It has two extensions from the central cell body. Multipolar Unipolar Pseudounipolar Ques 2 / 2 pts tion 7 True or false: Neurons do not physically touch one another. True Correct! 5/12/2020 Module 1 Exam- Requires Respondus LockDown Browser: Essential Human Anatomy and Physiology II with Lab- Correll https://nursingabc.instructure.com/courses/184/quizzes/7946?module_item_id=21286 5/16 Neurons do not physically touch. They are separated by synapses. False Ques Not yet graded / 4 pts tion 8 Your Answer: Describe the function and release of neurotransmitters. Neurotransmitters are chemicals that are stored in the axon terminal vesicles. When neurotransmitters are released they carry the nerve impulse to one neuron to the next. Neurotransmitters are chemicals stored inside secretory vesicles (axon terminal vesicles) at the end of the axon terminals. When neurotransmitters are released by the axon terminal vesicles, they carry the transmission of the nerve impulse from one neuron to another.

Within the central nervous system Within the peripheral nervous system Ques 2 / 2 pts tion 10 A postsynaptic neuron would be found: Before the synapse After the synapse Correct! Inside the synapse Only in the central nervous system Ques Not yet graded / 3 pts tion 11 Your Answer: What is the location and function of Satellite cells? Satellite cells surround the body of peripheral neurons. They regulate the cell body environment. Location: Peripheral nervous system (PNS) Function: Regulation of environment of neuron cell bodies 5/12/2020 Module 1 Exam- Requires Respondus LockDown Browser: Essential Human Anatomy and Physiology II with Lab- Correll https://nursingabc.instructure.com/courses/184/quizzes/7946?module_item_id=21286 7/16 Ques Not yet graded / 3 pts tion 12 Your Answer: A patient’s spinal cord was severed in a car accident. Would the patient be expected to regrow axons in their spinal cord? Why or why not? Yes it would be expected to regrow axons in the spinal cord. If a peripheral nerve axon is severed, the schwann cells grow ahead of the axon which allows the path for the axon to follow as it grows. No; Only peripheral system axons are capable of regeneration. The spinal cord is in the central nervous system. Ques Not yet graded / 10 pts tion 13 Name and describe what is occurring in the neuron cell membrane in section 4 of the diagram. Include the charge of the membrane during this phase. 5/12/2020 Module 1 Exam- Requires Respondus LockDown Browser: Essential Human Anatomy and Physiology II with Lab- Correll https://nursingabc.instructure.com/courses/184/quizzes/7946?module_item_id=21286 8/16 Your Answer: Afterpolarization. During afterpolaraization, voltage drops below -70mV and then returns to -70mV when the resting state begins again. Afterpolarization (Hyperpolarization) Potassium gates are slow to close and there is an undershoot of the potential.
