si alte structuri:
-vase (adventice)
-submucoasa viscere
-muschi,tendoane,peri_ost
unde se gaseste densitate cea mai mare a terminatiilor libere ?


densitatea mare a receptorilor durerii ajuta la ce..?comparativ unde e densit mai mica si la ce duce
densit mare a term.lib se gaseste la nivelul tegumentului


nr mare duce la localizare precisa a durerii cutanate .si de ex caracter vag si imprecis al durerii in viscere..unde densit. lor e mai mica

Hipotalamusul, de cine e controlat ?
de scoarta ..emisferelor cerebrale
Hipotalamusul e constituit din cite feluri de nuclei ?
trei:
anteriori
posteriori
mijlocii
ce sint ganglionii(nucleii) bazali
mase subst cenusie
situati la baza emisferelor
deasupra si lateral Talamus
Emisferele cerebrale sint separate de fisura InterEmisferica
si sint legate in partea bazala prin ce ?

enumerati
sint legate prin formatiuni de substanta alba :
corpul calos
trigonul cerebral(trigone franc.=fornix .engl)
comisurile albe(anteioara si poaterioara)
Motilitate ce inseamna


a cui capacitate(proprietatea) este Motilitatea
capacitatea musculaturii de a se destinde sau contracta


a musculaturii
astenia este




dupa extirparea cerebel se instaleaza cine , Astenia,si mai cine?
oboseala musculara rapida
scorta cerebelului e formata di cite straturi ?

care e cel mai important strat si de ce?

stiind ca sc.emisfere = 2 straturi paleocortex(limbic) + 6 strat neocortex
3 straturi are scoarta cerebel


stratul mijlociu,celule piriforme Purkinje
conecteaza scoarta cereb cu alte etaje Nevrax(SNC)
in cerebel substanta alba se gaseste in interior sau periferie (scoarta)
substa alba e in interior
pt ca scoarta e cenusie

invers decit la maduva
Mesencefalul are 2 functii care sint: ?

care substanta realizeza una si care cealalta ?
functia reflexa si de conducere are Mezencefalul
(de fapt nu numai mezencefalul sau
nu mezencefalul are functiile cnducere si reflexa ci trunchiul si fiecare bulb,punte ,mezencefal au bienteles cele 2 functii)

functia reflexa se realizeza subst cenusie

functia Conducere-subst.alba
ce inseamna tegument ? si cine e

Datorita cui(din ce cauza)
tegumentul(pielea) deserveste mai multe sensibilitati(tactila,termica,dureroasa)?

Cine(ce sensibilatati) are ca stimul comun deformarea Tegumentului ?

In cite moduri se poate deforma tegumentul ?(cite tipuri de deformare a tegumentului se descriu ?..
asociati si denumirea sensibilitatii cutanate respective
tegument - care acopera..pielea

pielea deserveste multe sensibilitati datorita multilor' si variatilor tipuri de Receptori

Sensibilitatea tactila ,presionala ,vibratorie

superficial -in cazul Tactului

profund- presiune

rapid repetat -vibratii

cine powers ' sex drive ..si in barbati
im femei

unde trimite semnale sistemul nervos

(stimulii(impulsurile) sexuale dupa ce au au trecut in sistemul limbic s.n. )dupa ce
testosteronul
it's testosterone that powers the sex drive in both men and women.

de la sistemul nervos la sistemul pelvic
se umfla tesuturile cu singe ..

Given the right balance of hormones, sexual stimuli passes to the limbic lobe of the brain, often called the "pleasure center," which sends signals via the nervous system to the pelvic region. Blood vessels in the genitals are prompted to dilate, admitting a rush of blood that inflates both male and female erectile tissues. Then, the vessels close off, preventing blood from flowing out of the area.

The result is an erection and all the other physical signs of sexual excitement. Simultaneously, neurotransmitters like norepinephrine and dopamine are released from the brain, sending messages of pleasure and arousal throughout our bodies

pt ce trebuie sa facem exercitii ,aerobic, miscare ..
care e resultatul of physical extersion este
eliberarea endorfinelor in creier
care influenteaza cum ne simtim
big boost of our sex life

exercise..don't be surprised if you find yourself feeling in the mood for love
The reason has less to do with getting stronger than with the release of endorphins in the brain (as a result of physical exertion) that influence how we feel.

These are the same neurochemicals responsible for a "runner's high" or the sense of exhilaration that comes from skiing down a mountain or after an intense aerobics class. It turns out these brain chemicals may also be linked to the release of hormones that power the sex drive. Research has shown that women who exercise regularly tend to have more active sex lives, are more easily aroused, and reach orgasm more quickly than those who don't work out.
......
Instead of stimulating brain chemicals to rev up the sex drive, yoga and tantra provide postures designed to help resolve specific sexual problems. Some are said to work by stimulating blood flow to the genital area while others are directed toward maximizing sexual performance and satisfaction.
