Some species have a special structure called the cephalic ganglion that assists in the functioning of the diffuse nervous system. What is this cephalic ganglion?

chelicerate, diplopod, insect, and centipede.

A high school student, walking through the school gardens, observed some animals and noted the main characteristics presented by these animals, as described below: Animal 1 - Three pairs of legs, one pair of antennas, and body divided into head, thorax, and abdomen. Animal 2 - Four pairs of legs, absence of antennas, and body divided into cephalothorax and abdomen. Animal 3 - Body with several segments, and two pairs of legs per segment and one pair of antennas. Animal 4 - Body with several segments and a single pair of legs per segment, in addition to one pair of antennas. Indicate the alternative that correctly and respectively contains the groups to which animals 1, 2, 3, and 4 belong.

From the stimuli sent by the sensory neurons, the central nervous system has as its main function to send information to the brain, which will process this information so that it can be properly responded to by the human body. What is the other main function of this system?

The nervous system is a complex set of organs that controls and coordinates the functions of our body, being responsible for receiving, interpreting, and responding to internal and external stimuli. Among the organs that make up the nervous system, there are the brain and the spinal cord. Both belong to the central nervous system. In this context, which of the following alternatives is part of the peripheral nervous system?

insect, chelicerate, diplopod, and centipede

Animal 2 - Four pairs of legs, absence of antennas, and body divided into cephalothorax and abdomen. Animal 3 - Body with several segments, two pairs of legs per segment, and one pair of antennas. Animal 4 - Body with several segments and a single pair of legs per segment, in addition to one pair of antennas. Mark the alternative that contains, correctly and respectively, the groups to which animals 1, 2, 3, and 4 belong.

To answer this question, it is necessary to identify the groups of animals based on the provided characteristics. 1) Animal with three pairs of legs, one pair of antennas, and body divided into head, thorax, and abdomen: Insect. 2) Animal with four pairs of legs, absence of antennas, and body divided into cephalothorax and abdomen: Chelicerate. 3) Animal with body with several segments, two pairs of legs per segment, and one pair of antennas: Diplopod. 4) Animal with body with several segments and a single pair of legs per segment, in addition to one pair of antennas: Centipede. Therefore, the groups to which animals 1, 2, 3, and 4 belong are, respectively, insect, chelicerate, diplopod, and centipede.
