2. Baby Ming is learning to crawl. He also likes to pull himself onto window sills, gnawing on the painted wood of his century-old home as he looks out the windows. Lately his mother, an anatomy and physiology student, has noticed some odd behavior and took Ming to the pediatrician. Blood work determined that Ming had a high level of lead in his blood, ingested from the old leaded paint on the window sill. The doctor indicated that lead poisoning is a type of demyelination disorder. Why should Ming's mother be concerned?

- What are the different nerve roots in the body? Both upper extremity and lower extremity. How can I memorize this?arrow_forwardWrite an explanation for what has happened to your friend.arrow_forwardThis assignment is designed to get you thinking about the functions of some of the structures in the central and peripheral nervous system. Listed below are different symptoms or complications that can be attributed to something from the nervous system. List the specific structure that is most likely the root cause of the pathology. In addition, label which branch of the nervous system that structure is a part of (CNS or PNS). I suggest making a table with the pathology in one column, the affected structure in the next column, and the nervous system section in the final column. Two examples are below. It is possible that more than one answer could be correct. Pathology/Patient Specific Structure CNS or PNS?

She landed awkwardly on her back and an X-ray shows she shattered a vertebra near the bottom of the thoracic region (the T-11 vertebra; mid-lower back). Unfortunately, the break crushed her spinal cord in the region, and now her brain is no longer able to send or receive signals through spinal nerves below the fracture. Which body parts are LEAST likely to be paralyzed by this horrific accident?arrow_forwardIdentify the parts of a neuron or a brain that correspond to the given functions below. The parts are found inside the grid and loop these words either horizontally, vertically, diagonally or inversely. 1. controls the growth of a nerve cell 2. carry impulses or messages toward the cell body 3. carry messages away from the cell body 4. serves as the body’s life support system 5. coordinates muscle movement 6. responsible for mental processes 7. controls breathing, heart rate and swallowing 8. controls the movement of the eye 9. regulates breathing and helps control eye movement 10. serves as a relay station for sensesarrow_forward
