- 3) Lucas is a 40-year old man who sustained a Spinal Cord Injury (SCI) in a snow skiing accident 10 years ago. The level of his injury is at C6 – he preserved function below that neurologic level. He cannot walk and he also has some impairment in the arms and hands. He is still able to use a manual wheelchair with his upper limbs’ ability. Lucas is interested in the HandbikeBattle coming up in 2024. This organized event boosts self-confidence and fitness in those who have completed rehabilitation after an injury. Lucas wishes to train this year so that he can think of going to that event. Lucas may need a power-assisted handcycle for the event, but will train with you to be properly prepared. He has not been as active in the past 5 years as he dedicated himself to his work and family and his recovery in rehab. He has a handcycle and a roller as shown below and you have agreed to meet with him to ensure he is performing safely and correctly during his weekly sessions.  a) What…The purpose of the blood-brain barrier includes each of the following except: ____________ . a. protect neurons b. remove toxins c. produce meninges d. prevent bacterial toxins from entering e. provide nutrients and oxygenUnder what conditions could the opening of a chloride channel actually depolarize a neuron rather than hyperpolarize it? i.
