Follicle
* More follicles become functional with regard to oestradiol production.
* Most follicle mites infest follicles
  - hair follicles
* Most follicle mites infest human follicles
  - follicles are surrounded by connective tissue
* Most follicles are surrounded by dense irregular connective tissue
* Most follicles consist of layers
  - tissue layers
  - degenerate or undergo partial development and then disappear
* Most follicles perform functions
  - sensory functions
* Some follicles contain layers
  - fill with keratin
  - grow rapidly
  - have layers
  - induce ovulation
* Some follicles produce estrogens
  - hormones
  - release hormones
  - show areas where colloid is absent
  - stimulate maturation
* Some follicles undergo meiosis
* are directly in contact with the blood
  - fluid filled sacs in which eggs grow to maturity
  - fluid-filled sacs which contain developing eggs
  - less likely to open spontaneously
  - part of hair
  - spheres of cells that house oocytes in ovary
  - structures that hold and support the eggs or ova while they grow
* are the enlarging ova in ovaries, prior to fertilization
  - structures inside the ovaries that produce eggs
  - vesicles
* bulges from surface of ovary into abdominal cavity.
* contains the oocyte.
* continue to increase in size as the animal approaches estrus following weaning.
* develop, and within a few days one matures into an ovum, or egg.
* extends deep into the hypodermis.
* grow in the ovaries.
* have two kinds of protein molecules on their cell membranes.
* is fully mature and bulges from ovarian surface.
* often lie next to a skin gland called a sebaceous gland.
* produce the primary female sex hormones, estrogens.
* then develop and subsequently synchronised oestrus and ovulation occurs.
* undergo atresia at all stages of development.

### body part | vesicle | follicle:

Hair follicle
* All hair follicles remain present in a patient with androgenetic alopecia.
* Many hair follicles are in their resting stage at any one particular time.
* Most hair follicles contain an oil gland called the sebaceous gland.
* Most hair follicles perform functions
* Some hair follicles fill with keratin.
* Some hair follicles have receptors for dihydro-epitestosterone, a male hormone
  - the ability to produce different types of hair at various times
* are body parts
  - capable of producing hairs of various thickness and colors
  - clusters of cells that produce hair
  - complex, self-renewing structures composed of different types of cells
  - in close contact with sebaceous glands
  - located in scalps
  - normally at a slight angle in the skin
  - one of the common sites of cutaneous bleeding
  - solid objects
  - sometimes prominent, giving a peau d orange texture
  - tubelike pockets of epidermal cells that extend into the dermis
  - very sensitive to stress
* become miniaturized, and the hair consequently becomes thinner and shorter.
* can die.
* develop from a complex series of interactions between different elements of the skin.
* find inflamed skin an unhealthy environment in which to grow.
* grow in a repeated cycle.
* have a growing and resting cycle.
* originate in the inner portions of the dermis as well.
* prepare themselves for the resting phase.
* receiving insufficient supplies of protein produce shorter, thinner hairs.
* respond best to laser treatment when in their active growth phase.
* rise from the dermis layer.

Mature follicle
* Some mature follicles induce ovulation.
* have taut, almost transparent walls and contain straw-colored fluid.

Ovarian follicle
* are the basic units of female reproductive biology.
* go through a number of stages of development before reaching maturity.
* roughly spheroid cellular aggregation set found in the ovaries.

Primary follicle
* Some primary follicles have layers.
* are the next stage in folliculogenesis after primordial follicles.
* develop into secondary follicles.
* have two stages.
