Muscular System
The muscular system allows humans to move. Muscles also provide strength, balance and heat.

The function of movement in the muscular system?
Muscles are attached to two different bones. When a muscle contracts, it shortens. When it shortens, the shortens the angle between the two bones causing movement.
What happens biologically when you get a muscle cramp?
it is from a lack of water in your body
Edited: Because lack of ATP.
Carbohydrate
In muscle contraction calcium apparently acts to?
Muscle contraction is regulated by calcium ions, which will change thin filament into an activated state by binding to troponin. The binding of calcium to the troponin changes it's shape so the myosin binding sites on the actin (thin filament) are exposed
bind to regulatory sites on troponin to remove contraction inhibition
What are the other names for voluntary muslces?
another name for voluntary muscles are skeletal or striated muscles.
Yes, in that sense muscles can only be voluntary or involuntary as far as I know.
Describe the structure of cardiac muscle?
unlike the heart muscle, which is an involuntary muscle, the skeletal muscles are voluntary(movement by choice). these muscles rely on joint mobility with the skeletal bones for leverage. this joint mobility exists because of the tendons that attach muscle to bones through connective tissue, and the types of connective tissue depends on the joint connecting the bones
The heart is a muscle! A BIG MUSCLE! It isn't like the other muscles in the body because it is the thing that keeps you going. This is the one muscle you don't wanna tear ;)
What Is the joint in the middle of arm called?
it's called an elbow.
The joint in the middle of the arm is the elbow.
elbow
The joint that is used when bending the elbow is aSynovial Joint.
A considerable amount of movement is permitted a all synovial joints and types are subdivided according to the movements.
The elbow would be specifically considered a Hinge Joint: This type permits movement in one plane only. The movements are flexion and extension. Other examples of hinge joints are knee, ankle interphalangeal joints of the fingers and toes.
* so its a synovial joint...but a Hinge joint type...other types are ball and socket eg: hip etc.
Hope it helps :)
What are the thigh muscles called?
The thigh has 3 groups of muscles:
Adductor - inner thigh, including the adductor magnus, adductor longus, adductor brevis, and gracilis.
Flexor - back of the thigh, including the hamstring muscles, which include semimembranosus, semitendinosus, and biceps femoris
Extensor - front of the thigh, including the pectineus, sartorius, and the four muscles that comprise the quadriceps muscles (rectus femoris, vastus medialis, vastus intermedius and vastus lateralis)
What doesnt belong blood smooth cardiac skeletal?
blood.
skeletal, cardiac, and smooth are three types of muscle tissue
Site of muscle attachment on proximal femur?
It's The gluteal tuberosity and the Greater and Lesser Trochanters.
In your arm
The above answer is incorrect. He/she is referring to the triceps brachii. The triceps femoris is a posterior thigh muscle in Anurans (frogs and toads); though I cannot say that it occurs in all species in the Order.
How muscles and bones coordinate?
In order to move, muscles pull on the joints to pull the bones and let them move.
What part of the body does the bicep move?
The biceps muscle is located in the front area of the upper arm. The biceps muscle helps to stabilize the large bone in the upper arm (the humerus) in the shoulder socket. It also helps to accelerate and decelerate the arm during overhead activities, like tennis or pitching.
The biceps tendons keep the biceps muscle attached to the shoulder at one end and the elbow at the other end.Tendons are strong cord-like structures that connect each end of the biceps muscle to bones. At one end of the biceps muscle, tendons connect the biceps to the shoulder in two places. At the other end of the muscle, tendons connect the biceps muscle to the smaller bone (radius) in the lower arm.
Source:AAOSIs muscle action be voluntary?
We have three types of muscle tissue; smooth, cardiac, and skeletal. Skeletal muscle tissue is the only one of the three that are voluntary.
What exercises really help with your bicep muscles?
Concentration Curl - The Correct Way!
This bicep workout routine requires a single dumbbell. 1. Start by sitting on a bench at the edge, with your legs apart at an angle of 70 to 80 degrees and make sure that the dumbbell is placed on the ground in between them. 2. Pick up the dumbbell up, keeping a straight arm. Rest your triceps on the inner part of your thigh. 3. Bend your arm and 'curl' the dumbbell towards your shoulder. 4. Slowly lower the arm back until it is extended again. 5. Repeat the above steps for 8-10 repetitions 6. Repeat the above for the other arm.
What is the second strongest muscle in your body?
im not sure but i think it is the cervic
The back or lats
Muscles are made up by thousands of fibbers that can contract
As muscles contract then relax they move the bones and limbs at the joint
Muscles also work in pairs
When one muscle contract the other muscle controls the opposite action will need to relax
Muscles are made up by thousands of fibers that can contact
As muscles contact then relax they move the bones and limbs at the joint
Muscles also work in pairs
When one muscle contract the other muscle controls the opposite action will need to relax
Compare and contrast the three types of muscle tissue Which type is most significant?
The three types are: smooth, cardiac, and skeletal. They are all significant, because if anyone of them fail to work, you die.
