Answer:
The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.
Explanation:
Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.
Answer:
You should give him some form of assurance, as he has no family members to assist him during the ordeal of the surgery. You should also tell him what he needs to be wary of prior to and after the surgery has been completed.
Answer: Parkinson's disease is a progressive nervous system disorder that affect body movement. Symptoms can be barely noticable at first, starting with a tremor in one hand that is barely felt. tremors are common but the disease can also cause stiffness and slowing of movement. Parkinsons disease can not be cured but can be helped with medications such as dopamine promoter, anti-tremor, cognition-enhancing medication, Anti-depression medicine, and physical excercise. Many other medications can be taken to help this disease.
Answer:
The answer to fill in the blank in this question: Some hormones act through cell membrane receptors that stimulate adenylate cyclase activity and production of:____, would be: cAMP.
Explanation:
In the process of hormonal regulation of cells there are two ways in which this can happen: direct activation of DNA inside a cell through steroid hormones, who do not need any kind of mediators to enter the cytoplasm of a cell and activate its genetic material, or indirect activation, which is the common way for non-steroidal hormones, such as epinephrine. In this second scenario a hormone will reach the cell and lock onto a receptor on the plasma membrane. The effect is that a G-protein, which is adjacent to the receptor, activates the second-messenger system, meaning that the activity the hormone came to initiate, will depend on these mediators. the G-protein will then activate adenylate cyclase, which in turn will activate ATP and transform it into cAMP. It is cyclic AMP (cAMP) which will finally relay the original message sent through the hormone, to the genetic material of the cell.
