Pairs of skeletal muscles work together to help you move. The muscles contract and relax when your muscles go in different positions.

Parts of the Muscular System and their functions

2015-04-24 15:29:33 UTC

Frontalis: serves for facial expressions

Trapezius: moves the scapulae and supports the arm

Deltoid: it is the prime mover of the arm abduction along the frontal plane

Rectus Abdominus: flexes the lumbar spine, assists with breathing and is important in respiration

External Oblique: pulls the chest downwards to compress the abdominal cavity

Sartorius: helps flex,adduct and rotate the hip

Zygomaticus: controls facial expression

Sternocleidomastoid: flexes the neck and helps with the oblique rotation of the head

Pectoralis Major: helps with the movement of the shoulder joint

Biceps Brachii: helps control the motion of the shoulder and elbow

Gracilis: responsible for hip abduction and also assists knee flexion

Adductor Longus: Controls the thigh bones ability to move inward and sideways

Rectus Femoralis: helps extend and raise the knee

Vastus Lateralis: Extends the lower leg and allows the body to rise from a squatting position

Soleus: plantar flexor of the ankle
