How many muscles does it take to roll your eyes?
In Short... It seems that it either takes one muscle (the Occipitofrontalis) OR two (the Frontalis and the Occipitalis) to lift the eyebrow, depending on what source you choose to listen to. In Long... The Occipitofrontalis is a term used by some to describe a muscle of the human body, with two parts: the "occipital" part/belly, and the "Frontal" part/belly. Other sources consider the Occipitofrontalis to be a structure consisting of two distinct muscles, the Frontalis and the Occipitalis. The Frontalis is thin, of a quadrilateral form, and intimately adherent to the superficial fascia. It is broader than the Occipitalis and its fibers are longer and paler in color. It has no bony attachments. Its medial fibers are continuous with those of the Procerus; its immediate fibers blend with the Corrugator and Orbicularis oculi; and its lateral fibers are also blended with the latter muscle over the zygomatic process of the frontal bone. From these attachments the fibers are directed upward, and join the galea aponeurotica below the coronal suture. The medial margins of the Frontales are joined together for some distance above the root of the nose; but between the Occipitales there is a considerable, though variable, interval, occupied by the galea aponeurotica. The Occipitalis, thin and quadrilateral in form, arises by tendinous fibers from the lateral two-thirds of the superior nuchal line of the occipital bone, and from the mastoid part of the temporal. It ends in the galea aponeurotica. So, take that information and decide, one muscle or two.
Which muscle is the prime mover for extension of the hand?
What is that thin membrane surrounding a muscle fiber called?
its called the plasma membrane or cell membrane. sometimes the semi-permeable plasma membrane.
The Sarcolemma is the plasma membrane specifically surrounding a muscle fiber.
What are the muscle on the back of your calf called?
The thigh is comprised of quite a few muscles. The main muscles that people usually refer to fall into two categories: the hamstring group and the quadriceps group. In the hamstring group (which is the back of the thigh) are the biceps femoris, semitendinosus, and semimembranosus. In the quadriceps group (front of thigh) are the rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis. Some other muscles that are on the thigh are the sartorius, iliopsoas, adductor longus, adductor magnus, and gracilis.
Where in your body can you find supinator and pronator muscles?
In your forearm. Your pronators are located on the anterior surface of your arm, while the supinator is located on the posterior surface. The brachioradialis is another pronator and supinator, which is also in your forearm, and is located on top of the radius. The bicep brachii is another supinator, on the upper half of your arm ( above the elbow)
How do muscles in the esophagus help to move food?
The esophagus helps you by sending the food to the liver. Since the liver is connected to the stomach it is send to the stomach. Next is the small intestine. Keep in mind that the food is getting smaller. The food swirls down the small intestine into the large intestine. It goes throughout the whole entire large intestine and to the colon. Then you need to go to the bathroom. It takes up 10 HOURS to do all that
What extrinsic eye muscle turns the eye up and laterally?
Superior Rectus allows you to look Up & In, whiel the Superior Oblique allows you to look Up & Out.
What is the name of the muscle in the rear-upper thigh?
The muscles in your upper thigh is called Hamstrings.
Hamstrings are one of the strongest muscles in our body. They can also stand high tension that's why it takes long to fatigue those muscles.
Good exercise specially squats can help make hamstrings strong.
Muscle that controls breathing as it contracts and relaxes?
The Diaphragm - a membrane of muscle and tendon, flexes to reduce ambient pressure in the thorax, and cause the lungs to compensate by drawing in air. Exhalation works in reverse.
What muscle has slow prolonged contractions?
Seems this best describes the smooth muscle tissue of the alimentary canal (intestines). This is a rather unhurried way to move the food (bolus) through the body to allow nutrients to be absorbed.
What is scoliosis of the lumbar spine?
Scoliosis of the lumbar spine is an abnormal sideways curve in the spine of the lower back.
What excersises give you wider hips?
There aren't any excersizes to move your hips in a more narrower appearance. An option is surgical bone rebuilding. It is almost impossible to 'push' your hips in to prevent them from being wide. Excersizes can get rid of fat around the hip area, but not the actual bone.
What are the parts of the bicep?
There are two muscle groups on the front of the upper-arm the biceps and brachialis
What type of muscles are smooth muscles?
smooth muscles are involuntarily used muscles. these are present in the digestive system that moves and processes food. this is opposed to striped muscles that are voluntarily moved e.g. biceps; and cardic muscle that is present in the heart.
How do your muscles beomce more pliable?
You are assuming that it is possible to increase the elasticity in your muscles, and it is not clear that it is. Muscles are connected to tendons (that are connected to bones). Muscles and tendons work together. When one uses stretching exercises to increase flexibility, one is actually always stretching muscles along with tendons. It is not really possible to separate them. If you want greater flexibility, do a whole body stretching routine 2 or 3 times weekly. It's very important to stretch muscles and tendons that are warm and full of blood; otherwise, you may injure yourself. So, stretch after exercise rather than before exercise. It is also important to avoid ballistic stretching if you are after increased flexibility. Stretch slowly and try to feel the stretch. Stretch just to the point of discomfort and hold the stretch for at least 20 or 30 seconds. Do not bounce. If you follow these guidelines, your flexibility will gradually improve. Remember, though, that there are great individual differences. Just because someone else is able to do a certain stretch does not mean that you will be able to do it. So, 'listen' to your own body. ----
What are 3 ways in which ATP is regenerated during skeletal muscle contraction?
During a skeletal muscle contraction, the three ways in which ATP is generated are through direct phosphorylation, anaerobic pathway and aerobic respiration. In direct phosphorylation, ADP is phosphorylated by creatine phosphate; in anaerobic pathway, glycolysis and lactic acid formation occur; and in aerobic respiration, 95% of ATP is produced.

How do the muscles and bones move together when kicking a ball?
The nervous system works together with the muscular system by telling the muscles in the legs what to do. The brain is part of the nervous system and since it is the control of the body, it tells the muscles to kick or run. Also, sight is controlled by the nervous system and that is how players get to see the ball and kick it.
There is 10 seconds left and you have the ball this is how to score the soccer ball. The nervous, muscular, and skeleton system work together to help you kick a soccer ball.The brain is part of the nervous system which means the brain can tell different partsof the body to do things called a response, like to tell the body to move its muscles to kick or run. The motor neurons send the stimulus travels through the spinal cord to the brain to to tell the muscle in the leg to kick the ball .The tendons that surround the joint which connects the two leg bones together, supports the muscle to do the movement then contract and relax. Also the nervous system controlls your sight so that the player can see the ball to kick it. Now you know how to kick a soccer ball so go score some goals.
