In a common reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, where does the sign
kobusy [5.1K]

In a reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron. The answer is motor neurons.

<h3>What is the reflex arc?</h3>

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

In general terms,

1) A stimulus of varying nature reaches the body.

2) The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.

3) The CNS processes the information and sends another signal as a response to the stimulus.

Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.

The neurons involved in the mechanism are:

• Afferent or sensorial neurons

• Interneurons

• Efferent or motor neurons

Mode of Action:

  • <u>Ascending branch</u>

The stimulus reaches the body and is received by the specialized sensory receptors.

Afferent neurons, placed in the dermis and epidermis, receive this information from receptors, react and send it to the central nervous system as nerve impulses.

  • <u>Descending branch</u>

Interneurons in the CNS, process the information and send a motor response.  

Efferent neurons carry the response from the CNS to the effector organs, which might be either a muscle or a gland.

Finally, the target tissue responds to the stimulus as a contraction -muscle-,or as hormones release -gland-.

A motor neuron is formed by a cellular body, dendrites (cytoplasmic extensions that receive stimuli from other cells), and a long axon that is capable of conducting the electrochemical signals.

The axon brunches out into several extensions when it approaches the muscle.

At the end of each brunch, the axon is inserted in the muscle fiber surface, composing neuromuscular join.

This is the last part of the NS involved in the process before the muscle contracts.

After a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron, and from there to the effector.  

The corrct answer is motorneuron.

Select the incorrect statement regarding macromolecules found in cells.
Otrada [13]

Answer:

The repeating subunits of DNA are ribonucleotides whereas in RNA they are deoxyribonucleotides.

Explanation:

Ribonucleotides are repeating subunit of RNA while the deoxy-ribonucleotides are repeating subunits of DNA. That why RNA full form represent the ribonucleic acid and DNA represent deoxyribonucleic acid.

Actually the word "deoxy" means one oxygen is removed or less in DNA. The DNA  lacks the one oxygen atom of hydroxyl group at carbon number two of ribose sugar. While RNA have the hydroxyl group at carbon number two of hydrogen atom.

The removal of one hydrogen atom in DNA make it more stable than RNA because DNA is made specifically to store genetic information and needed to be strong. The oxygen atom in RNA makes it vulnerable for attack by other biological molecules.

What would happen without the magnetic field?
telo118 [61]

Explanation:

The Earth's magnetic field protects us by deflecting much of the incoming solar radiation. Without it, our atmosphere would be stripped by solar winds.

Satellites can and do suffer damage from solar storms, and without Earth's magnetic field, every electronic device could be exposed to high-energy particles from cosmic rays and the solar wind. If Earth lost its magnetic field, there would be no magnetosphere and no line of defense, even from weaker solar storms
