Chapter 10 Efferent Peripheral Nervous System

Front 1

Skeletal muscle

Back 1

function of skeletal muscle is to produce movement by either moving bones relative to other bones or moving soft tissues relative to bones
-produces movement: isotonic,concentric and eccentric contractions
-maintain body posture and body position
-support soft tissues genitalia, abdomen and internal structure of the neck
-Guard entrances and exits GI tract & urinary tract
-Maintain body temp shivering to warm, vasodilation to cool
known as the "muscle body" typically attached to bone by tendons but may not be attached to bone at all in many cases

muscle fascicle

Back 2

muscle fascicles are the stringy part if meat and are bundles of muscle cells

Front 3

muscle fiber

Back 3

muscle fibers are lone (75cm) multi-nucleated skeletal muscle cells

Front 4

myofibril

Back 4

protein filaments found within the muscle fibers. made from sarcomeres

Front 5

sarcomere

Back 5

sections of myofibril from z-line to z-line. it is the contractile unit of muscle

Front 6

tendon

Back 6

tendon (or sinew) is a tough band of fibrous connective tissue that usually connects muscle to bone[1] and is capable of withstanding tension.Tendons and muscles work together and can only exert a pulling force

Front 7

t-tubles

Back 7

invagination of the outer memberand of muscle fibers that allow action potentials to spread past the sarcoplasmic reticulum surrounding every sarcomere within a muscle fiber

Front 8

sarcoplasmic reticulum

Back 8

endoplasmic reticulum of the skeletal muscle

Front 9

sarcolemmma

Back 9

cell membrane of the skeletal muscle fiber

Front 10

myosin

Back 10

Myosin is a protein that makes up myofibrils with actin. It is the thick filament
