Question
Using your textbook, read about the concepts below and compose complete and well written answers to the following questions. Your answers need to be composed in your own words and examples should be used to help illustrate your explanation and demonstrate your understanding of the content Explain how messages are sent from one neuron to another. Explain the pathway the neurotransmitter takes through the neuron parts and why the synapse is important in interpreting the neurotransmitter messages. This must be explained in detail an correctly Explain what the endocrine system's function is. Explain why the pituitary gland is called the "master gland." Explain the function of hormones in the endocrine system. Explain what neuroplasticity is. Be thorough not general. Discuss what a split brain is and how it works. Explain it in your own words so I know you understand it. Go to youtube.com and type in "Split Brain Joe." Watch one of his clips to help you answer this question, using an example from one of the experiments they do on him. Use the example you watch in Joe to explain how the brain has to work independently nowExplanation / Answer
Ans 1) On one end of the neuron are dendrites when stimulated they begin the nerve impulse.It travels through the cell body as an electrical signal through the axon to the terminal branches. Here the terminal branches release neurotransmitter which are chemicals, these travel along the synapse and transmit the information. The synapse is the junction of two nerve cells and it is important because through synapse message is transferred from one neuron to another.Actually the synapse is an empty space between two neuron with no direct connection , the cells send chemical signals across the gap , within each axon terminal as sacs known as vesicles, filled with one of 50 different chemicals called neurotransmitter and each neurotransmitter sends a different type of message to the next neuron , which recognises the neurotransmitterwith specialized receptors on the surface of dendrites.
Ans 2) The endocrine system is made up of glands that produce and secrete hormones , that regulate the activity of cells and organs of the body, and the main function of the endocrine glands is to secrete hormones directly into the blood stream.
Hormones are chemical substances that affect thje activity of the targeted site. Hormones serve as messengers, controlling and coordinating activities throughout the body.
Pitutary gland is called the master gland because it produces hormones that control other glands and many body functions including growth.
ans3) Neuroplasticity is the lasting changes to the brain of an individual throughtout its life.It is the ability of the brain to form and recognise synaptic connections, especially in response to learning or experience or following and injury.Basically it is the changes caused in the brain whenever it is exposed to a new situation either chemically, behaviourally or any other way so that it can retain the experience or the information. It takes place throughout the lifetime of an individual , it can evolve changes to your neurons , vascular cells and glial cells neuroplasticity occurs hand in hand through synaptic pruning which is the brain's way of deleting the neural connections that are no longer necessary or useful and strengthening the necessary ones. It depends on your life experiences and how often the neurons are used.
Ans 4) Split brain is a term to describe when a huge bundle of fibres called as corpus callosum which connects the two parts of the brain is damaged and there is disruption of connection between the two parts of the brain.
In case of Joe due to split brain he is not able to name the objects which is on the left side of a dot on which he is focusing but when he is asked to draw and image from his left hand he can draw that same image without being able to see it, it shows that his two parts of the brain are working differently and independently, i.e. he sees a hammer but when asked to draw an image with his left hand which is controlled by his right brain he draws a saw.,
which shows the independent working of both the parts of the brain.
