Functions and Characteristics Of Skeletal, Smooth And Cardiac Muscles Flashcards
What are the three types of muscle tissue in the human body?
Skeletal, cardiac, and smooth muscle.
True or False: Cardiac muscle is under voluntary control.
False.
Which type of muscle is responsible for moving bones?
Skeletal muscle.
Fill in the blank: Smooth muscle is primarily found in the __________.
Walls of hollow organs.
What is the main function of cardiac muscle?
To pump blood throughout the body.
Multiple Choice: Which type of muscle has striations?
Skeletal muscle.
What type of muscle tissue is involuntary and non-striated?
Smooth muscle.
True or False: Skeletal muscles are attached to the skeleton.
True.
What is the primary characteristic of cardiac muscle cells?
Being branched and interconnected.
Fill in the blank: Smooth muscle contraction is __________ compared to skeletal muscle.
Slower and more sustained.
Multiple Choice: Which type of muscle can regenerate after injury?
Skeletal muscle.
What triggers the contraction of cardiac muscle?
Electrical impulses from the heart’s pacemaker cells.
True or False: Smooth muscle can be found in the digestive tract.
True.
What is the role of intercalated discs in cardiac muscle?
Enable synchronized contractions
Fill in the blank: Skeletal muscle fibers are __________ in shape.
Cylindrical.
Multiple Choice: Which muscle type has the fastest contraction speed?
Skeletal muscle.
What is the primary energy source for skeletal muscle contraction?
ATP (adenosine triphosphate).
True or False: Smooth muscle is responsible for voluntary movements.
False.
What type of muscle is found in the heart?
Cardiac muscle.
Fill in the blank: Cardiac muscle is __________ in nature.
Involuntary.
Multiple Choice: Which muscle type is primarily controlled by the autonomic nervous system?
Smooth muscle.
What is a unique feature of smooth muscle cells?
They can contract in multiple directions.
True or False: Cardiac muscle can function without neural input.
True.
What type of contraction is characteristic of smooth muscle?
Rhythmic and slow contractions.
Fill in the blank: The main function of skeletal muscle is to enable __________.
Voluntary movement.
Multiple Choice: Which type of muscle has the longest contraction duration?
Cardiac muscle.
What mechanism allows skeletal muscle to produce force?
The sliding filament theory.
