"Hormonal Regulation" PPT

Description

"Hormonal Regulation" PPT

Part One: Learning Objectives

1. Name the characteristics and types of human endocrine glands and the hormones they secrete;

2. Give examples of how human hormones participate in the regulation of life activities.

3. Tell us the main functions of growth hormone, thyroid hormone, and insulin and the symptoms of abnormal secretion.

Hormone regulation PPT, part 2 content: course exploration

Explore theme one

Endocrine system and hormones

Endocrine glands: Endocrine glands have no ducts, and the secretions (hormones) directly enter the capillaries in the glands and are transported throughout the body along with the blood circulation.

Endocrine system: The endocrine system consists of various endocrine glands.

Endocrine glands and hormones: Under the regulatory control of the nervous system, hormones participate in the life activities of the human body through blood circulation.

Human life activities are mainly affected by the regulation of the nervous system, but are also affected by hormone regulation.

1. Human endocrine system

2. Common endocrine glands

Pituitary gland - secretes growth hormone

Thyroid - secretes thyroid hormone

Thymus gland——secrets thymus hormone

Adrenal gland - secretes adrenaline

Pancreatic islets - secrete insulin

Ovary - secretes estrogen

Testicles——secret male hormones

Explore theme two

Regulatory effects of important human hormones

1. Regulatory effect of growth hormone

Function: Regulates the growth and development of the human body.

Abnormalities:

Dwarfism due to insufficient secretion in childhood.

Hypersecretion in childhood causes gigantism;

Hypersecretion in adults causes acromegaly.

2. Regulatory effect of sex hormones

sex hormones

Androgens (secreted by the testicles)

Estrogen (secreted by the ovaries)

Function: Promote the growth and development of corresponding male and female reproductive organs, stimulate and maintain secondary sexual characteristics.

Testicles: secrete male hormones

The function of male hormones: Promote the growth and development of male reproductive organs, stimulate and maintain male secondary sexual characteristics

3. Regulatory effect of thyroid hormone

Abnormal thyroid hormone secretion

Insufficient secretion in childhood - cretinism

adult

Excessive secretion - hyperthyroidism

Insufficient secretion - hypothyroidism

Iodine deficiency - endemic goiter

Function: Promote growth and development, promote metabolism, and increase the excitability of the nervous system.
