Complete statement by writing the correct word or words. Axons conduct a nerve impulse away from the cell body. ANSWER: The autonomic nervous system (ANS, visceral nervous system, or involuntary nervous system) is the part of the peripheral nervous system that acts as a control system. Stimulus 3 D) all of the above. Um, neurotransmitter was first bleeding to be the cause of schizophrenia. Mobilization of intracellular calcium and inhibition of specific phosphodiesterases only occur at high non-physiological concentration Anatomy & Physiology: Chapter 11 (The Muscula, Bruce Edward Bursten, Catherine J. Murphy, H. Eugene Lemay, Matthew E. Stoltzfus, Patrick Woodward, Theodore E. Brown. E) B and C. An excitatory post synaptic potential (EPSP) differs from an inhibitory post synaptic potential (IPSP) because the EPSP: B) 5, 2, 3, 1, 4 It is secreted by the sympathetic nervous system and it binds to adrenergic receptors on the post synaptic cell. Serotonin. D) The receptor molecules of the ANS may be muscarinic, nicotinic, or adrenergic. both Na+ and Cl- are in higher concentrations outside the cell.

Na+ and Cl- It is the hormone and neurotransmitter most responsible for vigilant concentration in contrast to its most-chemically-similar hormone, dopamine, which is most responsible for cognitive alertness. Since the early 1950s scientists had found MAO to intercept the action of neurotransmitters, and had developed a class of antidepressant drugs known as monoamine oxidase . The membrane potential at which sufficient voltage-gated Na+ channels open is -60 mV. Sachs BD, et al. E) A and C Drag the terms on the left to the appropriate blanks to complete the sentences. the parasympathetic nerves arise from the brain and part of the spinal cord, and all of the sympathetic nerves arise from the spinal cord. We have a gabba. ANSWER: B) K+ enters the nerve terminal Which of the following represents the voltage that causes a neuron to reach threshold? Your friend exhibits symptoms of ADHD.

K + permeability: The primary determinant of the resting membrane potential Action potentials are initiated by depolarization of the membrane to threshold. myelinated nerves; unmyelinated cell bodies Yes, as the voltage-gated K+ channels open, K+ rushes out of the cell, causing the membrane potential to become more negative on the inside, thus repolarizing the cell. The resting membrane potential moves further away from threshold. Ionotropic receptors such as nicotinic acetylcholine are a group of transmembrane ion channels that open or close in response to the binding of a chemical messenger. The neurotransmitter in this case opens ligand gated Na+ channels. N a Superscript+ ion flow into the neuron increases Furthermore, the statement correctly describes norepinephrine as the neurotransmitter that carries the signal down the spine and affects major organs of the body during the fight or flight response.

Using energy from ATP,sodium-potassium pumpsactively transport ions in both directions across the membrane. voltage-sensitive ion channels on the postsynaptic membrane. What is the value for the resting membrane potential for most neurons? a positive ion is driven into the cell because the inside of the cell is negative compared to the outside of the cell, and Na+ is driven into the cell because the concentration of Na+ is greater outside the cell. Repolarization: Potassium ions are moving out, and the membrane potential is becoming more negative as it moves back toward the resting membrane potential.

B) Has a threshold Rearrange these processes in the correct order in which they occur. Parasympathetic neurons are responsible for releasing norepinephrine on the target organ, while sympathetic neurons are responsible for releasing acetylcholine. The parasympathetic nervous system will be "overridden." The neurotransmitter causes the channel to open, and this can cause a depolarization of the postsynaptic membrane.
