Question

Start off by going for a walk around the room. Put one foot in front of the other, swing your arms, and let your pelvis rock a bit as you move forward in the room. Now write three sentences, including at least three medical terms, about your body walking. You can include what plane the movement happens on, the names of some joints that move, what muscles or bones are involved in the movement, or any other anatomical or medical terms that you would like to describe your walk. Feel free to look at the diagrams in the unit text or to look up the medical terms on the internet. Part 2 Take your arm and hold it straight out to the side. Now place your hand on top of your head. Again, you will write a few sentences about this movement and these body parts. In your description, include three muscles, three bones, and three regions of the body that are inferior inferior to your hand. Identify the plane of movement that your hand moved on to touch the top of your head, and research whether your elbow uses flexion or extension to accomplish this movement; include these facts in your description. Turn in both written paragraphs.

Answer 1

Part 1: Walking

As I walk around the room, my movements predominantly occur in the sagittal plane, allowing for the flexion and extension of the hip, knee, and ankle joints. The primary muscles involved in the action of walking include the gastrocnemius and soleus in the calf, as well as the quadriceps in the thigh, working to propel my body forward. The bones that support this movement include the femur, tibia, and fibula, while the pelvic region stabilizes my posture as my pelvis rocks gently with each step.

Part 2: Reaching to Touch My Head

When I extend my arm straight out to the side and then bring my hand to the top of my head, the movement occurs primarily in the frontal plane, involving shoulder abduction followed by shoulder flexion. Muscles engaged in this action include the deltoid, supraspinatus, and trapezius, while the bones involved are the humerus, scapula, and clavicle. Regions of the body that are inferior to my hand when it touches the top of my head include the thoracic region, abdominal region, and pelvic region; during this movement, my elbow primarily experiences flexion to allow the hand to reach upward.
