Question:

Which neurons transmit information from the central nervous system to muscles and glands?
(a) Sensory neurons
(b) Interneurons
(c) Motor neutrons
(d) Bipolar neurons

Answers

1) A - 4
A type of neuron that sends information away from the central nervous system to muscles or glands - Efferent neuron. The main characteristic for this type of neuron is that its axon conducts motor impulses outwards right from the brain (possibly spinal) cord.
2)  B-7

A type of neuron that sends information from the sensory receptors toward the central nervous system is afferent neuron. This type of neuron is also known as sensory neurons. Its function is to convert a particular stimulus, through the receptors, in other words - to process the sensory transduction.
3) C-1

Long fibers that carry signals away from the cell body are called axon. The main function of axon is to conduct electrical impulses outwards from the neuron's cell body. Keep in mind that each nerve cell has one axon, and its dimensions can be over a foot long. As a result of transmitting signals from axon nerve, nerve cells communicate with each other.
4) D-5

The fatty material surrounding some axons is called myelin sheath. Myelin sheath plays one of the most important parts in functioning of the nervous system. It is a white fatty layer that is placed around the axon of some nerve cells and its function is to form an electrically insulating layer.

5) E-2

Short, highly branched fibers that carry signals toward the cell body are called dendrites. They are projections of a neuron, to be more exact they are extensions of the cytoplasm of a neuron. They are needed to propagate the electrochemical stimulation which the cell body received from some neural cells.

6) F-8

Gaps in the myelin sheath are called Node of Ranvier. They are simply known as myelin-sheath gaps, and they are spaces between the myelin coating on the neuron's axon. What about their function: they serve to support the rapid conduction of nerve impulses.

7) G-3

The space between two cells is called synaptic cleft. Sometimes it is called synaptic gap because it is actually a minute gap between presynaptic cell and postsynaptic cell that takes place during a chemical synapse.  When a synapse is formed, nerve impulse is transmitted.

8) H-10

A type of neuron that sends information between sensory and motor neurons is called interneuron. Interneuron is responsible for communication between sensory or motor neurons and the CNS. The center of their functioning is placed in reflexes (neuronal oscillations).

9)  I-9

The reversal of the electrical potential in the plasma membrane of a neuron is called action potential. It is a process of a short-term change that occurs in the electrical potential on the surface of a cell, as a response to stimulation. Eventually it leads to the transmission of a nerve impulse that moves across the cell membrane.

10) J-6
A type of chemical released from the tip of an axon into the synaptic cleft when a nerve impulse arrives is neurotransmitter. It is also known as chemical messengers, that are responsible for enabling neurotransmission. Their main function is to transfer signals across a chemical synapse from one nerve cell to another one.

Neurons are the cells that is involved in sending and receiving signals.

Further Explanation:

The nervous system consists of neurons which are involved in transmitting the information to other nerve cells, gland cells and muscle.

Neurons consists of the following:

1. Cell body: It contains the nucleus and cytoplasm.

2. Axons: It extends from cell body and contains smaller branches.

3. Dendrites: It extends from the cell body and takes message or the signal from other neurons.

4. Synapsis: Point of communication between two neurons.

5. Synaptic cleft: It is the space between two cells.

6. Efferent neuron: The neurons which sends the information away from the central nervous system to glands.

7. Myelin sheath: It is the fatty materials that surrounds some axons.

8. Neurotransmitter: It is the type of chemical that is released from the tip of axons to the synaptic cleft whenever the nerve impulses arrives.

9. Afferent neuron: This type of neurons sends the information from the sensory receptors to the central nervous system.

10. Nodes of Ranvier: It is the space between the myelin sheath.

11. Action potential: It is the reversal of electrical potential present in the plasma membrane of the neuron.

12. Interneuron: This is the type of neuron that sends the information between the sensory neurons and the motor neurons.

Neurons, nervous system, nerve cells, gland cells , muscle, cell body, Axons, dendrites, synapsis, synaptic cleft, efferent neuron, myelin sheath, neurotransmitter, afferent neuron, nodes of Ranvier, action potential, interneuron.

The correct answers are:

1. Axon                    ⇔ (C)
2. Dendrite              ⇔ (E)
3. Synaptic cleft      ⇔ (G) 
4. Efferent neuron   ⇔ (A) 
5. Myelin sheath     ⇔ (D) 
6. Neurotransmitter ⇔ (J)
7. Afferent neuron   ⇔ (B)
8. Node of Ranvier  ⇔ (F)
9. Action potential    ⇔ (I)
10. Interneuron        ⇔ (H)

Explanations:
(1) In a neuron, Axon is the long thread-like part (fiber) of a nerve cell along which impulses are conducted/passed from the cell body to other cells (neurons). Therefore, from the options given, the best suited sentence is "Long fibers that carry signals away from the cell body." (C)
Hence, 1. Axon ⇔ (C) Long fibers that carry signals away from the cell body

(2) In a neuron, Dendrite is a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body. Therefore, from the options given, the best suited sentence is "Short, highly branched fibers that carry signals toward the cell body." (E)
Hence, 2. Dendrite ⇔ (E) Short, highly branched fibers that carry signals toward the cell body.

(3) Synaptic cleft is the space between neurons at a nerve synapse across which a nerve impulse is transmitted by a neurotransmitter. It is also called synaptic gap. Therefore, from the options given, the best suited sentence is "The space between two cells." (G)
Hence, 3. Synaptic cleft ⇔ (G) The space between two cells.

(4) Efferent neuron is a neuron that conducts impulses outwards from the brain or the spinal cord to the muscles or organs throughout the body. Therefore, from the options given, the best suited sentence is "A type of neuron that sends information away from the central nervous system to muscles or glands." (A)
Hence, 4. Efferent neuron ⇔ (A) A type of neuron that sends information away from the central nervous system to muscles or glands.

(5) Myelin sheath is the fatty, insulating covering that surrounds an axon with multiple spiral layers of myelin. The main purpose of a myelin sheath is to increase the speed at which impulses propagate along the myelinated fiber. Therefore, from the options given, the best suited sentence is "The fatty material surrounding some axons." (D)
Hence, 5. Myelin sheath ⇔ (D) The fatty material surrounding some axons.

(6) Neurotransmitter is a chemical substance which is released at the end of a nerve fibre by the arrival of a nerve impulse and, by diffusing across the synapse or junction, effects the transfer of the impulse to another nerve fibre, a muscle fibre, or some other structure. Therefore, from the options given, the best suited sentence is "A type of chemical released from the tip of an axon into the synaptic cleft when a nerve impulse arrives." (J)
Hence, 6. Neurotransmitter ⇔ (J) A type of chemical released from the tip of an axon into the synaptic cleft when a nerve impulse arrives.

(7) Afferent neuron is a neuron conducting impulses inwards to the brain or spinal cord from muscles or organs throughout the body. Therefore, from the options given, the best suited sentence is "A type of neuron that sends information from the sensory receptors toward the central nervous system." (B)
Hence, 7. Afferent neuron ⇔ (B) A type of neuron that sends information from the sensory receptors toward the central nervous system.

(8) Node of Ranvier, in a neuron, is a gap in the myelin sheath of a nerve, between adjacent Schwann cells. Therefore, from the options given, the best suited sentence is "Gaps in the myelin sheath." (F)
Hence, 8. Node of Ranvier ⇔ (F) Gaps in the myelin sheath.

(9) Action potential is the change in electrical potential associated with the passage of an impulse along the membrane of a nerve cell or a muscle cell. Therefore, from the options given, the best suited sentence is "The reversal of the electrical potential in the plasma membrane of a neuron." (I)
Hence, 9. Action potential ⇔ (I) The reversal of the electrical potential in the plasma membrane of a neuron.

(10) Interneuron is neuron that transmits impulses between sensory neurons and the motor neurons. It, itself, is neither a motor neuron nor a sensory neuron. Therefore, from the options given, the best suited sentence is "A type of neuron that sends information between sensory and motor neurons." (H)
Hence, 10. Interneuron ⇔ (H) A type of neuron that sends information between sensory and motor neurons.
