Q

What beneficial properties do epithelial tissues exhibit?

A
  • Good adaptive powers

- Good regenerative powers (eg after skin cut)

17
Q

What is a gland ?

A

Collections of secretory epithelial cells (mostly)

18
Q

What types of glands are there ?

A

Exocrine (secrete into tubes), and

Endocrine (secrete into blood).

19
Q

Structurally how may exocrine glands be described?

A

Simple: Tubular or Acinar
Compound: Tubuloacinar

20
Q

What two types of exocrine glands is there?

A

Mucous: Secretes high conc. of proteogylcans
Serous: Secretes high conc. of proteins

21
Q

Name a type of Endocrine gland

A

The Adrenal Cortex (steroid gland)

22
Q

Name the main epithelial component of the liver and the cells it produces

A

Parenchyma: Produces hepatocytes.

23
Q

What function does hepatocytes perform and how are they arranged

A

multiple functions mainly secretion and arranged in rows between blood vessels.

24
Q

What other roles to Parenchyma (Epithelial cells) perform?

A
  • Filtration of blood
  • Partial absorption of filtrate
  • Overall to release urine from kidney
25
Q

What are epithelial cells organised into ?

A

Nephrons

26
Q

What are some of the abnormal functions of epithelial cells?

A
  • over-proliferation
