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: Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
Answer:
1.5mL
Explanation:
This is 10mg/2mL, which simplifies to 5mg/1mL. To get 7.5mg, you need 1.5mL (multiple numerator and denominator by 1.5).
Answer:
I’m not 100% sure but I believe it’s in your heart
Explanation:
Answer:
The correct answer will be option B-left atrium.
Explanation:
The coronary circulation is the circulation of blood and nutrients to the myocardium of the heart on both sides.
The coronary system consists of coronary arteries and coronary sinus(vein) in which coronary arteries arise from the main artery of the circulatory system called aorta. This aorta arises from the left atrium of the heart which supplies oxygenated blood. These coronary arteries divide into left and right arteries which supply oxygenated blood to the heart.
Thus, option B-left atrium is the correct answer.
