The genus Mus or typical mice refers to a specific genus of muroid rodents, all typically called mice (the adjective "muroid" comes from the word "Muroidea", which is a large superfamily of rodents, including mice, rats, voles, hamsters, gerbils, and many other relatives), though the term can be used for other rodents.
House mouse (Mus musculus) Phase specific vocalizations of male mice at the initial encounter during the courtship sequence. A mouse (pl.: mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate.
Mouse brain, lateral view. The mouse brain refers to the brain of Mus musculus.Various brain atlases exist.. For reasons of reproducibility, genetically characterized, stable strains like C57BL/6 were chosen to produce high-resolution images and databases. [1]
The house mouse (Mus musculus) has a gestation period of 19 to 21 days. Key events in mouse brain development occur both before and after birth, beginning with peak neurogenesis of the cranial motor nuclei 9 days after conception, up to eye opening which occurs after birth and about 30 days after conception.
Mice are the most commonly used vertebrate species, popular because of their availability, size, low cost, ease of handling, and fast reproduction rate. [5] Mice are quick to reach sexual maturity, as well as quick to gestate , where labs can have a new generation every three weeks as well as a relatively short lifespan of two years.

In July 1968, four pairs of mice were introduced into the habitat. The habitat was a 9-foot (2.7 m; 110 in; 270 cm) square metal pen with 4.5-foot-high (1.4 m; 54 in; 140 cm) sides. Each side had four groups of four vertical, wire mesh "tunnels". The "tunnels" gave access to nesting boxes, food hoppers, and water dispensers.
Mice are good jumpers, climbers, and swimmers, and are generally considered to be thigmotactic, i.e. usually attempt to maintain contact with vertical surfaces. [citation needed] Mice are mostly crepuscular or nocturnal; they are averse to bright lights. The average sleep time of a captive house mouse is reported to be 12.5 hours per day.
