Worksheet time: 24mins
The endocrine glands are ductless glands. Therefore, the hormones are secreted directly into the blood flow. Although the hormones are transported throughout the body in the blood, the hormones only influence and affect specific target cells because
The hormones have specific molecule receptors
The target cells have specific molecule receptors on its membrane surface
The walls of blood capillaries are only permeable to a certain type of hormone
The hypothalamus controls the hormone to be transported to the target cell
Which gland is the main gland of the endocrine system?
Thyroid gland 甲状腺
Adrenal gland 肾上腺
Hypothalamus 下丘脑
Pituitary gland 脑垂腺 / 垂体
Why is the pituitary gland considered the main gland of the endocrine system?
It sends nerve impulses to other endocrine glands to control their secretion of hormones
It secretes hormones that control the secretion of other endocrine glands
It has the largest size
It is located below the hypothalamus
The posterior lobe of the pituitary gland 脑下垂体后叶 secretes
GH 生长素
ADH 抗利尿激素
ACTH 促肾上腺皮质激素
Oxytocin 催产素
The function of oxytocin 催产素 includes
Stimulates the contraction of uterine muscles 子宫肌肉收缩 during birth
Stimulates ovulation 排卵
Stimulate the development of follicles in the ovary 促进卵泡发育
Stimulates the production of milk from the mammary gland 乳腺
Which of the following is NOT secreted by the anterior lobe of the pituitary gland? 脑垂体前叶
