Question

question 3 (2 points) according to the all - or - nothing principle, which of the following would happen if the size of the electrical charge in a neural impulse was twice the size needed for the electrical impulse? the neuron would go back to its resting potential without transmitting any information. the intensity of the impulse would not be affected. the intensity of the impulse would be twice as strong. the axon of the neuron will develop a new branch. question 4 (2 points) the anterior (front) part of the pituitary gland is known as the master gland because almost all of its hormones direct the activity of target glands elsewhere in the body. its hormones are released in the cerebral fluid, not in the bloodstream. it is a dual - purpose gland that performs both digestive and endocrine functions. it controls the hypothalamus and its functions.

Explanation:

For Question 3, the all - or - nothing principle states that a neuron either fires completely or does not fire at all. The intensity of an impulse is not affected by the strength of the electrical charge above the threshold. For Question 4, the anterior pituitary is called the master gland because its hormones regulate the activity of other endocrine glands in the body.

Answer:

Question 3: The intensity of the impulse would not be affected.
Question 4: almost all of its hormones direct the activity of target glands elsewhere in the body.
