BASICS BIOMECHANICS

Human march is a process of movement in which the human body in an upright position, moves forward, a supported weight being alternately by both legs

The position is one in which act the different segments of the body and will be aligned correctly, generating a minimum of stress on the body's tissues and involves an expenditure of energy, minimum

the knee is a synovial joint with a mechanical architecture that includes two joints one patellofemoral formed between the femur and patella and tibiofemoral between the femur and the tibia

SURFACES

The joint surfaces are the distal femoral epiphysis, femoral trochlea or patella facet on the front, femoral condyles, proximal tibial epiphysis

Is a bony box formed by the sternum, ribs, costal cartilages, ribs, and the bodies of the thoracic vertebrae

It is each of the tips are fixed to the upper body. It consists of four segments: shoulder girdle, arm, forearm and hand.

COMPONENTS

It is offering a total of 32 bones and 42 muscles; vascularization is the responsibility primarily of the branches of the axillary artery, the main veins are the cephalic, basilica and axillary; most of its innervation is in charge of the brachial plexus.

it is a ball and socket joint, joint with three axes and three degrees of freedom

COMPONENTS

transversal axis in a frontal plane movements in flexion and extension, anteroposterior axis in a sagittal plane movements of abduction and adduction and a vertical axis and retropulsión antepulsion movements with the arm abducted 90 ° and a fourth longitudinal axis of the humerus with and rotation movements internal and external rotation

The articular surfaces are the humeral head and glenoid fossa of the scapula

Its passive stabilizing elements are the capsule, middle glenohumeral ligament, upper and lower, coracohumeral ligament, tendons of the subscapularis, supraspinatus, infraspinatus and teres minor. Liabilities stabilizers are the humeral head and the muscles of the rotator cuff tendon of the biceps long and short.
