Answer:

1. Brain

2. Peripheral nerves

Explanation:

The nervous tissue or the nervous system is a system in the humans or animals formed by the neurons.

The nervous system can be categorised into two types based on the structure and functions: the peripheral nervous system and the central nervous system.

The central system of neurons comprises of the neurons present in the spinal cord and the brain and the peripheral system which comprises the nerves of the organs present except the brain and the spinal cord like the nerves in the limbs (legs, arms).

Thus, Brain and Peripheral nerves are correct.

Sergio [31]

Answer:

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.

Explanation:

Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.

<u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.

An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.

On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.

The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.

Which substance on the plasma membrane helps identify chemical signals from outside the cell?

nikdorinn [45]

Answer:

The correct answer is carbohydrate chain.

Explanation:

Plasma membrane contain three types of protein a peripheral protein b transmembrane protein and c GPI anchored protein.

Some membrane protein basically peripheral proteins contain oligosaccharide chain arranged towards the extracellular region of the plasma membrane with respect to the surface of that glycoprotein.

The oligosaccharide chain of glycoprotein play an important role in to identify signals from outside the cell.These signals may include the entry of virus particles inside our body,protein targeting etc.
