LAB #2 QUESTIONS
PART A: ENDOCRINE GLANDS OF THE HUMAN
1. Complete the following chart: Please see the attached chart for the Endocrine System.
2. Explain the mechanism of communication, control, and integration in the endocrine system.
The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it regulates body functions in order to maintain homeostasis. The communication and control function of the Endocrine System are key parts in order for the body to maintain homeostasis. The Endocrine and Nervous system unify to make the body work as a unit because they communicate and control.
3. Most hormones are controlled by negative feedback. Explain how, citing a specific example.
While listening in lecture, the most interesting example of negative feedback was what occurs at the beginning of a pregnancy. The Placenta is a temporary Endocrine gland during pregnancy, which is located in the uterus. When a woman becomes pregnant the placenta starts developing and secretes Human Chorionic Gonadotropin (HCG), the Corpus Luteum remains and secretes progesterone for a healthy and successful pregnancy.
PART B: ENDOCRINE GLANDS OF THE CAT AND SHEEP BRAIN
1. What differences did you note between the endocrine systems of the cat and human?
The differences I noticed in the Endocrine systems of the cat versus the human were obviously the size of our organs versus the cat, but also the location of different glands, such as the pancreas and the thymus. The thymus in the human is located inferior to the larynx in the neck and as a cat grows older the thymus almost disappears completely.
PhysioEx Exercise 28B - QUESTIONS 1. a. Sample 1: 104 mg/dl glucose

c. Sample 3: 132 mg/dl glucose
d. Sample 4: 122 mg/dl glucose
