1) If the musculocutaneous nerve is severed, is elbow flexion still possible? Why? 2) What motions of the elbow would be hindered if the ulnar nerve were severed? 3) Tennis elbow is caused from inflammation of the tendons on the lateral epicondyle. Describe what repetitive movements cause this condition and explain why tennis elbow is not actually an elbow injury. 4) If the median nerve is impinged at the elbow, what will be the resulting motor deficits? Is finger flexion...

The sensory systems, including the visual, auditory, somatosensory and pain, taste and olfactory (chemical senses), and vestibular are covered in this module. Students examine how we use these to interpret the world around us and study the importance of these senses to our successful functioning and survival. Considering the information you learned so far, if you had to give up one of your senses, which one would you give up and why? Provide your reasoning and support it with evidence....
