The knees is known as a hinge joint, as it can only bend in on direction when it's bent. while the knees is bending the muscles in the leg are expanding creating a wider stride, when the legs comes back the muscle contracts.
The actions skeletal muscles can perform are: flexion, extension, abduction, adduction, rotation, elevation, and depression.
Protraction of the scapula, produced by actions of both the serratus anterior and pectoralis minor muscles.
Muscles within the brachium are responsible for the extension of the elbow. These muscles also work for the flexing of the arm as well.
The bones involved in long jump are the femur, fibula, tibia, vertebra, metatarsals, phalanges, ulna, radius, and the humerus. The muscles used in the same activity are the gastrocnemius, glutes, quadriceps, hamstrings, biceps, deltoids, triceps, trapezius, latissimus, dorsi, quadriceps, and the abdominals. It also includes the elbow, shoulder, and hip ball and socket joint, the elbow, patella, and toes hinge joint, and the ankles condyloid and synovial joint. The joint actions are flexion, extension, and abduction.
extension, contraction
Flexing the thigh, extending the leg, adducts leg
Periodic rest and relaxation for the muscles involved in repetitive action.
The main muscles that are involved in a splenectomy are those in the diaphragm. The spleen is located under these muscles.
Which of these muscles is not responsible for flexion or extension of the arm?
An agonist muscle is a muscle that plays a part in the extension of a muscle. The agonist muscles for a knee extension are the quadriceps and hamstrings.
yes brain i s involved in reflex actions as it makes a pathway for sensory neuron to connect with and brain then directs the motor neuron to take a particular action which is given by effector !(muscles)
There are many: extension, flexion, supination, pronation, abduction, adduction, lateral rotation, medial rotation, circumduction, elevation, depression, protraction, retraction, inversion, eversion, and opposition.
