1. Summing incoming neural signals is part of (a) reception (b) transmission (c) integration (d) action by effectors (e) afferent neuron transmission
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.
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.

- You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forwardExplain: Healthy Cell Function Overview→ Briefly describe how a healthy cell usually works: metabolism (ATP production), pH balance, glycogen storage, ion transport, enzymes, etc. Gene Mutation and Genetics Part→ Focus on the autosomal recessive mutation and explain: How gene mutation affects the cell.
