|
What three things are all body tissues made of?
|
Cells
intracellular material fluid |
|
|
what are the four basic tissue types in the body?
|
muscular
nervous epithelial connective |
|
|
what are the three types of muscular tissue
|
skeletal (voluntary/striated)
smooth (involuntary/smooth) cardiac (only found within the heart |
|
|
what is nervous tissue made of and what is its function
|
it is made up of neurons (nerve cells)
its function is to conduct electrical impulses to and from the central nervous system (the brain & spine) |
|
|
what is epithelial tissue?
what does it cover? |
it covers the internal & external surfaces of the body, it also lines the body cavities & forms glands
|
|
|
what are main types of connective tissue? there are 5 types
|
loose connective tissue
dense connective tissue bone blood cartilage |
|
|
where is Hyaline cartilage found, what does it consist of?
|
it is the rings of the trachea & articular surfaces of the joints.
it consists of hyaline matrix chondrocytes fine collagen fibres |
|
|
what is fibrocartilage, what does it have more of?
|
it is very strong similar to hyaline cartilage except it contains mor collagen fibres. it is found between the invertebral discs
|
|
|
what is Hyaline matrix?
|
it is the ground substance that fills the spaces in-between fibres
|
|
|
what are chondrocytes?
|
they are cells that produce cartilage
|
|
|
what is the difference between exocrine & endocrine glands as regards ducts?
|
exocrine have ducts to enable secretion to pass directly to the site of work
endocrine have no ducts so secrections pass into blood stream |
|
|
what do endocrine & exocrine glands secrete (clue they secrete different things)
|
exocrine secrete enzymes, mucous etc
endocrine secrete hormones |
|
|
give examples of endocrine glands & exocrine glands
|
exocrine - nasal cavity, salivary gland, crypts of lieberkuhn
endocrine - islets of langerhans (pancreas), thyroid, adrenal gland |
|
|
describe loose connective tissue with regards:
distribution appearance strength collagen fibres elastic fibres blood supply fat & give examples |
distribution - widely
appearance - greyish/white, bubbly appearance (hence areolar) strength - resonably strong collagen fibres - less dense elastic fibres - more present (more elastic) blood supply - good fat - is widely present LCT known as adipose tissue examples - holds muscle fibres together, supports nerves, connects skin to underlying tissue |
|
|
describe dense connective tissue with regards:
distribution appearance strength collagen fibres elastic fibres blood supply & give examples |
distribution - areas of strength
appearance - white strength - very strong collagen fibres - dense elastic fibres - less present (less elastic) blood supply - poor examples - scar tissue, ligaments, tendons |
|
|
what percentage of the body is made up of fluid?
|
60-70%
|
|
|
what is the main ions of the ECF?
|
sodium (cation), chloride & biocarbonate (anions)
|
|
|
what are the main ions of the ICF?
|
potassium (cation), protein & phosphate (anions)
|
|
|
what is diffusion? what is its aim?
|
the random movement of molecules from a area of high concentration to an area of low concentration. the aim is to get equal distribution
|
|
|
what is osmosis? what does it move?
|
the movement of water from a area of low concentration to high concentration
|
