Exocrine gland

exocrineexocrine glandssecretory gland
Holocrine is a term used to classify the mode of secretion in exocrine glands in the study of histology.
Holocrine secretion – the entire cell disintegrates to excrete its substance; for example, sebaceous glands of the skin and nose.

Apocrine

apocrine glandsapocrine gland
Holocrine gland secretion is the most damaging (to the cell itself and not to the host which begot the cell) type of secretion, with merocrine secretion being the least damaging and apocrine secretion falling in between.
Apocrine secretion is less damaging to the gland than holocrine secretion (which destroys a cell) but more damaging than merocrine secretion (exocytosis).

Meibomian gland

Examples of holocrine glands include the sebaceous glands of the skin and the meibomian glands of the eyelid.
The Meibomian gland (often written with a small "m" and also called tarsal gland) is a holocrine type of exocrine gland, at the rim of the eyelid inside the tarsal plate, responsible for the supply of meibum, an oily substance that prevents evaporation of the eye's tear film.

Merocrine

eccrineeccrine ductsmerocrine secretion
Holocrine gland secretion is the most damaging (to the cell itself and not to the host which begot the cell) type of secretion, with merocrine secretion being the least damaging and apocrine secretion falling in between.
The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine).

Sebaceous gland

Examples of holocrine glands include the sebaceous glands of the skin and the meibomian glands of the eyelid.
The type of secretion of the sebaceous glands is referred to as holocrine.

Cytoplasm

Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.

Femoral pore

femoral pores
Femoral pores are a part of a holocrine secretory gland found on the inside of the thighs of certain lizards and amphisbaenians which releases pheromones to attract mates or mark territory.

Uropygial gland

preen glandpreen oiluropygial
It is a holocrine gland enclosed in a connective tissue capsule made up of glandular acini that deposit their oil secretion into a common collector tube ending in a variable number of pores (openings), most usually two.

Secarecytosis

Secarecytosis differs from holocrine and apocrine secretory mechanisms in that it occurs only during development and that portions of cells, complete with their organelles, are lost.

Redback spider

RedbackRedbacksRed Back Spider
The redback and its relatives in the genus Latrodectus are considered dangerous, alongside funnel-web spiders (Atrax and Hadronyche), mouse spiders (Missulena), banana spiders (Phoneutria) and recluse spiders (Loxosceles). Venom is produced by holocrine glands in the spider's chelicerae (mouth parts).

Snakeskin

Most snake glands are holocrine glands, meaning that the gland's cells are secreted along with the substance the gland makes.

Holocrine glands the entire cell disintegrates to secrete its substances. e.g. sebaceous glands : meibomian and zeis glands.

Latrotoxin

alpha-latrotoxinα-latrotoxinalpha-latrotoxin receptor
The cytosolic α-LTX precursor molecule is released from the cell by means of holocrine secretion where it ends up in the venom gland of the spider.
