Hole's Essentials of A&P Chapter 5: Tissues
| Question | Answer |
|---|---|
| Name the 4 major tissue types in the body. | Epithelial, Nervous, Muscle, Connective |
| Where can epithelial tissues be found | Covers organs, inner linings of body cavities, hollow organs |
| Where can nervous tissues be found | Brain, spinal cord, nerves |
| Where can muscle tissues be found | attached to bones, walls of hollow internal organs, heart |
| Where can connective tissue be found | widely distributed throughout body |
| Epithelial tissue function | protect, secrete, absorb, excrete |
| Nervous tissue function | transmit impulses for coordination, regulation, integration |
| Muscle tissue function | movement |
| Connective tissue function | bind, support, protect, fill spaces |
| Difference between between exocrine and endocrine glands. | exocrine-secrete enzymes into ducts, endocrine-hormones directly into the blood rather than through duct |
| Define extracellular matrix | holds signals that directs cells, differentiate cells and build themselves into specific form. Made up of mostly collagen |
| Three major types of connective tisue cells | a. Fibroblasts b. Macrophages c. Mast cells |
| Distinguish between collagen and elastin. | Collagen-flexible,slightly elastic. Resist considerable pulling force, hold ligaments and tendons together. Elastin-thin, weaker, easily stretched and deformed |
| Types of loose connective tissue (3) | a. Areolar tissue b. Adipose tissue c. Reticular connective tissue |
| Define dense connective tissue | packed, thick, collagenous fibers and a network of elastic fibers. Very strong to withstand pulling forces. Binds body parts in form of tendons and ligaments. |
| Hyaline cartilage | most common cartilage, very fine collageous fibers, on ends of bones in many joints |
| Elastic cartilage | cartilage type, dense network of fibers, framework for external ears, parts of larynx |
| Fibrocartilage | very tough cartilage. Acts as shock absorber. Forms pads (intervertebral disc) cushion bones in knees and pelvic girdle. |
| The fluid extracellular matrix of blood is called | blood plasma- contains formed elements such as erythrocytes, leukocytes, and platelets |
| Skeletal muscle tissue | muscles attached to bones, striated, long threadlike cells, voluntary |
| Smooth muscle tissue | muscles make up walls of hollow organs, spindle-shaped, involuntary |
| Cardiac muscles tissue | muscles of the heart, striated and branched, involuntary |
| Distinguish amongst neurons and neuroglia. | neurons-transmits electrial impulses along axons, impulses to brain along spinal cord, cannot undergo mitosis. Neuroglia- cell to cell communication, support neurons, act as nerve glue, undergo mitosis |
| Epithelial Tissue Characteristics | Tightly packed cells, little intercellular material, lacks blood vessels, replaced frequently, prominent nuclei |
| Merocrine Glands | glands release fluid products by exocytosis, and are grouped as serous which produce a watery fluid; or mucus, which produce a thicker, protective substance |
| Apocrine Glands | glands lose portions of their cell bodies during secretion |
| Holocrine Glands | glands release entire cell (oil glands in skin) |
| Connective Tissue Characteristics | Abundant matrix, good blood supply, serves as framework |
| Types of cartilage (3) | a.hyaline b.elastin c.fibrocartilage |
