1 00:00:01,580 --> 00:00:05,320 Hello kids, today we are going to study the interaction. 2 00:00:06,099 --> 00:00:10,599 The interaction is one of the vital functions that all the living things perform, 3 00:00:11,019 --> 00:00:15,080 and it consists on detecting what is happening in our environment. 4 00:00:16,160 --> 00:00:20,039 The first stage of the interaction is detecting the stimuli. 5 00:00:21,079 --> 00:00:26,920 It consists on detecting the information from outside or inside a body through the senses. 6 00:00:26,920 --> 00:00:37,719 The sense organs and the receptor cells of the sense organs are going to send this information to the next stage, which is coordinating a response. 7 00:00:38,700 --> 00:00:46,859 The nervous system and the brain receive signals from the receptor cells, and the brain coordinates the response by sending orders. 8 00:00:46,859 --> 00:00:54,299 the nerves are made of neurons okay which are is they are these cells that 9 00:00:54,299 --> 00:01:00,520 you can see here that transmit messages through the through nerve impulses the 10 00:01:00,520 --> 00:01:05,359 different parts that we have to study of the neurons are the cell body that it's 11 00:01:05,359 --> 00:01:11,099 also called soma and also the dendrite okay they are going to take this 12 00:01:11,099 --> 00:01:16,739 information the accent okay they are going to take the information and send 13 00:01:16,739 --> 00:01:27,719 it to another neuron once the disinformation is sent to the organs that are going to respond 14 00:01:27,719 --> 00:01:35,560 the responding is made by the effectors which receive the impulses and perform actions these 15 00:01:35,560 --> 00:01:42,760 effectors are part of the musculoskeletal system so this is everything that you have to learn bye
