CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...

What are the two types of cells in the nervous system? Ans: Neuron and glia Capable of transmitting electrical signals - these electrical changes are made possible by ions Ans: Neurons Form insulating and metabolic resource for neurons - support to the neurons - outnumber them 10:1 Ans: Glial Cells Branchlike parts of a neuron that are specialized to receive information. Ans: Dendrites cell body of a neuron Ans: Soma the cone-shaped area on the cell body from which the axon origin...

EXPH 386 Exam 3 Latest Update Graded A+ neuromuscular system coordination and integration of the muscles of the body together with the nerves that supply them cell body (soma) -peripheral dictates the critical firing rate of the action potential. Larger cell bodies are associated with higher critical firing rates. Also contain the structures involved in replication and transmission of the genetic code Dendrites short neural branches that *receive* impulses through numerous connect...

BIOL 1201 FINAL SIEBENALLER LSU TEST QUESTIONS WITH CORRECT DETAILED ANSWERS NEURONS: Support Cells: Schwann Cells - Answer-- In PNS (nerves outside of the brain- spinal column) - Form myelin sheath that insulates that axon of vertebrates in the PNS NEURONS: Nodes of Ranvier - Answer-- Non-insulated regions along the axons - Salutatory conduction of the nerve impulses What is the function of the sodium-potassium pump? - Answer-To maintain regulated levels of concentrations of Na & K ...

Final Exam Review - PSYC 375 Questions With 100% Correct Answers The term saltatory conduction refers to the fact that - answeraction potentials occur only at the nodes of Ranvier of axons. If you inserted a micropipette into a neuron without harming the cell, and pumped in a small quantity of calcium ions, each of which carried two positive charges, how would this affect the membrane potential? - answerThe membrane potential would become depolarized relative to the resting potential. Al...

Filtered wastes from the glomerulus will move in the following order: Bowman's capsule-proximal tubule-distal tubule-loop of henle- collecting duct. (True/False) - False. Bowman's capsule- proximal tubule- loop of henle- distal tubule- collecting duct. Specificity of hormone action in the target cells is determined by receptors. (True/False) - True. The area of nerve axon not wrapped by myelin sheath is called the nodes of Rnavier where action potential is insulated. (True/False) - False. My...

intercellular ground substance is composed of - correct answer protein carbohydrate complexes What RNA virus is associated with the common cold? - correct answer Rhinovirus Which generalization is correct about proximal contact areas? - correct answer Anterior teeth have contact areas that are generally centered faciolingually Slightly damaged tissues completely returns to its normal structure and function in which healing process? - correct answer Regeneration Pain sensation...

T or F: Cardiac muscle contraction is considered to be a voluntary movement. - Answer-False T or F: In the gastrointestinal tract, smooth muscle is the major muscle type. - Answer-True T or F: In our body, approximately 8 liters of intestinal juices are secreted into the GI tract daily, but only 100 ml of water is secreted into the feces. - Answer-True What is the normal movement of blood through the heart? - Answer-Right atrium- right ventricle- lung- left atrium- left ventricle Nor...
