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
On top of each
kidney
Calcium salt balance –
maintains muscle and nervous
tissue
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
ADRENAL
Enables the body to cope
with emergency
situations
2. EXOCRINE – secrete into ducts (tubes)
EX:
1.
2.
3.
4.
Lacrimal gland – tears
Salivary gland – saliva
Sweat gland – water
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)
DRAWINGS
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
