Question 3

During depolarization, the inside of the neuron's membrane becomes less negative.

Accepted Answer

During depolarization, the membrane potential becomes less negative as positively charged ions, such as sodium, flow into the neuron.

D) Secretory region
E) Secretory zone
-Plasma membrane exhibits voltage-gated Na⁺ and K⁺ channels.

Question 5

Match the following:
A) Reverberating circuit
B) Diverging circuit
C) Converging circuit
D) Parallel after-discharge circuit
-Involved in control of rhythmic activities such as breathing.

Accepted Answer

The circuit involved in control of rhythmic activities such as breathing is a reverberating circuit, which is a type of circuit that continues to fire even after the initial stimulus has stopped. This allows for the sustained control of rhythmic activities like breathing.

Question 6

Myelination of the nerve fibers in the central nervous system is the job of the oligodendrocyte.

Accepted Answer

Oligodendrocytes are responsible for myelinating nerve fibers in the central nervous system. In contrast, Schwann cells myelinate nerve fibers in the peripheral nervous system.

Question 7

Reflexes are rapid, automatic responses to stimuli.

Accepted Answer

Reflexes are indeed rapid and automatic responses to stimuli, such as pulling your hand away from a hot stove or blinking when something suddenly comes towards your eyes.

Question 8

Match the following:
A) Reverberating circuit
B) Diverging circuit
C) Converging circuit
D) Parallel after-discharge circuit
-Different types of sensory input can have the same ultimate effect.

Accepted Answer

A converging circuit is when multiple sources of sensory input converge onto a single neuron. This can result in the same ultimate effect, such as the sensation of pain from different types of stimuli (e.g. heat, pressure, chemicals).

Question 9

Match the following:
A) Reverberating circuit
B) Diverging circuit
C) Converging circuit
D) Parallel after-discharge circuit
-One incoming fiber triggers responses in ever-increasing numbers farther and farther along the circuit.

Accepted Answer

The answer of Match the following:
A) Reverberating circuit
B) Diverging circuit
C)...

Question 10

The all-or-none phenomenon as applied to nerve conduction states that the whole nerve cell must be stimulated for conduction to take place.

Accepted Answer

The all-or-none phenomenon refers to the principle that once a nerve impulse is initiated, it will travel along the neuron all the way to the end without decreasing in strength, but it does not require the whole nerve cell to be stimulated for conduction to take place; rather, it requires reaching a certain threshold of stimulation at the trigger zone.

Question 11

Match the following:
A) Trigger zone
B) Receptive region
C) Conducting region
D) Secretory region
E) Secretory zone
-Plasma membrane exhibits chemically gated ion channels.

A) Trigger zone
B) Receptive region
C)...

Accepted Answer

The answer of Match the following:
A) Trigger zone
B) Receptive region
C)...

Question 13

Match the following:
A) Trigger zone
B) Receptive region
C) Conducting region
D) Secretory region
E) Secretory zone
-Plasma membrane exhibits voltage-gated Ca²⁺ channels.

Accepted Answer

The answer of Match the following:
A) Trigger zone
B) Receptive region
C)...

Question 14

Match the following:
A) Trigger zone
B) Receptive region
C) Conducting region
D) Secretory region
E) Secretory zone
-Area where nerve impulse is generated.

Accepted Answer

The answer of Match the following:
A) Trigger zone
B) Receptive region
C)...

Question 15

Match the following:
A) Reverberating circuit
B) Diverging circuit
C) Converging circuit
D) Parallel after-discharge circuit
-Involved in activating fibers of a skeletal muscle such as the biceps muscle.

Accepted Answer

Diverging circuits are used in the nervous system to spread a signal from one neuron to multiple neurons, which is necessary for activating multiple muscle fibers in a skeletal muscle like the biceps.

Question 16

Cell bodies of sensory neurons may be located in ganglia lying outside the central nervous system.

Accepted Answer

This is true. Sensory neurons can have cell bodies in ganglia located outside of the central nervous system, such as the dorsal root ganglia of the spinal nerves.

Question 17

Neurons in the CNS are organized into functional groups.

Accepted Answer

Neurons in the CNS, particularly in the brain and spinal cord, are organized into functional groups such as sensory, motor, and interneurons for efficient processing of information and signal transmission.

Question 18

Match the following:
A) Spatial summation
B) Threshold stimulus
C) Subthreshold stimulus
D) Temporal summation
-An insufficient stimulus.

Accepted Answer

The answer of Match the following:
A) Spatial summation
B) Threshold stimulus
C)...

Question 19

Efferent nerve fibers may be described as motor nerve fibers.

Accepted Answer

Efferent nerve fibers carry signals away from the central nervous system to muscles and glands, and are therefore commonly referred to as motor nerve fibers.

Question 20

Match the following:
A) Spatial summation
B) Threshold stimulus
C) Subthreshold stimulus
D) Temporal summation
-Any stimulus below this intensity will result in no response in a neuron.

A) Spatial summation
B) Threshold stimulus
C)...
