What causes cremaster muscle?
The cremaster reflex can be stimulated by rubbing a nerve on the inner thigh and by emotion, such as fear and laughter. The cremaster is also activated by a cold environment. If the cremaster reflex is strong enough, it can result in a retractile testicle, pulling the testicle out of the scrotum and up into the groin.
What does cremasteric reflex mean?
The cremasteric reflex is a superficial reflex found in human males that is elicited when the inner part of the thigh is stroked. Stroking of the skin causes the cremaster muscle to contract and pull up the ipsilateral testicle toward the inguinal canal.
What is function of Cremasteric muscle and Dartos muscle?
By contracting simultaneously, the dartos and cremaster muscles can elevate the testes in cold weather (or water) moving the testes closer to the body and decreasing the surface area of the scrotum to retain heat.
What is the function of the Cremasteric muscle?
Transient retraction of the testis out of the scrotum is a normal reflex caused by contraction of the cremaster muscle. This muscle functions to regulate the temperature of the testis and to protect it from extrinsic trauma.
What does a cremasteric reflex look like?
The cremasteric reflex is a superficial (i.e., close to the skin’s surface) reflex observed in human males. This reflex is elicited by lightly stroking or poking the superior and medial (inner) part of the thigh—regardless of the direction of stroke.
What causes sperm testosterone?
The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
What is the medical definition of the cremaster muscle?

Is the spermatic cord a part of the cremaster muscle?

How does the cremaster muscle draw up the testicles?
cremaster muscle. a slip of muscle detached from the internal oblique muscle and passing through the inguinal canal; attached to the vaginal tunics of the spermatic cord the muscles are effective in drawing up the testicles when injury threatens.
