Question

11. Which of the following statements are true? (1) The frequency of
impulses and number of activated sensory neurons encodes differ-
ences in stimuli intensity. (2) Larger-diameter axons conduct nerve
impulses faster than smaller-diameter ones. (3) Continuous conduc-
tion is faster than saltatory conduction. (4) The presence or absence
of a myelin sheath is an important factor that determines the speed
of nerve impulse propagation. (5) Action potentials are localized,
but graded potentials are propagated.
(a) 1. 3. and 5
(b) 3 and 4
(c) 2, 4, and 5
(d) 2 and 4
(e) 1, 2, and 4​

Answer 1

Answer:

2,4, and 5

Explanation:

2) Larger-diameter axons conduct nerve

impulses faster than smaller-diameter ones

(4) The presence or absence

of a myelin sheath is an important factor that determines the speed

of nerve impulse propagation. (5) Action potentials are localized,

but graded potentials are propagated.
