What kind of Eye muscles are controlled by the autonomic nervous system?
intrinsic eye muscles are controlled by the autonomic nervous system
When a muscle contracts how does actin and myosin get shorter?
When the muscle contracts, it gets shorter. When it relaxes, it gets longer.
Dose a whole muscle contract in a all or none fashion?
No. Only enough muscle fibres are recruited to achieve the task at hand.
Does skeletal muscle need stimulation to contract?
Yes! Although we have total control over these muscles, they still need stimulation to contract. The difference with muscles that we don't control is that we decide if we want to make this stimulation.
What is a geriatric inflammatory disorder of the muscles and joints?
A geriatric inflammatory is disorder of the muscles and joints. This is a type of rheumatoid arthritis and is characterized by pain.
1 of each on each arm. Triceps are in the back of the upper arm while the Biceps are in the front. Both of which run from your shoulder to elbow.
What is the name of the tricep muscles?
The tricpes brachii muscle is one muscle. It is an extensor muscle, meaning that it opens, or extends the arm from the shoulder (as opposed to the bicpes, which is a flexor muscle, that closes the arm.)
Which is the major muscle for breathing?
The Diaphragm.
When the diaphragm contracts, it increases the size of the thoracic cavity (chest), which lowers the air pressure, causing outside air to flow in.
The external intercoastals are also used in breathing. They are the muscles on your ribs, that pull on your rib cage and help to expand the chest cavity.
Muscle Weakness can be caused by a number of reasons, the head of which is neural problems that would cause abnormal contractions in the muscle, making it so you would have to exert more effort to get the same amount of force. Such is the case with Amyotrophic Lateral Sclerosis where motor neurons can no longer stimulate the muscle.
As well, weakness in the muscles can be experienced through exertion, such as long training, as experienced in novice strength trainers, and others (indeed, you may feel the effects when running for long periods of time). This kind of weakness is caused by the inability for the body to provide energy efficient enough to meet the demands of the muscles.
What muscle is the antagonist to the sternocleidomastoid?
i think it's the rectus capi lateralus. could be wrong, but im pretty sure
What type of muscle controls digestion?
Your intestines contain a medial layer of smooth muscle. When the smooth muscle in your intestines is innervated this causes contractions of those smooth muscles. This action then propels food through the intestines. This is called peristalsis. So, as far as I know there are no other muscle groups that aide in digestions. There are however, a plethora of chemicals and enzymes that assist in the digestive process.
When you sneeze do you use every muscle in your body?
intercostal muscles..... they are located under the ribs
Does smooth muscle allow you to move your eyeballs?
No, smooth muscles are involuntary muscles. We can't control smooth muscles by our will. Only striated muscles (also known as skeletal muscles) can be controlled by will.
THE ARM CONSIST OF THE DELTOID, TRICEPS (BACK OF ARM) BICEPS(FRONT OF ARM) AND THEN EXTENSORS( THE MUSCLE GOING UP FROM YOUR THUMB) AND FLEXORS(GOING UP FROM YOUR PINKY) THE LEG IS QUADRICEP CONSISTING OF FOUR MUSCLE GROUPS : * Rectus femoris * Vastus lateralis * Vastus medialis * Vastus intermedius you can find out more from www.bodyteen.com
The zygomaticus muscle is responsible for elevating the corners of the mouth and lips.
Why do you think muscles get tired?
Mucles get tired because you get a lot of work out like if your going to the gym or if you are playing a sport.
The first picture shows a person or people working out in a gym.
The second picture shows two soccer players playing in a soccer game.
What action is controlled by involuntary muscles?
There are several actions made by involuntary muscles such as the pumping of the heart, the expanding and contracting of blood vessels moving blood throughout the body and shivering which are involuntary muscle contractions that created thermal energy to heat up the body when its cold.
Digestion is one. Breathing is another.
Why are muscles important to your skeletal system?
You should have phrased it, "What is the importance of the joints in the skeletal system?" Well you use joints all the time if you don't know that... I will give you an example of why it's so important. If you only had bones without any joints. You would not be able to bend, or twist. You would be EXTREMELY stiff. It would probably be nearly impossible for you to move. Also you would not be able to play Video Games because you have to bend your fingers or twist and rotate them.
Which system is associated with transmission of impulse to the muscles?
The Central nervous systme sends impulses to the peripheral nervous system which in turn carries signals to the muscles.
How do you gain bicep and tricep arm mass in one week?
If you aren't already working out regularly, the first week or two is the easiest to notice results. Just start lifting weights. Use a set/rep ration of about 10-8-6-4. Make sure the last rep of each set is difficult to finish. If not, you're not lifting enough. Also, your muscles will be biggest for up to 60 minutes right after your workout. This is called up pump (increase of blood flow to the area worked on) Biceps are easy, triceps can be a little trickier. Google "tricep exercises" and you should find some good ones.
What is the muscle in your calf called?
The "calf muscle" is the common name for the gastrocnemius muscle which is located below the knee posteriorly between the popliteal space and Achilles tendon. It functions to plantarflex the ankle.
The calf muscle is located on the back of the lower leg, below the knee, between the popliteal space and Achilles tendon. It is made up of two individual muscles, the gastrocnemius and soleus.
How does the integumentary system contribute the cardiovascular system?
One of the functions of the integumentary system is to regulate body temperature. It does so by using the APM (arrector pili muscle) to raise arm hairs and help increase body temperature when cold by using this muscle contraction and to help trap and warm air underneath these hairs.
The circulatory system is also responsible for helping regulate body temperature. It does so by allowing the blood vessels to vasodilate (widen) or vaso constrict (become smaller). When the blood vessels dilate what else does the heat escape through than the integumentary system (the skin).
What part of the brain plays a major role in muscle coordination and posture and balance?
The cerebellum is the area that helps control balance and motor coordination and the coordination of thinking processes. This area undergoes great change and growth during the teenage years.
cerebellum The Cerebellum
