The nervous system is the body’s largest and most complex organ. It includes the brain and spinal cord, which are the main parts of the body that control movement and speech. The nervous system also includes the muscles that help us move our body and the chemicals that help us feel the effects of the environment.
What is the basic building block of the nervous system quizlet?
The nervous system quizlet is a quiz that asks students about the basic structure of the nervous system.
What are the basic building blocks of the brain?
The basic building blocks of the brain are cells, which are responsible for making and sending messages to each other, and neurotransmitters, which are chemicals that allow neurons to communicate.
Which of the following is an antagonist that blocks the actions of a particular neurotransmitter?
A. A virusB. A nerve agentC. A pharmaceuticalC. A pharmaceutical
What are the two main divisions of the peripheral nervous system how do these systems relate to the three types of muscle?
The peripheral nervous system includes the brain, spinal cord, and nerves that travel directly to the muscles. It helps to control the muscles in the body and helps to communicate with the brain.
What are the building blocks of the brain quizlet?
The brain quizlet is made up of five questions that ask about different aspects of the brain.
What is the basic unit of the nervous system and why is it considered so?
The nervous system is the largest and most complex organ in the body and it is responsible for making and sending signals to the rest of the body. The nervous system is made up of cells, which are connected by axons. Axons are long, thin tubes that carry information between cells. The nervous system is also made up of nerves, which are the cells that carry the signals from the brain to the rest of the body.
Does your brain change throughout our lives?
There is no single answer to this question as the answer may depend on a person’s individual life experiences and brain chemistry. However, some scientists believe that the brain does change throughout our lives, with the most significant changes occurring in the early years of life.
What is a synapse?
A synapse is the junction of two cells in the brain and is responsible for sending impulses between the two cells.
What is spiral cord?
Spiral cord is a type of cord made from a spiral of different colors. It is used to hang items in a room or to tie together pieces of furniture.
What are the four main divisions of the peripheral nervous system?
The peripheral nervous system includes the autonomic nervous system, the hypothalamic-pituitary-adrenal system, the cerebellum, and the spinal cord.
Which neurons House neurotransmitters?
The neurons that transmit neurotransmitters are called postsynaptic cells.
How would blocking the reuptake of a particular neurotransmitter cause it to continue to stimulate the next neuron?
When a neuron is stimulated by a neurotransmitter, it releases more of that neurotransmitter. This increases the number of neurons that are stimulated and causes them to fire more often. This keeps the neuron active and stimulated.
Which of the following are the cellular building blocks of the brain?
A neuron is a small, single-celled structure in the brain that transmits electrical signals. Neurons are made up of a cell body and a membrane.
Which of the following best summarizes the main function s of your nervous system?
Nervous system functions include the ability to perceive, respond to, and move objects.
What are the 5 parts of the nervous system?
The nervous system is made up of the brain, spinal cord, heart, lungs, and other organs. It helps you feel safe and comfortable in your own body, and helps you think, feel, and act.
Which of the following is not part of the central nervous system?
A. BrainB. spinal cordC. heartC. heart
What is the basic structure and function of a neuron?
A neuron is a cell in the body that sends and receives signals. Neurons are important in the brain because they send and receive messages to and from other cells in the body.
What are the 7 parts of the nervous system?
The nervous system is made up of the brain, spinal cord, heart, lungs, and blood vessels. It helps us feel safe and comfortable in our own bodies, and helps us process information.
What inhibits cell firing in the central nervous system and excites cell firing in the heart muscles?
A lack of ATP.
What 3 parts make up the nervous system?
The nervous system is made up of the brain and spinal cord.
What are the building blocks of communication within the nervous system?
One of the building blocks of communication within the nervous system is nerve impulses. Nerve impulses are the basic unit of information in the nervous system.
What are the building blocks of neurotransmitters?
The building blocks of neurotransmitters are serotonin, dopamine, and glutamate.
Which neurotransmitter inhibits CNS activity in order to calm a person down during stressful situations *?
cortisol
What includes PNS?
PNS stands for Personal Notifications Service. It is a service that allows users to receive notifications about changes to their account, such as new balance, new transactions, or new messages.
What is the main function of nervous system?
Nervous system is responsible for the body’s ability to feel fear, feel pain, think, and act.
Is Neuron a connective tissue?
Neuron is a connective tissue.
Which of the following are the three basic types of neurons?
A neuron is a type of cell that can create electricity and send signals through the nervous system.
Why are neurons considered as building blocks of the nervous system?
Neurons are considered as building blocks of the nervous system because they are responsible for sending and receiving signals between cells in the brain.
What is the purpose of dendrites?
Dendrites are a type of cell membrane that support the growth and development of new cells in the brain.
What is difference between CNS and PNS?
The main difference between CNS and PNS is that CNS is responsible for the body’s overall control and function, while PNS is responsible for the body’s response to external stimuli.
