Gross Anatomy
Student Discussion Assignment
As with the skeleton, muscles are organized into the axial and appendicular musculature. The axial muscles provide movement, support, and protection to the axial skeleton, while the primary responsibility of the appendicular muscles is to provide movement to the upper and lower limbs.
Similar to Week 6, the overall learning objective for Week 7 in the laboratory course is to identify and describe the superficial muscles on your body as well as the movement they produce. More specifically, we will work to identify and describe the antagonists of the major prime mover muscles. To successfully complete this assignment, first read the following exercise from the Laboratory Manual: Exercise 13: Gross Anatomy of the Muscular System.
Student Discussion Assignment
Briefly identify, list, and describe the action of at least two of the following muscle types:
superficial (i.e., two anterior and two posterior) muscles
head and neck
anterolateral neck and throat
thorax and shoulder
abdominal wall
Briefly identify and list antagonists of the major prime movers associated with each muscle described above.
Write your responses in a minimum of 250 words in APA format and include your references.

The abdominal muscle provides postural support, protect internal organs in the area and enable flex and rotate the trunk. They comprise of:
Rectus abdominus- this muscle arises from xiphoid and costal cartilages and runs to the pubic bone at crest and symphysis. They function to flex the lumbar spine and tilt the pelvis. It also enables forced expiration and increases intra-abdominal pressure.
Transverse abdominis- It is the deep muscle and runs from lower costal cartilages, thoracolumbar fascia and lilac crest……………………….
