Question

question 4
just as individual bones are the organs of the skeletal system, individual muscles are the organs of the muscular system.
true
false
question 5
which of the following is not a posterior muscle that acts on the shoulder girdle?
trapezius
pectoralis minor
levator scapulae
rhomboideus
question 6
poor posture puts abnormal strain on bones and may eventually produce deformities.
true
false

Explanation:

• Question 4: In anatomy, individual muscles are indeed the organs of the muscular system, similar to how individual bones are organs of the skeletal system.
• Question 5: The pectoralis minor is an anterior - chest muscle, not a posterior muscle acting on the shoulder girdle. The trapezius, levator scapulae, and rhomboideus are posterior muscles related to the shoulder girdle.
• Question 6: Poor posture can cause abnormal stress on bones over time, potentially leading to deformities.

Answer:

• Question 4: True
• Question 5: B. Pectoralis minor
• Question 6: True
