Flashcards in Chapter One - Epithelial Glands Deck (42)
What type of secretion is when the product is released into a duct or directly onto an epithelial surface?
What is the term for the components that are directly involved with the primary function of a substance?
What are the three ways to classify exocrine glands?
Morphology, method of secretion, product that is secreted
What is the term for the components of a substance providing mechanical or metabolic support?
How are exocrine glands classified by morphology?
Categorized by the shape of the secretory arrangement and the arrangement of the ducts
What is the most common method of secretion of exocrine glands?
Goblet cell, salivary glands, pancreas, all sweat glands in children, and many adult sweat glands are examples of what type of exocrine glands?
Merocrine (eccrine) glands
How do merocrine glands accomplish their method of secretion?
What is a positive feature of exocytosis as a method of secretion of merocrine glands?
No cellular damage
Sebaceous glands and the tarsal (Meibomian) glands of eyelids are examples of what type of exocrine gland?
What makes up the secretory product of holocrine glands?
Entire cell with intact vacuoles
What occurs with the cell itself with holocrine glands?
The cell matures and dies while becoming a part of the secretory product
Holocrine glands are specifically associated with what concept?
Lactating mammary glands, some adult sweat glands (pubic and axillary regions), ceruminous glands in external auditory canal, and ciliary "Moll's) glands are examples of what type of exocrine gland?
Lactating mammary glands, some adult sweat glands (pubic and axillary regions), ceruminous glands in external auditory canal, and ciliary "Moll's" glands are examples of what type of exocrine gland?
What makes up the product of apocrine glands?
Cytoplasm, membrane, and intact vacuoles
What types of exocrine glands are associated with odor?
Holocrine and apocrine
What is the term for the smallest division of a gland that is a group of cells surrounding a cavity?
What is a small group of serous cells attached to a mucus acinus?
What are the contractile cells with epithelial origin?
Myoepithelial cells wrap around what structure?
Myoepithelial cells are found where?
Salivary and sweat glands, lacrimal glands, lactating mammary glands
What is the function of myoepithelial cells?
To assist secretion
What type of exocrine gland produces proteins?
What is the shape of the cells of serous glands?
What are examples of serous glands?
Pancreas, parotid gland, chief cells in stomach
What is the appearance of the nucleus of serous glands?
Round and noticeable
What is the staining characteristic of serous glands?
Tend to pick up stains well
Goblet cells, mucous cells in stomach, and the minor salivary glands in tongue and palate are examples of what type of exocrine gland?
