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.

Expert Solution & Answer

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.

Regardless of type, all neurons transfer signals between each other or to effectors (muscles or glands) at a synapse. The neuromuscular junction that we talked about with the muscular system is one example of a synapse. The diagram below shows the general features of a synapse Match each term or description with the appropriate letter in the diagram. You may use terms more than once. 1. Synaptic knob in axon terminal of pre-synaptic cell: 2. Synaptic cleft: 3. Neurotransmitter: 4. Dendrite of post-synaptic cell: 5. Cell body of post-synaptic cell: 6. Receptor in plasma membrane of post-synaptic cell: 7. Chemical released by neurons that stimulates or inhibits other neurons, muscles, or glands: 8. Cell that sends the signal: 9. Dendrite of cell that receives the signal: 10. Space between cells that must be crossed by neurotransmitters: 11. Structure that opens, like a "protein door", when neurotransmitters attach to it:

If a neuron is stimulated simultaneously by 2 stimuli at its dendrites (one generates a very large hyperpolarizing potential and the other generates a very small depolarizing potential). What would happen to this neuron? Group of answer choices The summation of these two graded potentials will generate an action potential and this action potential will travel down the axon. Summation of these two graded potentials will cause the membrane potential at the axon hillock to be more negative. These graded potentials will bring the resting membrane potential to 0 mV. These graded potentials with opposite polarity would therefore generate two action potentials and they will travel along this neuron in opposite direction.
