Q

Mucous gland

A

Exocrine gland that secretes mucins which absorb water to form slippery mucus, such as those in saliva

17
Q

Mixed exocrine glands

A

Contain more than one type of gland cell and may produce two different exocrine secretions (could be serous or mucous)

18
Q

How endocrine glands release their secretions?

A

Exocytosis from the gland cells into the fluid surrounding the cell

19
Q

Unicellular glands

A

Individual secretory cells that secrete mucins. There are two types goblet and mucous cells

20
Q

Where are mucous cells found and where are they?

A

Unicellular gland cells that are found in pseudostratified ciliated epithelia.

21
Q

Where are goblet cells and what are they?

A

Unicellular gland cells. They are scattered among simple columnar epithelium of the small and large intestine

22
Q

Secretory sheet

A

Simplest multicellular exocrine gland. Glandular cells dominate the epithelium and release their secretions into an inner compartment

23
Q

What is an example of a secretory sheet?

A

Mucus secreting cells in the stomach

24
Q

What’s an example of a simple tubular gland

A

Intestinal glands. Multicellular

25
Q

What is an example of simple coiled tubular gland?

A

Merocrine sweat glands

26
Q

What are examples of simple branched tubular glands?

A

Gastric glands, mucous glands of esophagus, tongue, and duodenum

27
Q

What is an example of a simple alveolar gland?

A

Not found in adults but is a stage in development of simple branched glands

28
Q

What is an example of a simple branched alveolar gland?

A

Sebaceous glands

29
Q

What is an example of a compound tubular gland?

A

Mucous glands (in oral cavity), bulbo-urethral glands (male reproductive system), testes (seminiferous tubules)

30
Q

What is an example of a compound alveolar gland?

A

Mammary glands

31
Q

What is an example of compound tubuloalveolar gland?

A

Salivary glands, glands of respiratory passages, pancreas

32
Q

Merocrine secretion

A

Method of glandular epithelial cell secretion. Exocytosis puts products onto surface of the cell. Ex: serous cells of salivary glands

33
Q

Apocrine secretion

A

Method of glandular epithelial cell secretion in which the cytoplasm is shed. Ex: Lactiferous cells of the mammary gland

34
Q

Holocrine secretion

A

Type of glandular epithelial cell secretion. Destroys gland cell by build up of secretory product (ex: sebaceous gland cells)

35
Q

What structures does simple squamous epithelia form?

A

Alveoli of the lung, inner lining of the cornea of the eye, mesothelial lining of ventral body cavities, and endothelial lining of blood vessels
