Neurons (nerve cells) of the central nervous system (brain and spinal cord) are in G0 of the cell cycle and generally do not div

ide in response to an injury. The scientists predict that they can use the data from this experiment to help them treat individuals who suffer from spinal cord injuries. Provide reasoning to support the scientists' prediction.

Answer:

G0 phase is the resting phase for cell. Cells in resting phase do not devide. But they can re- enter to the cell cycle and undergo mitosis.

Explanation:

scientists are working on it. They worked on  fibroblast for their study and they found that these cells started dividing when cultured in appropriate medium. And they found 10% serum  cells cultured for 48 hours gave the 100% DNA replication.

Using this technique  cells can be re generate and connections can be maintained between axons.

Answer:

The reasoning proposed to sustain that Neurons can't reproduce in the case of an injury to attend it is that G0 state of the cell cycle is a stage in which the cell is not preparing itself to divide or will prepare itself to divide.

Explanation:

To understand this answer we need to analyze the context and the proposition. First of all the G0 cell state level is a stage in which the cell is not preparing for division and is not going to prepare itself to divide, so this describes perfectly how neurons won't prepare to reproduce in case an injury is suffered. This trauma situation is a pivot to elaborate on different treatment strategies to restore the functionality of the neuron tissue. Because even though they are damaged they don't recover that way of communicating and need to create another path. This is called neuroplasticity. even though this is a perfect basic piece of knowledge breaking research has found out that neurogenesis is produced but we don't know yet how.

Which of the following is the correct sequence of structures that sound waves pass through on the way to the auditory nerve?
8_murik_8 [283]

The option that correctly indicates the sequence of structures that sound waves pass through on the way to the auditory nerve is: "Pinna → Malleus → Incus → Stapes → Auditory canal → Tympanic membrane → Cochlea → Auditory nerve" (Option B)

<h3>What is the function of the Auditory Nerve?</h3>

The auditory nervous system connects the cochlea to a station in the brainstem (known as the nucleus). Neural impulses pass from that station to the brain, notably the temporal lobe, where sound has meaning and we hear.

Auditory function refers to how a person hears and processes information in difficult-to-understand situations on a daily basis. Children with hearing loss or who have difficulty tolerating noises might benefit from an auditory function exam.
