What is the definition of protraction in terms of body movement?

Protraction refers specifically to the forward movement of a body part, particularly in relation to the shoulder girdle and jaw. In this context, when you protract your scapulae (the shoulder blades), you are moving them away from the spinal column and forward around the rib cage. Similarly, protraction of the jaw involves moving it forward to create an overbite, which can be crucial for certain behaviors in both humans and other animals.

Understanding protraction is important in physical therapy and anatomy as it relates to various movements involved in exercises, rehabilitation, and daily activities. Recognizing this movement can help in assessing and developing treatment plans that enhance mobility and functional movement patterns.
