Cremaster muscle
Cremaster Muscle
The Cremaster Muscle (pronunciation: /krɪˈmæstər ˈmʌsl̩/) is a thin layer of skeletal muscle found in the inguinal canal and scrotum in males, and in the inguinal canal in females.
Etymology
The term "cremaster" comes from the Greek word κρεμαστήρ (kremastér) which means "suspender". This is in reference to the muscle's function of raising and lowering the testes in response to temperature changes or stimulation.
Function
The primary function of the cremaster muscle is to control the position of the testes. It contracts to pull the testes closer to the body when they are cold, and relaxes to let them hang further from the body when they are warm. This helps to regulate the temperature of the testes, which is important for sperm production.
