Just remember: flexion = forward. This action occurs at many joints and always brings the bones that make up a joint closer together, or closes the joint. Extension is the opposite of flexion, which means it lessens the angle between the two bones or opens the joint.
What is the skeletal template in the human body?
The embryonic skeleton is first formed of mesenchyme (connective tissue) structures; this primitive skeleton is referred to as the skeletal template. These structures are then developed into bone, either through intramembranous ossification or endochondral ossification (replacing cartilage with bone).
Why is it important for nurses to understand the skeletal system?
Understanding the structure and purpose of the bone allows nurses to understand common pathophysiology and consider the most-appropriate steps to improve musculoskeletal health. Citation: Walker J (2020) Skeletal system 1: the anatomy and physiology of bones. Nursing Times [online]; 116: 2, 38-42.
