1. What are the three types of muscle tissue and where are they found in
the human body?
Answer: The three types of muscle tissue are skeletal, cardiac and smooth.
Skeletal muscle is attached to bones and enables voluntary movement.
Cardiac muscle is found in the heart and pumps blood throughout the
body. Smooth muscle is found in the walls of hollow organs such as the
stomach, intestines, bladder and blood vessels and helps move substances
through them.
2. What are the four main types of bones and what are their functions?
Answer: The four main types of bones are long, short, flat and irregular.
Long bones are longer than they are wide and provide support and
leverage for movement. Examples are the femur, humerus and tibia. Short
bones are roughly cube-shaped and provide stability and shock absorption.
Examples are the carpals and tarsals. Flat bones are thin and flat and
protect vital organs and provide attachment sites for muscles. Examples
are the skull, ribs and sternum. Irregular bones have complex shapes that
do not fit into any of the other categories and perform various functions
depending on their location. Examples are the vertebrae, sacrum and
mandible.
3. What is the difference between tendons and ligaments?
Answer: Tendons and ligaments are both types of dense connective tissue
that connect different structures in the body. Tendons connect muscles to
bones and transmit the force of muscle contraction to move the skeleton.
Ligaments connect bones to other bones and stabilize joints by preventing
excessive movement
