First, cells must migrate to their final position, second, these cells must be specified to be neurons , third, the neurons must make connections with their targets, and fourth, the neurons refine their synaptic connections.
What is the early stage in the development of the nervous system called?
Early development
In a process called neurulation , the neural folds curve upward and fuse to form the neural tube, which will eventually become the CNS. The neural plate also forms the neural crest, cells of which will later migrate to different parts of the body and become most of the cells in the PNS and ANS.

Information-processing models involve three processes: encoding, storage, and retrieval .
What are the steps of the information processing cycle?
The sequence of events in processing information, which includes (1) input, (2) processing, (3) storage and (4) output . The input stage can be further broken down into acquisition, data entry and validation.
What are the types of information processing system?
There are various types of information systems, for example: transaction processing systems, decision support systems, knowledge management systems , learning management systems, database management systems, and office information systems.
What part of the nervous system performs information processing and integration?
What part of the nervous system performs information processing and integration? The central nervous system , which consists of the brain and spinal cord, is the integrating and control center of the nervous system.
Which of the following divisions of the nervous system performs processing and integration of information?
The sensory or afferent division of the PNS includes nerves that have a sensory function and carry impulses to the CNS for integration.
What are the two divisions of the autonomic nervous system?
The autonomic nervous system comprises two antagonistic sets of nerves, the sympathetic and parasympathetic nervous systems .
How do neurons communicate in order?
Neurons communicate with each other via electrical events called ‘action potentials’ and chemical neurotransmitters . At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.
What are the three types of neurons?

- Motor neurons. ...
- Interneurons. ...
- Neurons in the brain.
What is a neuron name the three types of neurons and describe the function of each?
There are three major types of neurons: sensory neurons, motor neurons, and interneurons . All three have different functions, but the brain needs all of them to communicate effectively with the rest of the body (and vice versa).
What are the 2 major functions of nervous system?
Basic Functions. The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses) .
How do neurons communicate place in order the sequence of events that occur when a neuron fires?
How do neurons communicate? Place in order the sequence of events that occurs when a neuron fires. ... The presynaptic neuron receives excitatory input, moving it closer to producing an action potential . An action potential is set off and travels through the cell and down the axon.
What are the steps of neural communication?
The entire process of neural communication can be divided into four steps: the reception of the signal by the sense organs, neural transmission to and fro from a neuron to another neuron or muscles or glands , integration of the information from the signal and the action or response to the generated stimulus.

Answer: Neurons have four specialized structures that allow for the sending and receiving of information: the cell body (soma), dendrites, axon and axon terminals (see lowest figure).

Sensory : Connects the brain and spinal cord to your skin and allow you to feel pain and other sensations. Autonomic: Controls involuntary function (e.g., blood pressure, digestion, heart rate). Motor: Connects the brain and spinal cord to muscles to stimulate movement.
What is sympathetic and parasympathetic?
The autonomic nervous system comprises two parts- the sympathetic and parasympathetic nervous system. The sympathetic nervous system activates the fight or flight response during a threat or perceived danger, and the parasympathetic nervous system restores the body to a state of calm.

The second division of the forebrain is the diencephalon , which will give rise to the central structures of the brain, and its cavity will become the third ventricle. From the lateral sides of this section, two cup shaped structures arise, but with no continuity with the inner cavity.

Brain vesicles are the bulge-like features of the early development of the neural tube in vertebrates. Vesicle formation begins shortly after anterior neural tube closure at about embryonic day 9.0 in the mouse and the fourth and fifth gestational week in human development.
