6.1 Overview of Muscle Tissues Flashcards
What contract or shorten?
Muscles
What are responsible for all types of body movement?
Muscles
What are the (3) three basic muscle types?
- Skeletal muscle
- Cardiac muscle
- Smooth muscle
What are elongated i.e. skeletal & smooth muscle?
Muscle Cells (muscle fiber)
Why is there a contraction of muscles?
It’s due to the movement of microfilaments.
In the terminology, Prefix myo refers to?
Muscle
In the terminology, Prefix mys refers to?
Muscle
In the terminology, Prefix sarco refers to?
Flesh
In the connective tissue wrappings of skeletal muscle, what is the outermost covering; covers the entire muscle?
Epimysium
In the connective tissue wrappings of skeletal muscle, what is around a fascicle (bundle) of fibers?
Perimysium
In the connective tissue wrappings of skeletal muscle, what is around single muscle fiber?
Endomysium
What blends into a connective tissue attachment?
Epimysium
What is a cord-like structure?
Tendons
What is a sheet-like structure?
Aponeuroses
What are the sites of muscle attachment?
- Bones
- Cartilages
- Connective tissue coverings
What muscle has no striations and is uninucleated?
Smooth Muscle
What muscle has a spindle-shaped cells?
Smooth Muscle
What muscle is involuntary or no conscious control?
Smooth Muscle
Where is the smooth muscles located?
Location: walls of hollow organs (viscera): stomach, urinary bladder, respiratory passages
What is the contraction of the smooth muscle?
Contraction: is slow, sustained and tireless
What muscle has striations?
Cardiac Muscle
What muscle usually has a single nucleus and involuntary?
Cardiac Muscle
Where is the Cardiac Muscle located?
Location: heart
What is the contraction of the cardiac muscle?
Contraction: Steady pace!
