Question 1

Indicate the solubility characteristics of each of the classes of hormones by writing the appropriate letter in the blank using the following answer code:
-peptides

Accepted Answer

Peptides are hydrophilic (lipophobic) hormones, meaning that they dissolve easily in water but not in lipids. This is because they contain many polar or charged amino acid residues in their structure.

Question 3

Indicate the solubility characteristics of each of the classes of hormones by writing the appropriate letter in the blank using the following answer code:
-steroids

Accepted Answer

Steroids are lipophilic (hydrophobic) hormones, which means they are soluble in lipids and cannot dissolve in water. They require carrier proteins for transport in the blood, as they do not easily dissolve in the plasma.

Question 4

Indicate whether the characteristics below apply to the endocrine system or the nervous system by writing the appropriate letter in the blank using the following answer code:
-Chemical messengers act at a long distance from their site of secretion.

Accepted Answer

Chemical messengers, such as hormones, are secreted by endocrine glands and travel through the bloodstream to reach distant target cells. The nervous system, on the other hand, uses neurotransmitters to send messages between neurons in a more localized fashion.

Question 6

Indicate whether the characteristics below apply to the endocrine system or the nervous system by writing the appropriate letter in the blank using the following answer code:
-Pancreas has ductless cells that secrete.

Accepted Answer

The characteristic of having ductless cells that secrete is specific to the endocrine system. The pancreas is an example of an endocrine gland with ductless cells that secrete hormones directly into the bloodstream.

Question 7

Indicate the solubility characteristics of each of the classes of hormones by writing the appropriate letter in the blank using the following answer code:
-thyroid hormone

Accepted Answer

Thyroid hormones are lipophilic (hydrophobic) and therefore soluble in lipids but not in water. They require special protein carriers for transport in the blood.

Question 8

Indicate whether the characteristics below apply to the endocrine system or the nervous system by writing the appropriate letter in the blank using the following answer code:
-Duration of action is brief (milliseconds).

Accepted Answer

The duration of action of the nervous system is brief, typically lasting only milliseconds. The endocrine system, on the other hand, has a longer duration of action, with hormones circulating in the bloodstream for minutes or even hours. Therefore, choice B is the correct answer.

Question 9

Indicate whether the characteristics below apply to the endocrine system or the nervous system by writing the appropriate letter in the blank using the following answer code:
-Speed of response is long (minutes to days or longer).

Accepted Answer

The endocrine system secretes hormones that travel through the bloodstream to target cells, which can take minutes to days or even longer to have an effect. The nervous system, on the other hand, can produce much faster responses in a matter of milliseconds or seconds. Therefore, the characteristic of long speed of response applies only to the endocrine system.

Question 10

Indicate whether the characteristics below apply to the endocrine system or the nervous system by writing the appropriate letter in the blank using the following answer code:
-Specificity is dependent on specificity of target-cell receptors.

Accepted Answer

The endocrine system relies on hormones that bind to specific receptors on target cells, making specificity dependent on these receptors.

Question 14

Indicate whether the characteristics below apply to the endocrine system or the nervous system by writing the appropriate letter in the blank using the following answer code:
-Controls activities that require longer duration rather than speed.

Accepted Answer

The endocrine system is responsible for controlling activities that require longer durations rather than speed. This is because hormones released by the endocrine system have a slower onset and longer-lasting effects compared to the neural signals released by the nervous system.

Question 16

Indicate the solubility characteristics of each of the classes of hormones by writing the appropriate letter in the blank using the following answer code:
-catecholamines

Accepted Answer

Catecholamines are hydrophilic (lipophobic) hormones, which means they dissolve in water and are unable to cross the cell membrane without a specific transporter. They bind to receptors on the surface of target cells and initiate a signal transduction pathway.

Question 19

Indicate whether the characteristics below apply to the endocrine system or the nervous system by writing the appropriate letter in the blank using the following answer code:
-Cerebral cortex can influence activities.

Accepted Answer

The cerebral cortex is part of the nervous system and plays a role in influencing and controlling various activities. Therefore, the characteristics apply to the nervous system only.
