The response of an effector is: to counteract the original stimulus that triggered the series of events. What is the purpose of the chemical transmitter in a control system? to enter a cell at a specific receptor site (?) Epinephrine, insulin, and auxins are all examples of ____ that help produce feedback.
Oct 11, 2024 · brain, spinal cord, peripheral nerves. What is the function of the nervous system? it coordinates the body's response to changes in its internal and external environments. What do cells in the nervous system do? they carry messages from one cell to another so that communication among all body parts is smooth and efficient. What are the messages ...
The nervous system enables humans to react to their surroundings and to coordinate their behaviour. It comprises millions of neurones and uses electrical impulses to communicate very quickly.
May 26, 2021 · This question can be addressed on many levels, including sensory processing by peripheral organs and the central nervous system, sensorimotor integration in decision-making brain regions, and motor circuit activation and modulation. Because neuromodulator systems act at each of these levels, they are a useful lens through which to explore the ...
Aug 6, 2015 · Biological regulation is what allows an organism to handle the effects of a perturbation, modulating its own constitutive dynamics in response to particular changes in internal and external conditions. With the central focus of analysis on the case of minimal living systems, we argue that regulation consists in a specific form of second-order control, exerted over the core (constitutive ...

Many signal transduction pathways include protein modification and phosphorylation cascades. IST-3.D.1. Signaling begins with the recognition of a chemical messenger – a ligand – by a receptor protein in a target cell —.
