Anatomy & Physiology-Saladin-Ch 17: Endocrine System (Lecture Notes)

Front 1

FSH

Back 1

(FSH) Follicle-stimulating hormone

PRODUCED BY: anterior pituitary

FUNCTION:
stimulates ovarian follicle production in females and sperm production in males.

Front 2

LH

Back 2

(LH) Luteinizing hormone

PRODUCED BY: Anterior pituitary hormone

FUNCTION (FEMALES)
aids maturation of cells in the ovary and triggers ovulation in females.

FUNCTION (MALES):
causes the interstitial cells of the testis to produce testosterone.

Front 3

ACTH

Back 3

(ACTH) Adrenocorticotropic hormone (aka "Corticotropin")

PRODUCED BY: Anterior pituitary hormone

FUNCTION:
influences the activity of the adrenal cortex.

Front 4

GH

Back 4

(GH) Growth hormone (aka "Somatotrophin"-STH)

PRODUCED BY:anterior pituitary

FUNCTION:
(1) that stimulates growth in general
(2) energy metabolism
(3) requires intermediary proteins like somatomedins or (IGF) Insulin-like Growth Factors

Front 5

PRL

Back 5

(PRL) Prolactin- an Adenohypophyseal hormone

PRODUCED BY: Anterior Pituitary

FUNCTION:
stimulates the breasts to produce milk.

Front 6

TSH

Back 6

(TSH) Thyroid-stimulating hormone (aka "thyrotropin") an Adenohypophyseal hormone

PRODUCED BY: Anterior Pituitary

FUNCTION:
regulates secretion of thyroid hormones.

Front 7

Estrogen

Back 7

female sex hormones

FUNCTION:
(1) stimulates female secondary sex characteristics
(2) Necessary for the production of the ovum

Front 8

Progesterone

Back 8

Hormone

FUNCTION:
(1) partly responsible for preparing the uterus for the fertilized ovum.

Front 9

Testosterone

Back 9

Male sex hormone produced by the testes

FUNCTION:
(1) during puberty promotes virilization,
(2) is necessary for normal sperm production.

Front 10

Thyroid gland

Back 10

One of the largest of the body�s endocrine glands; straddles the anterior trachea

Front 11

Glucocorticoids

Back 11

Adrenal cortex hormones that increase blood glucose levels and aid the body in resisting long-term stressors.

Front 12

Adrenal Cortex

Back 12

Outer portion of adrenal gland that produces steroid hormones

Front 13

Adrenal glands

Back 13

Hormone-producing glands located superior to the kidneys; each consists of medulla and cortex areas.

Front 14

Endocrine glands

Back 14

Ductless glands that empty their hormonal products directly into the blood.

Front 15

Hormones

Back 15

Steroidal or amino acid–based molecules released to the blood that act as chemical messengers to regulate specific body functions

Front 16

Endocrine glands

Back 16

Ductless glands that empty their hormonal products directly into the blood.

Front 17

Exocrine glands

Back 17

Glands that have ducts through which their secretions are carried to a particular site.

Front 18

Endocrine system

Back 18

Body system that includes internal organs that secrete hormones.

Front 19

Gland

Back 19

Organ specialized to secrete or excrete substances for further use in the body or for elimination.

Front 20

Pituitary gland

Back 20

Neuroendocrine gland located beneath the brain that serves a variety of functions including regulation of gonads, thyroid, adrenal cortex, lactation, and water balance.

Front 21

The pituitary gland has two major lobes?

Back 21

(1) Anterior Lobe
-glandular tissue
-produces 6 well known hormones

(2) Posterior Lobe
-neural tissue
-releases 2 hormones produced by neurons in the hypothalamus

Front 22

Peptide Hormones

Back 22

A molecule formed by linking amino acids in a chain. Usually contains fewer than 50 amino acids.

Front 23

Which 6 hormones does the anterior pituitary produce

Back 23

Anterior pituitary produces:

1- TSH (Thyroid stimulating hormone)
2- FSH (Follicle-stimulating hormone)
3- LH (Luteinizing hormone)
4- ACTH (Adrenocorticotropic hormone)
5- GH (growth hormone)
6- PRL (Prolactin)

Front 24

Gonadotropins

Back 24

Gonad-stimulating hormones produced by the anterior pituitary.

CONSISTS of 2:
1- FSH
2 - LH
