Chapter 4 Part 3 Tissue

Which type of membrane is also an organ system

cutaneous membrane

Endothelium covers and lines internal cavities such as the pleural and peritoneal cavities.

false

Pseudostratified epithelium consists of multiple cell layers.

false

Which tissue repair process results in the formation of scar tissue?

fibrosis

Why does an open wound need a bed of granulation tissue for wound healing to occur?

granulation tissue forms new capillary beds that provide oxygen-such blood for the healing process

What are the local clinical signs and symptoms of the inflammatory stage of wound healing?

pain, swelling, redness, and heat

All of the following statements refer to events of tissue repair. Put the events in proper numbered order according to the sequence of occurrence. The initial event, the injury, is already indicated as number one. 1. The skin receives a cut that penetrates into the dermis and bleeding begins. 2. Epithelial regeneration is nearly complete. 3. Granulation tissue is formed. 4. Blood clotting occurs and stops the blood flow. 5. The scar retracts. 6. Macrophages engulf and clean away cellular debris. 7. Fibroblasts elaborate connective tissue fibers to span the break.

All epithelia have an apical surface and a basal surface.

true

A 6-year-old child fell off his bike and scraped his knee. What is the first stage of wound healing, and what occurs during this stage?

Inflammatory stage, characterized by dilation and increased permeability of capillaries, movement of white blood cells and plasma into the area, clot formation, and removal of foreign material and cell debris.

Which tissues have no functional regenerative capacity?

cardiac muscle and nervous tissue in the brain and spinal cord

Select the correct statement regarding tissue repair.

inflammation causes capillaries to dilate and become permeable
