Do ligaments attach muscles to bone?
I do not think a ligament is a muscle. A ligament is what binds two bones together. That is basically what i know
What might happen if you snapped or tore one of your ligaments?
It would hurt like heck, for one thing. A torn ligament or tendon can hurt worse than a broken bone, which is why a sprained ankle sometimes gives you more trouble than a broken arm. Ligaments and tendons also don't heal back well, and the area will always give you trouble and may develop arthritis as you grow older.
How many types of muscle tissues are there in a muscular system?
Actin and Myosin are the basic muscle tissues.
Do electric muscle stimulator's really work?
The working principle of Electronic Muscle Stimulation is using a small amount of electricity administered through the skin and into the muscle causes muscles to contract. This is the same process that your body goes through when you are working out- each time your muscles contract, they grow a little bit stronger.
But this is only a part of the whole process, to build a muscle, you need to have a balanced diet as well.
Where exactly is a pulled groin muscle?
A pulled "groin" is actually a strained muscle in the upper thigh.
Strained muscles occur when the fibers of the muscle are stretched too far.
The result is a group of torn fibers, or in horrible cases, the entire muscle may tear.
Usually however, it is just a small tear.
If you feel that your muscle has ripped entirely, and you are in a lot of pain, PLEASE GO SEE A DOCTOR! You probably need surgery to correct this problem.
If it is a minor strain, and you are not in agony, a doctor will not be able to do much for you.
REST is the key!
If you pulled your groin within 48hrs ago, you should be icing it as much as comfortable.
After that point, gentle heat applied to the affected area before any physical activity is recommended, as this will help loosen the torn muscle.
I am not a doctor, I'm just a kid, none of this should be taken as scientific fact.
What muscles work together to straighten your leg?
The muscles used to straighten the leg are commonly known as the Quadriceps, a group of four muscles on the front of the thigh. This, however, is only the cast when the knee is isolated. If you were to stand up from a squatted position, you would also be using your gluteal muscles as well as your hamstrings to extend the thigh and stabilize the knee, while your quads and inner thigh muscles (the adductor) help to straighten the the knee. You would also be using your calf muscles to straighten the ankle.
What is the antagonistic muscle to the pronator teres?
This is mostly achieved by the Pronator Teres and hte Pronator Qudratus muscles.
What are the actions from the constructions in respiratory muscles?
Muscles of inspiration include: diaphragm, scalenes, pectoralis minor, and external intercostals. The muscles of expiration include: abdominals and internal intercostals.
How many muscles to lift a finger?
There are no muscles in the human finger. The muscles that bend the finger are located in the palm and in the mid forearm, and are connected to the finger bones by tendons, which pull on and move the fingers.
What part of the vertebrae provide levers against which muscles pull?
spinous process and transverse process
In cardiac muscle the fast depolarization phase of action potential is the result of?
increased membrane permeability to sodium ions
Mitochondrion what would happen if it did not function properly?
A zygote would not pass its "self-test". Embryos screen for several genetic conditions, including impotent mitochondria. The lysosomes of the developing child will explode and apopstosis or "programmed cell suicide" will occur. Theoretically however, an organism could live for a short time without mitochondria. We would just undergo anaerobic respiration but eventuall atrophy from the lactic acid by product. Please read about the Electron transport chain (to understand the importance of mitchondrion) and feel free to comment me if you would like a copy of an article I recently wrote about it.
How skeletal muscle differs from cardiac muscle?
Functions of Skeletal Muscle Tissue
- Skeletal muscles function in pairs to bring about the co-ordinated movements of the limbs, trunk, jaws, eyeballs, etc.
- Skeletal muscles are directly involved in the breathing process.
Functions of Cardiac (Heart) Muscle Tissue
- Cardiac muscle tissue plays the most important role in the contraction of the atria and ventricles of the heart.
- It causes the rhythmical beating of the heart, circulating the blood and its contents throughout the body as a consequence.
What is the difference between voluntary and involuntary muscles and why do you need both?
voluntary muscles are muscles that work when you make them. involuntary are muscles that just go when you don't think about.
How many sternomastoid muscles are in the human body?
There are two sternomastoid muscles in the human body. The sternomastoid is also known as the sternocleidomastoid.
What are 2 things that your muscle rely on?
Muscles during exercise need an adequate supply of glucose and oxygen. Heart rate increases during exercise to provide this supply.

Is it possible for one arm to be say stronger than the other arm?
Yes. People may tend to use their dominant side (if they're left or right handed) more often, causing it to be slighly stronger than the other. Usually the difference is very slight, but extreme differences can cause one side to be underdeveloped, resulting in awkward posture and gait. Any differences can usually be corrected by training of the weaker side with weights and other resistance exercises.
