Tissues and Membranes

Question 1

Epithelial Tissue

Answer 1

Protects body by covering internal and external surfaces.

All glands are made up of it.

Question 1

Connective Tissue

Answer 1

Connects organs and tissues.

Allows for movement; provides support for other tissues.

Subgroups: Adipose, areolar, dense fibrous, and supportive tissue.

Question 2

Muscle Tissue

Answer 2

Cell material that contracts and moves the body.

Question 3

Nervous Tissue

Answer 3

Reacts to stimuli and conducts an impulse.

Controls emotions.

Allows for learning and memory.

Five senses.

Question 4

Membrane

Answer 4

Two thin layers of tissue formed together.

Question 5

Types of Epithelial Membranes

Answer 5

Mucous membranes

Serous membranes

Cutaneous membranes (skin)

Question 6

Mucous Membranes

Answer 6

Line surfaces that lead to outside the body.

Line respiratory, digestive, and urinary systems.

Produces mucus, lubricates and protects lining.

Respiratory mucosa, gastric mucosa, intestinal mucosa.

Question 7

Serous Membranes

Answer 7

Double walled membrane.

Parietal- outer part
Visceral- part that covers the organs

Produces serous fluid, lines the closed body cavities.

Allows organs to move freely, prevents friction.

Pleural membrane, pericardial membrane, peritoneal membrane.

Question 8

Connective Membranes

Answer 8

Two layers of connective tissue.

Synovial membrane
-lines joint cavities
-secretes synovial fluid, prevents friction inside joint cavity

Question 9

Primary Epithelial Tissue Repair

Answer 9

Clean wound: new stratified squamous epithelial cells “push” upward toward surface of skin.

Large skin area: fluid escaping from damaged tissue will dry and seal wound, forming a scab; great or deep area may require skin grafts.

Deep tissue: edges of wound sewn together with sutures.

Question 10

Secondary Epithelial Tissue Repair

Answer 10

Formation of granulation tissue; fluid with strong bactericidal is secreted.
