What are Permanent cells

cells that cannot undergo mitosis

15

What are Fibroblast?

spindle shaped cells that form connective tissue proper (once a fibroblast is completely surrounded by the matrix, it becomes a fibrocyte)

15

What are Exocrine Glands?

Glands that secrete substances outward through a duct

15

What are Chondrocytes?

Chondro(cartilage) mature cartilage cells

15

What is the Extra cellular matrix?

The chemical substance located between connective tissue cells

15

What type of tissue makes up membranes?

Both epithelial and connective.

15

What is the Purpose and location of mucous membranes?

1. Protection 2. Located in the airway, digestive tract, urinary tract, reproductive tract. All systems that open to the outside of the body.

15

What is Purpose and location of synovial membranes?

joints, lubrication, -it is a non-Newtonian fluid. What else reduces friction in joints? Hyaline cartilage.

15

What is the Purpose and location of serous membranes?

lubrication of organs. Pleurisy: infection of the lining of the lungs. Causes friction, very painful, rubbing can be heard with a stethoscope.

15

What does labile mean? And what is a labile cell?

Changeable, “liable to change; easily altered” A cell that can easily undergo mitosis

15

What type of epithelial tissue is in blood vessels and deep in the lungs? Why?

Simple squamous, it is thin and nutrients can diffuse across it.

20

What happens at the basement membrane?

Nutrients diffuse across it to feed the cells. (basement membrane and above to the free surface are avascular)

15

Which tissue makes up the bladder and why?

Stratified transitional epithelium E, it needs to stretch.

15

Where would you find this and why? What is it called?

Airways, it has goblet cells producing mucous and cilia to move the mucous carrying debris out of the body. Pseudostratified epithelium.

25

what is this called where would you find it and why?

Simple columnar Epithelium- stomach and intestine- complex absorption, secretion and protection

25

What is the difference between a stable cell and a permanent cell?

A stable does not usually undergo mitosis but it can.Healing is a long process. (tendons and ligaments) A permanent cells never undergo mitosis (cardiac muscle)
