WARM UP 10/31

1. What is the function of glandular epithelial tissue?

2. What are two types of glands?3. What is the difference between endocrine and

exocrine glands?4. Where would you find transitional tissue?5. Where would you find mucous membranes?6. What tissue type is many layers of cubelike

cells?

NOTES – GLANDULAR EPITHELIAL TISSUE AND

MEMBRANES

Take out your own notes and we will check them

EPITHELIAL TISSUE: 2 types

1. Membranous – lines (8 types off chart)

2. Glandular – glands (secretes)

GLANDULAR EPITHELIAL TISSUE

Function: secretion

2 types of glands:

1. ENDOCRINE – secrete directly into blood or fluid

* They secrete hormones

PITUITARY Hangs from base of brain

Influence growth

Water absorption

Milk secretion

Uterine contractions (labor)

THYROID neck Control metabolic rate

Growth

PARATHYROID Behind thyroid in neck

Calcium salt balance – maintains muscle and nervous tissue

ADRENAL On top of each kidney

Enables the body to cope with emergency situations

PANCREAS

(islets of Lang.)

Right side under stomach

Breakdown nutrients

Blood sugar regulation

OVARIES Pelvic portion of abdominal cavity

Sex characteristics

Menstruation

Eggs cells

TESTES In the scrotum Sex characteristics

Sperm production

2. EXOCRINE – secrete into ducts (tubes)

EX:

1. Lacrimal gland – tears

2. Salivary gland – saliva

3. Sweat gland – water

4. Sebaceous gland - oil

EXOCRINE: 3 types

1. Apocrine – pinch off top part of cell into duct

EX: mammary gland

2. Holocrine – rupture to secret

EX: sebaceous gland

3. Mesocrine – secrete directly through cell

EX: salivary gland (most glands)

MEMBRANES

Thin layer of tissue that covers a surface, lines a cavity, or divides a space or organ

Types of epithelial membranes:

1. CUTANEOUS – skin

2. SEROUS – line closed body cavities; secrete clear lubricating fluid to stop friction; pleura, pericardium, peritoneum

3. MUCOUS – line and protect organs that open to the exterior of the body; mucus keeps it lubricated; digestive and respiratory tract

4. TYMPANIC – eardrum
