Question 4

Question 5

Similarities of the Endocrine and Nervous system

Answer 5

• Both use chemical signals when they respond to changes that might affect homeostasis

Question 6

Differences between of the endocrine and nervous systems

Answer 6

• They have different means of delivering their chemical signals
• Nervous system= composed of nuerons; Endocrine system= composed of glands
• Nervous system= rapid; Endocrine system= slow acting

Question 11

Where are the Steroid Hormones produced?

Answer 11

Ovaries, adrenal cortex, and the testes

Question 12

How do steroid hormones enter a cell?

Answer 12

• Hydrophobic, so they enter the cell the same as lipids

Question 13

Hypothalamus

Answer 13

Acts as the link between the nervous and endocrine systems. Regulates the internal environment through communications with the autonomic nervous system.
