For the outpatient breast biopsy (I know, different procedure... but as an example) the cost was over $12,000 ($6,000 for the surgeon, $900 for the anesthesiologist, $5,000+ for the hospital use of a room, equipment, drugs, etc) ! Charity care at this hospital covered the use of hospital equipment and the room.
This muscle is named for its trapezoid shape. The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade. Innervation of the trapezius is derived from the spinal accessory nerve.
Muscle spindles are sensory receptors within the belly of a muscle that primarily detect changes in the length of this muscle. They convey length information to the central nervous system via sensory neurons. This information can be processed by the brain to determine the position of body parts.he spindle is a stretch receptor with its own motor supply consisting of several intrafusal muscle fibres. The sensory endings of a primary (group Ia) afferent and a secondary (group II) afferent coil around the non-contractile central portions of the intrafusal fibres.
