Not yet graded / 2.5 pts Question 3 sympathetic nervous system Sympathetic 5/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 The neuron pictured, below, is best described as: 2 / 2 pts Question 6 6/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 Correct! Bipolar It has two extensions from the central cell body. Multipolar Unipolar Pseudounipolar 7/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 True or false: Neurons do not physically touch one another. Correct! True 2 / 2 pts Question 7 10/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 Correct! Only in the central nervous system Inside the synapse After the synapse Before the synapse A postsynaptic neuron would be found: 2 / 2 pts Question 10 Correct! From the peripheral to the central nervous system Within the central nervous system Within the peripheral nervous system 11/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 Location: Peripheral nervous system (PNS) Function: Regulation of environment of neuron cell bodies Your Answer: Satellite cells surround the body of peripheral neurons. They regulate the cell body environment. What is the location and function of Satellite cells? Not yet graded / 3 pts Question 11 12/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 No; Only peripheral system axons are capable of regeneration. The spinal cord is in the central nervous system. Your Answer: 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. 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? Not yet graded / 3 pts Question 12 15/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 At rest, a neuron plasma membrane is: Correct! -70 mV 3 / 3 pts Question 14 16/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 Correct! (False, the effect of the pump is a negative charge inside the membrane, positive on the outside.) The overall effect is a negative charge on the outside of the membrane. It must remain in constant operation to maintain the resting state. For every three sodium ions pumped out, two potassium ions are pumped in. It maintains the resting phase of an axon. Which of the following is false concerning the sodium-potassium pump? 3 / 3 pts Question 15 (polarized) +40 mV Hyperpolarized Depolarized 17/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 True or false: A sensory neuron is signaling the body of a light touch. This means that the strength of the action potential is weaker than usual. Explain your reasoning. Not yet graded / 4 pts Question 16 20/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 Dopamine Your Answer: Dopamine What neurotransmitter helps regulate emotional responses and muscle tone? Not yet graded / 2.5 pts Question 19 Neurotransmitters are released from the axon terminal vesicles then omitted across a synapse to the dendrite of another neuron. There is a minute fluid-filled space, called a synapse, between the axon terminal of the sending neuron and the dendrite of the receiving neuron. When a nerve impulse reaches the end of an axon, neurotransmitters are released into the synapse. These bind with a receptor on the next neuron, opening Na+ gates in the receiving dendrite which causes depolarization and the impulse is carried. 21/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 True or False: Action potentials travel in one direction within the same neuron. Correct! True 2.5 / 2.5 pts Question 20 22/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 Correct! False True True or False: Reflexes occur slower than a conscious decision to move from the brain. 3 / 3 pts Question 21 (only one direction in the same neuron) False 25/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 What is true about the stretch reflex? Stretch reflexes help to increase the stretch on a muscle. The patellar reflex tests the stretch reflex of the patella. Correct! The muscle spindle detects stretch within the muscle. The effect of the motor signal is to relax a muscle. 3 / 3 pts Question 25 26/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 Correct! F. B&C E. A&D D. The effect of the reflex is to create a co-contraction of two muscles C. It involves inhibitory interneurons. B. It involves excitatory interneurons. A. It does not involve interneurons. What is true about the flexor withdrawal reflex? 4 / 4 pts Question 26 Question 27 Not yet graded / 10 pts Answer the following essay questions: Your doctor taps on your patellar tendon. List out the steps, in detail, of the nervous pathway of the reflex he is testing. Include any sensory organs involved and the action of the reflex. Your Answer: 27/16 BIOD 152 AP2 Module 1 Exam Study Guide Latest Updated Comprehensive Study Guide Version 2024/2025 The sensory neuron detects the tap on the patellar tendon, then sends signal through the ganglion in the dorsal root to the spinal cord. Then the sensory neruon synapses in the gray matter of the spinal cord onto a motor neuron in the anterior horn. The motor neuron sends signal through the ventral root and synapses back on the patellar tendon.
