It is in fact the most massive muscle of the human body. The glutes, as they are commonly known, are a group of three muscles located at the back of each hip or buttock.

Tourette's syndrome occurs along a spectrum of tic disorders, which includes transient tics and chronic tics. The exact cause of Tourette's is unknown, but it is well established that both genetic and environmental factors are involved. Genetic studies have proved that the overwhelming majority of cases of Tourette's are inherited, although the exact mode of inheritance is not yet known, and no gene has been identified.
Although vocal and motor tics are the hallmark of Tourette syndrome, such other symptoms as the expression of socially inappropriate comments or behaviors, obsessive compulsive disorder, attention deficit disorder, self-injuring behavior, depression, and anxiety also appear to be associated with Tourette syndrome.he cause of Tourette syndrome is unknown, although some studies suggest that the tics in Tourette syndrome are caused by an increased amount of a neurotransmitter called dopamine. A neurotransmitter is a chemical found in the brain that helps to transmit information from one brain cell to another.
