Chapter 12, Problem 1DYKB
Summary Introduction

Introduction:

Synapses are the connecting zone or the junctional region between two nerve cells. These regions help in the conduction of the nerve impulses from one neuron to the axon. A synaptic region is generally located between the axon of one neuron and the dendrites of the subsequent one.

Answer to Problem 1DYKB

Correct answer:

The correct answer is option (a) they release neurotransmitters into the synaptic cleft.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) the axon terminals (of nerve cells) have round knob-like structures called synaptic knobs. These contain secretory vesicles (synaptic vesicles) that release NTs into the synaptic cleft. These NTs are needed for the transmission of nerve impulses from one neuron to another.

Explanation for incorrect answer:

Option (b) The synaptic knobs possess synaptic vesicles. These vesicles transmit the NTs into the subsequent neuron and not back to the synaptic knob. Hence, this is an incorrect option.

Option (c) They conduct graded potentials (action potentials) to the next neuron. Hence, this is an incorrect option.

Option (d) They are located in the axon terminals of a neuron. They conduct nerve impulses to the dendrites of the next one. Hence, this is an incorrect option.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
