• Amyotrophic lateral sclerosis (ALS) - A progressive disorder where nerve cells break down and muscles weaken.
• Bell's palsy - : Sudden muscle weakness and drooping in one half of your face.
• ·         Hemifacial spasm - Involuntary contractions (twitches) on one side of your face.
• ·         Internuclear ophthalmoplegia - Loss of ability to move your eyes in sync when you look to the side.
• ·         Oculomotor palsy - Damage to your third cranial nerve that causes one of your eyes to stay positioned as though you are looking down and out to the side.
• ·         Stroke - Interruption to blood supply in your brain because of a blood clot or ruptured (burst) blood vessel.
• ·         Traumatic brain injury - Disruption or damage to brain function, often because of a sudden and violent blow to the head.
• ·         Trigeminal neuralgia - Chronic pain in your fifth cranial nerve, which runs through your Cheek.
• Ventral Body Cavity

   

  -The larger cavity located toward the front of the body, and it contains visceral organs (or guts)

  It has 2 main parts:

  -Thoracic cavity

  -Abdominopelvic cavity
• Dorsal Body Cavity

  -Located toward the back of the body, and it houses our central nervous system

  has 2 main parts:

  The cranial cavity (superior), which houses the brain

  The vertebral cavity (inferior), which houses the spinal cord
•  

  Thoracic cavity - (chest cavity)

          Superior (higher) to the abdominopelvic cavity It contains organs such as the heart, lungs, trachea, and esophagus
• • Mediastinum - contains pericardial cavity (heart), trachea, esophagus, thymus gland
•  

   

  Left Pleural Cavity - (houses left lung)
