(krē-mas'tĕr mŭs'ĕl) [TA]
Origin, from internal oblique muscle and inguinal ligament; insertion, cremasteric fascia (spermatic cord); action, raises testicle; nerve supply, genital branch of genitofemoral; in the male the muscle envelops the spermatic cord and testis; in the female, the round ligament of the uterus.

Spasm of the cremaster muscle is the factor most frequently associated with testicular dislocation, which can retract the testis out of the scrotal sac.
First, local superfusion with fMLP (N-formyl-L-methionyl-L-leucyl-L-phenylalanine, 1 [micro]M), a potent chemoattractant and integrin activator [5, 22], induced additional leukocyte adhesion in cremaster muscle venules of WT and [RAGE.sup.-/-] mice, but not of [Icam-1.sup.-/-] mice.
Second, mice were injected with the CXC chemokine CXCL1, also known as keratinocyte-derived chemokine (KC), for triggering additional leukocyte adhesion in exteriorized cremaster muscle venules [5,22].
The mouse cremaster muscle was chosen for intravital imaging, as it can be locally stimulated by exposure to fMLP after exteriorization [10].
To this end, superfusion of murine cremaster muscles with SB203580 (100 nM) for 30 min prior to and for 1 h following the placement of KC gel did not significantly modify the rolling flux and rolling velocity of neutrophils as compared to the control saline-superfused cremaster muscle (P > 0.05; Figures 1(a) and 1(b)).
The testicular artery supplies the perirenal fat, ureter and external iliac lymph nodes; while in the inguinal canal, it supplies the cremaster muscle. [2]
Call it the Apotheosis of the Descended Scrotum, for, as Barney has explained, the cremaster muscle after which these films are named alters the height of men's testicles, moving them closer to or farther from the body to control their temperature.
The cremaster muscles are the muscles that control the height of the testicles, which usually varies with changes in temperature.
