Microfilaments
Made of repeated subunits of Actin, Able to bind with ATP and ADP, globules
Microtubules
Made of Tubulin, alpha and beta tubulin subunits, able to bind with Guanine nucleotides
Filaments
repeated subunits of keratin
Conducting zone of resp tract
nose, pharynx, larynx, trachea, bronchus, bronchiole
Respiratory zone
deep inside lungs, in aveoli and cap beds, bronchioles
Lower resp tract
bronchiole, alveolar duct, alveoli, trachea, bronchioles
Upper resp tract
nose, pharynx, larynx, trachea
Vestibule
portion of nose that lies post to ext nares
Vibrissae
Large nose hairs embedded in the epithelial lining of nose
When O2 joins with hydrogen to make H2O there is an... sharing of electrons
unequal
A.... Prevents tetnic contractions of cardiac muscle
Long refractory period
.... Consists of commisural fibers carring info between right and left hemi's of brain
Corpus callosum
If damage is to the hair cells at the basal ends of the cochlea pt will experiance...
impaired hearing of high pitched frequency sounds
When the vents are contracting and forcing blood into the aorta and pulmonary artery
Ventricular systole
Regulation in blood pressure
A decrease in bl. vol. leads the nephron JG cells to release renin, which converts to angiotensiogen- to angiotensin1, then changed to angiotensin2 in lung which stim the adrenal cotrex to release aldosterone
Pathway of filtrate thru nephron
Bowmans capsule, prox convoluted tubule, loope of henle, distal convouted tubule
Hering bruer reflex
Prevents overinflation of lungs
responsiveness or irritability
ability to sense changes in the enviro and then react to them
input and output
input- sent via afferent pathways Output-sent via efferent
Sagittal
Cut made lengthwise dividing body into right and left
Transverse
Horizontal cut of the body, seperates top and bottom
Acromial
point of shoulder
cervical
neck region
crural
leg region
coxal
hip
olcreation
posterior surface of elbow
calcaneal
heel of foot
Synthesis reaction
A+B=AB, Occurs when 2 or more atoms or molecules combine to form a larger mor e complex molecule (Growth)
Decomposition Reactions
AB= A+B, opposite of synthesis react. Molecules are broken down into a simplier form
ATP Function
Provides a form of chem. energy, used by all body cells, modified nucleotide, energy released as glucose catabolized, captured & store
ATP Cycle
ATP-->ADP+p+E Bonds rupture by hydrolysis, energy and phosphate is released.
Chromatin/ Chromosomes
Loose network of bumpy (protien) threads scattered thru the nucleus*** important in cell division
Tight junctions (feature of plasma mem)
Impermeable junctions that bind cells together
Demosomes (feature of plasma mem)
Anchoring junctions, prevents from being pulled apart
Gap Junctions (feature of plasma mem)
Seen in the heart and in embryonic cells, function to allow communication
Mitochondria
Sausage shaped organelles
POWERHOUSES
Produse most of ATP used by body cells
Ribosomes
Made of protien and actual site of protien synthesis
Rough endoplasmic reticulum
studed with ribosomes, building materials of cell membrane formed either in it or on it. Abundant in cells that export protein products
Smooth Endoplasmic reticulum
function in lipid metabolism (cholesterol and fats) and aids in detox
Golgi apparatus
function to modify and package protiens sent by ribosomes. Traffic directors
Cyto skeletons
Microfilaments
Microtubules
Osmosis
Diffusion of H2O thru selectively permeable mem such as plasma membrane
Osmotic pressure
tendency to pull H2O in
Tonicity
Ability to change size and shape of cells by altering amount of H2O
Isotonic solutions
same concentration and H2O as cells do. D5W, lactate ringers
Hypertonic solutions
Contains more solutes or disolved substances that are inside the cell cell shrinks
Crenate
when cells shrink d/t hypertonic solution
Hypotonic solutions
contains very little solutes
Cytokinesis
division of the cytoplasm
Cleavage furrow
due to contractile ring mad of fillament cleav furrow appears over the midline of the spindle, eventually pinches the original cytoplasm into 2 parts
rRNA
Decoder of DNA
mMRNA
messanger of DNA
tRNA
transfer RNA molecules
Amino acids
make up DNA
Transcription
involves the transfer of info from DNA's base sequence into complimentary base sesquence of mRNA
