Question 1

The ___________ perspective focuses on social and cultural forces outside the individual.

Accepted Answer

The socio-cultural perspective emphasizes the impact of social and cultural factors on individual behavior and mental processes, focusing on how people are influenced by their social environments and cultural backgrounds.

Question 2

The smallest difference in stimulation that can be reliably detected by an observer when two stimuli are compared, is ____________________

Accepted Answer

The difference threshold, also known as the just noticeable difference (jnd), is the minimum difference in stimulation that a person can detect 50% of the time. It is the smallest change in a sensory stimulus that can be detected.

Question 3

The dimension of auditory experience related to the intensity of a pressure wave, is _________

Accepted Answer

C

Question 4

The change from the resting nerve membrane potential of approximately -70mV to a new +40mV is ___________________________

Accepted Answer

The change from a resting nerve membrane potential of approximately -70mV to a new potential of +40mV is known as an action potential. This process involves the rapid depolarization of the neuron's membrane, allowing for the transmission of nerve impulses.

Question 5

Action potential constitutes the 'firing' of the neuron and is also referred to as the ________________

Accepted Answer

Action potential is the process that occurs when a neuron sends information down an axon, away from the cell body. This is commonly referred to as a nerve impulse, which is the electrical signal that travels along the neuron to communicate with other neurons or muscles.

Question 6

________________ referring to a pair of muscles with the same effects at a joint.

Accepted Answer

Agonistic muscles are those that produce the same effect at a joint, working together to create movement.

Question 7

The process by which an image is kept in focus on the surface of the retina while the object being viewed varies in distance from the eye is referred as the ____________________

Accepted Answer

The answer of The process by which an image is...

Question 8

The portion of the axon that is located immediately outside the boundaries of the soma is __________

Accepted Answer

The axon hillock is the portion of the axon that is located immediately outside the boundaries of the soma, serving as the initial segment of the axon from where action potentials are initiated.

Question 9

__________________ is a portion of the axon after it has subdivided just prior to the synaptic knobs.

Accepted Answer

An axon collateral is a branch of an axon that occurs before the axon terminal, leading to the synaptic knobs.

Question 10

_____________________ is a portion of the dendrite involved in axodendritic synaptic communication.

Accepted Answer

Dendritic spines are small protrusions from a neuron's dendrite that typically receive input from a single synapse of an axon. They are key structures in synaptic communication, particularly in axodendritic synapses, where the axon terminal of one neuron connects to the dendrite of another.

Question 11

The space in the synapse that lies between the presynaptic axon and postsynaptic soma or dendrite, is _______________________

Accepted Answer

The answer of The space in the synapse that lies...

Question 12

The structures in the synaptic knobs that store neurotransmitters prior to the release of neurotransmitters into the synaptic cleft, is _________________________

Accepted Answer

Synaptic vesicles are small sacs within the synaptic knob that store neurotransmitters before they are released into the synaptic cleft to transmit a nerve impulse to another neuron.

Question 13

__________________ is a fat and protein substance surrounding some axons in the nervous system, arranged as a series of segments along the length of the axon.

Accepted Answer

Myelin sheath is the correct answer because it is a fatty substance that surrounds axons in the nervous system, providing insulation and increasing the speed of electrical impulses.
