Muscles Affecting the Upper Arm

  Many different muscles help control movements in the upper arm. The thorax serves as a major anchor point for each of these muscles. The most substantial anchor points in the thorax include the scapula, clavicle, sternum, and ribs. Much of the discussion in this topic refers to anatomical names for movements. If you are Read More …

Smooth Muscle

Smooth muscle is found in organs and blood vessels throughout the body. Because these muscles help with organ function they cannot be controlled by conscious thought. The autonomous nervous system controls these muscles, making them involuntary muscles. Differences Because these muscles are not involved in locomotion, structural support, or fast action these muscles are quite Read More …

Cardiac Muscle

Cardiac muscle and skeletal muscle have a great many similarities. They also have a number of significant differences. We will primarily cover the differences in this article. We assume that you have already studied the nature of skeletal muscles. Cardiac Muscle Fiber Cardiac muscle is only found in the heart. The muscle fibers (cells) in cardiac Read More …

Anatomy – Muscular System

We continue our anatomical studies by exploring the human muscular system. Students will explore muscle types, muscle tissues, muscle functioning and interactions, muscle groups, muscle metabolism, and the various muscles found in the body – particularly those that control movement of major areas of the body. This is perhaps the most complex area of anatomical Read More …
