What does the gastrin hormone produce?
HCl, Pepsin and Mucus
What produces the gastrin hormone?
The stomach
What does insulin do?
Allows glucose to enter cells and converts excess glucose into starch
What is glyrogerl?
lower blood levels
What does the Islets of Langerhams produce?
Insulin, Small intestine, adrenal glands, and glucogen
What does the glucogen hormone do?
raises blood sugar levels by converting starch into glucose
the small intestine has clumps of endocrine tissue that produce what?
secretion hormone
The secretion hormone signals the pancreas to realize its digestive system enzyme needs to go into what?
the duedenum
The adrenal cortex (cortisol) does what?
regulates metabolism
"THE" hormone of pregnancy
progesterone
what does chorionic gonadotropin stimulate?
the corpus luteum to produce progesterone
how is hormone production regulated?
by negative feedback
Too much of a hormone is called
hyper function
too little of the hormone is called
hypo function
Too much hormone while person's growth zones are present is called
gigantism
too much somototrophin after growth zones have dissappeared is called
acromegaly
acromegaly is
enlarged jaw, brow, heavy bones
thyroid gland is refered to as
thyroxine
too much thyroxine is
hyperthyroidism
systems of hyperthyroidism
never tired, no weight gain, hot to the touch, exophthalimia (bulging eyes)
symptoms of hypothyroidism
always tired, easy weight gain, cold to the touch, enlarged thyroid (goiter)
Symptoms of diabetes mellitus
high blood sugar levels, organs and tissues starved for glucose, frequent urination and thirst, blurred vision, tired
production of sperm
spermatogenisis
28 day Cycle with NO pregnancy. what happens on day 14
secondary oocyte locked in Metaphase II is released (ovulation), yellow scar is formed called corpus luteum, corpus luteum becomes an endocrine gland which will produce progesterone, "the" hormone of pregnancy
day 21 of cycle with NO pregnancy
pituitary is producing high levels of RH which is causing the corpus luteum to produce high levels of progesterone
day 28 of NO pregnancy
falling levels of LH and progesterone cause a reduction of blood flow to the endometrium. without adequte O2 and glucose the endometrium dies (necrotic endometrium)
day 1-5 of NO pregnancy
necrotic endometrium and blood are released from body as menstrual flows
High levels of progesterone feedback negatively on placenta shutting off what?
chorionic gonadotropin
during months 4-9, placenta produces
progesterone
during the 9th month, oxytocin released from posterior lobe of pituitary causes
labor contractions and milk letdown
Days 5-12 on menstrual cycle WITH pregnancy
anterior lobe of pituitary gland releases FSH which causes all 440,000 primary oocytes to begin a developmental "race." estrogens are produced.

Day 12 high levels of FSH cause primary follicles to produce high levels of estrogens feedback negatively on the pituitary which results in FSH being shut off, resulting in estrogens to shut off.
Day 14 WITH pregnancy causes:
1. ovulation 2. Formation of Corpus Luteum 3. CL to produce progesterone
Day 21 WITH pregnancy
High levels of progesterone produced by corpus luteum feedback negatively on the pituitary to shut off LH
On Day 21 the zygote has done what?
it has been carried by cilia to the uterus where it has implanted into the endometrium and formed the mother/baby connection
any male with a sperm count of less than 20 million sperm per cc is called
infertia
as soon as placenta is formed it...
begins to produce chorionic gonadotropins which take the place of LH to continue to stimulate the corpus luteum to produce the hormone of pregnancy
anterior lobe of pituitary produces prolactin which stimulates...
mammary glands to produce milk
pregnancy tests test for
the presence of chorionic gonadotropin
extopic pregnancys result when
the zygote implants at a site other than the endometrium of the uterus
most common type of ectopic pregnancy
tubal pregnancy
taste buds are located on
tongue, hard palate, soft palate, pharynx
four kinds of taste buds
sweet, sour, bitter, salty
colored part of the eye
iris
white part of the eye
sclera
hollow area of the eye
anterior chamber filled with aqueous humor= clear liquid
clear part of the eye
cornea
the iris regulates
amount of light that enters the eye
the black hole of the eye is
pupil
the lens of the eye focuses
the image onto the retina
the ciliary body and suspensory ligaments change
shape of lens for focusing
Hypermetropia is caused by
an eyeball that is too short (far sighted)
Myopia is caused by
an eyeball that is too long (near sighted)
3 traits of photoreceptor cones
1. found only in fovea.
2. responsible for color vision
3. only work well in bright light
What focuses the image onto the retina?
lens
Rods are found on the entire retina except for the
fovea
What color is the retina?
beige
the hole of the eye (which is black) is called the
pupil
the iris regulates
the amount of light that enters the eye
the colored part of the eye is called
iris
the clear part of the eye is called
cornea
the posterior chamber filled with clear jelly is called
vitreous humor
male accessory gland fluid contains:
sugar for sperm motility
as soon as placenta is formed, it begins to produce chorionic gonadotropins which take the place of LH to continue to stimulate the corpus luteum to produce the
hormone of pregnancy
human males produce ________ sperm per cc of ejaculate
60 million
high levels of progesterone feedback negatively on the pituitary which causes
it to stop the production of LH
NO pregnancy. What happens on Days 1-5
necrotic endometrium and blood are released from body as menstrual flows
NO pregnancy. What happens on Day 28
falling levels of LH and progesterone cause a reduction of blood flow to the endometrium. without adequate O2 and glucose, the endometrium dies=necrotic endometrium
NO pregnancy. What happens on Day 21
pituitary is producing high levels of RH which is causing the corpus luteum to produce high levels of progesterone
in the ovary, estrogens produce secondary sex characteristics of women such as
breast development and rounded features
in the testes, the testosterone hormone produces secondary sex characteristics such as
muscle development, lower voice, and beard growth
