Question

3. When comparing the picking up of a full one-gallon container of milk versus picking up a pencil, explain why and how your body varies the strength and effort made by your muscles when picking up a full one-gallon container of milk? What changes about this when picking up a pencil and why? What would be different if we were to write with the pencil instead of just picking it up? And why?

Answer 1

Q1: strength and effort of muscles while lifting one gallon of milk:

1. Anterior deltoid

2. Posterior deltoid

. 3. Triceps brachi

4. Foramen flexor

5. Foramen extensor

6. Brachioradialus

7. Supraspinatus

8. Infraspinatus

While picking pencil:

1. Extensor radualis lounging

2. Brevus

3. Ulnaris

4. Extensor digitorum

5. Indicis

6. Lumbricalus

7. Flexor dugitorum

Changes:

1. Main difference is with weight and size

2. Pencil is small and light weight so it does not require high muscle power.

3. So we can pick pencil easily and it requires much nerve stimulation, from peripheral muscles.

Writing with pencil:

1. Writing with pencil need nerve stimulation as well as muscle power.
