mi-chau napísal:ale je to sval, len nie hocaky

//kinjeril: Preto som ti napisal, ze nie je sval, ako sval. Su rozne typy svalov. UTFG! ^^

There are three types of muscle:

    * Skeletal muscle or "voluntary muscle" is anchored by tendons to bone and is used to affect skeletal movement such as locomotion and in maintaining posture. Though this postural control is generally maintained as a subconscious reflex, the muscles responsible react to conscious control like non-postural muscles. An average adult male is made up of 40–50% of skeletal muscle and an average adult female is made up of 30–40%.
    * Smooth muscle or "involuntary muscle" is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, and blood vessels, and unlike skeletal muscle, smooth muscle is not under conscious control.
    * Cardiac muscle is also an "involuntary muscle" but is a specialized kind of muscle found only within the heart.

priamo v penise nie... na zaciatku mocovej rury a pri prostate su, ale z hladkeho svalstva...

keby boli v penise svaly, to by znamenalo, ze by ste s nim mohli robit hocico ine, lebo by bol penis ovladany volou, nie?

alebo som tych x rokov co studujem zle studovala? kokos, asi vratim diplom

asi uz nebudem komentovat to, co sa komentovat neoplati

The corpus spongiosum runs along the underside of the penis and surrounds
the urethra. Posteriorly it widens into a bulb (bulb of the penis),
while anteriorly it ends in the glans penis (Fig. 11.1a). The bulb of the
penis is covered by the two bulbospongiosus muscles, which are joined
in the midline. They help to express the content of the urethra. The dorsum
of the penis is formed by the two corpora cavernosa, which are separated
by a connective tissue septum. Two crura (legs) attach the corpora
cavernosa to the pubic rami. All three cavernous bodies are surrounded
by a dense white connective tissue sheath that is about 1−3mm thick
(tunica albuginea) (Fig. 11.7).
Structure of the Penis
The structure of the penis is determined principally by the blood-filled
spaces of the cavernous bodies (Fig. 11.7). The paired cavernous body of
the penis is a spongy network of collagen and elastic fibers lined with
endothelium. When empty, the spaces are slits; when they are filled
with blood, they attain a diameter of several millimeters. The corpus
spongiosum, on the other hand, is mainly filled with a dense network of
veins.
In the middle of each cavernous body runs an artery (deep artery of
the penis, arteria profunda penis), of which the branches run a helical
course (helicine arteries). They run into the spaces of the corpora cavernosa
and their ends can be occluded. From the spaces, veins that can be
occluded run through the tunica albuginea and drain into the dorsal vein
of the penis.

Doris napísal:v preklade z anglictiny su to spongiovite dutinkate svaly, ale to nie je sval sam o sebe....su to dutinkate utvary, pisala som uz o tom...
a ze su okolo mocovej rury, som tiez spominala...a ze je to hladka svalovina, to tu uz bolo tiez...tak neviem...

ob3l1x napísal:kedze mocova rura ide stredom vsetko je v jej okoli nemyslis ?
sval nie je sval ? skus to povedat nejakemu vasemu profesorovi co ti na to povie ... (podla mna ti ukaze kde su dvere)
ale vazne by ma zaujimalo ako vysvetlis ze sval vlastne nie je sval ...

Doris napísal:poviem to po lopate... sval, ktory pracuje na zaklade vzruchov a podnetov, t.j. priecne pruhovany ma inu strukturu, upina sa na slachu, prebieha tam iny typ nervovych vlakien a pod.
a v hladkom svalstve, co je pripad, ktory tolko rozpitvavame...je to uuplne inak...je tam iny typ nervovych vlaken, clovek ho nemoze ovladat volou, neupina sa na slachu..
preto nie je sval ako sval

mi-chau napísal:Tvrdite mi tu ze motor diesel nieje motor lebo za motor sa povazuje iba benzinovy... to je cela veda, vo ftakoch mame svaly ale nemozeme s nimi zamavat priatelkam na rozlucku, este niekto ma nejasnosti?

SchYzo napísal:hej...ako to ze pri vzruseni je taky tvrdy? tie svaly sa musia aj stiahnut nie? lebo len od krvi by nebol taky tuhy si myslim skuste naplnit balonik vodou a uvidite ze tvrdy nebude

/edit:dneska mi to nemysli vobec, dufam ze sa chapeme

mi-chau napísal:asi sa stiahnu a co ako? vyvracia to teoriu ze tam su?
/baon je roztazny az kym nepraskne, kdezto penis ma svoju "maximalnu kapacitu krvi", ak tam teda vznikne nejaky tlak tak stvrdne, mozno ani stahovanie svalov netreba..
