Che26,p3 Hormones and endocrine system Flashcards
The gonads secrete …..hormones, which are …… and ……
sex hormones, testes and ovary
The gonads also have dual jobs, they produce ……… and secrete ………
gametes, hormones
How are sex hormones released in the body?
Hypothalamus ➡️ Anterior pituitary(FSH)(LH) ➡️ Gonads ➡️ Sex hormones
There are three main types of sex hormones…… …… ……
Estrogen, progesterone and androgen
Estrogen, progesterone and androgen are….. hormones
sex hormones
Estrogen, progesterone, and androgen are hormones found in both females and males in
A) equal proportions
B) different proportions
B) different proportions
Estrogen is high in
A) females B) males
A) females
The sex hormone that effect the development of females characteristics is..
A)estrogen B)progesterone C)androgen
A) estrogen
The hormone that increases during pregnancy is…
A)estrogen B)progesterone C)androgen
B) progesterone
The…… hormone is high in males in the form of ……..
Androgen, testosterone
The sex hormone that stimulates the development of male reproductive system and male characteristics, is
A)estrogen B)progesterone C)androgen(testosterone)
C)androgen(testosterone)
When a person is genetically male -due to a resistance to male hormones- with female physical characteristics, this person has a condition called ……………..
androgen insensitivity syndrome
Another job of ……….. in animals like sea elephants cause male aggression
during mating
A)estrogen B)progesterone C)androgen(testosterone)
C) testosterone
In birds, ……… causes increased singing
testosterone
In deers, ……… causes development of antlers
A) progesterone
B) testosterone
C) androgen
B) testosterone
When there is enough of a certain hormone in the blood, the hypothalamus recieves an order from the anterior pituitary to cease the release of that hormone. This process is called ………
Negative feedback
Pancreas has dual functions, what are they?
Release hormones and digestive enzymes
The main function of pancreatic hormones is………
regulate blood glucose level
The……and……are pancreatic hormones
A) insulin , adrenal
B) insulin , glycogen
C) insulin , glucagon
C) insulin, glucagon
The insulin and glucagon are also called ………….
antagonistic hormones
What specific place in pancreas that release pancreatic hormones?
Islet of Langerhans
Islet of Langerhans also secretes two types of cells ……and …… that secretes insulin and glucagon.
A) beta cells, alpha cells
B) liver cells, muscle cells
A) beta cells, alpha cells
Beta cells release………that leads to blood sugar decreases
A) insulin
B) glucagon
C) glycogen
A) insulin
Alpha cells release………that leads to blood sugar increases
A) insulin
B) glucagon
C) glycogen
B) glucagon
When blood glucose level rising that stimulates the pancreas, which type of cells will release? and this cells will release any hormone?
A) beta cells, insulin
B)alpha cells, glucagon
C) liver and muscle cells, glycogen
A) beta cells, insulin
……… stimulate nearly all cells to take up glucose then blood glucose level decrease
Insulin
So after insulin decrease blood glucose level what will happen?
stimulus for beta cells diminishes (glucose level at “set point”)
Which type of cells that use glucose to form glycogen stores?
A) beta cells
B)alpha cells
C) liver and muscle cells
C) liver and muscle cells
Declining blood glucose level stimulus the pancreas to release ……… that secretes…………into the blood
A) beta cells, insulin
B)alpha cells, glucagon
C) liver and muscle cells, glycogen
B) alpha cells, glucagon
How does glucagon increase the blood glucose level?
Liver and muscle cells break down stored glycogen and return glucose to the blood
So after break down glycogen and return glucose to blood, what will happen?
Blood glucose level increases and the stimulus for alpha cells diminishes(glucose level “at set point” )
There are ……types of diabetes mellitus, and they are called ……
Two, hyperglycaemia
In diabetes……… there are no insulin because of pancreas failure to produce insulin
A) type 1
B)type 2
A) type 1
In diabetes ……… the problem in insulin receptor is not working but pancreas produce insulin normally
A) type 1
B)type 2
B) type 2
