A&p Exam 1

Front 1

Name 3 lipid soluble hormone classes

Back 1

1. Steroids
2. Thyroid
3. Nitric oxide

Front 2

Name 3 water soluble hormone classes

Back 2

1. Amines
2. Peptide and Protein
3. Eicosanoid

Front 3

circulating hormones

Back 3

secreted into the interstitial fluid and then moved into the blood for distribution around the body

Front 4

local hormones

Back 4

These are secreted into the interstitial fluid and affect local cells instead of being distributed via the blood

Front 5

2 classes of local hormones

Back 5

1. Autocrine
2. Paracrine

Front 6

Paracrine hormones

Back 6

local hormones that affect neighboring cells, and generally maintain the local physiology

Front 7

Autocrine hormones

Back 7

local hormones that affect the cell that secreted them, and are normally used as a positive feedback to stimulate the cell in some physiological activity

Front 8

Hormonal effects include

Back 8

1.synthesis of new molecules
2.changing the permeability of the plasma membrane
3.stimulating transport of a substance into or out of the target cells
4. altering the rate of specific metabolic reactions
5. causing the contraction of smooth muscle or cardiac muscle
4.

Front 9

Hormonal effects include

Back 9

1. Alters plasma membrane permeability or membrane potential by opening or closing ion channels
2. Stimulates synthesis of proteins or regulatory molecules such as enzymes within the cell.
3. Activates or deactivates enzymes
4. Induces secretory activity
5. Stimulates mitosis

Front 10

Permissive effect

Back 10

the actions of some hormones on target cells requires a simultaneous or recent exposure to a second hormone.
Sometimes the permissive hormone increases the number of receptors for the other hormone, and sometimes it promotes the synthesis of an enzyme required for the expression of the other hormones effects

Front 11

Synergistic effect

Back 11

When the effect of two hormones acting together is greater or more extensive than the effect of each hormone acting alone

Front 12

Antagonistic effects

Back 12

When one hormone opposes the actions of another hormone

Front 13

3 types of signals that can control hormone secretion

Back 13

1. Signals from the nervous system
2. Chemical changes in the blood.
3. Other hormones

Front 14

anterior pituitary gland cells

Back 14

1. Somatotrophs
2. Thryrotrophs
3. Gonadotrophs
4. Lactotrophs
5. Corticotrophs

Front 15

Somatotrophs secrete

Back 15

Human growth hormome (hGH)

Front 16

Thryrotrophs secrete

Back 16

Thryroid stimulating hormone (TSH) or thyrotrophic

Front 17

Gonadotrophs secrete

Back 17

follicle stimulating hormone (FSH) and luteinizing hormone (LH)

Front 18

Lactotrophs secrete

Back 18

prolactin (PRL)

Front 19

Corticotrophs secrete

Back 19

adrenocorticotropic hormone (ACTH) or corticotropin
- melanocyte-stimulating hormone (MSH)

Front 20

tropins

Back 20

hormones that influence another endocrine gland
