Skeletal Muscles are muscles that move when we want them to. Such as your arm, legs, neck, etc.
Smooth muscles are muscles that move on response to environment, such as food going down your esophagus.
The Cardiac Muscle is only one; the heart. It is both a muscle and an organ. It beats by itself.
2. Slowly stand up, take a few steps around the room, and then return to where you began. Feel and observe all of your muscles that move and the muscles that move them.
a. Make a list of the joints that moved as you moved.
Legs, elbows, shoulders, ankles, toes...
b. List any muscles that were moving while you moved that were not striated muscles.
Intestines, esophagus (I ate a vitamin), stomach, heart.
3. Find out the names of several skeletal or striated muscles; find out what they are attached to and what they do.
The Soleus is a small muscle on the side of the back of your leg. It is one of the many muscles that control the movement of your leg. Others that do that include the Extensor family, the Tibialis muscle, and the Peroneus muscle.
4. Think of five or more people you know who are good at using their muscles in some way. What do they do? Does it make them healthier overall? How do they avoid injuries?
Lets see... Mom:
Whenever she has time, she does yoga. She also does a good combination of pilates and hardcore exercise. She does pilates, cardio, and yoga. She is starting to build up an immunity to the painful stretches and routines. I guess you could say she enjoys it...
Dad works out in the gym every day, usually does bench presses and weights. He often lifts us up, and works out like that. We often go on bike rides together. He enjoys it thoroughly, and rarely feels much pain.
Caeden has full energy and is always climbing something, running, or jumping. He loves it, but usually is injured.
I also know me, of course. I often do acrobatics, such as... well, climbing on bookshelves, jumping off beds, and scaling curtains. I enjoy it thoroughly [as it lasts :( ]. I do annual summer swimming class.
Ryan, my best friend, does lots of sports and fitness. He does hockey, baseball, and soccer. It cuts into his day, but he enjoys it in a grudging sort of way. He has never hurt himself doing it, though.
