Muscle Tissue
How many types of muscle tissue are there and what are they called?
There are three types of muscle tissue.
Skeletal Muscle
Cardiac Muscle
And Smooth Muscle
The characteristics of muscle tissues are divided into four different categories. True/False
True
What are the 4 most important muscle functions?
The four important muscle functions are producing movement, maintaining posture and body position, stabilizing joints, and generating heat.
The force of muscle contraction depends on...
The number of myosin cross bridges that are attached to actin.
The protrusion of an organ through a body cavity wall is called what?
Hernia
What muscle tissue has the longest muscle cells and has obvious stripes called striations?
Skeletal Muscle
What is Excitability?
A cell can receive and respond to a stimulus by changing its membrane potential.
How do muscles generate heat?
What relies more on anaerobic glycolysis and creat phosphate?
Glycolytic Fibers
What is Myalgia?
Muscle pain form any muscle disorder.
What muscle is responsible for the body's overall mobility?
The Skeletal Muscle
The ability to shorten forcibly when adequately stimulated is what?
Contractility
When maintaining posture and body positions the skeletal muscles function almost continuously making one tiny adjustment one after the other to fight the downward pull of gravity. True/False
True
They contract quickly, are oxygen-dependent, and have a rich supply of myoglobin and capillaries.
Fast Oxidative Fibers
Any disease of a muscle is called?
Myopathy
Only occurs in the heart and in NOT voluntary
Cardiac Muscle
What is the ability to extend or stretch?
Extensibility
What pulls on bones to cause movement?
Stabilized joints
Muscle and sarcomere can stretch to only 100% of its resting length. True or false
False
Acronym for rest, ice, compression, and elevation.
RICE
Which muscle tissue is found in the walls of hollow visceral organs?
Smooth Muscle
Elasticity is the ability of a muscle cell to...
Recoil and resume its resting length after stretching.
Skeletal muscles are responsible for...
All locomotion and manipulation.
What contracts rapidly, uses little oxygen, depends on plentiful glycogen reserves, tires quickly, has a large diameter, and has a few mitochondria, little myoglobin, and few capillaries?
Fast Glycolytic Fibers
Define Starin
Excessive stretching and potential tearing of a muscle can occur due to overuse or abuse of the muscles.
