emission

 [e-mish´un]
1. a discharge.
2. an involuntary discharge of semen.
nocturnal emission reflex emission of semen during sleep.
thermionic emission the application of heat, such as to a filament, resulting in the emission of electrons and ions.

e·mis·sion

(ē-mish'ŭn),
A discharge; usually referring to a discharge of the male internal genital organs into the internal urethra; the contents of the organs, including sperm cells, prostatic fluid, and seminal vesicle fluid, mix in the internal urethra with mucus from the bulbourethral glands to form semen. Compare: ejaculation.
[L. emissio, fr. e- mitto, to send out]

emission

/emis·sion/ (e-mish´un)
1. discharge (1).
2. an involuntary discharge of semen.

nocturnal emission  reflex emission of semen during sleep.
positron emission  a form of radioactive decay in which a positron (β+) and neutrino are ejected from the nucleus as a proton is transformed into a neutron. Collision of the positron with an electron causes annihilation of both particles and conversion of their masses into energy in the form of two 0.511 MeV gamma rays.

emission

[imish′ən]
Etymology: L, emittere, to send out
a discharge or release of something, as a fluid from the body, electronic signals from a radio transmitter, or an alpha or beta particle from an atomic nucleus during radioactive decay.

emission

The release of a gas, fluid or solid. See Alpha emission Otoacoustic emission.
