List and describe the function of the various neuronal structures.
(28) 
Answered by Examlex AI CopilotSure, here is a brief overview of the function of various neuronal structures:
1. Cell body (soma): The cell body contains the nucleus and other organelles necessary for the neuron's function. It integrates incoming signals and generates outgoing signals to other neurons.
2. Dendrites: Dendrites are the receiving end of the neuron, where they receive signals from other neurons and transmit them to the cell body.
3. Axon: The axon is the long, slender projection of the neuron that carries outgoing signals to other neurons or to muscles or glands.
4. Myelin sheath: The myelin sheath is a fatty substance that surrounds and insulates the axon, allowing for faster transmission of signals.
5. Axon terminals: The axon terminals are the end of the axon where neurotransmitters are released to communicate with other neurons or target cells.
6. Synapse: The synapse is the junction between two neurons, where signals are transmitted from one neuron to another.
Each of these structures plays a crucial role in the function of neurons and the transmission of signals throughout the nervous system.
Activity of the brain is study outside of the head by this particular technique in which the magnetic fields emitted by changes in brain activity is picked up.
(29) The __________ is responsible for the formation of new memories.
(31) How can the study of the brain have applications for improving human welfare?
(31) An epileptic patient has had her corpus callosum severed.The patient has been asked to draw a three-dimensional form with her left hand.The patient is successful.However,when asked to draw the same object with the right hand,the patient was not able to perform the task successfully.Why not?
(37) Sonia lays in a hospital bed unable to wakeup.Scans of her brain show damage to the ___ which is important for regulating overall level of consciousness/arousal.
(36) This type of disorder is caused by an interruption in the flow of blood to the brain and often contributes to noticeable loss in cognitive functioning.
(32) This particular part of the brain is responsible for regulating behavior that is important for the survival of the organism (e.g. ,fighting,feeding,fleeing,and mating)and "regulating emotions and reactions to stress."
(35) Tom puts his hand on a warm stove burner and senses the heat coming from the stove.The message of warmth travels from his hand to which lobe of the brain?
(34) Joe is walking around a room completely in the dark.He cannot see anything.When he feels the doorknob with his hand,he pulls the door open.What location in the brain most directly enabled him to accomplish what he attempted?
(39) Which of the following is not an in vivo technique for viewing the structures and functions of the brain?
(39) Imagine that you were a doctor in "the old days" (prior to the invention of the various in vivo techniques).First,list a number of cognitive problems that you could study (e.g. ,Korsakoff's syndrome,aphasia,apraxia,case studies like Phineas Gage),then describe how you would use postmortem studies in understanding these various cognitive problems.Include in your discussion the various behaviors of interest.Also,from a scientific standpoint how would you increase the confidence of your findings?
(22) Explain the concept of hemispheric specialization.Include in your discussion a description of the abilities of each hemisphere and the role of the corpus callosum.
(40) These techniques for studying the brain obtain a still image that can help with "revealing the structures of the brain."
(30) Which of the following would most involve the use of the frontal lobe?
(36) This technique has been used for centuries in which researchers document the behaviors of individuals thought to have brain damage and then after the person dies,they examine the brain for lesions.
(39) This technique of studying the living brain is based on examining the recording of the electrical frequencies and intensities of the brain over time.
