found only in urinary system Function: allow hollow structures to expand without causing damage to the tissue |
