Examples of mammary gland in the following topics:

  • Mammary Glands

    • A mammary gland is an organ in female mammals that produces milk to feed young offspring.
    • All the milk-secreting tissue leading to a single lactiferous duct is called a simple mammary gland; a complex mammary gland is all the simple mammary glands serving one nipple.
    • Humans normally have two complex mammary glands, one in each breast, and each complex mammary gland consists of 10–20 simple glands.
    • Mammary glands develop during different growth cycles.

  • Physiology of Lactation

    • Lactation is the secretion of milk from specialized glands (mammary glands) to provide nourishment to offspring.
    • Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young.
  • Development of the Integumentary System

    • The integument also includes appendages, primarily the sweat and sebaceous glands, hair, nails and arrectores pillorum (tiny muscles at the root of each hair that cause goose bumps).
    • Other regions of the ectoderm form into epithelial columns called cords which will become hair follocles and sebaceous and sweat glands.
    • At 20 weeks gestation, hair begins to grow from sebaceous glands, while sweat glands are formed from coiled cords.
    • Other cords begin to form mammary glands.
  • Glandular Epithelia

    • There are two major classifications of glands: endocrine glands and exocrine glands.
    • Examples of exocrine glands include the sweat glands, salivary glands, mammary glands, the pancreas, and the liver.
    • An endocrine gland is its counterpart.
    • Examples of endocrine glands include the adrenal glands, located atop the kidneys and responsible for the secretion of certain hormones such as adrenaline, cortisol, and others.
    • The sebaceous glands are microscopic glands in the skin that secrete an oily/waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals.
  • Breast Augmentation and Reduction

  • Placenta

    • Human placental lactogen is lactogenic and promotes mammary gland growth in preparation for lactation in the mother.
    • It contributes to the woman's mammary gland development in preparation for lactation and stimulates uterine growth to accommodate the growing fetus.
  • The Anterior Pituitary

    • Its regulatory functions are achieved through the secretion of various peptide hormones that act on target organs including the adrenal gland, liver, bone, thyroid gland, and gonads.
    • Adrenocorticotropic hormone (ACTH), is a polypeptide whose target is the adrenal gland.
    • Thyroid-stimulating hormone is a glycoprotein hormone that affects the thyroid gland and the secretion of thyroid hormones.
    • Prolactin is a polypeptide hormone whose target is the ovaries and mammary glands.
    • Hormone secretion from the anterior pituitary gland is regulated by hormones secreted by the hypothalamus.
  • Ovaries

    • Ovaries in females are analogous to testes in males in that both are gonads and endocrine glands.
    • When oocyte maturation is completed, a luteinizing hormone (LH) surge secreted by the pituitary gland stimulates follicle rupture and oocyte release.
    • Progesterone prepares the uterus for pregnancy and the mammary glands for lactation.
  • Overview of the Male and Female Reproductive Systems

    • One important type of parental care is the use of the mammary glands in the female breasts to nurse the baby.
    • The second category, the ejaculatory fluid-producing glands, includes the seminal vesicles, prostate, and vas deferens.
    • The final category, used for copulation and deposition of the spermatozoa (sperm) within the female, includes the penis, urethra, vas deferens, and Cowper's gland.
    • One of the most significant features of the human penis is the coronal ridge underneath the gland around the circumference of the shaft.
    • During intercourse, this area is lubricated by mucus secreted by the Bartholin's glands.
  • Overview of the Adrenal Glands

    • In mammals, the adrenal glands (also known as the suprarenal glands) are endocrine glands that sit atop the kidneys.
    • In mammals, the adrenal glands (also known as the suprarenal glands) are endocrine glands that sit atop the kidneys.
    • In humans, the right adrenal gland is triangular shaped, while the left adrenal gland is semilunar shaped.
    • Each adrenal gland has two distinct structures, the outer adrenal cortex and the inner medulla—both produce hormones.
    • The adrenal glands are triangular-shaped organs on top of the kidneys.
