Case Study 1. Mr. Stevens’ symptoms, such as frequent loss of balance and the inability to even draw a straight line are indications that the cerebellum, which is part of the brain, is involved. This cerebellum is the part of the brain that has the responsibility of maintaining body balance and posture, among other things. The cerebellum is very important for body balance, as well as in body functions. This is because it plays an important role in the maintenance of body balance and posture. This is possible given that it uses the vestibular receptor in conjunction with the proprioceptors to control commands. It is the motor neurons that are responsible for ensuring that body changes as well as position are maintained (Cerebellum, nd). The cerebellum also is very important in cognitive functions. In addition, once the cerebellum has received information from the sensory system as well as the spinal cord, it regulates different voluntary movements such as speech, coordination as well as muscular activity (Knierim, n.d). Given that Mr. Stevens experiences a loss of balance, then it is definite that there must be cerebellar damage. Even more proof is added to with his inability to draw a straight line, which can be attributed to the inability of proper coordination of muscular activities. In addition, Mr. Stevens asserts that he feels like a drunken man when he is walking, this can be also linked to cognitive functions, a role that is performed by the cerebellum. Thus, Mr. Stevens’ symptoms indicate cerebellar damage.

Case Study 2. The body has its homeostatic way of preparing and reacting towards danger. One of the ways is through the famous ‘fight or flight’ response. This is when in the sight of perceived danger, the body releases adrenalin. This speeds up the pulse rate, slows down the rate of digestion, and blood supply to
