chapter 10 muscle tissues

Similar to skeletal muscle cells all smooth muscle cells are excited by ACH

False

Ones genes have a greater impact than exercise habits in determining the proportion of fast twitch or slow twitch

True

Membranous network that wraps around myofibrils

Sarcoplasmic reticulum

Smooth muscle in which cells are individual sent signals

Multi unit

Process of glucose & glycolysis energy yield

2 atp

Increased age skeletal muscle show

Decrease in the number of myofibrils

Myofibril is made of myofilaments

True

Glycosis

Anaerobic process that occurs in the cytosol

Compared too slow twitch fast twitch respond to stimulus with less delay

True

Vascular supply to slow twitch muscles

Is more extensive then the around fast twitch muscles

Structure made to attach muscle to another muscle

Aponeneurosis

Muscle fibers from y shaped branches are joined by intercalated dics are

Cardiac

Muscle that Is passively stretched

Extensibility

Stair case warming up effect

Treppe

Embryonic cells that remain in skeletal muscle tissue are known as satellite cells

True

Fast twitch fibers generate less power then slow twitch

False

Wave summation is demonstrated by

Frequency

Typical skeletal muscle cells contains how many mitochondria

300

Smooth muscles tend to be shorter but thicker then skeletal muscles

False

Force of muscle contraction is

Recruiting different number of motor units

Iris of the eye contains what motor unit

Multi smooth unit

Skeletal muscle fibers in the body are

Fast twitch

Form of smooth muscle

Single unit / visceral

Sacromere depicts relaxed muscle -which identify the m line

4

Sacromere defined as the distance from to the next adjacent

Z disc

Resivors that store calcium

Terminal cisternae

Multiple nuclei muscle cells are a result from

Fusion of myoblasts

Power stroke

A myosin head pulling a thin filament toward the center of the Sacromere
