apocrine gland

Examples of apocrine gland in the following topics:

• Sweat (Sudoriferous) Glands

  • Sweat glands, also known as sudoriferous glands, are distributed over most of the body surface.
  • Sweat glands, also called sudoriferous glands, are simple tubular glands found almost everywhere on our body. 
  • The other kind of sweat glands are known as apocrine glands. 
  • The apocrine glands are found in places like the armpits, scrotum, anus, and labia majora. 
  • Unlike eccrine glands, the exact function of apocrine glands is unknown and debated. 

• Excretion and Absorption

  • Two types of sweat glands can be found in humans: eccrine glands and apocrine glands.
  • They produce a clear, odorless substance consisting primarily of water and NaCl (note that the odor from sweat is due to bacterial activity on the secretions of the apocrine glands).
  • Apocrine sweat glands are inactive until they are stimulated by hormonal changes in puberty.
  • Apocrine sweat glands are mainly thought to function as olfactory pheromones, chemicals important in attracting a potential mate.
  • The stimulus for the secretion of apocrine sweat glands is adrenaline, which is a hormone carried in the blood.

• Impacted Cerumen

  • It is a mixture of viscous secretions from sebaceous glands and less-viscous ones from modified apocrine glands.

• Characteristics of Mammals

  • Sebaceous glands are located over most of the body.
  • Sweat glands are located over most of the body surface in primates.
  • Apocrine glands, or scent glands, secrete substances that are used for chemical communication, such as in skunks.
  • Mammary glands produce milk that is used to feed newborns.
  • Mammary glands are probably modified sebaceous or eccrine glands, but their evolutionary origin is not entirely clear.

• Skin and Mucosae (Surface Barriers)

  • The epidermis also helps the skin regulate body temperature through sweat pores that connect to underlying sweat glands in the dermis.
  • It also contains the hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels, and blood vessels.
  • In the stomach it is columnar and organized into gastric pits and glands to secrete acids and pepsin.

• Structure of the Skin: Dermis

  • The reticular layer also contains hair follicles, sweat glands, and sebaceous glands.
  • The sweat gland can either be apocrine, such as those found in the armpits and the groin area, or the eccrine glands, which are found all over the body.
  • The sebaceous glands found in the dermis secrete a substance called sebum that helps to lubricate and protect our skin from drying out.

• 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.

• Overview of the Parathyroid Glands

  • The parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone.
  • The parathyroid glands are small endocrine glands—approximately the size of a grain of rice—in the neck that produce parathyroid hormone.
  • Humans usually have four parathyroid glands, which are usually located on the posterior surface of the thyroid gland, or, in rare cases, within the thyroid gland itself or in the chest.
  • The two parathyroid glands on each side that are positioned higher are called the superior parathyroid glands, while the lower two are called the inferior parathyroid glands.
  • The parathyroid gland in relation to the thyroid gland.

• Gland Disorders

• Sebaceous (Oil) Glands

  • Sebaceous glands are found in the skin all over the body (except the palms of the hands and the soles of the feet).
  • The sebaceous glands are microscopic glands found in the skin of mammals .
  • In the eyelids, meibomian sebaceous glands secrete a special type of sebum into tears.
  • In the glands, sebum is produced within specialized cells and is released as these cells burst; sebaceous glands are thus classified as holocrine glands.
