Muscle group that allows you to draw your legs to midline?
Adductor muscles allow the bringing of the leg toward the midline of the body. In contrast, abductor muscles allow limbs to be drawn outward away from the body.
What is a strain like a muscle strain?
A strain is when you tear the muscle tissue slightly by over-stretching it. They occur when you put too much stress on the muscle - for example, by trying to lift something too heavy or by twisting too far.
Does the muscular system stabilize joints?
YES.
Muscles work to cause movements about the joint but also stabilize the joint.
Muscular weakness of uncoordinated muscle activity about a joint increases the rate of joint destruction
What is the muscle that contracts to let air in and relaxes to push out air?
The primary muscle responsible for air entering the lungs is the diaphragm. The diaphragm is a dome-shaped muscle that lies just below your lungs, internally separating the thoracic cavity from the abdominal cavity. When you take in a deep breath, your diaphragm (along with other accessory muscles) contracts and flattens while your chest wall expands creating a negative pressure within the thoracic cavity. This allows air to move from an area of high pressure to an area of lower pressure during inhalation.
What two muscles abduct the thigh?
The psoas major and the iliacus (which together make up the iliopsoas) are located in the abdomen but function to move the thigh. The psoas major originates on the body and transverse process of T12-L5. The iliacus originates on the iliac fossa of the ilium. They both insert on the proximal part of the femur.
When you flex your arm muscle what happens?
The muscle in your arm contracts. The muscle on the other side of your arm, opposite from the side that you are flexing, stretches.
What is the antagonist muscle of the mandible?
The antagonist muscle opposes a movement, slows it down and returns the appendage to is natural position once the movement is complete. They work in conjunction with agonist muscles in creating a balanced movement and return.
What muscle dorsiflex and everts ankle?
The Fibularis (Peroneus) Longus, Fibularis (Peroneus) Brevis, and Fibularis (Peroneus) Tertius.
Is the butt one of the strongest muscle in the body?
Absolutely.
Its possible to pull any muscle and the Gluteus Maximus and minimus (the two major muscles in your butt) are no exception.
I think the same because its very posssible and important.
What does the internal oblique do?
internal obliques:
- flexing the spine
- support the abdominal contents
- help breathe
- rotate the spine
save the scarecrows!
What sphincter controls the flow between the duodenum of the small intestine?
Bile is produced in the liver and stored in the gall bladder. The presence of lipids in the duodenum causes the release of bile. Ultimately the liver and gall bladder control the release of bile.
Why does the left ventricle have more muscle?
The left ventricle is thicker and more muscular than the right ventricle because it pumps blood at a higher pressure.
By teenage and adult ages, its walls have thickened to three to six times greater than that of the right ventricle. This reflects the typical five times greater pressure workload this chamber performs while accepting blood returning from the lungs veins at ~80mmHg pressure and pushing it forward to the typical ~120mmHg pressure in the aorta during each heartbeat. (The pressures stated are resting values and stated as relative to surrounding atmospheric which is the typical "0" reference pressure used in medicine.)
In short, it has to pump blood to the rest of the body, instead of just the lungs as the right ventricle.
What are the three types of muscles describe each?
Muscle types
1.smooth-lacks striations.
2.Cardiac-formes the wall of the heart:striated:involuntary.
3.Skeletal-ataches to skeleton:straitedvolontary.
What type of nerve sends messages to muscles?
The nerve synapses transmit messages form one nerve to another.
Which two muscle sabducts the thigh to take the at ease stance?
Fibularis brevis & longus These muscles do not abduct the thigh...
Does the heart muscle have the same structure as the arm muscle?
No. Cardiac muscles are involuntary while skeletal muscles are voluntary, meaning you have control of the arm muscles, but not the heart muscles.
What type of muscle fibers does aerobic trainning chiefy work?
ng healthy and working out from besties
What muscles are used in cross trainer?
Cross trainers work out many muscles but mainly they work out the abdominal and arm muscles.
How many muscles move eyeball?
6- superior and inferior rectus. lateral rectus. medial rectus. inferior oblique and superior oblique
How has a cardiac muscle adapted to its function?
the left hand side of the hear is thicker as it has to pump blood all the way around the body where as the right hand side only has to pump blood to the lungs. the heart also has valves to stop flow back of the blood.written by a cat the heart can with stand fast pumping for intense exercise. the heart is different from any other muscle as it acts as a pump for the blood is is always moving, it has two chambers which act as a waiting room for the blood until it it pumped, this time is very short usually about a second written by a cat
What controls the amount of light that enters the eye?
The pupil contracts or expands (dilates) to regulate the entry of light to the retina in the eye.
The iris or colored part of the eye is what controls the diameter of the pupil by covering or uncovering it.
