Connective Tissue
Question | Answer |
---|---|
What are the three structrual elements of Connective Tissue? | Ground substance, fibers, and cell populations. |
What are the three basic fibers in Connective Tissue? | Collagen, elastic, and reticular fibers. |
What is matrix? | A ground substand embedded with fibers that seperate the cells. |
Areolar tissue, adipose tissue, and reticular tissue are all... | Loose connective tissues. |
Desnse regular, dense irregular, and elastice tissues are all... | Dense connective tissues. |
Cartilage, bone, and blood are all... | Specialized connective tissues. |
What is areolar? | Loosely woven fibers embedded in ground substance; many different cell types wander through; fibroblasts from basic tissues. Wraps and cushions organs. |
Where is areolar located? | Papillary dermis of skin, hypodermis, muscous membranes, blood vessles, nerves and around the body. (Everywhere) |
What is the function of areolar? | Strength, elasticity, and support. |
What is adipose? | Closely packed adipocytes that store fats, forming a characteristic "signet ring" appearance. |
Where is adipose located? | Hypodermis, around heart, kidneys, and eyes; yellow bone marrow; around joints. |
What is the function of adipose? | To provide insulation, energy storage, and protection from mechanical injury. |
What is reticular? | Network of very short interacting collagen fibers or fibroblasts. |
Where is reticular located? | Stroma of liver, spleen, lymph nodes, red bone marrow, basement membranes. |
What is the function of reticular? | Forms framework of organs, binds together smooth muscle cells. |
What is dense regular? | Collagen fibers arranged in parallel bundles, with fibroblasts scattered in between. |
Where is dense regular located? | Tendons, aponeuroses, and most ligaments. |
What is the function of dense regular? | Provides strong attatchments to each parts. |
What is dense irregular? | Collagen fibers randomly arranged and fibroblasts, forming a sheet. |
Where is dense irregular located? | Dense fascia, reticular dermis, perichondrium, periosteum, joint capsules, dura mater, membrane capsules, heart valves. |
What is the function of dense irregular? | Strength support and protection. |
What is dense regular? | Collagen fibers arranged in parallel bundles, with fibroblasts scattered in between. |
Where is dense regular located? | Tendons, aponeuroses, and most ligaments. |
What is the function of dense regular? | Provides strong attatchments to each parts. |
What is dense irregular? | Collagen fibers randomly arranged and fibroblasts, forming a sheet. |
Where is dense irregular located? | Dense fascia, reticular dermis, perichondrium, periosteum, joint capsules, dura mater, membrane capsules, heart valves. |
What is the function of dense irregular? | Strength support and protection. |
What is elastic? | Elastic fibers that branch freely, forming sheets or ligaments. |
Where is elastic located? | Lung, elastic arteries, trachea and bronchial tree, true vocal cords, vertebral ligaments, suspensory ligament of penis. |
What is the function of elastic? | Provides extensibility and elasticity to various organs that must be stretched. |
