|
|
Diffusion
|
random movement of solute molecules down a concentrations gradient from an area of high solute concentration to an area of low solute concentration
|
|
|
Osmosis
|
Passive movements of solvent molecules from an area of high concentration to an area of low concentration across a semi permeable membrane
|
|
|
osmotic pressure of a 40% glucose solution
|
1*0.082*298k*(2.22-0)= 54.3
|
|
|
Osmole
|
refers to the number of particles in a solution, expressed as osmoles/L
|
|
|
ACTH
|
fasting would cause the release of a tropic hormone who's indirect effect would cause an elevation of glucose levels.
|
|
|
Mineralocorticoids
|
regulate kidney function by controlling the balance between minerals and water in the blood
|
|
|
Androgens
|
are reproductive hormone's-- testosterone or estrogen
|
|
|
Glucocorticoids
|
influence metabolism of most cells and provide resistance to stressors as well as mobilize amino acids and glucose to keep blood sugar levels fairly constant.
|
|
|
Autonomic reflex
|
reflexes that are mediated via the autonomic nervous system and not under conscious control. Muscles stimulated are smooth muscles, cardiac muscles and glands. Pupillary reflex.
|
|
|
Somatic Reflex
|
reflexes that involve stimulation of skeletal muscles via the somatic nervous system and are under conscious control. Patellar reflex
|
|
|
reflex arc
|
1. receptor
2. sensory neuron 3. interneuron 4. motor neuron 5. effector |
|
|
Monosynaptic reflex arc
|
stretch reflex is-- patellar, Achilles', brachi, and triceps
|
|
|
Polysynaptic reflex arc
|
have at least one interneuron interposed between the afferent and the efferent neurons. Flexor reflex
|
|
|
Meissners corpuscle
|
light touch
|
|
|
free nerve ending
|
temp or pain
|
|
|
pacinian corpuscle
|
deep pressure
|
|
|
root hair complex
|
hair deflection
|
|
|
auricle (pinna)
|
collects sound waves
|
|
|
external auditory canal (meatus)
|
directs collected sound waves towards the tympanic membrane (ear drum)
|
|
|
tympanic membrane (ear drum)
|
separates outer from middle ear, sound waves cause it to vibrate at the same frequency as the sound waves hitting it.
|
|
|
Auditory Ossicles
|
transmit and amplify vibrations from the ear drum to the oval window.
|
|
|
Auditory tube
|
connects the middle ear to the nasopharynx. function is to equalize air pressure on both sides of the tympanic membrane.
|
|
|
conduction deafness
|
is the result of a physical barrier blocking the conduction of sound to the fluids of the inner ear. ear wax
|
|
|
sensorineural deafness
|
is the result of damage to neural structures of the middle ear. concerts.
