Question
Chapter 16.4, Problem 8CYU
Summary Introduction
To review:
The type of central nervous system cell that can become phagocyte.
Introduction:
The monocytes on maturation form the macrophages. The macrophages are crucial for the initiation of the immune response. The macrophages are one of the phagocytic cells and are found in the lungs, lymph nodes and liver. The macrophages engulf the antigen and present it on the surface. This is done with the help of specific molecules such as a cluster of differentiation and major histocompatibility complex.

16. Neurons that process similar kinds of information are organized into what are called “neuron or neuronal pools.”Different ways of processing information occurs in these pools, depending on their function, and how they are organized. What are the two types of processing of information described below?___________________________________One neuron stimulates the next, which stimulates the next, and so on; the most clear cut example of this type of processing would be innate reflexes.___________________________________ This type of process can activate many pathways simultaneously, and is essential for high-level processes such as complex thinking and problem solving.

- Visit this site (http://openstaxcollege.org/l/neurolab) to see a virtual neurophysiology lab, and to observe electrophysiological processes in the nervous system, where scientists directly measure the electrical signals produced by neurons. Often, the action potentials occur so rapidly that watching a screen to see them occur is not helpful. A speaker is powered by the signals recorded from a neuron and it pops each time the neuron fires an action potential. These action potentials are firing so fast that it sounds like static on the radio. Electrophysiologists can recognize the patterns within that static to understand what is happening. Why is the leech model used for measuring the electrical activity of neurons instead of using humans?arrow_forwardOrdering: put these steps of interneuronal communication in the right order: ________________________Neurotransmitters attach to a ligand-gated ion channel. ________________________Ca++ channels open and let Ca++ enter a dendrite. ________________________Synaptic vesicles release neurotransmitters into the synaptic cleft. ________________________Synaptic vesicles bind to the synaptic cleft. ________________________IPSP or EPSP formed.arrow_forward12.
