4. For a receiving tennis player what is the path from stimulus to resnonse?​

Answer 1

ANSWER

ANSWERThe hypothalamus is responsible for maintaining the internal balance of the body called homoeostasis. This activity of the hypothalamus is performed by stimulating or inhibiting many of body processes such as-

This help restore blood volume and pressure.

At lower blood pressure the degree of stretch in nerves is lower. When the cardiovascular center present in the medulla oblongata receives this signal it activates a reflex that maintains homeostasis,

Answer 2

Answer:

first question

The hypothalamus is responsible for maintaining the internal balance of the body called homoeostasis. This activity of the hypothalamus is performed by stimulating or inhibiting many of body processes such as-

1) Body temperature- Sweating in heat and shivering in cold.

2) Drive to eat and the expenditure of energy in response to nutritional signals.

3) Fluid balance- ADH signals its target cells in the kidneys to reabsorb more water, thus preventing the loss of excess fluid in the urine. This help restore blood volume and pressure.

4)Eye receive stimulus, i.e., vision of ball. Receptor receives stimulus and stimulates nerve endings.
