as everyone knows‚ is what happens when some thing is placed on the tongue. A more technical definition is that it is the direct detection of chemical composition‚ usually through contact with the tongue. The tongue is the muscle that has different nerves on it that relay information to the brain‚ via the nervous system. This information is put back together and depending on your likes and dislikes‚ you either spit the food out or keep eating. Brandt 4 The tongue is covered with chemoreceptor

for this lab we can examine these effects with aid of a finger pulse transducer and a bar stimulus electrode. The finger pulse transducer generates a force peak amplitude that displays the extent to which a muscular twitch responds to a nerve stimulus‚ and nerve frequency. Therefore‚ the purpose of this lab was to observe how the motor unit recruitment in contractile

INTRODUCTION Pediatric nursing or child health nursing is the specialty nursing care of infants‚ children and adolescents. Pediatric nursing is an excellent career for those who love kids and don’t mind hard work. The day of a pediatric nurse can be hectic‚ working with patients that range from newborns to teenagers. No two days are ever the same. Pediatric nurses work mostly on the pediatric halls in hospitals‚ although some may also work in a doctor’s office. The work involved

and act as safety devices to avoid the grinding hence wearing of successive vertebrae. If‚ unfortunately due to physical trauma the cartilaginous ring of a disc ruptures and displaces‚ it is called a disc slip. This protrusion presses upon a spinal nerve‚ emerging from the spinal cord in between the vertebrae‚ causing severe pain and unability to move. Prolonged rest on a hard bed and use of painkillers help repair this damage. [pic] Osteoarthritis: Osteoarthritis is a degenerative joint disease

along the outer ear and vibrate tympanic membrane. This vibration is transferred along the malleus‚ incus‚ and stapes. The mechanical vibration is then taken up as energy by the inner ear and is transmitted as an action potential along the auditory nerve to the brain‚ where it is interpreted. There are two main types of deafness: conductive and perceptive. These are divided into many other types based on their cause‚ symptoms‚ treatment. Conductive hearing loss occurs when conduction of sound through

PROCEDURE FINDINGS The left transverse carpal ligament was moderately thickened‚ and it was causing moderate compression of the left median nerve in the carpal tunnel.

the pupil‚ it travels straight to the rods and cones without having to bounce off the back of the eye. The light travels through the rods and cones and then through the many neurons. By the time the light reaches the optic nerve‚ it is already out of the eye. Since the optic nerve is not in the eye‚ there is no blind spot that occurs. For this reason‚ evolutionists believe that the verted eye is superior to the inverted eye. They say that this design is much more practical and makes much more sense

The electrical indications begin when unique receptor cells‚ on the ends of peripheral nerve fibers‚ know that injury or damage is taking place. The peripheral nervous system is the portion of the nervous system that contains the nerves and ganglia outside of the brain and spinal cord. These receptor cells give out their cautionary indications along the peripheral nerve fibers‚ which then transmit the signal to the dorsal horn of the spinal cord‚ which is the main highway for
