|
A property of all cells, more pronounced in muscle and nerve cells, when stimulated muscle cells respond with electrical charges across the plasma membrane
|
Responsiveness
|
|
Local electrical charges travel rapidly along the fiber iniating the process that leads to contraction
|
Conductivity
|
|
Ability of muscle to contract forcefully and generate tension by pulling on attachment points when stimulated by actin potentials, if the tension is enough to overcome the resistance then the muscle shortens and movement occurs
|
Contractility
|
|
Ability to be stretched without being damaged, smooth muscle is subject to the greatest amount of stretch
|
Extensibility
|
|
Ability to return to its original shape and length after contraction or extension
|
Elasticity
|
|
Striated, unbranched, alternating bands of light and dark, mainly under voluntary control from neurons in the somatic nervous system, unconscious control also plays a part in respiration and posture as examples, muscle cells are muscle fibers or myofibers
|
Skeletal Muscle
|
|
Plasma membrane
|
Sarcolemma
|
|
The cytoplasm
|
Sarcoplasm
|
|
Long protein bundles fills most of the sacroplasm
|
Myofibrils
|
|
Abundant energy storage carbohydrate
|
Glycogen
|
|
Red oxygen storing pigment similar to hemoglobin
|
Myoglobin
|
|
Stem cells that produce the muscle cells
|
Myoblasts
|
|
Unspecilized cells that to a limited extent can reproduce to replace damaged muscle cells
|
Satellite Cells
|
|
Network of smooth ER with terminal enlargements
|
Sarcoplasmic Reticulum
|
|
Terminal enlargements are called
|
Cisternae
