Give three of the major functions of the muscular system
- Skeletal Movement
- Maintain Posture and Body Position
- Support Soft Tissues
- Guard Entrances and Exits
- Maintain Body Temperature
What is the function of a tendon?
attache muscle to bones
Muscles which bend a limb at a joint are called....
flexors
Muscles which straighten a limb at a joint are called...
extensors
Muscles which move a limb away from the midline of the body are called
Muscles which move a limb toward the midline of the body are called...
Describe the different functions of prime movers, antagonists and synergists
Prime movers = Agonists
Muscles which initiate and maintain amovement
Antagonists
Reverse or oppose a movement
Synergists
are muscles which assist a prime mover by stabilising a joint crossed by a tendon, allowing the prime mover to produce more effective movement
Which four muscle groups make up the axial musculature?
- Muscles of the Head and Neck
- Muscles of the Spine
- The Oblique and Rectus Muscles
- Muscles of the Pelvic Floor
Why is it unnecessary for the spinal column to have a large group of ventral flexors?
- many of the large trunk muscles flex the vertebral column when they contract, and
- most of the body weight lies anterior to the vertebral column, so gravity tends to flex the spine.
What is the function of the appendicular musculature?
Stabilising the pectoral and pelvic girdles and for moving the upper and lower limbs.

- Trapezius
- Levator scapulae
- Phomboideus minor
- Rhomboideus major
Name the muscles that position the shoulder girdle in anterior view
- Subcalavius

Name the muscle of the gluteal group in lateral view
- Tensor fasciae latea
- Gluteus maximus
- Iliotibial tract
Label the direction of muscle action
- Flexion and abduction
- Extension and abduction

Name the two muscles of the group of Iliopsoas
- Psoas
- Iliacus
The Psoas and Iliacus are often referred to as the...
