What is the primary similarity that exists between the endocrine and the nervous system? (5 min 2secs)
Delegate your assignment to our experts and they will do the rest.
The main similarity noted entails the fact that they are both regulatory systems that help in controlling body systems.
What are the characteristics of organs in the endocrine system? (7 min 14 secs)
The main characteristic that defines organs in the endocrine system is that they secrete hormones targeting specific organs or tissues to define body functionality.
Define a hormone. What are the three types of hormones? (11 min 32 secs)
A hormone can be defined as a signaling molecule that is transported by the circulatory system to aid in regulation of physiology and behavior. The lipid-derived, amino acid-derived, and peptide are the major types of hormones.
How does the system promote homeostasis in the body? (12 min 9 secs)
The endocrine system promotes homeostasis through the release of hormones into the blood and helps in the regulation of stimulus; thus, promoting homeostasis in the body.
How does the steroid hormones work? (17 mins 43 secs)
The functionality of the hormones can be seen from the fact that they aid in modulate gene expression in the specific target cells.
How does the non- steroid hormones work? (18 mins 54 secs)
The non-steroid hormones function by enhancing a bind to plasma membrane receptors, which, in turn, aids in the generation of a chemical signal.
How do the negative feedback systems work? (25 mins 27 secs)
Negative feedback systems work by decreasing functionality of the body systems as a response to specific types of stimulus.
What are three examples of how hormone release is triggered? (29 mins 9 secs)
Hormones can be triggered by humoral, hormonal, and neural stimuli.
What is the primary factor that triggers the anterior pituitary to release hormones? (33 mins 18 secs)
Stress is the primary factor that hormones from the anterior pituitary.
What are some of the effects of Human Growth Hormone (HGH)? (36 min 17 secs)
Some of the notable effects that can be associated with the Human Growth Hormone (HGH) include carpal tunnel syndrome, insulin resistance, and edema.

Describe the central function the hypothalamus. (3 min 22 secs)
The central function of the hypothalamus is to release neuroendocrine through its control of the anterior pituitary to aid in the release of hormones.
Describe the pituitary hormones involved in reproduction? (6 min 19 sec)
The Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are the primary pituitary hormones that have a significant role in the process of reproduction.
What are the effects associated with too much or too little thyroxine? (8 min 24 sec)
One of the notable effects associated with too much or too little thyroxine is that this may result in the release of thyrotoxicosis, which is likely to cause goiter.
How are Ca++ levels regulated within the blood? (10 mins 39 secs)
The Ca++ levels in the blood are regulated by parathyroid hormone (PTH), which helps in increasing calcium levels focusing on the skeleton, the kidneys, and the intestine.
How does the pancreas take part in controlling the level of glucose in the blood? (14 min 17 secs)
As a measure to control the level of glucose in the blood, the pancreas aids the release of insulin, which helps in lowering the levels of glucose.
How is the release of epinephrine stimulated? (18 mins 19 secs)
The most common trigger for the release of epinephrine is when an individual has been exposed to stress stimuli.
Define an “EpiPen”. When is it used? (20 mins 21 secs)
EpiPen refers to an injection that that aids in the narrowing of the blood vessels by creating opening within the lungs to help deal with conditions such as anaphylaxis, cardiac arrest, and superficial bleeding.
What is the main difference between type I and type II diabetes? (26 min 14 sec)
The major difference between the two conditions is based on the release and response to insulin. The individuals with type I have no ability to release insulin while those with type II do not show any form of response to the insulin released into the body.
Describe the hormone that is responsible for regulating the sleep-wake cycle and name the gland that is involved in the release of this hormone? (33 min 25 sec)
The hormone that is responsible for regulating the sleep wake cycle is melatonin, which released by the pineal gland.
What is the function of prostaglandins? (38 min 47 sec)
The main function of prostaglandins is that it helps in the contraction and relaxation of smooth muscle, which play a key role towards controlling blood pressure, as well as, modulation of inflammation.
