Summary Introduction

Introduction: Neural transmission in the animals takes place by an efficient system, which is the nervous system. The information is taken up by the neurons that transmit the information to the brain for interpretation and then responds. The information is described in the form of stimuli that is detected by neural receptors. Neurons transmit the information to the central nervous system (CNS). The processes involved in neural signalingare reception, transmission, integration, and action by effectors that brings about the actual response.

Answer to Problem 1TYU

Correct answer: Integration is the part of the nervous system, which sums up the incoming neural signals. Hence, the correct answer is option (c).

Explanation of Solution

Reason for the correct answer:

Integration involves sorting and interpreting the incoming neural signals. Here, the final summing of neural signals takes place where it determines the correct response for each signal.

Option (c) is given as “Integration”.

The final summation of the neural signals from afferent neurons is called integration, where the neural signals are interpreted. Hence, the correct answer is option (c).

Reasons for incorrect answers:

Option (a) is given as “Reception”.

Reception is the process of the nervous system where the incoming signals are received by the sensory receptors. Hence, option (a) is incorrect.

Option (b) is given as “Transmission”.

Signals after being received by the sensory receptors are transmitted to the afferent nerve, which transmits the signals to the CNS. In this process, only the transmission of neural signals occurs. Hence, option (b) is incorrect.

Option (d) is given as “action by effectors”.

Effectors respond after the signals are integrated and the response is sent to the effectors. They work after the summation of neural signals. Hence, option (d) is incorrect.

Option (e) is given as “afferent neuron transmission”.

The neural signals after being received by the sensory receptors are transmitted to the afferent neuron, which carries the signals to the CNS for interpretation and integration. Hence, option (e) is incorrect.

Hence, options (a), (b), (d), and (e) are incorrect.

Conclusion

In the process of neural signal transmission in the nervous system, the summation and interpretation of the incoming neural signal take place in the integration process that interprets and then determines the appropriate response.
