Name the three types of muscle tissue found in the body. - Correct Answer ✔✔ Cardiac,
smooth, skeletal
What does it mean that skeletal muscles are under conscious control? - Correct Answer
✔✔ A person can consciously decide to use their muscles to complete an action
What structures are included in the central nervous system? - Correct Answer ✔✔ brain
and spinal cord
Describe a motor action vs. sensory input in terms of the nervous system. - Correct
Answer ✔✔ Motor actions is when the central nervous system sends an impulse to the
muscle. Sensory input is when the nerves carry information from the external
environment.
True or false: The brachial plexus supplies nerves to the lower extremities. - Correct
Answer ✔✔ false
Describe the difference between tendons and ligaments. - Correct Answer ✔✔ Tendons
connect to the skeletal muscle and ligaments conect bone to bone stabilizes the joints
where bones meet.
Describe the meaning of muscle origin and insertion. - Correct Answer ✔✔ The origin is
the bony site of attachment that is stationary during the movement. The insertion is the
bony site of attachment that is moved by the muscle contraction. The origin and
insertion can be reversed in different types of movements.
Describe the meaning of muscle action and innervation. - Correct Answer ✔✔ The
action of the muscle is movement of the body caused by contraction of the muscles
Innervation is providing movement to the muscles fibers for a specific muscle.
