[01] Muscle Tissue Types Flashcards
How many types of muscle tissue are there?
Three
Name the types of muscle tissue.
- Skeletal muscle
- Cardiac muscle
- Smooth muscle
What is “Skeletal Muscle”?
It’s a type of muscle that’s attached to the skeleton and helps with voluntary movements.
What is “Cardiac Muscle”?
It’s a type of muscle found only in the heart, responsible for pumping blood.
What is “Smooth Muscle”?
It’s a type of muscle found in the walls of hollow organs like stomach and intestines, controlling involuntary movements.
What is the main function of “Skeletal Muscle”?
Voluntary movement
What is the main function of “Cardiac Muscle”?
Pumping blood
What is the main function of “Smooth Muscle”?
Involuntary movement
How does “Skeletal Muscle” appear under a microscope?
It appears striated with multiple nuclei located at the periphery of the cells.
How does “Cardiac Muscle” appear under a microscope?
It appears striated with one or two centrally located nuclei and intercalated discs between cells.
How does “Smooth Muscle” appear under a microscope?
It appears non-striated (smooth) with one centrally located nucleus.
What does “Striated” mean in the context of muscle tissue?
Striated means the muscle appears banded or striped under a microscope due to the arrangement of the muscle fibers.
What are “Intercalated Discs”?
These are specialized junctions between cardiac muscle cells that aid in the conduction of electrical impulses.
Are “Skeletal Muscles” usually under voluntary or involuntary control?
Voluntary control
Are “Cardiac Muscles” usually under voluntary or involuntary control?
Involuntary control
