KNES 2600 Study Guide - Midterm Guide: Superior Gemellus Muscle, Dorsal Root Ganglion, Cervical Plexus
Document Summary
Three types of muscle tissue: skeletal. A. k. a. striated or striped voluntary muscles: cardiac. Forms walls of hear (myocardium: smooth. Controls flow and secretion in blood vessels, hollow organs, digestive system. Produce skeletal movement: pull on tendons to move bones. Maintain posture and body position: stabilize joints to aid in posture. Support soft tissue: support weight of visceral organs. Regulate entering and exiting of material: voluntary control over swallowing, defecation, and urination. Maintain body temperature: some of the energy used for contraction converted to heat. Gross anatomy is the study of: overall organization of muscles, connective tissue associated with muscles, nerves associated with muscles, blood vessels associated with muscles. Microscopic anatomy is the study of: myofibrils, myofilaments, sarcomeres. Muscles classified according to fascicle (bundles of muscle fibers) arrangement: parallel (fusiform) Fascicles parallel to long axis of muscle. Fibers may run the entire length of the muscle or may be interrupted by transverse, tendinous tissue at regular intervals: convergent (fan)
