Neurology and Neurophysiology
Questions 1through 5 refer to the diagram below: Assume the threshold for producing an action potential is -15 mv. 1. Response A shows:
Choices: (1) hyperpolarization, (2) depolarization,
(3) a graded potential, (4) EPSP, (5) IPSP.
Answers: (A) 1, 3, and 5, (B) 2, 3, and 4, (C) 1 and 4 only, (D) 2 and 5 only. 2. Response C is caused by only a single input to this neuron . Response C illustrates: (A) temporal summation,
(B) spatial summation. 3. In this example an action potential _____ be produced.
(A) would, (B) would not. 4. If A and C occurred simultaneously, it would result in:
(A) temporal summation to produce threshold depolarization,
(B) spatial summation to produce threshold depolarization,
(C) no threshold depolarization produced.
5. The response seen in A is due to:
(A) Opening of chemically-gated Na+ channels
(B) Opening of chemically-gated K+ channels
(C) Opening of voltage-gated Na+ channels
(D) Opening of voltage-gated K+ channels
6 through 11 Matching: Answers may be used more than once or not at all.
(A) fasciculus gracilis and cuneatus (considered as a single tract), (B) spinocerebellar tract,
(C) spinothalamic tract, (D) all of the above, (E) A and B only, (F) A and C only.
6. First order neuron is a unipolar neuron
