What is affected by the electrical signal sent by the third structure? (This will be the fourth structure in the arc.) Where is the cell body of the fourth structure located? What is affected by the electrical signal sent by the fourth structure? (This will be the fifth structure in the arc.) What does the fifth structure do in response to that electrical signal and how does this action protect you? Describe a situation where a reflex arc would be activated that is not described in your lesson. Assume that the reflex arc has five components to it. Please choose a reflex that involves a body part below the neck.

How would antibodies against nicotinic acetylcholine receptors (nAChRs) affect the influx of sodium (Na+) into a skeletal muscle cell?  Group of answer choices These antibodies would target nAChRs for destruction leading to lower sodium influx in muscle cells. These antibodies would target nAChRs, changing their shape to allow calcium instead of sodium through. These antibodies would target nAChRs, changing their shape to allow only potassium through. These antibodies would target nAChRs aiding acetylcholine in its binding to receptors, leading to increased sodium influx in muscle cells.  pick one answer

Choose the type of information that the soft organ smooth muscle first order neuron are sending to the central nervous system: 1, sterogotic information  2, stretch information 3, proprioceptive information 4, temperature information This is the second time in 10 min I asked this question, the fomer one been rejected due to incompleted. But this is the whole inforamtion I had copied from my home work, no letter missed.
