Which of the following statements does NOT accurately describe a characteristic of the autonomic nervous system?
den301095 [7]

Answer:

e. All of the choices describe characteristics of the ANS.

Explanation:

The autonomic nervous system is a regulatory and control system that influences the functions of internal organs.

Autonomic pathways consist of two types of motor neurons, these are the preganglionic neuron and the postganglionic neuron.

ANS stimulation of involuntary effectors is always excitatory. In the preganglionic autonomic neurons, and all postganglionic parasympathetic neurons are usually (cholinergic i.e receptors that bins with acetylcholine), as a result they release acetylcholine as a neurotransmitter. The cholinergic effects of  preganglionic autonomic neurons are always excitatory.

The postganglionic neuron lies entirely in the peripheral nervous system.Yes!, this is so because the ganglion cells that give rise to postganglionic axons lies through the gray rami communicans and join the peripheral nerves of the peripheral nervous system.

True.

Explanation:

The cytoskeleton is also known as the cell skeleton that helps in the movement of the cell organelles. Three different types of cytoskeleton are microtubules, microfilaments and intermediate filaments.

The microtubules shows different function in different cell stages. During prophase stage of the cell cycle, the microtubules gets increase in length. During anaphase stage of the cell cycle , the nonkinetochore microtubules increase in the length the kinetochore microtubules gets short.  During telophase stage of the cell cycle, the nonkinetochore microtubules gets disassemble.

Thus, the answer is true.
