Nervous System and Terminal Buttons
1. What are the three functions of a neuron? -Receive information from other cells -Process the information -and transmit it to the rest of the body
2. What are the main parts of a neuron? Please define axon, dendrites, soma, terminal buttons and synapse. The main parts of a neuron are: Axon, Dendrites, terminal buttons and myelin sheath.
Axon: The axon receives and carries messages by the dendrites in other neurons. It is the longer part of the rest of the neuron and it is covered with a protective coat of fat called myelin sheath. The axon finish with the terminal buttons.
Dendrites: the dendrites receive messages from other neurons.
Soma: The soma is where the signals from the dendrites are joined and passed on. It serves to maintain the cell and keep the neuron functional.
Terminal Buttons: are small bulges at the end of the axon and they send messages to other neurons.
Synapse: It is the space between two neurons where the axon communicates with messages from other neurons (Dendrites) by using chemical messages.
3. Why is the function of our brain and our behavior so complex? List a minimum of least three reasons. The function of our brain and our behavior is so complex, because the brain is made up of different regions and parts, each one with a different function. It maintains a proper metabolism, respiration and temperature. It also helps with the activities in our lives such as remembering and making decisions and learning.
4. Give one example of a neurotransmitter? What is the purpose of this specific neurotransmitter? One example is acetylcholine. It is found in the nervous system and it sends messages relating to our skeletal muscles. Also, it helps with the capacity of memory capabilities.
5. Who are neuroscientists? They study the brain and behavior;

    3. The axon terminal is the nerve ending. The nodes speed up the message. The myelin sheath is an insulating membrane. The axon carries impulses away from the cell body. The cell body is the largest part of a typical neuron. The dendrites carry impulses from the environment or from other neurons toward the cell body. The nucleus is the control center of the cell.…

    There are five major parts of a neuron, the axon, soma, dendrites, the axon hillock and the terminal buttons. The axon transmits the neural signal. The stoma is where signals from the dendrites are joined and passed on. It serves to maintain the cell and keep the neuron functional. The dendrites help increase the surface area of the cell body. They receive info from other neurons and transmit electrical stimulation to the stoma. The axon hillock controls the firing of the neuron. The terminal buttons are responsible for sending the signal on to other neurons.…

    The nerve cell body contains the nucleus, rough ER (Nissl bodies), and cytoplasm. It is the major biosynthetic center and the main body for the outgrowth of neuronal processes. Axons and Dendrites are both arm-like extensions from the cell body. Dendrites are short and extremely branched processes that function as the input regions of neurons. Axons are long branched processes that contain end bulbs, these bulbs secrete neurotransmitters, so axons function as the output.…

    Why Are Neurons Important

    Neurons are the essential tools we use for every sense that we have, from touch and sound, to critical thinking processes. While true that some neurons vary in many different kinds of shapes, most contain the same basic structure. A neuron consists of three parts: a cell body, dendrites, and an axon. The cell body contains the nucleus and the dendrites receive input from other neurons through the use of their widely branching structures. Dendrite comes from a Greek word meaning "tree". The axon transmits information to other cells. Differing from the dendrites, the axon is a long, thin fiber with branches at its tip.…
