one million

five-hundred thousand

one-hundred billion

QUESTION 2

Nerve impulses in this neuron usually travel in the direction marked by:

a

b

either a or b, depending upon whether the muscle end is active or the other end is active

a and c simultaneously

QUESTION 3

There is a distinct physiological pattern that emerges when people are exposed to strong and prolonged stress. Hans Selye labeled this response pattern the

general adaptation syndrome (GAS).

two-factor theory of stress.

chronic stress response (CSR).

transactional stress response (TSR).

QUESTION 4

Which of the following represents Edward L. Thorndike’s major contribution to the field of psychology?

the design of systematic, objective, well-documented research on animal learning and behavior

the development of evidence that species such as chimpanzees use insight to solve complex problems

the demonstration that rats and other species can behave adaptively using cognitive maps

the discovery that reflexive responses can be affected by environmental contingencie

one billion

one million

five-hundred thousand

one-hundred billion

Explanation / Answer

Answer-1) One hundred billion

Explanation - The nervous system of human is composed of 2 basic cell types which are 1) glial cells (also known as glia) 2) Neurons.

Glial cells provide help to neurons to line up closely with each other and allow neuronal communication, transport nutrients, insulation to neurons and mediate immune responses.

Neurons however, is an interconnected information processors which is essential for all of the tasks of the nervous system. They are the central building blocks of the nervous system estimated as high as 75-100 billion in count.

Answer-2) Please provide the image/picture/diagram

Answer-3) Genreal adaptation syndrome (GAS)

Explanation-

In the year 1936, scientist Hans Selye also called as the father of stress research introduced the General Adaptation Syndrome model. His theory states that the stress is a major cause of disease due to long term chemical changes caused by chronic stress.

Answer-4) The discovery that reflexive responses can be affected by environmental contingencie.

Explanation- Thorndike primarily used cats in the puzzle boxes. When the cats were put into the cages they did not know how to escape.Eventually, the cats stepped on the switch on the floor by chance, and the door would open.To see if the cats too could learn through observation, he had observed other animals escaping from the box.
