During human embryonic development, the notochord goes on to become the brain and spinal cord.

Alginate is a natural polysaccharide material that forms a very hydrophilic hydrogel that resists protein adsorption, yet due to being a natural material, mammalian cells will recognize it directly.

Jackson has experienced a stroke. He is found to have left hemiparesis (weakness on the left side of the body). He is also having difficulty perceiving vibration on the left side of his body. He can speak clearly and is able to respond to complicated verbal commands. Based on the physical exam findings, what specific area(s) of Jackson’s brain have been damaged as a result of his stroke? [Answer in 2-4 sentences]. 

In the micturition reflex urine is actively expelled from the bladder (smooth muscle). The postganglionic neuron releases acetylcholine, which binds to muscarinic receptors and causes the bladder muscle to contract. In someone who experiences urine leakage (incontinence) would you administer a muscarinic antagonist or agonist. Explain your reasoning.

Jackson has experienced a stroke. He is found to have right hemiparesis (weakness on the right side of the body). He is having difficulty articulating answers to questions asked, speaking only a few words and frequently responding with just a verb or noun.  However, he can respond to complicated verbal commands. Based on the physical exam findings, what specific area(s) of Jackson’s brain have been damaged as a result of his stroke? [Answer in 2-4 sentences].
