from what we know about the mitochondria why do you think the muscles and the nervous system are the predominant tissue affect in the disease known as myoclonic epilepsy with reagged red fibers (MERFF)

Myoclonic seizures are characterized by brief, involuntary spasms of the tongue or muscles of the face, arms, or legs. Myoclonic seizures are most apt to occur when waking after a night's sleep.

Myoclonic epilepsy with ragged-red fibers, also known as MERRF is a mitochondrial disorder (therefore, it is maternally inherited) which affects many parts of the body but in particular, muscle and the nervous system.

MERRF is usually characterized by muscle twitches (hence, myoclonus), muscle weakness and generally patients experience progressive stiffness or spasticity.

The medical phrase is "myoclonic tremor". It is caused by either an injury or condition that affects the nervous system, literally the nerves. Myoclonic tremor is often from a spinal injury. Myoclonic refers to the frequency and quality of the tremor, e.g. fast, slow, rhythmic, etc. Myoclonic can be further distinguished as tonic or clonic, which refers to the degree of musle rigidity that occurs during the myoclonic tremor. Note that the words jerk, jerks, or jerking are offensive to a person who has tremors.

Doose Syndrome, known s Myoclonic-Astatic Epilepsy (MAE), is an epilepsy syndrome of early childhood that is often resistant to medication, making it difficult to treat. Seizures originate from all over the brain (generalized) as opposed to coming from one focal area. There is no known cause for the seizures. They can be frequent or rare and they can be serious or mild. It usually starts in the first five yeas of life. Some treatment options are available with some success.
