Myelitis involving the whole thickness of the spinal cord, but limited longitudinally. Inflammation that spans a specific section of the spinal cord, leading to paralysis and numbness in the body parts receiving nerves from the spinal cord beneath the inflamed area.  

Muscle fibers that can conduct axon potentials along their cell membranes. Almost all skeletal muscle in humans is twitch muscle. A very small number of muscles in humans are tonic muscles.  

A muscle with three tendons of origin and a single, common insertion.  

A flat muscle with a broad origin and narrow insertion.  

Slowly contracting muscle fibers that cannot propagate an action potential along their cell membranes. Tonic muscles are uncommon in humans and found only in the extraocular eye muscles, stapedius muscle (in the middle ear), and intrafusal fibers of the muscle spindles.  

A muscle arising on the inner surface of the thyroid cartilage. It extends upward and backward and is inserted on the epiglottis. It depresses the epiglottis.
