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.
Best Answer: There are three muscle types: skeletal, cardiac and smooth muscle. 1. Skeletal muscle: refers to most muscles that are under voluntary control. These are cylindrical and often pretty long (because they are multinucleated), with the nucleus on the edge of the muscle so as to not interfere with contractions. 2. Cardiac muscle: refers to the muscles of the heart (cardiomyocytes).
