Anatomy of the Ear. The ear is made up of three parts: the outer, middle, and inner ear. All three parts of the ear are important for detecting sound by working together to move sound from the outer part through the middle and into the inner part of the ear. Ears also help to maintain balance. Share this:
The major skeletal muscle groups forming the upper body are the abdominal, pectoral, deltoid, trapezius, latissimus dorsi, erector spinae, biceps, and triceps. The major skeletal muscle groups of the lower body are the quadriceps, hamstrings, gastrocnemius, soleus, and gluteus. Muscles move by contracting.
Broadly speaking, the muscular system of the human body is composed of three distinct types of muscles-skeletal muscles, smooth muscles, and the cardiac muscle. The skeletal muscles are what we know as voluntary muscles, and these muscles are those, that we can train and develop by using muscle-building methods.The smooth muscles are the involuntary muscles.he skeletal muscles are what we know as voluntary muscles, and these muscles are those, that we can train and develop by using muscle-building methods.
